***Topgunz ROTREX C38R Supercharger Kit***

The Topgunz kit is superior in that regard, I'm not sure if they were more conservative to get it CARB approved in the future but it seems to be track tested so cooling appears to be dialed in.

I think that if Topgun had better marketing of its products with some revisions to its fit and finish it would definitely be more recognized and appeal to more people.
