Ran a 15.4 in a 95 Grand Prix 3100

[blackbombshell95]

I hit the nitrous on first gear around 3200 rpms and my trans got stuck on the 1-2 shift which scared the shit out of me cause i was probably running lean for that split second. So that probably took maybe a tenth off. Who really knows. I held the nitrous for the entire 1/4

Mods:
No port work/no computer
62mm t-body
short ram intake
FFP UD pulley
FFP Dog bones
2.5 catback
plugs/wires
92oct w/oct booster
55hp shot nitrous


My best time without nitrous is a 16.2 @ 85mph last year.

Wow you ran without a computer? Did you use a carb? j/kl
You weigh more than me, as only with a dynomax ultra flo and stereo I did a 16.0 way back in the day. I want to do full exhaust someday, and really want headers, but other than that my 3100 is going to stay until it blows up. I am putting on ported 3400/3500 intakes though, so hopefully I'll get a decent boost from that "bolt on". Curious as to what I'd run after that hmm. I might get a UDP whenever budget allows. Too bad the closest track is bulldozed and apartments there now.

Any idea what your weight is? How many miles you got?

My hood ways a ton with that scoop molded in. Probably 3600 plus me which I am 225 lbs at 6'4.
And it has 91k on the clock. I've been using mobil 1 full synthetic since i got the car at 62k miles.

Also it is hard to get good times at that track. I always run 2 tenths of a second faster when I race at bremerton raceways. That 15.4 run was at Pacific Raceways. The main difference is that the gates open at bremerton at 8:00 a.m. when it is nice and cold. And Pacific raceways opens at 4:00 p.m. Plus it was a 75 degree day when I got the 15.4 run.

nice run, i used to have a similar setup as you when i had my 3100. i ran a 14.45 with a 75 shot and almost the same everything else. Now with the 3400 it runs consistent 14.10's. I think when you get those headers installed you should see even more with the nitrous

How is it possible u ran a 14.45 with a 75 shot? Did you run it all the way through first gear starting at 3k rpms until the 1/4 was finished?
