Anybody running higher compression pistons?

[DMotorsports]

Just wondering if anybody that's done a built engine on here went with a higher compression than stock. I know that the higher comp ratio limits how much boost you can run on pump gas. Just curious if anyone has done it. I think the flat tops available with MMR builds increases it to 9.5:1.

I'm thinking about doing this if/when I ever do a built motor. As made obvious by the 5.0, the increased compression really increases the horsepower potential. Not that this is a new concept. The only catch would be I'd have to run a lower boost conservative tune for pump gas, but with race fuel imagine the possibilities.

You don't need race gas all the time. (E-85 is basically pump race gas) You just need the right set up and the people with the knowledge and those that have done it before.
