94 inch circumference Hoosier tires.

I do occasionally, 92.5" to 94" Hoosiers. About 150 RPM higher with the shorter tires.

Just looking to see how close theory comes to actual measured results.

► 9250 RPM * (94 / 92.5) = 9400 RPM

I have a LT1 car. When I originally built it I thought I wanted the biggest tire I could fit. So I put the 94” on it. I’ve since been told I should have the 92.5” with my 4.88 rear gear. So I’m switching.
