Product Description

RJ Transmission, Rear Gear, Tire Ratios vs. Air Correction Factor Calculator

This software is used by top crew chiefs to help determine changes needed to be made from track to track and changing weather conditions. All you have to do is plug in the information from one of your existing runs (air correction factor, tire circumference, rear-end and transmission ratios) and changes you wish to run and it will suggest to you what transmission ratios to use.

Lets say you went out and made a good baseline run, and now you want to change your rear gear from a 5.29 to a 5.25, and run a different set of tires with a slightly shorter rollout. Also at the same time suppose the temperature cooled off and the air correction factor went from 1.065 to a 1.057. The calculator will take all of your inputs and calculate transmission ratios equivalent to your baseline setup.

We use this software every run to tune our car and adapt to the changing conditions from track to track.

The calculator uses the following user information to help determine changes needed to me made to the gearing of your car:
• Transmission ratios up to 5 gears.
• Rear-end ratios
• Tire circumference
• Air correction factor

Microsoft Excel software required for use of this calculator program.

All software is non-returnable and non-refundable.
