[QUOTE="Black02GT, post: 15687802, member: 23818"] While I can not answer your question about the temperature delta directly I can add a little more science as too why it would make sense IAT2 (out of boost) would be higher with a bigger blower that's running at a higher boost level (when in boost). If the amount of cold air coming in is fixed by the amount of air the engine is ingesting (and the same as with your Eaton since the engine setup is the same) but you increase the amount of air the blower is moving with a bigger blower, the amount of air that will re-cycle through the blower via the bypass valve will increase and there fore allow more time for heat from the blower casing and intake manifold to absorb. Especially since out of boost the cold air from the filter is being mixed with the hot bypass air not replacing it. In boost the new cold air is essentially replacing the hot air. Without turning this into a calculus class there is a math problem where you pop a hole in the bottom of a tank of salt water that is being stirred and start pouring fresh water in the top. The amount of salt doesn't go down linearly because your also letting some of the fresh water out the bottom as you mix it. The math works similar to a half life (but not exponential), if you really want to know look up "differential mixing problems" and picture heat as salt and the cold air as the fresh water, the bypass becomes the mixer. When in boost you essentially stop mixing the tank (yes, over simplification if [USER=67454]@James Snover[/USER] comes out of hiding and pops in here). [/QUOTE]
