  "Well, you know the problem with the rotary is......hot exhaust.....and
you know about the apex seals, don't cha".  Do you really want to rev the
engine up that much, your crank shaft may not be able to take it with a
load  Also, that is not the best prop".  "Your engine should not be surging
that way"

I do enjoy being told about rotaries.

He was right about the excessive RPM. Real racers turn up sprint racing side
port engines barely over 10,000 RPM. My bridgeported engines shift at 9,600
RPM. Periphery port short race engines shift at 10,700 and long race
peripherys  a more modest 10,300 RPM. The crazy drag racers do 12,000 RPM.

So you shoudn't rev yours very high.either. You might get it hot or hurt
those pesky apex seals.
