9's with nitrous?
 

Basically my quest is to run as close to the 9's as possible.
What i got:

71 Vega GT
LS2
Patriot 5.3 heads
Speed inc SI5 cam(231/237 589/595)
LS2 intake w/fast 90 TB
LT's with dual 3''

T56-rebuilds.com rebuild
spec stage 3+

12 bolt
3.73's
Richmond trutrac
spohn UCA + LCA's

The car weighs 2651lbs with a full tank of fuel(16gal) and i plan on knocking out almost 100lbs off the car so with me in it, i should be around 2700lbs.

I have ran 12.52@116 with a completely stock ls1 in the car and now i have approx 100whp(has not been dyno'ed yet)i obviously plan on running some slicks ect.

I know my cam and heads setup isnt the best but its what i have to work with right now and im thinking if i am around 430-440whp right now with 150-175 shot i should be close to the 600 range(will be tuned by vette doctors) a local guy sprayed a TNT kit with a 200 shot and put down 580hp 560tq(i dont know why the torque is lower? slipping clutch?)

im estimating that i could have ran a 12.1-12.2 area with the stock ls1. then the general rule of thumb with a 100hp more(H/C LS2) i could be around 11.1 and another 150 shot being close to the 9's but thats all easy to say, factors as in hooking up ect with play a part. I need some advice!

at 600 rwhp and 2700 pounds you should be in the 9.6-9.7 range and probably flirting with a 140 mph. since you have a six speed maybe bring it back up to 9.7-9.8

high 9's for sure

So as long as i can hook i should have no problem? would i still be fairly safe with a 175 shot or is 150 the threshold of basically being fairly safe with a good tune. it will probably not be used very much, just occasionally on weekends when i try to go out and embarass my uncle. :)

I'm auto, but I went 10.9 NA and 10.doh on a 150 shot. I had low bottle pressure might have been 9.9@134 since it was 133.9mph on that pass. I think if you can run 11.1 you might get there but if you are mid 11's on motor you will need more nitrous

Hey john, what is the raceweight on your car?
