Interesting learning experience. Car has alot more bawls than before, and no other changes other than this idler.

That is what I noticed when I changed my setup too. Other then that I'd like to see the pulley up and under the supercharger pulley more like on the cobras.

My final version will be somewhere in between what I have now and what a Cobra has. Final pulley position will be determined by where the 2.0" SC pulley wants a 3.5" idler to be. Then I'll switch back to the 3" idler for the 2.2" pulley. Possibly 3.25" and 3.0", we'll see. I have all three common sizes to play with here. But I want it interchangeable in under five minutes (idler, SC pulley full swap). Right now, it is that quick.
