math and engines dont mix. see the terrible results of turbo sizing and math i've made in the last year or so.

only to a certain degree can you put math and theory into a motor. The rest is R&D and just trying shit. Cam profiles and timing affect compression GREATLY. A 9:1 compression motor at 9psi should never ping on 93 octane right? i've driven one that did. I've also driven/tuned a car with 11:1 and 9psi on pump gas. Didnt ping a bit. Cam choice and cam timing affect when the highest cylinder pressure occurs at how many degrees ATDC. I've read/heard from the best builders that you want the highest cylinder pressure to occur 14 degrees ATDC. is there a way i can test that? not right now. until then i'll just play on the dyno with cams, cam timing, and ignition timing. And now a knock sensor is my best freind.

you are on the path to learning just open you mind a bit. i dont think 130 octane fuel exists in our racing industry. but if you have a 50 gallon drum of it from an airport your dads farm or something more power to you.
