Pros and Cons of grinding/polishing combustion chambers smooth?
Just my opinion but i don't think I would mirror polish the combustion chamber and have proved that a mirror in the intake is a bad idea.
A mirror combustion chamber may be a good idea for detonation problem, but don't see any other advantage. Texture keep the air/fuel mixed in the port..............why wouldn't it do the same in the combustion chamber. I wouldn't polish up the combustion chamber any smoother than 80 grit on a cast iron head. here is a picture on top of a piston, that still make me go, Hmmm, was this machined????? or a nos created piston. Ask the owner of the piston but never got an answer. it was posted on facebook to show the crack on top to the piston.
If that pIston was intentionally made that way, and i think it was..........why would you want a polished combustion chamber.!?
