I finally got through to a human at Paxton who told me that 9.5:1 - 10:1 is the absolute max, with 9.5:1 being the conservative estimate for the max static CR to run their blower at 6 lbs boost. The tech guy told me to run 9:1 max. Even if I put on the Cometic gaskets, the lowest I can really get to is 9.9:1, which, he said, is pushing the envelop. I guess if I am going to spend the 3 large on a compressor and installation, I might as well swap out the pistons while I am at it. Assuming, of course, I end up doing it. After all, I already am at 438 hp at the crank and 351 at the wheels. Maybe I will just have to learn to live with what I got.
