RJ MFG Supercharger kit Feeler...

The whole point of a cog setup is to reduce the amount of tension needed and thus not put as much stress on the bearings in the snout and on the crank pulley.

And reduce/eliminate belt slippage,as I've seen where slippage can accelerate the wear on the main bearings.

Interesting. If you talk to vortech, they tell you that a certain amount of slip is required for longevity of the supercharger. They in fact encourage a certain amount of slip and told me if you completely eliminate it, it is tough on the bearings.

Which makes sense, just like if your tires let go on the street. If they would never slip, we would see a lot more snapped axles and driveshafts.

I do know COG will make a whinning noise compared to ribbed. It is caused from the when the belt meets the cog, it squeezes air out so quickly and repeatedly that a whinning noise is made. In fact, on some setups this is what you hear over the supercharger. It is not going to sound like a firetruck by any means but it will be audible. However, to the point of good taste. I love it.
