Re: Engine Fan broke again

Yes, you are right, but an exhaust fan reduces pressure and thus restricts the air flow. An inter cooler is useful because the turbo heats the air a lot. It's hot exhaust driven and the increased pressure also heats the air even more.

A normally aspirated diesel doesn't gain much from an exhaust blower except a cooler alternator. For some installations that can be important.
