So unfortunately while the new blower pulley is only .3” smaller than my usual one, even with the THPSI ZR1 tensioner, 10 rib belt, and griptec pulley, my car was having none of it. Instead of the expected 21-22 pounds of boost I got 15 +/- and a TON of belt dust (yes, the blower was spotless white when I left the house this morning!). Rather than push the car for no reason, I loaded up on the trailer and brought it home after two quick 1/8 mile only test runs.
Megahurtz had a great suggestion (as always) and recommended the DSX idler pulley relocation kit to greatly improve the belt wrap on my upper pulley. So I whipped out the credit card and another piece of the puzzle is on the way…hopefully I can get it installed before the track closes for the winter. I’ll give DSX credit: I placed the order at 4:21 PM and by 4:53 PM I had a tracking number… that’s good service! So fingers crossed that it arrives quickly and one of the 97 ten-rib belts I have laying around will fit…
