View Full Version : RPM/Torque/Pinion/Motor Chart?

2009.04.15, 01:28 PM
I am new to the boards. I have a MR-02 LM Yellow Porsche Lemans 2.4 GHz.
It is an awesome car, but like most I am underwhelmed by the speed of the stock motor with the 6 tooth pinion. I am planning on getting the XSpeed motor soon, and will probably go up at least a tooth to 7 or maybe even 8 for all tracks except ovals ( which I would use the 9 ).
I am just curious how much relative torque the XSpeed hs compared to the stock motor. Obviously it has more RPM, but tooth for tooth, which motor would get the car up to max speed faster?
Is there a chart that posts RPM, Torque, the two motors, and pinions anywhere here on this forum? It'd be awesome if it included a speed chart from the Tamiya speed checker too. I know this thing doesn't measure actual speed with super accuracy, but it is consistent and can easily show which conditions show faster relative speeds.

Not exactly what you are looking for, but its the closest you will find.

Yeah, that has enough info for now...
Looks like the XSpeed has pretty decent torque...better than stock. Which means I will probably run an 8 tooth with it...good speed and decent acceleration.
