The alignment checks out ok with the laser, it's locked down correctly and this belt issue will not go away.
IW wants him to pull it off again, send it back so they can check it again, etc. Needless to say, he is not a happy camper.
I doubt that this is a unique issue and wanted to see what others have done, other than switch out to the LPE part.
He is only using the OD crank pulley and does not have the complete 8 rib upgrade, can that be part of the issue?

Question. Is this happening on the dyno or just cruising around? I only ask because I had my AC belt get tossed on the dyno. No damage was done and we were spinning the blower absurdly fast. When on the dyno or track I take the AC belt of just in case. I have no issues driving on the street,
