Not sure you remember at the time i was talking about bumping it up, most on here said it wouldn't gain much if anything. I can agree with that. I was talking to Wilsons one day and they told me any time the air slows down in the intake port, the fuel can fall out of suspension. Compression can speed things up on both intake and exhaust. My theory was at the time that my MW victors had lazy ports and more compression might be the fix and i believe it was. Helped the border line cam as well. so, maybe 1 point compression wont help everyone in every situation, but from this point i will always have at least 12.0:1 compression in every motor i build and just run good gas. They just seem to be happier with more compression.
