Ok my best is in the sig. Now, what do you think i could run if i upgrade to a ported FAST 92/92 (i have stock ls1 intake now), asp 25% Ud pulley, and take out the spare tire/jack (37lbs)?

And for anyone that knows anything more about compression, what would you guess I could run if i added everything above, and then milled the heads to bring me to 11.3 : 1 compression as opposed to the stock 10.1 : 1?

Sorry for another one of these threads BTW, but at least im not going from stock and listing a million mods for u to guess on.

 

Don't know for sure but that intake is killing you. What heads are you using? Intake, even an LS6 would be huge increase, unless your heads are the next bottleneck. Fix that and look out. Hope you have a strong rear. lol

 

I'd say at least 11.50's. work on the 60' and you'll get 11.20's-11.30's

 

takes more power to go faster once you start goin that fast im assuming your goin 770s 780s in the 1/8th???id say all that might get you 11.70s 1180s ....

 

What about maximizing the suspension first and then spending more on the heads instead of the intake? Ls6 intake with really good set of heads. When I go forged 382 w/ my LS6 I'm going with the new ls1 warhawks.

 

According to my calculations a mid 11 sec slip is quite achievable.....
Depending on gearing/stall/tires/suspension you can get anywhere from a low-mid 11
to a 12 sec slip.......

 

Did you he see that he has a cam already? going from a stock ls1 intake to a ported 92 and a nice bump in compression are going to wake that car up big time. Along with the pulley, I'll say he'll trap 118-119 in the same weather as the 12.0 run. Its up to him setting up the suspension as to what hes going to ET
