true, very true! i just thought that this tool could be useful, the only way i could test speed before was to run my car naext to a real car, though this is not 100% accurate. also know i can find out how much faster a modified would make me go.

Without seeing the program I assume it just takes the circumference off you tires multiplied by (motor RPMs / internal ratio)

But how do you know how many RPM's your motor will make? This will depend on the track, tires, body, wind et. etc.

i suppose when you get your motor some have a dyno readout with rpm on it also some websites have approx rpm for motors. yes that is how it works

The RPM's stated by websites, on the motor or on the dyno will never be the RPMs the motor reaches since the loads are different.
