I have been thinking about going all electric so that I can flip it on at any time to keep the temp down. There are times when I'll be at idle on the trail in the summer and the temp rises.
I have also been thinking about a fan powered cowl inducted hood. instead of using it to force air into the engine, use to to draw hot air out of the engine bay. The intake temp can get really high during the summer when idling on the trail.
