hurry up.
i want a lane on the 28th

I'm trying, but my tuner won't be back in the shop 'till the 23rd so it's gonna be close.

I did, but I sold it. I didn't wanna cut up the harness.

I could have gotten the stuff to make a pig tail harness to plug into the stock harness and then into the 90:dontknow:

A few years ago, my car with a very similar combo, except that I had iron gt40 heads, and a tubular gt40 intake went mid-12s to low 12s with a 5 speed. Then I had it tuned for race gas and turned up the boost. The car then went high 11s.

The heads (they are still stock, aren't they?) and intake are going to be the big restriction on this car. Not to mention that it is a GT (like mine), which means that it is a bit heavier than the LX's, especially the notches. Until the car goes on a diet, I call mid to high-12s@110-112mph.

Mid to low 12's is good for a S-trim,stock 5.0 and an Auto.

 

[TwilightBlu92]

Is this with the stock pulley or the smaller one?

This is right on the money imo, back in they day a guy I knew had a mostly stock gt with a tb, rockers, exhaust and a vortech pullied for 10psi. This car went 12.80's around 110 on a street tire, it was also a 5 speed car.

That's cool, i'm hoping my auto will have the advantage in this situation. I know the secrets to shifting it , plus I cut really good lights.
