Those are some pretty good times considering the conditions.
You should have got some 3.90 gears when got the clutch and flywheel done. With M12 transmission you end up almost at the redline in 4th at the end of the strip. Then again you would have some traction problems on street tires because they make a huge difference.
My uncle just dynoed at 397rwhp with full bolt-ons and a custom tune in his Z06. What are you at right now?
