Optimal Air Temp

Does anyone know what the optimal air temp (or range) should be just before it enters the engine? For say a 7.3 PSD?

My thinking would be cool, moist air. But thats just my thoughts on it. Out side air temp rather than under hood air, thats why the ram air thing is so popular I'm thinking.

Cool Air temp

I read this somewhere that 55 to 70 in the engine for mileage and cool as you can get for power. The guys up at the Cummins site have manuel flappers to divert turbo heat into the mix for better mileage. It's really a double edge sword. Warm air hurts performance and cool damp air has more friction on the body. Thats why they invented nitrous and methenol.

i don't know about the outside air temp, but with regard to the EGT, the sweet spot is between 600-800 degrees............

Cool air temp

I've here think'n and the test results are up a cummins .com I've never heard reads as high as you have. My oldest has a CR motor in his truck and has been working to get his intake temp manageable.
