      Does this polish Whipple heat up more than a none polished whipple? Does this polish Whipple heat up more than a none polished whipple? I like the look but don't want to give up HP

      • External casing temperatures should have minimal (if any) difference between the finishes. If you've lived with a supercharger for a while though, you'll know that trying to keep a regular one clean is a TOTAL pain in the butt, much less a polished one.
