    Low PSI slicks will get taller the faster they spin because of the G-forces involved so maybe that is the difference????

    yes i know but a 28" tall tire is still the same tire. with centrifigual force it would have to grow over 3"? not registering in my head i guess.

    I'm sure it could at the correct PSI and I have no idea what PSI Dan is running so can't be sure.

    it has more to do with the side wall of the slick then the psi since that is the part that will stretch and make the tire grow

    SonicVenum almost hit his rev limiter (set at 7000 rpm) while trapping 131.96 at a Sea Level Track.

    He was pretty informative when he raced, but then again, he was losing alot of air from the screwed rims he had.

    From the tires I ran, the combination of tire pressure and duration of the burnout effected my top rpm too.

    I think 4.10s are a little too much.

    I will go with 3.73 or 3.90's.

    Burntire, I just checked Speedworld's mph/rpm range calculator and it says that with a 28" tire and 4.10s, you should be running 132.1138211382114 at 6500 rpm. Of course, that's assuming you're in 4th gear.

    Hope this helps.
    '03 Cobra - Mildly modded. A work in progress. 12.566 @ 110.755, 1.89 60' on street tires
    '93 Notch - Looks faster than it is.
    '72 F100 4x4 - Dormant, for now.

    I added a ton of calculators to the site due to this question.
