Aero is definitely on my list to do. Chassis, brakes, suspension, wheels and tires are all sorted. Need to do some engine work (more mid-range top end power) THEN aero.

Glad to see you out there enjoying the car and all your hard work! Me and a couple friends are doing an HPDE event in May.

thanks!

the aero was actually pretty straightforward... the splitter just took time and remembering to continually pay attention. it also helped to have 3x ppl working on it at times -- lots of the **** work (aka cutting aluminum angle stock in to 5000 little brackets) was getting done while i was obsessing over the splitter w/a variety of levels and measuring devices. :)

When I built my splitter, I used a few sticks of 1/2" aluminum angle from Lowes, bent them into the shape I wanted and welded them together to have a single continuous piece. Using a shrinker stretcher would have probably been ideal but because the angle was so short, I just bent it in the vice and shrunk it manually. This makes it so the air damn can be removed and retain it's shape when I eventually destroy the splitter.

welp... that didn't last long. :(



one of our drivers barely got any sleep the night before and was totally out of it. she tried an inside pass @ T1 (sonoma, sketchy place to pass) 15m in to the race on sunday, got spooked, lifted at the apex and swerved... promptly spinning the car and hitting the wall. hard.

in fact, the impact was so hard that they stopped the race for 30m and the track had to use their largest forklift to get the k-rail back in place. later, when chatting w/jay lamm (head lemons honcho), he said that we have the unofficial record for most damage done TO a track... this all coming from a ~1800lb car. :(

the driver was completely unharmed, just a little sore and pretty shaken up. all of us should have realized that she wasn't alert enough to get in the car, but it was a pretty hectic morning and we were all tired and short on sleep... now we know the signs to look for!

we spent a bunch of time today looking over the car with some other racers and they all think that we can straighten the chassis and keep her alive. the suspension on the passenger side actually looks fine, and even though the car took one HELL of a hit, no liquids vacated their respective homes and the car fires right up! i'm a little concerned as there's a bunch of buckling/crumpling inside the car but we'll take it to a shop and get their opinion.

the plan here is to transplant all the go-fast bits in to another donor shell... i have a line on a 91 civic Si, and we're cruising craigslist as well. tbh, i hope we can find a CRX 'mechanics special'... i love these little cars!

also, if we can straighten this chassis, we'll rebuild it w/less cheaty parts and use it as a race rental!

it's sad to see 2 years of work balled up like this. the car was absolutely sorted, and probably some of the most fun i've ever had was working my way through traffic. :)

oh yeah, our little d15b2? i just remembered that i never posted the results... and they're mind-boggling: 100whp/88tq! this was at griffin motorwerke on their mustang dyno, and they swore up and down that it reads low... where the hell did those extra ponies come from!?!?!

engine mods: homemade icebox intake, Si MPFI/intake manifold, 3" cat-back exhaust. and yes, we were running the cat lol

magic. honda. engine.

anyways: we're hoping to get version two finished in time for the december race @ sonoma. crossing my fingers for a beater craigslist CRX! :D

well, that was fast: i just got off the phone w/my teammate and he bought a beat to hell 91 si w/a ZC engine swap!

i literally can't believe his luck on craigslist lol

i'll post some pics after it gets towed to my buddy's place.

Good cage, then! Time to buy the fabricator that built it a beer! Glad to hear the people are OK. Cars and armco can be fixed.

here's some video of me from the POV of the miata i was hunting dow
n:

i present myself, wait for it, and have a clean pass about a lap later. i end up pitting the next lap (~30m before the end of the race) coz one of our driver's side front wheel studs decided to give way and fall off w/a loud thunk entering T2. :(

That looks like a really fun track. It's cool to be able to watch your own car from someone else's POV. My buddy and I have that same footage during HPDE events.
sears point is my home track, and only 35 minutes away, door-to-paddock. i'm absolutely blessed... it's a small but world-class venue and i probably do ~5 events a year there. i've also attended NASCAR, historics, USTCC and other events as a spectator.

it's a better track than the nurburgring, and i don't say that lightly. :)

i was really happy when i found the footage from the miata's POV -- i totally remember chasing him down just before the stud popped off and me needing to pit. i'd just spend the previous 30m chasing down and passing that silver Z who passes the miata immediately after me... :)

here's some other in-car footage of me thrashing some other "crapheaps" around sonoma:

alright, quick update:

the new car was definitely maintained by monkeys and for some reason, parts of the unibody around the radiator were cut out. it definitely was in a crash at some point, but the car tracked straight during the test drive. if we're missing anything important up there we can almost certainly fab something (or cut it off of the wreck and weld it on).

here's an example of some fine craftmanship:


we've got most of the suspension bits from the wreck on to the new car, and once that's done (and we procure a seat w/the proper seatbelt receiver) we'll take it to get aligned and cross our fingers that nothing is bent.

since that ZC is of unknown vintage/condition/mileage, we're gonna pull that and rebuild it as a spare. we'll run the D15 initially.

after that: gut the interior, swap the gas tank, cage it and take it to a track day for shakedown.

after THAT: paint, fire suppression, whatever else we missed, and finally RACE. :)

btw, we're still building... and picked up another old crx racecar shell + a bunch of goodies. it's literally a game of tetris between zc-swaps, a variety of si transmissions and all the associated sundries. i'll get something posted in the next couple of months. :)

sadly no video, but today the grey ****heap drove under it's own power w/the orange car's engine/tranny, harness, and suspension! i got a few looks driving around berkeley for a couple of blocks, mostly because:

1) no doors
2) no hood
3) no plates
4) cage

there's a stutter on the throttle at low rpms, but other than that (and the obvious need for an alignment lol) everything seems good! more pics to come.

long time, no update... mostly because we spent april and half of may tracking down a misfire.

TL;DR: who-knows-how-many-years-ago, the original person who modified the loom for the mpfi upgrade used a wire that was corroded. it finally snapped (yep), which led to intermittent and confusing electrical readings on the fluke.



during this electrical nightmare, we also cut out more unused bits of the loom and wired in a switch panel. the piece of metal we mounted everything on came was an old aluminum server shelf. it's super light, sturdy and easy to work with!





you can buy these shelves new for less than $20, and i highly recommend them for **** like this: https://www.amazon.com/Cantilever-Server-Shelf-Mount-Aluminum/dp/B01HH6WN1I

it's still a bit of a rats nest, but it's getting a lot better. we still run all of our relays, which means we're double-fused on ignition, main power, 12v, etc... it's definitely an area where we debate the pros and cons of running everything on it's own fused circuit vs keeping the oem relays. decision TBD.

we finally finished stripping EVERYTHING off of the old shell, and made a few hundred $$$ by selling it to some folks who were planning on re-using the cage in a track (not race) car



and here she is, franken-rex v2... aligned, insured, registered and ready for some shakedown drives in the hills!


(not in shot: orange bumper)
