You think with adding 3.73's, boring 30 over, new pistons, subframe connectors and weight reduction by way of seats, rear seats, aluminum driveshaft, ceramic shorty headers, enlarged throttle body, and ported lower with tune, I'm only going to pick up 0.4?

Heads and intake are where you start to see real gains. New pistons (unless you bumped compression significantly) & 6 cubic inches won't gain you too much.

Especially with 18 inch wheels and street tires, I don't see you getting into the 12's real easy.

Your heads are not bad, being GT40's, but I'd say a 13.3 now as well, b/c when you said fully ported and polished I thought you meant heads and intake for some reason, GT40s ported are no slouches...

I'll go with 13.2-13.4. Like mentioned above, being bored .030 over and new pistons will not add anything unless you upped the compression. Taking weight out of the rear of the car is only going to make your traction worse on those 18s. I think the biggest gain will come from the 3.73s. What was your 60ft time and mph on the 13.9?

Well if people tell you 12s and you go 13.5 your going to be mad, whereas if we say 13.5 and you go 12s you will be happy as can be. It "could" run into the 12s with ease, it also could go high 13s...

Yup, that's why i said 13.5.
Sure the car will have more potential than that.
But you asked what we thought you would run, and didn't mention having drag radials.
With 3.73's and standard street tires, you may even go slower.
What you really should of done is give us your mph, and ask what we thought your new mph would be, which will probably be up 4-5 mph.

You guys are nuts. 18" wheels and Corbea ?sp? seats should peel at least a second off.
