Why did Powerdyne decide to tension down onto the supercharger belt instead of pulling up from the bottom portion?

Agreed, it’s done for manufacturing ease. You’d have to fabricate a pretty hefty plate to reliably move it to the slack side.

The tensioner is on the wrong side of the belt an automatic tensioner has spring in it you don't want your belt to spring you want the manual tensioner to keep the belt always at the same tension automatic spring loaded tensioner will not work on that side of the belt must be manual.

I agree. The belt is going to tension better with a manual. The auto is going to just flex every time it gets loaded, and will get more slack with more load.

So we came up with this with Powerdyne. Coming off of the lower alternator bracket we put an idler pulley that basically puts pressure on the bottom of the supercharger belt and then tensioned it to the appropriate tension measured using Gates KriKit tool
