How do I set up the DOS Dyno Program to calculate gear ratios and/or rollout?
The dyno tells you how fast the car has to go to do the number of laps you tell it you’re going to run in the ‘Oval Gearing Screen’. That’s the ‘MPH Needed’. The dyno also looks at the motor characteristics and information you provide to determine the average speed the car will travel for the entire race period. That’s the ‘Ave. MPH’. If the Ave MPH is the same as or faster than the MPH needed then you will likely make time. If the Ave. MPH is less then you will probably dump. ‘Track Length’ – Your dyno should have the distance your car “sees” per lap. The actual track length as measured, however… is only a starting place for your calculations. Basically, you should do this: Test a motor you want to run and save the results under the new track name. Put the motor in the car and run it with someone counting your laps. When you’re done bring up the motor test you just did and get to the oval gearing screen. Enter all the information about the run you just made with that motor. Does the
