How much compression have you guys got away with on pump gas?
I'm in the final stages of an engine assembly where I'm tweaking things to reduce a greater than 12:1 compression ratio resulting from small chamber heads. My pistons are currently flat top, which alot of guys seem to consider optimal for flame travel, etc., so I'm leary of putting too big of a dish in them. I will be ceramic coating the chambers and piston tops. Any "data points" out there for max compression utilized would be appreciated. Thanks
