Since no one in the 11secong loungs of 12 second lounge likes to comment on my post. I was wondering, and i have a pretty good idea, but just another oppinion, what my gains are going to be 1/4 and mph wize frrom going with my mods in the sig (stock ls1intake) to a PORTED Fast 92/92 combo, and 25%underdrive pulley.
And since this is external engine many might not have an educated guess, but after all that, if i milled my heads to bump up my compression to lets say 11.3:1 stock is 10.1:1, and had all the other stuff mentioned above what do you think i could run? I want race the LSX shootout at atco, and i wanto enter the 11.5 class. Let me know...

 

fast 90 and uderdrive pully isnt gonna get you from a 12.0 to a 11.5

 

if it were only that easy...

 

ported 92. and im saying with the milled heads and the over 1 point compression increase. And... 50 pounds lighter, and it shifts at 6400 now, and the peak h/p is 6600, so if i change that to 6800? then what?

ehh i know, im not tryin to be the guy thinkin my setup is the way too go and sayin im def gunna hit the number, i just rele want to get there. After that if all the **** doesnt get me there, then theres an electric water pump, and after that its heads.... witch is something im not ready for.
