Thats interesting, since rccardr's motors pull the same type of numbers, at leat from the ones that people bought around here.
These are the numbers i just pulled off one of my 3 race used silver cans. No shenanigans here...
2v 1.06 6450rpm
5v 1.21 16350 rpm
7.2v 1.36 23400 rpm
Edit. When did they change the rpm limits for the silver cans. I could be wrong, but I thought only Tamiya Canada had strict amp draw limits and Tamiya USA did not. But thats not a big deal, cause the 13.5k is even easier to achieve.

+1 SirSwiftAlot. A Tamiya Black Sport Tuned would probably do 22,000+ @7.2v (this is a mild 23T with advanced timing motor). I use a Robotronics dyno.
Mabuchi/johnson (27T motor with retarted timing built in by design) doing these numbers cannot be legal in the spirit of the rules. Maybe if you run the motor clockwise... it might get close to a Sport Tuned. Use a Tamiya M02 mini if your club allows it
Maybe better to race using Sport Tuneds to equalize things.

Question for the silver can gurus!
Seeing as the new rules for the AV TCS for GT3 and Mini are as follows:
5.0 Volts
The 540-J motor may not exceed 12,500 rpm and 1.2 amps
7.2 Volts
The 540-J motor may not exceed 18,000 rpm and 1.2 amps
per Fred @ Tamiya:
"The above numbers are meant to encourage running the motor right out of the box. The above numbers also take into consideration the motor brushes will eventually seat in and its rpm and amp draw will increase. RPM and AMP draw numbers exceeding these ranges are clearly suspect as they may only be obtained using rare earth magnets and fancy jigs to alter the motors magnetic field to advance its timing. This voodoo is what we want out of the TCS series and to promote a fair environment."
Does this mean I shouldn't water dip or otherwise break in my new 540J motors?
In other words, should I just take a new motor out of the box, drown the bushings and slap them in the car and go?

It's sort of a crap shoot
If you're attending a TCS regional event that's using the Fred Motor Rule (and as far as I know, that's limited to Aliso and maybe Fremont), just take it out of the box, lube it, and put it in your car.
Other events using higher RPM (or no) limits, well...not so much.

Best ESC
Got an event on the weekend and a got new QC3 which my nephew just fried.. put a battery on it the wrong way. (didn't even get 1 use out of it.. just a nice smell)
So I know with 540 speedies don't make that much difference but what would be best out of the following speedies LRP Sphere TC, Keyence Rapida Pro, or a Tekin RS.. I am leaning towards the Sphere.. but its very heavy.. has anyone tested these speedies to see if one is better then the other or would they pretty much all perform the same..
Cheers

I did the same on my old LRP AI.
Just opened it up, removed the burned out diode & it sprang back into life.
Didnt even have to replace the diode
Worth a look at least

I forget...how do you tell if you have the hard or soft brushes?

I'm just going to guess you're answer will be not, based on the rapida pro suggestion - in which case, my recomendation is not for any of the above. Tekin Fx.

I think it's red dot soft white dot hard.

no sorry I have all of these speedies and I was wondering if anyone had tested to see if one was better then the other or what peoples opinions were.. I will try and repair my QC3 but need a speedie to use at a competition this weekend.. and I have these three speedies to choose from..
Thanks for your help..
Thanks for your help..
I presumed you had a brushless side requirment when you mentioned the Sphere, and then you mentioned the keyence, and then back to the RS. Umm? Do you want to be able to run brushless or not?

Pick the smallest, lightest one. You won't see a performance difference with any of these on a silver can. The RS worked great when I needed it for my guest driver Mini.
