And what high revving NA engine? My GSXR race bike spun to 14K, and the Yammy's were spinning to 17.5K. My Ducati twin was a low revver and it had a redline much higher than the M3.
yeah, there's lots of turbo cars in pro racing...... maybe the turbodiesel audi's in the ALMS but not much else.
and planes pretty much use jet engines now
bike engines are so much smaller than car engines, that's the main reason they can rev so much higher, redline is determined by the max speed of the piston, and when the stroke is shorter, you can rev higher.
you can't compare bike engines to car engines
unless your car displaces 1 liter or less (geo metro)
