Location: Hayward, Calif | Hey Guys, If you are interested finding out eng. RPM at any speed, check this out. WWWringpinion.com/calculators Enter the diff ratio, tire size and speed and it will give you the eng rpm. There is a chart to convert tire size to a numerical number, put that number in the box for tire size. You can play around with different ratios and tire size to determine what eng speed you want to run at. I thought it was 'pretty cool ' Jerry |
