Andy actually pulls timing out to calm down the launch for racing. Not much and not for long but still, starting at 25 degrees? We also learned the other side of that as well. The car wouldn't run pulling more than about 6 degrees out of it. That's pretty amazing if you ask me. I've heard of some other highly efficient N/A big engines that like no more than 28-30 as well. It's become my goal, big(ish) engine that likes 28 degrees!
