I'm wondering... Where is the sensor for the outside thermometer located?
When the car sits it builds up temperature. I notice that once I start moving, even slowly, the temp goes down very quickly. Might this be an indicator of how quickly the hot air in the engine compartment is exchanged? Let me add, that I removed the baffles that hold the stock air tubes in the front. That lets in more air.
Another question is just what is the power difference between hot, warm and cold air? Sure, the hotter the air, the less oxygen, but is there any hard proof of how much that really affects combustion, or is this to some extent just a case of everyone accepting things, because "thats how it's always been"?
