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!

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
