WOW what can I do
 

I just finished Installing a nos drykit 75 shot and have been tuning it my best time before was a mid 13 around 13.6 at 103mph car weighed 3430 wet this is with a bad 2.1 60 foot time on very bald street tires. When I hit the N20 It screams now. what do you guys think I will hit!!!!! I must get into the 12s I have added a CAI and adj FPR on top of the former combo!:cool:

With slicks I think you'll pull mid 12's. On street tires you might not do too much better than your 13.6, probably able to get low 13's, depending on traction w/ the extra hp.

My first GT with an AOD in it went from running 9.91 in the 1/8th to low 9.20's with a 75 shot on radials. I put at set of McCreary's on it and dropped to 8.70's on the 75 shot. I went to a 150 shot and dropped to 8.20's. The car had a K&N, electric fan, and MSD ignition for the nitrous as the only mods to it.

I know because the car was and AOD was the reason it ran no better as far as ET in the 1/8th, my car just wouldn't come out of the hole. But I always remember having a mph as high as the stick guys. If I can dropped 7 tenths in the 1/8 on radials, I see no reason your car want drop the 7 tenths it would take to get you in the 12's in the 1/4.
