Help finding belt tensioner?

Posted by CarpenterUpset1803@reddit | projectcar | View on Reddit | 12 comments

Hey guys I’m new to the sub but I’ve ran into an issue on my buddy’s car. He has a 2006 c6 z51 with a LS2 and a vortec v3t super charger. We are having trouble finding a replacement belt tensioner. Here are the pics we have of the original tensioner and a replacement one he ordered from vortec that is not correct. Also have attached photos of the supercharger. Thanks for the help guys and hopefully we can get the correct one ordered. Part number on the tensioner comes back to nothing

There's a number stamped in to the pulley arm by the cast in numbers that's probably a part number

Go to summit racing and look up comp cams tensioner for that car.

That's a solid tensioner and with a blower you really need a spring loaded tensioner to take up the slack when the belt stretches to stop it from slipping

Looked at it and it looks like it could maybe work but idk. Hoping to find the one that came with the kit.

Ditch the spring tensioner and put a manual tensioner on it

That looks like an OEM tensioner assembly with a different pulley pressed onto it

Im starting to lean towards the same idea. Just confused on what specific tensioner and where it comes originally on the motor. Every-time I try and search for the specific model and year it only comes up with the chain tensioner surprisingly
