'05 CTS-V Custom Supercharger Install
I have finally started on the install of a centrifugal supercharger on my 2005 CTS-V.
The ONLY supercharger kits available for my car is a top mounted magnacharger which costs $5,500+. Therefore, I decided to do it my own way...
The kit I bought was a used LS1 F-body Powerdyne Scorpion XB1A setup. Most people love to hate on the powerdyne units and mostly because of the failure of the internal belt drive design. However, the XB1a is one of the last models they made before going under and uses a gear drive internals. This particular head unit also came with a ported impeller for better performance.
As I progress with this build I will Update and add pictures and information.
Just for those wondering later on when looking at the pics, all the radiator stuff and other components will be replaced with different size aftermarket ones and moved forward to make the room required. I have it planned out, don't worry.
So far, I have removed the front bumper, air box, cooling fans, radiator, and a/c condenser. I put the f-body mounting bracket in place on the engine and it will bolt up and hold the blower unit, but due to a 1/2" difference in the cts-v alternator bracket vs. the f-body one, the heads of the bolts that mount the blower will hit the alternator pulley. One option was to try to mount an f-body alt and bracket, but the belt sits at a different depth on the 2 cars so that's a pain. I just decided to fabricate a new mounting bracket for the blower itself that moved it 1/2" over to clear the alternator pulley. I measured the stock plate which was 3/8" think aluminum and ordered up a plate slightly larger that I will be cutting out once I have the final shape design. I went with a 6061 aluminum alloy for strength and corrosion resistance. I also had to get/make new spacers to mount the bracket to the engine side. I measured to f-body ones and they were 1" diameter with 7/16" holes in the center. I then ordered a foot of 1" diameter rod of 7075 aluminum alloy(aircraft grade). I will measure the length I need for the spacers and cut them off the rod and drill a center hole.
Here are some random pictures so far...

lol. That paper bag is actually 2 buttered bagels. The engine was still hot when I started working on the tear down, so I put them up there to let the butter melt.
And my ultimate goal is to make over 500rwhp. I may do a cam swap to help with that though. And there will be an intercooler on the setup as well.

What are you doing for a blower inlet? Looks tight.

you are gonna love the sound of that s/c. straight cut gears in it so its got that coffe grinding whistle...lol
use a gatorback belt & a pulley from robinson racing (they have notches in them for more grip)
p.s. you need a manual tensioner too.

In the pic the A/c condenser was still there, that's all moved out now. Once I have the inlet hat on, then I will fit everything in front of it.
I also have yet to find a place to buy low profile inlet hats. I may have to work with what I have or fab one up, which is what I will probably do

yea i remember, I still have you'r PM all about it too. The only manual one i found so far was on thunder racing, since i need a c5 vette one.
I still have to buy an oil pump and reservoir since ill be running a stand alone oiling system too.

Check out the truck inlet hat from procharger. It should work fine for your power level.

Who needs an alternator? Can't wait to see this done man. How much boost are you planning and how much can the bottom end handle?

Maggie does fit, but it's very common in the V1 crowd... and that's just not Paul's style!

Maggies get limited to max HP very quickly, even with 90mm snout mod and all.
With this setup, in the future when I build the motor, I can upgrade to a procharger head unit and keep building HP.
I will be running at 11psi according to current plans.
Bottom end can hold whatever it can, lol. When(not if) it blows, it will get built up.
I'm already collecting parts to build a spare LSx motor on the side to swap in on short notice.

Update:
Today is the second day I actually did anything regarding this car... lol.
I made the new blower bracket this afternoon. Next day I get around to working on the car, I'll actually bolt the blower on it.
Original LS1 F-Body bracket on top, 7"x10" plate of 3/8" thick 6061 Aluminum underneath...
Original bracket of left, new larger bracket main shape cut out and edges finished...
New bracket drilled and finished on the left, original bracket on right.
