Yes Dougboy,
Mabuchi makes most of the Tamiya 4WD and Kyosho Mini-z 130 type motors.
The Audleys are power but some other 130 type motor that is made by some unknown company... and they have seems to have less torque and RPM.
Mabuchi also makes 540 type motor for 1:10 scale Tamiya RC cars.
If you go to the following website, you can get all the data you want. ie (max efficiency, max torque, max rpm, max power output etc....)
