Okay you guys, this is getting over my head again. On the site I sent it said that my tire size equates to 26.5" tall. They also mention that the tire will grow in circumference as the speed increases, but this is supposedly incorporated into the equation.

If I enter in 26.5 in the charts of most of the different sites it comes out almost exactly the same at 2480 RPM at 70 MPH. Let me know if you find something else and thanks for all your help.

NOW..... Lets get more of our cars at the drag strip this year and see what kind of fun we can have. The cars don't have to be fast to have a blast. My car won't come close to the times and speeds that are listed. I would be happy if it ran in the 12's at around 105MPH. This would be a great trip for our club to go to the drag strip!!!!!!!!!!!
