The RPM rating of a motor does not tell the whole story about how you can expect it to perform on the track. The motor's torque is also a factor, if the motor's torque and RPMs are known the actual power can be calculared and in the case of slot car motors that is usually expressed in watts. In most cases motors with equal power ratings can be expected to have equal performance, provided that the car is geared correctly. Differences in the weights, dimentions and magnetic downforce of different motors will all have some effect on a car's performance. You might take a look at this listing:
There is also a version of this list as an Excel spreadsheet which is easier to sort through. I did my own version of that spreadsheet that has watts as a separate column so I can sort the list by power ratings. If anyone is interested PM me with your e-mail and I can send you a copy of that file.
