Towing with a Powerstroke 7.3L (expectation/realistic)

...

Thanks for some good info guys. I'm a bit surprised at the low exhaust cooling gain by adding an intercooler to the earlier, non-intercooler engines though. Unless the intercooler simply caused a notable more aggressive low rpm charge burn, resulting in a lot more power.

I understand there is a physical ceiling to limiting exhaust temps as a fixed displacement achieves high HP while remaining at mediocre rpm's. The 7.3L is not normally a good free revver. Is that what happens?
