Whippled 06 300C Srt8

The plastic idler pulley adjacent to the water pump pulley is too narrow.  I ordered a dayco steel pulley that's almost twice as wide and about the same circumference.  I am also using the GT 500 tensioner with the adapter plate.  That combo seems to be working pretty good.  I'm not sure why the ARS tensioner did not work as well for me.  Those tensioners (street and race version) have significant more spring pressure, so I can't explain the better results with the GT 500.

Going to upgrade from a 6 rib to a 8 rib setup. Hoping that will cure some of my issues ( snapping belts and tensioner bouncing). I also recently increased the size of some of the idler pulleys to give me more belt wrap. Would like to make it to the track soon to see if I can pull off a 10.5 sec run.
