That is the commonly used definition of heat soak but the incorrect one. Heat soak relates to how much heat is transferred to the blower by having it sit on a hot engine, the hot engine temps are heatsoaking the blower. This is why inlet temps are usually 10-15 degrees higher at idle and part throttle when measured from a blower's manifold, even with all the intercooling and such.

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 required to create boost pressure in the manifold. This is simple physics, you heat something as you compress it and vice versa. Its just that some blowers are more efficient at compressing than others are.

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.
