When the SP 2.0 mod motors came out they had fans. I tested motors with the full fan, 1/2 fan (milled down) and no fan. Temps were actually better with less fan and best with no fan (same track/settings)! I think this is because the the impellor puts a load on the motor relative to how fast it is turning. When a mod spools up a bit there is a lot of rpm and therefore a load on the motor not including the car it is also pushing. Think of sticking your hand out the window of a car at decent speed. The air puts a noticeable load on your hand, the same happens to the impellor. However the best reason not to run a fan is the difference in top end power, which is quite a bit.

I run my motors at zero motor timing (factory settings) . Advancing the motor timing all you are doing is creating more heat. I think Shawn Palmer made a few post regarding this in the speed passion thread while ago.

They are selling these in Japan now,but the company that imports them are not know for importing quality products. Usally they just import junk and pass it off as great.
I hope this motor is a nice motor and didnt lose any quality when it was manufactured.
I like the ideas and its nice to see something new

Just thought I would add some pictures of the fans whilst I remember.
Bigger one is the one on the 21.5t Rotor, smaller the 4.5t.
I've actually been testing a new sensor board for these motors recently... well, when I say testing, I mean proving that the older design was fine, and didn't drop the motor into sensorless mode when running boosted mod, but c'est le vie!

Thanks TryHard for the info. I've been looking at one of the 21.5s for my JRXS Type R for our local modified class and I think it'll fit my car very nicely. I use a Xerun 120 with boost but not nearly all it could do. I'm going to order tonight.
Thanks again.
Thanks again.
