procharger does not recommend it, they said it will pull the input shaft out of it

Whats a ds 1? Did you mean D1sc? If so, like stated above, it's not recommended. The transmission was not designed for it. I've heard of guys getting away with it using that sprag type pulley, but its expensive.

So a Cog increases tension on the pulley? I wouldve thought the opposite, mind you i know nothing about superchargers other then what i read...

I honestly thought a cog wouldnt add any extra tension????

I dont know if it really pulls any harder on the input shaft but the trans. is not built strong enough to hold the no slip cog belt, from what I understand is that a serp. belt allows some slip if you have to peddle the car where a cog belt jerks back and forth on the trans

As far as I know, everyone who bought our old cog drive kit used them with F series blowers.

We did not know we had mid range rpm belt slippage until we swapped to the cog, it became a whole different beast. Before we added braces to the bracket, you could watch the bracket really move around while doing a pull on the dyno.

ProCharger does not recommend a cog system on any D-1SC, the torque that is applied to the blower is much greater than it is with a serpentine belt. Bob
