Centrifugal supercharger in a C5?

[CALL AAA]

Has anyone put a centrifugal supercharger in a C5? (2.8, 3.0 or 4.2) I looked around to find some info, but I could only find roots type blowers.
I don't plan on doing it, I'm just wondering if it has been done. It seems like a centrifugal blower could be done cheaper, if that type will work with the engine.

VF-Engineering is suppose to be coming out with one

At show and go i saw a s4 with one. Dont remember the company that made it. They told me it was around 12k. Making 500hp.

vortex?

Sure. Vortex, Paxton, Powerdyne. I don't know the advantages or disadvantages of each. As long as is moves the right amount of air (I never understood any of those graphs) and it can be mounted, AND whoever mounts it doesn't screw you on the fab costs.

You can put together a vortech kit for a pretty cheap price... most of the turbines are about $2k... you'd just need to fab a custom mounting bracket (too easy with some cad software and access to machine tools)...

Vortech also makes a piggyback fuel/timing computer, I haven't talked to them about the 4.2, but I imagine they have some baseline v8 programs that wouldn't blow your engine right off the bat... you'd just require a couple days on the dyno to get it producing power and spot on for timing/fuel.

i've been thinking about a similar thing in terms of header design... if I understand it correctly (haven't pulled my engine to check it out, because i'm in Germany right now), the 4.2 has exhaust manifolds (ala turbo cars) rather than true headers. Now, that's probably because they wanted to push the power up the rev range, but I wonder how much low-end/midrange hp/torque they sacrificed to get there? I'm really curious what equal length headers could do for this engine.
