I've run a best of 13.48 with a chip, 90mm mass air, on f1's with 2.0 60 ft's with 65 degrees. We're 1700 ft above sea level here. What do ya think, what kind of improvements have you guys seen with a 4 lbr... Thanks


changed 12.48 to 13.48

 

I don't understand your post...did you mean 13.48 ?

I got into the high 12s with a 3 lber.

If you meant that you ran a 13.48 then a 4# should get you into the 12's pretty well....as long as you can hook it up.

I still can't, no TRACTION at milan even with my hoosiers,might have not had enough air in them

I was hot lapping 12.5's with a 4# lower. But the air was flawless for drag racing that day.

Yes a 4# lower will easily get you into the 12's.........just have to wait for the fall to see the really good numbers.
