2004 GTO 1/4 mile guesses?

Recommended Posts

Just curious what you guys think this thing might run. Its a bone stock ls1 auto car. I have ran it before, it went 13.8 @ 101, BUT it was made on drag radials that were a good bit taller than stock and rubbed big time on the metal lip of the fender, destroying the radials after one pass (you could feel the car pulling to the right, so it had some drag to it)

Also latee found out the MAF was dirty causing the car to run lean and knock after 4200 rpm. Picked up 15 whp after correcting the issue.

Any guesses?

I'd guess if everything runs as it should and you have no real performance mods to the car, then I'd say you could run a 13.3 at ~106 MPH as is.

with the taller drag radial you change your aspect ratio which would slow ya down but, in long run help out. But, with the proper size ratio drag radial you should be able to exceed 110mph around 13.1. I have a calculator for that I'll find and post for you.
