Hello I was wondering for anyone that has installed this supercharger how do you set the tension on the belt? I accidentally ended up breaking the tensioner the 1st time around and as of now the belt started tearing so I replaced it, but it squeaks super loud at WOT, im obviously not installing it right and can't seem to fully understand the last part of the belt installation provided. Any help will be grately appreciated

Check my build thread. I chased the gremlin since I got my engine/car back in Feb (Broke 3 tensioners). from your pics, your tensioner is too loose. During WOT, your belt is stretching, and hopping the ribs. Probably slipping too. From my experience, those tensioners are junk. I got a beefier tensioner from dayco.

The shop has since put a larger walled idler pulley and put the tensioner at 85-90% tension, which from what I read that's where the tensioner needs to be at. The only way to change the belt on my set up is to remove the idler pulley. I haven't had any issues since the larger idler pulley. Still very cautious tho.

My tensioner is around where the red lines are currently.

Thanks a lot for the info I really appreciate it, the main issue I'm having is that I don't even know how to put the tension on it, that's how I broke the first tensioner I assumed it was like a regular tensioner where you just insert a 3/8 ratchet in the slot and apply pressure and ECS never responded to my email to verify the instructions. By any chance do you have the part number of the Dayco tensioner you replaced it with in case I end up breaking this one too?

Here's a link and couple of pics of their setup/install. See how the tensioner and bracket is setup. https://www.camaro5.com/forums/showthread.php?t=206369
