For what it's worth...I was curious if anyone else has discovered that you can use the carb heat to cool your EGTs and CHT?
My Jab 3300 works great. I was able to dial my motor in during the Phase I flight testing. Jetting and baffles are important, but the single biggest discovery was the use of Carb heat to affect the mixture.
Applying Carb Heat has the effect of thinning the density of the intake air. Soooo, applying partial carb heat during any phase of flight has the same effect as richening the mixture (as in...extra fuel for cooling!)
Although it seems counter intuitive to apply heat to an already hot engine....you will find it works quite nicely. As long as you don't apply too much and make the engine stumble, you can even do this during high power situations like climb and cruise.
I have a Dynon D180 and monitor all 6 EGT's and CHT's I can consistently keep everything in the green even on the hottest days (Of course I live in North Carolina, so that may not impress everybody)
