Guesses to power and quarter-mile times on a S2 3800SC/4T65 combo with these simple mods:

VS Cam
3.4 Pulley
Sinister Tune


How much smaller (average, i know every car is different) of a pulley can you run than a 3.4 with that cam?

Maybe a very low 13 second or high 12 and not a lot smaller pulley with just the VS cam unless you are going with an intercooler or maybe a good in car tune and scan. Dan

I have about the same setup as you until I changed to E85 this spring. 12.5 at 105 is about what you will run.

I went 12.75 @ 107mph with that exact setup. I had a 60ft of 1.77 as well. If you can get a good launch in you will hit 12's all day. I had stock gears in the transmission too.
