1/4m time

[WonIt]

sup ppl ,,, im goin racing this weekend,kinda trying to get a round about time yall think my car SHOULD run

only mods are:

BIC ddp,BIC test pipe,and 2 3/4" pipe from there!!

and im gonna crank the boost up to about 10psi

i know alot depends on te driver,but like i said whats a roundabout quater mile time with that little done??

oh running on 16" street tires,and auto tranny

 

[GotBoost?]

Idk, low 16's, mid 15's? And what have you done to prep the car, so stuff won't break on your racing debut?

It should run very well. The exhaust greatly improves engine VE, and the extra boost will be even more benificial with the VE improvement.

i was thinking somthing like a high 14 , a guy i met the other nite said he ran a 15.3 with just a exhaust system on stock boost (7psi)



but im wonderin do these cars need a muffler for the backpressure?? or should i have more HP with the free flowing exhaust?

 

[WonIt]

any others with input??

The turbo proves enough backpressure, you basically want as free as you can get after the turbo. Also, why not do full 3 inch exhaust? Why do you have it go down to 2 3/4? That'll make a difference.

I see a 14.9 in your near future. It will probably depend on the weather also. Maybe this fall you will run a little better. Go to the track now,and learn what rmps your car likes to lauch from. Every time you go down the track, it will help you with later races. Good luck and have fun. Don't forget to post up your numbers here to keep us informed.................lol

on street tires.. id say mid 15.. depends on climate though..

 

[89Turbo]

check my sig, that is bouncing off my rev limiter in first though so it hinders it a bit

 

[SupraDreamPDR]

high 14s. i ran the same with exhaust and stock boost.

 

[WonIt]

The only reason i have it going into a 2 3/4" pipe is becouse it was on the car when i got it,just havent changed it yet..shouldnt hinder the performance ,atleast i wouldnt think since it doesnt have a cat or a muffler... would 1/4" make that much of a difference???


only a few days left til i find out what she'll do...hopefully i dont blow it up,but i dont think i will,ive ran her hard a few times,and open it up atleast once a day to keep the exhaust nice : )

 

[drjonez]

heh. a 1/4m race should be fairly quick....

seriously, while estimating is all good and well, the best thing to do is go find out. realize that drag racing isn't nearly as easy as it seems to be....have fun and learn!

if you can drive high 13 to 14.0... fwiw 10 psi (falling to 7) stock exhaust/intake i went 14.33 at 95

I'm with him, I only had an mbc that hit 12psi then set back to stock boost and I trapped 94mph. With the 2.3 60ft' I managed a 14.7 et.
