I have looked at some Vintage and modern motors to see how they compare.
I used my "dyno"- roller test stand to check their in the car testing. I used a non-contact digital tachometer to check all R.P.M. of the motors. (same meter as used on Slot Car News website - Check-Line Digital Tachometer, has certification of testing) All testing was using the 12volt standard rating. Also Fluke 115 True RMS Multimeter was used.
NSR - Shark 20 -tested 20.2k
NSR - Shark 22 -tested 22.9k
Slot.it - Silver can - white end bell -tested 23.0k
Piranha - 21.5 - tested 22.8k (new motor)
Piranha -25 -tested 25.7k (in car)
Cartrix - s-can motor - 10.7k (in Car)
Vintage
Cox XT250 - tested 22.9k (in car) (36D)
Cox XT250 - tested 23.9k (in Car) (36D)
Cox 3500(NASCAR) - tested 35.2k (New Old Stock) (36D)
Classic - CM470 - tested 39K (New Old Stock) (26D/FT26)
I have tested some more Vintage motors(36D), new and used, they all have been 21k to 24k. Looks like the Cox NASCAR is 10,000 R.P.M. higher!!!
As you see, there is a wide range of performance difference with these motors. I haven't figured out how to test some vintage motors with pinions on them, only can test them in the cars.
