Hi Paul n Friends, I think these graphs show the different tune for 4
speed auto trans and 6 speed manual trans. Then it would follow that the
different max torque/max power points are achieved by changing the
induction characteristics rather than the basic port timing/shape/size relationship.
Simply put,tuning for aircraft use would just be max power at "high"
rpm, as per prop needs via redux ratio, and who cares about low speed
torque. Is this not what you advocate all along Paul? Cheers, Dave

Yes. However some folks still are not convinced that tunning works
or how to go about it so I keep bringing it up :) A wankel is so
like a two stroke in that regard. The wankel is also rather limited 
as far as timing goes just like a piston ported two stroke.
