Be careful with the exhaust heat. As I see it the intake air should be at it hottest while the engine is cold, and better be cold when the engine is hot. I originally wanted some regulation like drawing air from around the exhaust manifold with a fan swiched by a thermostat. Might still do that too.

Also, the heat will only be necessary under low loads and revs. The eWAI will only add 150 Watt (or 110 in my latest plan) so when the engine revs up and draws more air that air will be heated up less, just what we want.
I need a way to switch it on and off, that's what keeping me from running into the garage and build it right now.
I cannot have it heat while the engine is not running, it would melt whatever is around it. If it can warm 5 grammes of air per second it can also warm plastic at that rate. Lamp units get hot from a single 55W bulb. If I put 2 of them in a confined space ventilation is essential.
