Pulley Diamater Sizes? (SC Supercharger Kit Post-Installations)

cupcakez

Hi Everyone!

In the image attached, I have a Stillen Supercharger Kit installed into the vehicle as you can see.

In the photo, I have circled / highlighted / pointed out 4 different pulleys after the full install was completed.

I was wondering if anyone could be so kind and tell me the diameters of each pulley in the photo / verify my information based on my research.


Green Pulley = ???

Red Pulley = Stillen 8psi stock pulley that came with the kit = ???

Yellow Pulley = 3.2''?

Blue Pulley = 3.2"?

The reason I ask is so that I know when I change both pulleys on the Serpentine Jackshaft side, I would know what sizes to get to make up for any slack by reducing the size of one of them.

Right now, I have purchased a 3.47'' jackshaft supercharger side pulley to replace the yellow one, and a 3.0" supercharger pulley to replace the blue one that is right on the supercharger itself, which makes up about total of 6.47'' (Would be a bit tight because of the extra .07" added but I think I could make it fit?

But the other side for the Jackshaft serpentine side, I know that the 9 psi pulley I purchased is 2.87" which will be replacing the stock 8psi pulley (Red one), but the green pulley (idler pulley) next to that one...I do not know the exact size?

Can anyone help? Thanks, it would be much appreciated!
