17's if you're lucky lol.

My chipped M20B27 ran a 16.7 lol

[e30trooper]

what are some turbo'd m20 or m50 times? wonder what my stock m10 would pull off haha 17's

[SamE30e]

I'm going to G-tech my car for a rough estimate tonight.

Might be within a second... or two of accuracy. lol

r/t does count for much anyway as it won't contribute to your time, it will only determine if you beat the other car/driver

Yeah a few of my friends quickly shot me down as well haha. It was just luck anyway...

I'm at the track now...


Vanos m50, 260, 3.73 LSD, v710's @ 17 psi, ~2700lbs


R/T .313
60. 2.216
1/8 9.48
mph 75.12
1/4 14.688

My best r/t was a .054 but I missed second :(

My last run, I ran with bald all seasons, wheel hopped the whole way through first, missed 2nd gear (twice), and still ran a 14.9 @ 95.

I'm happy overall. My m20 325is on Azenis only ran a 15.4 and that car was 300 lbs lighter at the time. So a full second quicker with the m50 and +300 lbs.

are any of you adjusting tire pressure to help with wheel spin/hop?

[SamE30e]

ya you will forsure if you are easy on the launch. I want to pick up a 4.10 lsd and ditch the 3.73.

I dunno, it just doesn't feel like a 14 second car, I mean i've been in low 14 second cars but they were FWD, maybe that's it.

We'll find out I guess.

best out of 3 runs.. i think i could break 8's

[416stroker]

Nice, I was hoping it'd dip into the 14's.

I have a Dinan chip and a 4.10 lsd.

Has anyone run a stock M50 non vanos?

ya I ran a 14.8 the only time I went with a stock n/v. It can do better it had a vacuum leak.

Ok just for a comparison, fishforlife (bimmerforums) in his LTW m3 ran an 12.236 @ 112.38.

But he has a little less weight then our e30's.

And a better suspension+tire setup up for launching his car. Plus he is an amazing driver.

That set-up is def. capable of 12s in my opinion. I just added the stage 2 kit to my s50 and it feels like a low 13, but it seems all of us with street tires have wheel spin issues. Im even running 205s. If I can get my falkens hot enough though they dont spin quite as much.

I concur! If e30lolz on BFC can run a 13.07 w/out the cam kit in his s52 e30 m3, then loonibab should be in the high 12s for sure with better tires and a more appropriate suspension!

After looking at all the numbers, I doubt I'll break 14s my first time, since I've never done a 1/4 mile on a real drag strip. I have traction issues already with the 3.46 in the streets, I can't imagine on the strip. I beat a lot of cars off roll, but I don't do much racing from a dig b/c I just sit and spin. What rpms is everyone launching at? I feel that I'd have to feather the gas and side step the clutch to really perfect my launch.

Nevertheless, I have some soft springs I can use in the rear to help me squat better. I think my KDWs have enough tread life left on them to hook up pretty well. My rear end is too stif for launching right now, The poly subframe and RTA bushings, along with my spring rate and shocks wil probably keep me spinning through third. Plus I know I'm not any better of a driver compared to some of you...

I remember my car weight transferred and launched much better with the eibachs and stock bushings....hmmm well maybe I can get ahold of some used drag radials and hit the strip soon!
