This is a kit I made about a year and a half ago. The pulleys included will max out a D1SC blower at 6700 RPM. The bracket is made out of steel; I did that to get rid of the vibration. The idler pulley is about 2x as big as the one in the ATI kit, so I'm sure the bearings will last allot longer. If you look at the picture of the back of the bracket you can see how you adjust the tension. I had to adjust the tension about ever 1500 miles of hard driving. Also included is the crank pulley adapter that allows you to use the ATI spacer. I made a little over 20PSI of boost, bear in mind that I have near stock heads and shorty headers.

I'm asking $475 obo, feel free to call or email me sean_94z@yahoo.com (928-486-9694).
