I have not tested the continuous power levels for a couple of reasons. However, the airflow is decent through the motor and they run much cooler than without the fan cooling (obviously). There are a couple cool developments I have in the works that will take this cooling idea even further. I am pushing for the absolute ultimate cooling ability possible! I have looked into liquid cooling (I have much experience in this from liquid cooling car audio amplifiers in my past), but I am not going that route for many reasons, not the least of which is added complexity and considerable added cost. These motors cost enough as it is. However, I believe I have a design that will perform every bit as well as liquid cooling. Basically, I am taking the air cooling to the logical limit, per Motomoto's cooling design with his help, as well as taking the "Pulling heat out of the housing" idea that my DaVinci drive uses to the limit as well. I am pushing for the absolute ultimate high output motor from this size factor that can be achieved. I am also making it as good looking as possible. I find no good reason to make something ugly, just for performance reasons. I mean, don't get me wrong, performance (especially in racing) is the most important thing. However, when starting from scratch with a blank piece of paper on the design and having complete control over how it is done, why not make it look insane as well as perform at the limit?
Anyway, yes, a 160 is fine to run this motor. That is mainly because the 160 is already running well at high power levels (as long as the throttle setting is high, such as in racing or Pike's Peak climbing). It is the motors that are having heat problems now (hence the fan cooling). What I am trying to accomplish is a true power output of 7,000 minimum, preferably 8,000 watt continuous power handling. When I say continuous, I mean continuous, as in endless. Judging by the results of various cooling experiments we have done so far, this looks not only doable, but surpassable. The 160 is fine with this output assuming it is above 60 or 70% throttle setting for the majority of high output running. I see no reason why it would not be if being pushed so hard.
I hope to see a few of these new motors in a few race bikes this year being put through their paces.
