Lessons Learned, Schmessons Schmearned: Part 1

After a lengthy rebuilding of the rear end on the E30 (something we’ll get into later), the Rivals met their first rival when they hit the ground for the June 20th Tri-State Sports Car Council TrackSprint at Autobahn Country Club. It was their first event of the season in this new COVID-19 world and our first opportunity of the year to embarrass ourselves in front of better cars and better drivers. But in the shadow of such daunting things, there were bright spots. Like when you smack your palm against your face hard enough to see bright spots.

Lesson Learned #1: Install Your Car Parts Correctly

The night was a short one for everyone. With it only being a three-or-so hours, you still get a lot of track time when everything goes perfectly. But timing tent issues and weather acted like a COVID-19: 2 on the nights activities. Conveniently dramatic strikes of lightning played before us like a movie as we came around our favorite turn, The Kink. The looming rain clouds seemed to sneak up on the entire event because our car and the two or three that were released behind us were the last to touch the track that night. It seemed like only seconds after re-entering the paddock, torrential rain hit.

Out of a potential ten, our night consisted of a whopping three laps. Rain aside, we lost a session to the incompetence of your author. The backwards installation of a throttle cable retainer was the accomplice in this case. Slamming the car into second gear after getting that exciting “go” signal from the start line could be likened to getting walked in on by your mother when your just getting to that special scene in James Cameron’s Titanic. The car fell flat and we idled gently to a stop in the grass on the outside of Turn 1. We could immediately feel in the throttle pedal that something was no longer connected and since the engine was still running, it didn’t seem like we’d fallen into a worst-case scenario. For our safety and theirs, we stayed in our car and let the services do their thing.

When we made it back to the service road we popped the hood and found that the throttle cable had simply popped out of the retainer. Being confused as to why it had popped out at all, we chocked it up to they-don’t-make-them-in-West-Berlin-like-they-used-to logic and recycled a small flip-up notepad for its wire and safety retained the throttle cable end into the plastic retainer. Ever so proud and narcissistic of ourselves as usual, we posted the humble repair to our Instagram. Our friend @robotron, with the graciousness and humility of someone who courtesy flushes the toilet, let us know that as heroic as our repair was, if we’d installed it correctly it would’ve never failed. We owe him our lives and our first born children.

Lesson Learned #2: Mufflers – For Your Health

After re-establishing the rear end, the exhaust was re-installed without the muffler. Enjoyment of the sound being of paramount priority, we decided to leave it off and took it easy getting to and from the event so as not to attract unwanted police attention. Without the auditory padding of the rear interior in place, that sound becomes more than a drone as it became a genuine pain. Fortunately, because of the authors habit of hoarding PPE from job sites, we had a set of earplugs in our backpack to save our hearing. The next time we raced, the muffler was pleasantly and jubilantly installed. The ride home was by comparison, delightful. Not unlike falling asleep amongst the gentle embrace of your favorite spouse. Everyone has more than one spouse right? Am I in a cult? Please help me.

Lesson Learned #3: A-B-R-B-R-R-R-D-P-L: Always Be Referring Back to RYE30 Racing’s Race Day Preparation List

Because we’re as clumsy as we look, our phone has been “upgraded” since the last time we raced, which means the notes entry we always used to make sure we had everything ready for the next track day had pined for the fjords. But lo! We remembered we posted once, neigh, twice, what we believed to be the most useful list the average autocrosser will ever need: Preparation – R: The Best Way to Prepare Your Ass for Seat Time on Race Day. We opened the link and within the hour the car was packed and ready to go. So simple. So organized. So RYE30 Racing. If you make it out this season and you need a list that’s optimized for performance and fun, click that link, because we think we’ve got you covered.

Those are the few lessons learned from the few laps we had the opportunity to complete. The night was awesome nonetheless. The friends we got to see again and the friends we made were worth the trek alone. We always recommend racing for those reasons alone.

Preparation – R: How to Prepare Your Ass for Seat Time on Race Day

Because race season is officially underway, with registration officially opening this weekend for some Midwest autocross events, we thought we’d repost our article on getting ready for race day!

For those of us who aren’t temporarily embarrassed millionaires, race days are about having fun and not clutch-dumping a career. Use our list as a guide to help you focus on having fun and not cursing the Sun on race day.

It won’t go without saying that you should have two things sorted before deferring to this list: Bring your friends and be reasonably sure that your car will make it home afterwards. Going autocrossing without a friend whose company you simply enjoy, or is a co-driver, is like going to the bathroom by yourself. Who’s going to hand you toilet paper? Who’s going to remind you that you need to wash your hands? Most importantly, making sure the car gets home afterwards should go without saying. Don’t let foreseen consequences turn your free weekend into a how-am-I-going-to-get-to-work-on-Monday pity party.

Friends, Food, and Canopies

Standing around in the hot sun is for lizards. Since we don’t often see any of our underworld overlords at these events, we sprung for a small 10ft x 10ft canopy. Not surprisingly, our Harbor Freight canopy came with subpar staking hardware so we grabbed some heavier duty ones from a hardware store. Altogether we were only out $60.

The unintended and welcomed consequence was that we became a magnet for the weary sun-faded autocrosser. We were an entertainment hub for the rest-period racer with our tantalizing conversation skills, good view of the course, Bluetooth radio beats, and tuned-in two-way radios we used to listen to track times.

We race in and around the Chicagoland suburbs, so food and drink are never far, but we bring a cooler for drinks and snacks nonetheless. Take lots of water, sports drinks, and snack bars. If you’re inclined to do so on your rest period, hit up a local spot and support the local business. The club we usually participate with asks you to donate your receipts to a small recycled baby wipes container at the timing tent to show the municipality that we contribute to the economy if ever we were to get on the wrong side of the local Karen squad.

Essential Essentials

Sample Tools – Photo Courtesy of Duncan Millar

If you don’t expect anything catastrophic to happen to you or your car, then leave the defibrillator and engine hoist at home. The picture above shows a small kit we brought to use for tightening the wheels and for experimenting with advancing and retarding the intake camshaft. We also usually take a small assortment of common sockets and wrenches (3/8″ drive, 10mm-17mm), and other regular hand tools like screw drivers and pliers. That saved us last summer when an alternator housing screw backed out into its own cooling fan. It didn’t save us when the timing chain case profile gasket failed and our last stop at the finish line preceded a plume of white smoke. Fortunately the car survived the trip home as the coolant leak wasn’t as bad as we thought. Pack light by just bringing the basics.

Tire pressures should be taught in schools right along side how to manage your finances. The mitochondria is the powerhouse of the cell, but if we don’t have enough grip, how can we effectively put that power down? Take an air supply, like an air tank or portable air pump, and a pressure gauge with so you can add or subtract air as needed. Pressure gauges with the convenient release button on the side are nice, but not necessary; pen gauges work just fine. Rule-of-thumb is that lower tire pressures help provide grip by giving up more rubber along the width of the tire, but too much can roll the tire over onto its sidewall and thus, negate the lower pressure’s effect. Do research on your specific tire to see what its limits are. Remember too that you gain about one to two PSI after heat builds up in the tire. Consider that when you’re setting your pressures.

Dogs were made to have their pictures taken. Make it a true family affair by bringing your dog, your partner’s family, their dog, and enough water for all.

Take pictures with whatever you have, but if you have a DSLR that’s collecting dust, bring it out and test your know-how by playing with the manual mode. Leave your ISO low, and expect to adjust your shutter speed and F-stop (iris size) a lot because of the rapidly changing car and weather conditions. Consider your safety first and make sure you’re not in the “oops” path of any of the drivers. Stick to the outskirts or the designated areas where cone-catchers are posted.

An Intimate Setting – How to Dress Sexy When You’re in the Driver’s Seat

Loner helmets tend to be a bit…musty. For low stress driving events like parking lot autocrosses, you can get away with wearing any helmet you want as long as it’s not a bicycle helmet or one of those that infants wear to shape their skulls. Road course events on the other hand, will more than likely look for a Snell rating and consequently tag your helmet with an inspection sticker. If you’re sunglasses snobs like we are, bring a pair of polarized shades to stuff under the visor for those glare-heavy days.

Wearing gloves is all about preference. For the driver seen in the photo above, it’s more about fetishism, but you’ll catch that story in a different blog. Some find gloves to be too bulky or too sloppy. All understandable given the standardization of sizes and the un-standardized sizes of hands. Don’t worry about being required to wear gloves until you get to wheel-to-wheel events.

Print out a course map to tape to your dash as a quick reference before you hit the go button at the start line. Nothing will replace walking the course before-hand, but every little bit counts. Use the tape you brought to artistically apply your driver number to the windows or doors of your car, to stick it to the dash. Congratulations, you’re now a professional race car driver.

Preparation-R: Dont’ Forget your Decorative Meat Tenderizer

Lastly, it wouldn’t go on the list if we didn’t think it was essential to having fun on race day. Don’t forget your multi-purpose decorative butt plug and meat tenderizer to help you de-stress after each run. Carry it in a fanny pack or have your co-driver standing by with it on a small red pillow for a fanciful touch. A little bit of olive oil will aid installation.

Go race your E30!

The Who, What, Where, and Oh-My-God Why of RYE30 Racing – Team Profiles

A group of crows is called a “murder”. Pretty metal. A flock of E30-racing autcrossers is called a “dufus.” Membership in this elite organization is limited to the ranks of those who are most willing to sacrifice their precious time, effort, and dedication to safeguarding the sanctity of the bottom of the timing sheet. Please enjoy these interviews with the three co-conspirators of RYE30 Racing. Michael first answers what the meaning of life is, Andy tells us about being asked to leave, and Duncan almost cries at the thought of friendship.

Michael Shadle – Weaboo, STI Enthusiast (the car), Lover
Michael and I went to high school together. Our time there was almost identical in experience to that of High School Musical. I was Corbin Blue and he was Zach Efron. He drove a 2nd generation Mazda RX-7 and I have struggled to ever since, be as cool. We’ve recently rekindled our automobile romance and teamed up to build and race the E30. Hopefully you’ve got a dry pair of panties to slip into after you read this; he’s in a band. He daily drives a 540 bhp Subaru Impreza STI and his spirit animal is Keiichi Tsuchiya.

Andy Mullins (“A.M.” for short) – Scientist, Rust Connoisseur, Flat Cap Kind-of-Guy
A.M. and I have a memory of our first meeting not unlike the kind of story you would tell your grandchildren. There was coincidence. we’d both driven our Miatas to the same autocross. Despair! My co-driving sister and I pointed out to him that his rim was bent. Awkwardness. He became angry, and then disparately nonchalant. That emotional roller coaster never ended, and 10 years later we’re still best friends. A.M. is a biologist by trade, has the most impressive motorsports resume out of the three of us, and his project-car Alfa Spider is coming along just nicely. Thanks for asking.

Photos courtesy of Andy Mullins

RYE30 Racing: Tell me about your time in pit crews?
A.M.: Too many individual stories for a short Q&A. We raced SCCA Spec Miata, STL, some endurance racing, and finally GT racing. Won the June Sprints once or twice, don’t remember. Won the Cat Nationals a few times, Blackhawk was easy for us. I have fond memories! Those were some super long weekends, a lot of time spent away from home. The work was physically exhausting but (although the pay was just alright) very rewarding. I used to come home from Road America after a 3+ hour drive a sweaty, tired, dirty mess, but sporting a huge smile on my face. Then I would pass out on the couch and be sore for a week. 

Working as a young race mechanic taught me the importance of hard work, commitment, loyalty, and discipline. Those are values that propelled my professional life outside of motorsports in a way I couldn’t even imagine when I first turned a wrench. I am forever grateful to my team. 

RYE30 Racing: What was your first automotive event?
A.M.: As a participant, or as a viewer? My earliest memory of an automotive/motorsport event as a viewer was in Brazil. We used to have a vacation home in the mountains where they held a yearly hill climb event, they had some Subarus and Indy Cars (it was a Penske, I remember the day-glo orange of the Marlboro hurting in the eyes when hit with the sunlight) parked in the central square. Those are some good memories. 

As a participant I’ve first tried karting early on, it was an indoor track with silly little gas powered karts (EV karts weren’t a thing) but structured like K1 speed for corporate events and parties and such. Lost steering coming out of the straight and crashed my kart hard on a column, so hard that I cracked the kart’s frame in half. 
They kicked me out for the rest of the day, which was probably the smart thing to do.

RYE30 Racing: If I say you name three times in a mirror, what will I see?
A.M.: Yourself. 

RYE30 Racing: Which do you like better? Karts or cars?
A.M.: Karting is the king of motorsports, home of killer machines and athletes. It is an incredibly demanding activity, requiring you to be in top physical shape. Shifters are just impossibly quick, requiring superhuman coordination and brute strength. Laydown karts and superkarts murder people at 110+ MPH in full car tracks. 

Unfortunately Karting in America is a terminally-ill sport battling a few issues:

First: Image. Despite the extreme nature of the sport, most American enthusiasts don’t perceive karting positively. The enthusiasts’ exposure is on indoor tracks, low performance yard karts, or casual video games. 

Second: Accessibility and culture. There are not many outdoor kart tracks left with an open-model of arrive-and-drive, it’s getting harder and more expensive to find places to race. Most people you race with are hyper competitive, in it to win it no matter the cost. Those are some terrible people to hang out with (rare exception: Some grassroots-level racers and families, vintage karting. Love you, VKA crew) so the all important cultural aspect of any sport is just… Not there.

Third: Retention: Karting has a weak foodhold in the USA as a long-term sport. It’s always been framed as an entry level thing you graduate from, but that spot is now filled by racing sims and autocrossing – both having much, MUCH higher adoption rate, ease of access, and lower entry level/maintenance costs. So people do karting for a little while, then leave to do something else. 

Cars are stupid, but at least I can race in more places and drive them on the street, without having to trailer a kart to a track hours away (the nearest autocross lot is less than 10 minutes from my house.) Started on vintage Italian/Swiss karts, [then] got really into vintage Italian cars. When the right opportunity came to own something special, I bailed. You don’t have to look too close to find residues of my past karting life on my current build.
 
RYE30 Racing: Spell “ICUP”. 
A.M.: No.

Duncan Millar – Aspiring Cult Leader, Vegetarian, Identifies as an M42
Knowyourmeme.com knows it simply as the “Spider-Man Pointing at Spider-Man” meme. Imagine a gaggle of Spider dudes pointing at each other and you’ll have the following interview with RYE30’s author, editor, photographer, publicist, fluffer, and sous chef, Duncan Millar.

RYE30 Racing: How long have you been involved in motorsports?
Duncan: If I were to put an official date on it, I’d say summer 2009. That was the first time I autocrossed with my ’90 black-and-red rattle-canned Mazda Miata. I was only 20-ish by then but I remember regretting wasting as much time as I had, not racing. It was as inexpensive and accessible at the time as it is now and I wish more people would consider doing it!

RYE30 Racing: Would you consider yourself closer in comparison to Ryan Reynolds or Ryan Gosling?
Duncan: I think that’s an easier question to answer than you think. If I were to answer it respective to his looks and his capabilities, I would tell you to consider Ryan Gosling’s filmography. His brooding, like mine, is integral to his method. Blade Runner 2049. Drive. I often find myself staring out a window, reminiscing motionlessly, and let me tell you; I get chills. And not just because it’s February and I have that window open.

RYE30 Racing: Realistically, what would you be racing now if you didn’t have the E30? Unrealistically?
Duncan: I think realistically, if I were better with money, we’d be in a Lotus 7 kit car. A LoCost or something similar with a Miata drivetrain. Or we’d be in some sort of spec series like Spec Miata, or taking a more serious dive at LeMons racing. Unrealistically? Pod-racing.

RYE30 Racing: What is your mission with the RYE30 Racing brand?
Duncan: Each one of us would love more than anything for this hobby to turn into a career. Procrastination had gotten the better of me in particular and I finally convinced myself that too late was going to be when I took a dirt nap, so I got together with my guys and asked if they wanted to be a part of making RYE30 into something that could hopefully one day become bigger than us, and they were more than willing.

To say tangibly what we want to do with the brand is to say that we want to race. We have the skill base between the three of us to get out on the track and ideally become a traditional race team; drivers, a pit crew, rubber, development, and wins. If we can mold ourselves into something that companies want to throw sponsorship dollars at, that would be the ultimate goal. In the meantime, we want it to be a source of giving back to the community what all three of us have been given from it. Knowledge and bad jokes.

RYE30 Racing: Is that you in the Weinermobile?
Duncan: Why, yes it is. A friend of mine’s brother drove it for a year on contract. The experience was the closest to a religious one as I believe I’ll ever get. Fun facts about it: it’s built on a gas-powered GM 6500 series frame, it’s automatic, and it’s loaded with the little weiner-whistles.

Can’t Stand Your E30 – How to Assemble a Stand and Mount Your M42 Block

Another lesson in frugality incoming: We picked up an early E36 M42 engine for $250 down in Indy for purposes unknown to use at the time. It was fortuitous however because we ended up using its cylinder head after the dreaded faulty profile gasket fault made itself apparent during a July 2018 autocross. We turned in our bad cylinder head as a core-return at local junkyard where we found a good replacement and now we have a fully unfunctional E36 M42 again to make an example of for you fine fuc…folks.

Step 1: A.B.C. – Always Be Craigslisting – ALWAYS BE CRAIGSLISTING

Photo Courtesy of Duncan Millar

Engine stands are cheap. Even brand new. We overpaid for our Harbor Freight brand “Central Machinery” stand. Rated at 750 lbs, it’s over-qualified, but for $40 on Craigslist, isn’t as great of a deal as we’d like considering we could get one for under $50 with a coupon and we’d have a warranty.

Step 2: Engine Stands – Assemble

Photos courtesy of Duncan Millar

The stand is essentially made up of two parts. The mounting bracket that sits in the head tube, and the stand itself. The stand is made of three parts. The two rectangular sections have the caster wheels and the other houses the mounting bracket. In our example, the two rectangular sections are already bolted together with the included hardware we received. If you’ve misplaced yours or never received any, they’re easy to replace (check your leftover nuts-and-bolts bag or buy new ones) and don’t require a specific thread because they’re slipped through simple through-holes.

After those are bolted together you can bolt the mounting bracket section to the wheels. Ours has a nut welded inside the bottom of the tubing to tie it to the wheels. Put the longer bolt through the wheels section and into the bottom of the mounting bracket section. Now you have a completed stand. If you have this stand in particular and you don’t have that bolt, it’s an M12x1.75 and approximately 100mm with a locking washer.

Step 3: Stick it to Me – The Mounting Bracket

Photos courtesy of Duncan Millar

The mounting bracket simple slips through the head tube on the mounting bracket section of the stand. Each of the four arms is adjustable. Again, if you don’t have any included hardware, hit up the nuts-and-bolts bag. These M12x1.75s might not be found as easily in your leftovers, so measure the lengths you’ll need and hit the hardware store. With ours we needed four shorter ones (about 3″), four longer ones (about 5″), and four nuts with washers.

With the block on a stable surface and all of the arms loose, mock-up your bracket thusly; bolt the bracket to the block hand-tight and then get the other side with the tube as square to the block as possible so that they are evenly horizontal to each other. Hand tighten those bolts and nuts. After that, tighten the bracket to the block fukentight and then tighten the tube section gutentight.

Put a towel down and grease up the head inside of the head tube. In your best parody of German porn, grab a friend or six and lift the block with the mounting bracket attached, and gently slide the whole thing into the head tube of the stand. Celebrate the event by sliding the swing lever and locking pin into their appropriate holes at the end of the tube. You’ll use those to lock the block in place and swing it around on its axis when necessary.

Word of advice whenever you do so, use two hands! A fully loaded engine is going to be very top or bottom heavy and will leave you in the dust when you try to rotate it. One of these we’ll get around to rebuilding our M42 and hopefully provide you with more scintillating and Pulitzer Prize worthy innuendo.

Spring Steel, Spray Paint, and Salvage: Our Anti-Roll Bar Brackets Get a Makeover

We have a friend named ‘Josue’ that we call ‘Sway’ for short. We can count on him to not let us down, unlike these sway bar brackets have.

Long term viability was not our strong suit in the early days of turning our once daily-driven sex-mobile into an inbred racehorse. Midwestern winter driving and near-SpecE30 suspension mix like Virgos and Scorpios. Which is to say that astrology is all made-up as it goes along and we shouldn’t have been driving this car in the winter. The parts that took the beating in particular were ones with a thin, eBay quality epoxy coating or none at all. In other words, all of them. Since we took the front ST anti-roll bar out with the fingers-crossed promise that we’d refinish the brackets, we took the opportunity to do just that in between some work on one of our significant-other’s work-and-school-mobile.

If you’re familiar enough with stock E30 suspension, you’ll notice the differences immediately. The original bracket leverages into place inside of the front subframe and then bolts into place to semi-permanently secure the bar. Because the replacement performance part is slightly larger in diameter and experiences higher torsional forces (that’s us making it up as we go), it came with a special bracket assembly that helps brace it flatter against the subframe with a large backing plate and a bracket that bolts into the original bolt hole. It also dual-purposes one of the subframe bolts.

Step 1: Safety First, Second, and Fourth (Third is Lunch)

Photos courtesy of Duncan Millar

As with any operation involving swinging phallic equipment attached to something with too much energy, you’ll want protection. Since we’re using our Harbor Freight bench grinder with included Harbor Freight wire wheel, safety glasses, underneath a face shield, behind ballistic glass would have been the wise decision. But for now, all we have are safety glasses. Gloves are generally not advised for using with rotating equipment, but since the actual bracket portion of the bracket assemblies are awkward to hold, we took the risk. Refinishing the other parts of the bracket was easier because of their straight-forward shapes.

Step 2: Stripping – Taking it all Off to Get Us Through Vocational School

Foreseeing difficulty in attacking these with the bench grinder, we took a whack at them with a nylon wheel and a hammer drill. The nylon wheel had been great at removing the surface rust on our cast iron lathe chuck because it removed it briskly and without damage to the chuck itself, but against the thick rust of our unknown-alloy steel brackets it was almost useless.

Photos courtesy of Duncan Millar

To the bench grinder we went. For the brackets, we made sure to get to the insides, outsides, and sides. This would seem obvious, but it’s easy to get caught up in this oh, so shiny metal as it appears before your eyes that it’s easy to skip the quality checks before you move onto the next piece. The part wasn’t as difficult as we expected it to be, but it did take some unusual angling to get to all the nooks on the piece. Specifically, on the outside of the bracket where it bends at 90 degrees. A tip for wheeling the smaller components like the washers and the fasteners; place them in a set of locking pliers. For the nuts and bolts, we spun them together with a fair amount of hand-tightness and ran them against the wire wheel without touching the threads. You’ll remove the special coating that accompanies hardened fasteners like these and will make them more difficult to remove the next time you need to (sometimes even with the application of anti-seize materials!).

After about 20 minutes of tiny projectiles to the stomach and a podcast we couldn’t hear over the drone of the bench grinder, everything was looking as if it had been freshly cast in a medieval blacksmiths forging facility. Blacksmithery? Correct us in the comments. Someone. Anyone. Please read our blog! Anyway, on to paint they go.

Step 3: Epoxy Paint Me Like One of Your American Anti-Roll Bar Brackets

Previous projects on our Alfa Romeo Spider left us with more than enough black epoxy paint. We double-fisted each pair of components on some bailing wire and coated each one three times. Normally, we wouldn’t coat the threads of a fastener with paint because it can negatively alter those threads capacities to have torque applied to them. In other words, they won’t tighten no good no more. But since we had the nylon nut already covering the only area of thread that it would ultimately be engaging, we went ahead and painted it with the intention of it being a rust preventative maintenance.

While we let them air dry between each application, it’s important to let them cure for whatever period of time is suggested on the back of the can. Since we won’t be installing them again any time soon, we let them rest on the bench to do the requisite curing, hoping all the while that they spring to life the moment we close the shed door and go on a Toy Store like adventure in the time it takes us to eat, sleep, kiss our loved ones (and pets), and return to the shed for the continued torture of not being inanimate objects that become sentient in the absence of people.

We hope you had a happy holiday season and that you slayed many no matter what belligerent you fought for in the war on Christmas.

The Giant’s Despair: Climbing the Hill in Wilkes-Barre, PA

We’re taking a holiday break to reflect on all of the parts we should’ve bought ourselves instead of buying gifts for others. This is a short essay we were inspired to write a few years ago when we visited the Giant’s Despair Hill Climb site in Wilkes-Barre, PA while on a job. Enjoy this essay, and enjoy the war on Christmas, no matter what side you’re on.

The height of the climb is a ghost of the yearly event. Just outside of Wilkes-Barre, Pennsylvania, mud and cleared trees on the north edge of the road, where timing officials and spectators have matted the terrain, are adjacent to the permanent finish line spanning the breadth of the two-lane road. Just beyond its peak, a shining building I only caught a glimpse of in passing. A fortune-telling of the dynamics I would experiences as I made the journey down the road and through the town at the bottom of it.

Doing my best not to turn my rental Mazda 6 rotors into french fries, I cruised down the steep decline, taking in the view of the valley as my sinuses rapidly compressed. The first major turn came with plenty of warning that I simply had not headed. A sharp, banked right-hander made me do my best Cousin Eddie ‘woo!’ impression to the audience of empty seats in my sedan.

I won’t bore you with the details of the remaining ride because the obvious gem is the uphill. Tumbling out of the straightaway at the bottom, an officially named “Giant’s Despair” park simultaneously greets you and waves ‘goodbye’ with its brevity. Down through what feels like a landlocked seaside town, you wouldn’t be surprised to see someone taking a wicked pissa outside one of the countless (and windowless) bars. And almost as if the same poet that named the Giant’s Despair had been the city planner, the scenery changes drastically as you pass over onto the other side of the tracks. Porches and abandoned cars in driveways turn to projects and abandoned cars in parking lots. A pair of police cars turn off their emergency lights and disband as I pass through the first major intersection. I imagine the demarcating tracks separate color more than they do class. An unfortunate juxtaposition to the thrill of the nearby hill.

I turned around in the lot of the B’nai B’rith Senior Apartments and dodged potholes that would make a Chicagoan proud, as I made my way back to the starting line. By the time I arrived, it was just after dusk. Into manual mode I went, and up the hill and away from the despair I’d climb. The ascent was fantastic. Quick dips that turned into almost-hairpins and frequent undulations through the straighter portions of the steep grade made me feel like I was escaping feds in a cigar boat.

I reached the top and and book-ended my trip with the shining building; a building I’d come to realize was an adult addiction rehabilitation clinic. I felt the road was not the despairing one, but the region itself. Perhaps in naming it, they’d meant to embrace their trials as a method of coping. If you asked me where to start and end the course, I’d tell you to start at the bottom and work your way to the top as best you can like the rest of us. The finish line is up there somewhere and I hope we both make it.

Where Will You Hide When the Revolutions Come? A Proletariat’s Guide to Tachometer Installation

Cowering behind the steering wheel, you wonder if with all of the abuse you’ve reaped on your engine, will you be held to account when the guillotine (or ‘clutch’ in this metaphor) finally drops?

Beyond the faded paint, and rusted door corners. Beyond the hibernated, storage-unit affair of its interior.

A purveyor of the most vital information besides water temperature, engine speed is an essential diagnostic measurement for maintenance and reference for track driving. Our preference is for a digital, as opposed to analog, readout of that information. We found a home-grown LED counter and sweeping shift light combination called the “SL10” on eBay from a French seller (and designer) named rgtracetech883 with a tonne of functionality for it’s size and price. But you can use any you prefer as long as it can read a 5 volt or higher pulse signal and be powered from a 12 volt system.

Even if you only have a tentative understanding of electricity, this really isn’t that hard! We’ll try not to drone on about theory, but getting you to understand your car (whether it’s an E30 or not) is what we’re here to do, so no promises. In this case, we’re going to try not to bore you with the installation of this simple power/ground/signal tachometer.

Step 1: Unfuck the Cluster

Photo courtesy of Duncan Millar

If the first word you think of after “cluster” is “fuck” then you’ve come to the right blog. We pulled this entire dashboard out for what was ostensibly no reason once, and in subsequent efforts, just the cluster at least a dozen times, so a few steps might be missing since we’ve left a few things out to streamline the process. As you’ll see in the picture, the plastic trim panel that hides the manufacturing nether-regions below the cluster has already been removed (and misplaced). After you’ve navigated to a better resource and figured out how to remove the outer-most panel, grab a PH1 screwdriver (or bit, extension, and impact gun) and remove the four screws imprisoning the bezel. Once that’s removed, there would normally be two more screws holding the cluster itself to the ceiling of the dashboard. Pop those out and get to wigglin’.

It’s in there pretty tight. This is normally where we’d say “that’s what she said” but our adjacent German-language erotic Scott Pilgrim fan-fiction blog only comes out once a month and we don’t want to spoil anything for you by going on a tangent. We found that if you pull up on the bottom, and swing it in towards the front of the car, you can use the space inside the dash to point the face at the floor and eject it like a DVD of Paul Blart: Mall Cop.

Here’s the part where we could just walk you through the details to make it easy for you, but knowledge is power, and power is something you’ll need when you have a 238,000-mile old M42-powered BMW.

Step 2.0: The Basics

The M42 tachometer is aesthetically analog, but is technically digital. It receives a digital signal that gets translated and represented by a sweeping needle across a handsome 6200 RPM redline face. That signal comes in a pulse directly from the computer. That pulse is a beat of 5 volts so-many times per second (where in the off-beat it sends nothing, like turning a light bulb on and off). That beat of so-many pulses-per-second is the hertz frequency or just hertz. So if the computer is sending 5v pulses 20 times per-second, that’s a 20 hz frequency. In the case of the M42 owner specifically, those 20 count, 5v pulses-per-second, represent 800-900 revolutions of the engine per minute.

Step 2.1: All the Right Signal

Now that you’re a little more knowledgeable, it’s time to test that theory on some of the wiring behind the cluster to confirm which wire you’re going to circumcise for the good of your new tachometer signal input. Remove the blue connector and disassemble it as shown in the pictures. Since we’ve already installed ours, you should be able to tell that the black wire is going to be the one sending that 5v, 20hz signal from the computer. Start your engine so you have a frequency to read and place the setting dial of your multimeter in the “Hz” position. With your black wire still attached to the blue connector, you should be able to stab the red lead of your multimeter down into the top of the harness and hopefully contact the bare metal of the wire, and complete the circuit by attaching the black lead to any metal that is attached to the frame of the car. Grounding circuits out to the frame is a concept we won’t go into here because we have to get back to the Planet of the Apes marathon and there simply isn’t time. If at idle, you see “.02 khz” (move the decimal over a few spaces and you’ve got 20 hz) come across the screen then by Jove, you’ve done it! Splice into the black wire and lead your new wire away from the cluster to a location that will let you hook it up to your new tach. Our old tach no longer worked, so we opted to cut it out completely before re-routing it to the top corner of the dashboard on the driver’s side. Turn the engine off for these next steps or you’ll risk turning components of your new tachometer into tiny mushroom clouds.

Step 2.2: POWER!

With the hard part over, and depending on the state of things in your car, you are now tasked with the trial of finding a way to power the damned thing. With most of our HVAC control and radio missing, we had a treasure trove of wires to choose from to give life to the tachometer. Specifically, one that would gain power when we turned the ignition to ON and would invariably lose power when we turned the car off. We determined that by testing the voltages of wires as we turned the ignition ON and OFF. A tedious process, but an effective one. An easier option would have been to defer to a repair manual with an updated wiring diagram, finding a circuit that met our needs, and confirming with our multimeter. Run that power line from its source to your digital tachometer and move on to the next step.

Step 2.3: Don’t forget the little people – Staying Grounded

Remember when we said we didn’t have time to go into series circuitry? We still don’t have the time. Battle for the Planet of the Apes just started and we’ve already missed the crash landing of the spaceship into the Forbidden Zone and we don’t want to miss Taylor’s first meeting with Nova. Oh, Nova. But we will tell you that it’s not like a battery. You don’t have to route the ground cable back to the battery, it can simply be grounded to a nearby bolt, as long as that bolt has an all-metal path back to the frame.

We’ve learned to always anticipate that things will be removed for maintenance or upgrade, so instead of crimping or soldering the tachometer directly to our newfound power, ground, and signal wires, we snapped them together using parts from the same connector kit we used to adapt the oxygen sensor in our exhaust manifold blog entry from last week.

If you haven’t already, go ahead and plug everything in and give it a test! If you see numbers that make more sense than the timeline of the five original Planet of the Apes movies, than you’re now basically an electrician. Go out into the world and remember that it’s not the voltage that’ll kill you, it’s the amperage. Luckily for us, our Hitachi Magic Wand only pulls about 1.5 amps at the most. Don’t ask us how we found that out.

Now get out there and use that new digital tachometer for good by racing your E30!

Exhausting – If It Ain’t Broke, Break It: How to Replace a Broken Exhaust Manifold with an even Broken-er One (Part 1)

Photo Courtesy of Duncan Millar

Countless comments and posts, in countless forums, reiterate relentlessly that the M42 exhaust manifold (on some accounts, to have been sketched by Da Vinci in his Italian artisanal workshop alongside drawings of the Vitruvian Man and the ornithopter flying machine), is more than perfect in its functions of rate and flow. But this isn’t a perfect car, and we’re not perfect people, but the following analogy will be; Da Vinci’s flying machine likely never flew, and neither will we! Wait…

Step 1: Target Acquisition

Because we’re as committed as is reasonable to reducing waste, we acquired an exhaust manifold in a parts lot after convincing ourselves that the crack in the old one that we welded shut, will likely crack open again anyway, and thus warranting replacement. We’ll do our local metal scrap guy a solid and leave the old one at the curb instead of throwing it in the recycling bin. We paid $100 for a used fuel tank, spare M42 ECU and the titular exhaust manifold from a guy on Craigslist after following him from his college dorm apartment to a barn in the sticks, disregarding every thing we learned in every true crime podcast we’ve ever listened to about not going to a second location. The deal was too good to pass up obviously.

If you want to make future removal of post-manifold exhaust bits easier, weld on a flange. We found this one for $25-shipped on FB Marketplace and you’ll see how we affix it properly later on after a few more riveting blocks of images and text.

Step 2: Swinging – Getting that lower control arm out of your face.

Make the entire process easier on yourself by in-order unbolting the lower control arm bushing brackets (also known by fuckboys as lollipops), anti-roll bar endlinks, and anti-roll bar bracket on the exhaust manifold side of the car. This will let you swing it away from the car so that there won’t be as much banging around as when you were smashing around blindly in the dark for that condom your dad gave you a year ago after you finally moved out.

We removed the entire 22mm ST anti-roll bar to touch it up in a few spots where rust has started to develop. Because it’s made of a spring steel, rusty spots will exacerbate a decline into un-spring-steel-like qualities. This was also a lesson in proper preventive care because one of the few things we did right in the early years of building this car was using a proper silicone grease inside the anti-roll bar bushings. While anti-seize is an alternative we used in other areas of the car, it would’ve been detrimental here. Most off-the-shelf anti-seize products eventually dry out by design, leaving a powdery barrier between metals, but, would have been abrasive to the painted surface of the bar, eventually leading to rust. We’re also going to recondition the fasteners, washers, spacers, and brackets before we re-install it all later.

Step 3: Manifold Removal – The only danger to it, was us.

Removal, surprisingly, was the easiest part. While it can be done with a simple combination of a 3/8″ ratchet, 11mm deepwell socket, and a short-ish extension, you’ll save yourself a sore chest by using some sort of right-angle device. We used one that chucks right into the 1/4″ drive of our knuckle-savior impact gun. That and a 6″ magnetic bit holder placed betwixt the gun and the right-angle attachment (not pictured), gave us all the access we needed to reach every nut without having to switch back to simple primitive, proletariat hand tools. Seizing the means of production doesn’t imply that we can’t use power tools. An air-powered ratchet is a cheap alternative if you have a tank and air hose available.

In our case, this manifold had been removed and retrofitted with a new flange once before, so your disassembly process after the 4-to-2 collector might be different, but moving the suspension components out of the way will still be necessary to a hassle-free extraction of the manifold itself. Once we had all of the fasteners removed, we unbolted it from the aforementioned flange, and snaked it out like a toilet rooter from a clogged septic tank.

Recommendation: You’ll find that the fasteners will come out as either the nut alone or the nut and stud together. If both come out, watch this surprisingly short (50 seconds) and effective video on how to remove the stuck nut so that you can re-install the studs and use them as guides during the new manifold’s installation.

Step 4: New Manifold Preparation

Apologies in advance, but this process will be a little pacific to our situation. As in, the wrong side of the ocean. This was our second time dealing with an incorrect manifold, both having been built for a right-hand driven car, and we weren’t ready to fuss about the time and money required to tool-up a new one. The original manifold’s third cylinder tubing, ( a manifold which we will euphemistically refer to as “eBay sourced”) didn’t clear the motor-mount by any reasonable stretch of the imagination and for lack of material and welding skill, had to be replaced.

We got lucky and found one that was known to be persuaded with minimal percussive maintenance, so we glad-handed the old one off to some sucker for 20 dollar-menu burgers, and got to work dinging the new one up (with a combination of propane heat and a claw hammer) and welding on the appropriate accouterments. Because this one was still more than a little wrong we had to open up the bolt holes on the base plate to help align it, and weld a new M18x1.5 02 sensor bung to a mirrored position near the end of the manifold since it was making kissey faces with the floorpan of the passenger-side of the cabin. After that, we cut down the flange to the necked-down smaller diameter and welded it to the end of the manifold. We accidentally used an E71TGS instead of our stainless flux core wire so we’ll have to keep an eye out for premature corrosion since there’s no chromium in the weld to help protect against it.

Next week, check back in for the thrilling conclusion, where we deliberately post pictures in conjunction with textual descriptions of all the ways this process went wrong and how we eventually struggled together as a crew to pay our copay for group therapy in the aftermath.

Better on Vinyl – How to Apply a Windshield Banner

We have many fantasies. Most, if not all of them, could be shared with you here, but they would take away from the focus of this article. We’ll save those for our other blog, “What Macaroni Shapes are Best When Bathing in Tubs Full of Classic Italian Pasta Dishes?”

Today’s non-carbohydrate fantasy involves the awakening of something inside our childhood spirits. The dreams of those 11-year-olds, sat in front of standard definition televisions, fighting for their lives on that final Gran Turismo Super License test, have come to life. We are adults now, with wallets and eBay accounts. We now have a vinyl Gran Turismo windshield banner! Life is now the realest driving simulator!

All the “greats” have and had them. The words adorn instantly recognizable cars and events like the Pikes Peak International Hill Climb and the Nissan GTR Nismo GT3. Now, finally, it graces another legend in the motorsport community; our 1991 M42-powered BMW 318i!

Tooling is pretty light on this one. Especially compared to what we needed to install the flux capacitor. We’ll go over the tools you’ll need from left to right and then up top.

1. We had a small felt lined squeegee left over from a long-ago attempt to recreate a Marlboro theme on our hood, but you can just use a credit card. If you don’t have one of those, use your favorite adult video store loyalty rewards card. It will likely work much better because the felt lining wasn’t as aggressive on the bubbles as we’d have liked.

2. We used an old putty scraper to remove a sun-faded car class sticker from an event we ran at the Autobahn Country Club over the summer. This is another tool that could be successfully substituted with your adult video store loyalty rewards card.

3. In your mind’s eye, picture a can of brake cleaner or Goo-Gone next, to help you get all of the left-over sticky residue free of the glass.

4. (Imagination time again) Painter’s tape will help you keep everything in place while you line up the banner.

5. Use a smaller blade like ours if you can because cutting away the excess is going to need a precise hand, unencumbered by something bulky like a carpet cutter.

6. Use the microfiber and towels to clean the surface area that the banner will be affixed to.

Scrape the Pain Away

Cleaning the windshield is likely going to be the easiest part, but arguably the most important. Bubbles can form around debris stuck underneath after a time, even if you manage to completely squeegee them all away initially. It’s the simplest part of the job to get right, and you wouldn’t want your mother to be disappointed in you again, would you? Especially after that stunt you pulled at your high school graduation?

If you have something as dreaded as what was nothing more than a package label stuck to your windshield, scrape as much away as possible with something that won’t scratch the glass beneath it. Use some brake cleaner to apply a fatality to the remaining goo.

Now that you have a flawless windshield, line up your decal as best you can. We used the bottom seal of the windshield as a reference by making a mark at its center (green squares in the picture below) with a permanent marker. We found the center of our banner and matched it with the centerline mark (green) as best we could. Then from either side of the banner (upper yellow marks), we measured from its bottom to the bottom seal of the windshield (lower yellow marks) to make sure there were even distances. Throughout, we used some painter’s tape to temporarily hold the banner in place as we moved it around.

This is the tricky part. With the banner held in place by the painter’s tape, pick a side of the car, and as best you can, with a partner, pull the backing away a few inches and start applying the banner. Once you make the initial contact, start squeegeeing. Squeegee in the same direction as you are applying the banner. Get most of it laid down with this method and then worry about squeegeeing the edges. Don’t push too hard into the corners because you might cut into the vinyl. To make that step easier, cut away the excess, but leave yourself about two inches to grab at. Gently, (petting-a-kitten gently and not lock-the-door-and-mute-the-sound gently) pull that two inches up at a 90 degree angle to the glass as you push the vinyl into the corners with your edge.

Once you feel satisfied you have a fairly bubble-free and cornered banner, grab that small cutter. We recommend that you do this in two or three evolutions. Cut away 90% of the excess in a slow and steady pass. Be careful not to put too much weight on the windshield and bust it because you’re too focused on edging. If you see what we did there, go ahead and pat yourself on the back. In your second or third pass, cut away the excess right at the intersection of the seal and the glass. That should leave you with an aesthetically and nostalgically pleasant vinyl banner!

Go out and race that E30 already!
