Default Re: monitoring intake temps

Subscribe... (needed some #'s for comparison with the logging that I'm doing...)

Comments / questions.

1. Based on my calculations (based on vague memories about gas laws) I believe there is a ~1% power loss for every 3 degree C rise in the plenum air temp. (This is assuming that HP is directly linked to the # of air molecules you can stuff into the combustion chamber which I believe is correct.)

2. Is the larger issue that higher intake charge temps can lead to detonation which will retard timing?
