Nice!

But why would you want an underdrive supercharger pully? Wouldn't that cause less boost and more cooling problems?

 

It is not really for a supercharged car but an N/A GTO. Less Parasitic Loss. Solid 5-10 to the rear wheels depending on the car.

The "Keyed" feature does help for supercharger applications where the is more stress on the pulley. The boost would be determinded by both the crank and the head unit pullies.

Anyways ... there is no full production kit yet for the cars so we are talking about something that doesnt come into play right now.
