I'm trying to analyze some data I've pulled from a track event I was at, to see if i'm suffering from any heat-soak related power loss. I grabbed the ambient temp, intake air temp, and timing advance. I'm not sure what to do with it though, or what typical timing values would be.

Timing shows anywhere from -16˚ to 39˚. Intake air temps shoot up to 150-160˚F during the straights, and cool off to 110-120˚F during the esses most of the time, though in the beginning of the session, the cool points fall down to100-105˚F.

I can't see any correlation between timing and temp/speed. Can anyone help me out with what I should be looking for?

Timing will be pulled anytime IATs are >110F, unless you’re running race gas or E85.

Time for a better intercooler, to start.

paradoxical did a lot of work on the OG M2. Here's an interesting post on N55 cooling issues on track within his larger overall thread that might be helpful.

Thanks for the info!
