 Since increasing the lube oil flow does not increase cooling once a
critical flow is reached, it would seem that this is due to "enough to
lift the seal off of the rotor housing is enough" and more does not
help.  So, lube it is and cooling injection would probably not be
helpful for tip seal temps, altho it would still lower the charge temp
and inhibit detonation, which would allow really awesome MAPs.

I don't quite follow you Bill. "cooling injection"?

Re-read the first note --  I was thinking about whether the oil was
cooling or lubing or both.  If cooling, water methanol in the intake
might do cooling and detonation suppression.

Bill

OK Bill I lose track of the thread from time to time. The oil was cooling
only the apex seal and not the mixture. There is some evidence that too
much oil reduces the octane rating of the fuel. Unsubstantiated.
