It may be hard to read the actual inside diameter with the belt on. We could just read the outside, just to make sure I have the correct size.

I also double checked that 2 pulleys were changed out.
hows belt tension??

is the boost gauge accurate?? consider ghetto rigging a mecanical unit and just run the lines through the hood/windshield way... i then held the unit in my hand and did a long 3rd gear pull as it climbs slower....
