What ET gains going from a 30.6 street tire to 28 slick?
I am going to the 1/4 mile this weekend and just wondering what I might run... My previous 1/8th mile run was 8.75@80mph on a 30.6 street tires... This weekend I will running a 28.0 slick. From my estimations a 8.75 1/8th time is roughly equal to 13.7-13.8 1/4... I am hoping the shorter tire will help me cut a 1.8-1.9 60ft and a 13.5ish 1/4... Do yall think that is possible? Remember this is with the 4.8......

I think it'll make a bigger difference than you're hoping. All else being equal I can see you running a low 13. Not only are you getting more traction, you'll have less rotating mass and also your effective gear ratio will be better.

It should show gains across the track once you find the right tire presser and launch technique.

Well I would still expect that will see a decent gain regardless because with the shorter tire you are effectively lowering your gear ratio which translates into more torque.
