The rotor cooling is fine for the most part. I use a 180 Webber main jet in
the crank. With racing bearings I can run flat out shifting at 9,300 RPM with
the oil temp under 200 degrees with good reliability. Anything over 170 will
cost you power. The oil temp is important only because the rotor bearing
strength starts to become questionable when the oil is above 200 degrees.
The rotor and bearing are much hotter than 200 but the oil cooling the rotor
bearing is the important part of the problem. This looks to me to be an
opportunity to use racing bearings in both the rotor and main bearings to get
higher flow rates across the bearings and still have the pressure relief
valve controlling the maximum pressure. You can use an early pressure relief
and jack the pressure up to 85-90 PSI.
