Gary: It might be the RPM at which the aftermarket stator is rated - 3500 RPM.
I would guess that max. output is not until much higher RPM, which is where BMW is getting the 400W max. output.

Cowboy: That sounds encouraging - how did you measure the temperature / temperature difference?

BudMore: Likely it will depend on the skidplate - note that the BMW version has some slots that let air pass thru, while some others do not have any slots. I'm not sure if the BMW design was an intensional addition for stator cooling or not... just my observation ... some skid plates pretty much block all airflow accross the engine covers... this can not be a good thing..........

a 10C degree temperature rise makes things happen roughly twice as fast...

e.g. insulation likely breaks down twice as fast for every 10 degrees C ..................

If oil were flowing into the stator area life would be much better ... alas, as Joel points out, there does not appear to be any provision for oil to circulate in that stator area ... thus ... it gets pretty damn hot when paired with a regulator design that runs the windings at 100% load.................

IMHO any and all methods that would reduce the average operating temperatue of the stator would pay huge dividends......

I gotta go now.............
