The WPI Xtreme Supercharger Project
This little project really started out to fix the ZZP pulley hub, the damn thing went on so tight it broke the 8mm stud and stripped out the threads in the end of my puller. I also needed to replace the snout end seal that�s been slowly leaking S/C oil. I figured while I was at it I�d put new bearings in the snout and a new coupler... might as well go the whole route.
I also wanted to clean out the throttle body, and oh-what the hell, I figured I might as well put a WPI ported blower housing on it to if I�m going through all that trouble.
The WPI Xtreme blower housing is a beautiful piece of work. Dave did a nice job on the outlet, the reduced turbulence is supposed to reduce outlet temps by 20* to 40*F.
I also got the optional coolant passage plugs, this keeps the 180* coolant from circulating through to the throttle body to cool intake temperatures even more.
Here the factory S/C is being disassembled.
I designed an adapter plate to pull the ZZP hub off and had my buddy Dave K. machine it for me, he also fixed the puller threads for me.
Once I got the ZZP hub off I spent a good 5~10 minutes working the inside with some emery cloth and a piece of scotch-brite, the hub still went on tight with anti-sieze, but it was not as bad, and did not break the stud this time.
Both S/C housings side by side. Done with the rebuild and re-assembly work, it�s almost ready for the engine.
The intake manifold is prepped and ready for the install.
One last shot of the Xtreme blower intake port before the install, Dave really opened it up and did a nice job on the blending. Compared side by side to the factory housing, the differences are obvious.
With the new blower installed, all I need to do is put my new O-rings on the fuel rail and re-install it along with the cleaned throttle body. A couple of new bottles of S/C oil and put the belt back on and I�ll be ready for the test drive.
The WPI Xtreme ported S/C housing really improves throttle response. With accompanying mods, it almost wakes the motor up as much as the cam and headers did. The S/C is moving more air at a faster rate, peak manifold pressure even went up. I can't hardly wait to put a larger throttle body and mini-AFC on it for some tuning.

My other pride and joy, my '88 Harley-Davidson Softail Custom.
It's got plenty of mods too, including Zippers Stage-II ported heads shaved .030, Jugs bored over w/oversized pistons, an Andrews cam, and a HD screemin' eagle ignition module... and much more.
My '66 Olds
Dont let the 4-doors and "historic" license plates fool you.
It's a real sleaper with 425 Super-Rocket under the hood. The 315 HP, 450 ft/lbs V8 is not lazy.
