Re: Fact-Checking Needed
"most are at their highest torque/power at the top end as well"
This is always the case in petrol engines, hence why race engines have tiny cylinders and stupidly high max rpms. (Back in the 1950s Ducati was making V8 500cc motorbikes and in the 1960s Honda had 4 cylinder 50cc ones. I'd love to have either as a collectors' item.)
Internal friction losses go up with the cube+ of piston velocity, just as rolling air friction does. There's always a tradeoff.
