Hoosier C30 Compound

[MRE 7171]

If the Hoosier 18213 is 94" circ. and this tire is for factory stock, what rear gear do they run and how much horsepower are those cars

I don't know the power they make, but it's more than mine. This is just a small tire bracket car set-up to run mid 8s. I'm only legal to run 8.50 & the biggest problem is I'm not legal to run 150 mph +, yet.

Below is/was my gearing. I have no idea on the HP, it hasn't been on the dyno.

We part throttled to the 1/4 mile & went 8.8x @ 143 mph. That's .1 quicker than our best at both distances & that was getting out of the throttle/part throttle.

I changed the rear gear from a 3.89 ratio to a 3.55 to knock some rpm out of the finish line. I guess it liked the change. The converter flash stall raised from a little over 5,500 rpm to a little over 5,800. The shift drop went from 1,000 rpm to 600 rpm drop. Pretty much what Kevin @ Hughes Transmission predicted.
