Re: RPM ?
Go to TCIAUTO.Com On their web sight they have a section for Tech Center, Click on that and then go to technical resources. Then click on Racing calculators. You can figure any of the following 4 with 3 of the variables known.
Rear gear ratio Tire diameter Engine rpm Miles Per Hour. They have many useful calculators at the same place.

Re: RPM ?
This formula requires knowing trap speed - which like, if you know that you probably already know what the rpm was:
RPM= (MPH?Gear*Ratio?336) / Tire*Diameter |
