heading to teh 1/4 strip this weekend.
i'm taking the ole 91 GXL up to our 1/4 mile drag strip friday and i was just wondering what i should run. i think we're gonna run a straight pipe from the exhaust manifold out the back of the car. that would make my mods just straight 2.5" exhaust with no muffler, intake, aux ports open fully at 4k and VDI works perfect, FD wheels with 225 kumho 711's. i'll be taking out my passenger seat, spare, jack, subs, rear carpet, etc for my runs when we get to the track.
i would really like to see a 15.99, but i have a feeling its gonna be some high 16's low 17's
what do you S5 NA guys on here run with intake and full exhaust with 6pi and VDI working?

well, up here at 1 mile high, with a crappy launch (2.5 sec 60') I ran a 17.7. An s5 GXL ran a 19.0, then a 19.9, but he REALLY sucked.
Don't be surprised if you run a **** time. If you've never done it before you won't run very well.

Yo,
I've run low 16's, then high 15's. For your car, depending on your launch...I'll say 16.10 @ 88.7mph.
How's that for a guess? *grin*
My car doesn't have working 6 ports, so you should be able to get a good launch. It's all in the launch!
Good luck!

well, it looks like the quarter mile thing is gonna have to be pushed back a couple weekends. they are having some bigass domestic sanctioned event all weekend at the 1/4 track so we're goin to the 1/8 track (its right down the road)
any guesses as to my 1/8th time with a full intake/straight exhaust/working 6pi and VDI?

i have been under the impression that slipping the clutch from about 6000-6500 would be the best way to launch, but hell. thats a clutch's worst nightmare. i usually just dump the clutch at 6000 and it doesnt do TOO bad...
whats a "good" launch with an NA on street tires?
PS, i have FD wheels with some nice new 225/50 tires in the back.

I have to get back to the track soon, but I ran 16.70@84 something with no 6pi sleeves, screwed up afm, and TPS with a straight pipe. Now I have slightly lower profile tires, short shifter, header/presilencer, and the 6pi sleeves in and working properly. I would be happy to get into the 15's.
