My question is, If I went to a 28" tire, what would the 60ft change and how would it affect the mph at the stripe.
Here is an example, put your rpm in and recalculate. This assumes that your mph doesn't change.
RPM2 = RPM1 x 29.5/28 6321 = 6000 x 29.5/28
If your combo likes the change, it might improve mph maybe 0.5. If it runs out of breath, it could reduce mph by more than 2.0 If everything works, I think it should improve the sixty foot by maybe 0.03
