Heat generated from compression is a totally different thing and this is where Kennebell sucks bigtime, all blowers will heatsoak almost the same amount from sitting on a hot engine which gets hotter when you're at WOT. Kennebell screw technology is crap, so there is ALOT of heat generated by compressing the air thus generating boost pressure.
I have first hand experience with almost every type of PD blower since im assuming this is what you're interested in and Whipple was the absolute best and thats why im using it on my current build, its light years ahead of Kennebell unfortunately for KB.

I guess it depends if your talking about the IAT or the intercooler system when speaking about Heat soak.
In my definition the system is Soaked and can no longer reduce temps, Recorded this with a KB in normal city drivng with NO WOT pulls, temps just kept on climbing and even when driven down an open road would not come down.
Never seen this with any other brand
Heat Soak can be used to describe heat transfer from the Heads to the blower when not running as well.
Again Why I said this is an over used term, it explains many Scenerios.
