All mass-produced motors have a production tolerance which can make a big difference. Just ask the serious racing guys.
We stock the Scalextric motors, and regularly get customers wanting to run them up to hear the tone. Some are real screamers, some are noticeably slow, but most fall into an average 80% band.
I think you'll find most racers have around a dozen motors in their pit boxes, as revs are not everyting. Sometimes a slow sounding motor can have more torque or resp[ond better to a poor power supply. This is normally due to the commutator timing which is set at assembly. More advance can mean more revs but at the cost of heat buildup.
Best adice is to try some different motors and see the results.
By the way, the type of car and colour of bodywork has no bearing on the motor performance. Anyone who thinks otherwise should ask themsleves why they beleive this ?
