Wow! That's like kryptonite to Superman!!
What a dog. It felt like a regular car.
Couldn't believe how dramatic the change was.
Now I'm seeing the importance of the supercharger cooling kit.
Headin' to the track on Sept. 14 for a day of lapping. Gotta get that installed before then!

Can someone explain how/why performance suffers when the supercharger overheats?

I am sure someone will chime in with something much more technical, but in a nutshell it is all about your IAT's or Intake Air Temps.

As they increase (do to compressing of air), it becomes much more dangerous for your engine and the ECU begins to compensate by pulling timing and dumping fuel on you. When that does not work, ECU shuts down the supercharger in a last ditch effort not to run the car ultra hot.

Not sure if you could end up detonating/toasting a piston/or something else.

It's something nasty for sure.

When the IATs get too high, compressing them can lead to increased cylinder combustion temperatures, detonation and knock... potentially causing cylinder damage and catastrophic cylinder pressure increases... in other words bad things man, bad things.

+1, IAT temps go up, ecu dumps more fuel and pulls timing...HP goes down. It's your ECU playing big brother and not letting you get your self into trouble.

Additonally, on our cars or any other, hotter air pulled into the engine is much less dense than colder air. Less dense air means the engine creates less HP.
