Pick a naturally aspirated machine

Rated225 hp
At ~300 ft~223 hp

Standard atmospheric math: roughly 3% per 1,000 feet for a naturally aspirated engine. Not a dyno claim.

Turbo and supercharged cars.

A turbocharged machine (Can-Am Maverick R, Can-Am Maverick X3, CFMOTO Z10) can spin its turbo harder as the air thins, so it loses far less. We don’t put a number on that.

A supercharger breathes the same thin air, so it gives up a similar share. It just starts from much higher.
