So that's where I've been going wrong....I haven't been using the pistons that come in the half sizes. No wonder they have been either real tight, or real loose.[S
 
I got the impression he was referring to a 7.5:1 compression ratio but it came out as a dimension because he didn't have a clue. I think he also said he's running 3 turbos with 28 lbs of boost. Looked like he was just repeating words with little understanding.
 
OffRoad, you obviously don't know motors! He's running 7.5 inch pistons making 7.5 compression. And he is running BOTH twin turbos AND a supercharger. I believe he said boost is around 18 lbs.
