I still think the tensioner is too weak for such a long belt, I can move it by hand. My Audi 4 banger has a much more robust tensioner and the original GM tensioner for the long belt was very robust. I have over 20 hours and $150 in belts/tensioners in trying to get this thing to work.

On a side note, every time I request a refund from Vintage Air they send me to Kwik. The Kwik folks said they had a new prototype to fix issues and would send me one but never have. I am getting pretty annoyed that VA keeps sending me to Kwik when VA is the one that sold me the kit.

Sorry - haven’t checked in for a bit. I am using all the stock pulleys and alternator that came with my 2006 LQ4 truck motor, with the Kwik AC bracket and whatever tensioner comes with the kit. I am using a MasterPro K061130 belt. Seems to work fine at this point.
