Engine Breathing

Post by TXGOAT2 » Thu Jul 28, 2022 1:04 pm

Could adding a high compression head be expected to improve engine breathing? I'd think a reduced clearance volume would make the engine a more efficient "air pump" and thus increase power. I'd think a performance cam would work better with a smaller clearance volume as well.

Pat it would be at least more efficient based on physics, even more so if you added a high volume intake.

Just a suggestion: Find the writings of Phil Irving and the development of the cylinder head for flat heads (motorcycle) or information on the "Ricardo" type cylinder head.
