Kenne Bell

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.

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.

Thanks for the info fellas. People like you is what makes this forum great. You just saved my a__ from a whole bunch of headaches. Thanks again.

Correct

The term "Heat Soak" is often applied to many different things in the automotive world including Turbos/Superchargers/Trans/Diff/Engine. Typically when the thermal dissipation rate of a cooling system is exceeded.

Water based cooling efficiency is primarily affected by:
1.) Heat exchanger/radiator surface area and airflow through it
2.) Coolant capacity and circulation

Change these variables and the rate of dissipation changes.

Conductivity of the various cooling components can also change things, but nowadays most automotive cooling uses aluminum vs. copper due to weight and cost.

Maybe dropping a copper inter-cooler into the manifold would offset the issue since size cannot be changed easily.

So...I bought a 2011 used with a KB. Basically, I got the supercharger for free. And I have got junk? I have a chiller on the way(someday soon, Dave, I hope) and I bought Ted's intake pipe. Whatever

Not at all they still make great power and with the chiller you will be golden as far as heat is concerned.

Far from "junk".

I'll be tracking my car to see how the KB works this summer, but I'll be having way more mods than I have now. I can't shake that mod bug.

Keep us informed and good luck!
