Anyone running it? What belt are you using? Looks like a deal from summit.

I believe mine is a 2.85" pulley (10%). I run the stock size belt but I have changed all the tensioner to steel pullies instead of plastic. They are all the same size and the stock plastic blower tensioner pulley was a little smaller. I don't notice any belt slip.

I got the pullies at Auto Zone they were about $15-20 each but I don't remember the part number anymore since it was about 4 years ago when I did it. Both of my cars have them w/ 10% overdrive.
