With the Bore and Stroke being 79.5 and 85 mm, that is a good combination for a high rev engine. Under square = higher revs/higher HP, over square (think stroker) = lower revs/higher torque. I'm sure with these specs that this combination can obtain the 10k RPM.



 -------------- Original message ----------------------
 Ultimately, to make those power levels, one would have to design an engine that 
 is able to run at quite high rpm... and be willing to deal with a power band 
 that begins at a high rpm level.  My guess is that such an engine would be 
literally dead below 6000 rpm.  If he actually did design the engine like this, 
 that would explain motorcycle pistons and such... low rotating mass... 10k+ rpm 
 capabilities.
