Re: Flash944's attack on a 50 MPG beater
My times at the 1/8th mile drag strip about half an hour from where I live.
Reaction .5852 (0.5 is perfect at this strip)
60' 2.5007
330' 7.1770
1/8th ET 11.0562
1/8th MPH 62.71
The setup:
Put my set of E30 wheels on there because they were the ones that are the most balanced of all the sets I own. I hadn't had them on a car yet, and they look pretty decent if you ask me.
Carpet OUT. Started cleaning the rest of the interior out. I'm really thinking about getting rid of the sound deadening as well. Less weight = better economy. Noise doesn't bother me, I build mean audio systems.
And yes the drivers side axle did get changed before I went. The CV joint was just a little dry...
I got to do 5 runs, and I tried preloading the axles on the last two. Doesn't seem that hard, and it sure feels alot better on the car. I'm just curious how well my 40 dollar stock used clutch and pressure plate will hold up when doing that a lot. Those wheels and tires have plenty of rubber on them, and I didn't even bother airing them down. But it was interesting for the first run, I just chirped the tires past the water box to get the water off, then dropped the clutch from redline. THE CAR DIDN'T BREAK TRACTION. I was like wtf, bogged like hell out of the hole. The rest of the time, I made sure I heated the 620 treadwears up enough to actually slip some off the line.
My best time with this motor and a P20/B000 in a stock CX chassis was 10.1. So basically this transmission and a little extra weight costs me a second in the 1/8th.
This transmission makes some interesting noises. Clutch in, no noise, neutral and clutch out, very faint whining/grinding sound. In first and second, it whines worse under engine braking. I'm talking a noticible whine, even over the muffler-less exhaust under power. Nothing feels bad, the car shifts just fine. Doesn't make the noise nearly as bad in higher gears. I don't know what it is, but for now I'm rolling with it. It didn't break doing redline drops, it should be okay long enough to do some MPG testing.

Re: Flash944's attack on a 50 MPG beater
There was a turbo Z6 eg hatch there who broke an axle on his first pass, then made 2 runs, both slower than mine. Supposedly eagle h-beams + vitaras and he did have a 63 trim on there, but the dude didn't preload, and he just straight up sucked at driving. Street tires not aired down, like 17" rotas, and when he spun in first, dude never let off to regain traction. i don't have a ton of seat time at the track, but damn, he needed help.
Also was a h22 swapped eg hatch, his best run I saw was a 9.8. I wasn't that far off his time with the other tranny and a stock Z6 with bald all seasons. I can't wait to get something turboed and maybe some slicks.

Re: Flash944's attack on a 50 MPG beater
*UPDATE*
It's been along time comming, but the bitch is turboed. I'll get pictures soon and I'm doing a lot of reading so I can tune this thing.
Setup:
stock z6 with stock cx tranny
14b turbo with stock O2 housing
pop rivet oil restrictor
A/C and P/S kept with a log manifold
DSM 450s
PLX M-300 wideband Crome free with freelog
straight piped 2.5" exhaust
2.5" charge pipes
CDM special intercooler
DSM 1g bov
haven't come up with a solution for PCV system yet other than vented to atmosphere
currently on a basemap that I made. Idles fine but I'm not sure I'm going about it the right way in Crome. I have a bunch of questions that I'm gonna have to search for or get help from you guys with. I'm trying to figure out what spark plugs I should run, and I'm researching proper a/f ratios that I should be shooting for

also when engine braking using first or second it sounds a whole lot like reverse does with the gear whine.

wrx's are notorious for this, and mine does it, but with no pattern. some days it does, some days it doesnt

Re: Flash944's attack on a 50 MPG beater
well I know that I have some bosch 2+ somethingorotherbullshit spark plugs in the car now. I've found a set of NGK zfr5j 11s layin around so I think I'm going to clean them up with some sand paper and gap them to 0.044" and throw them in to tune with. I couldn't find anything colder than a 11 from NGK that would fit, anyone have any recommendations?
