Only thing I am wondering about is the pulley set up as I am running the brackets for the top mount a/c compressor. Called Raylar but haven't heard back form them. We will see where that goes.

The guy I got my 8.1 from put a Raylar supercharger on an 8.1 in his 3/4 ton Yukon XL. He later used it on a PSI 8.8 block with a stroker crank that makes 9.5L and the blower. I got to ride in with the blown 8.1. Rowdy. I'll put it this way, with the 8.1 it was way quicker than a 3/4 ton Yukon was ever intended. With the 9.5 he told me it loses traction in 3rd gear north of 60mph.

As fun as it was, for what I do with mine it would be complete overkill. It's worth every penny though. I saw it before he installed it. It was very well done.
