So what I thought was failed clutch chatter noise was actually my vortech v2sq. Don't ask how the origination of sounds confused me in the drivers seat. But anyways. I did some math on vortechs website and I was spinning my poor v2 to 59k rpm at 6500rpm. it is only rated for 52krpm.
I was making 12.5psi at redline, 12psi average. the motor is tuned for this and it ran great.
What head unit do I need from vortech now that could give me 12 psi still and be at a safe rpm limit?
I have my eye on a v3 for sale that is rated about the same rpm but max boost is higher (17 vs 21). Does this mean the boost of the V3 would come on sooner, meaning I could pulley it down safely?
Any other input?
V2 vs V3 won't have any effect on how fast you can spin it I don't believe. What matters is what trim it is; S, Si, T, etc. I'm pretty sure v2 and v3 just differentiate between self contained or non self contained oil.
Spinning it 7k over (13% over max blower rpm) for a few seconds at a time killed it?
How old/was is it?
Was it brand new when you installed it?
Was it ever rebuilt?
I bought it with the car 7k miles ago so I can't say what else. It was making 6 psi when I bought it and about two months ago I pullied it with vortech cog pullies to maximum which produced just under 12 psi.
I have only found 3 pieces of turbine fin. I have no idea where the rest could be? There is a shrot section of pipe from the supercharger outlet to the intercooler as pictured and thats where I found the first 3 pieces. The outlet of the intercooler was perfectly fine with no signs of debris and from the pic, the core is way too compact to let any other chunks of turbine fin through. Any idea where they could have gone? the supercharger is completely torn down and nothing resides within the casing.
I did open my throttle body and peaked inside with a flashlight and its clean with some oil. I was worried about that too but everything after the intercooler has luckily been spotless

Just to update everyone. I did remove my intake manifold, flushed it as well as the intercooler. The intake did have some oil in it but luckily no metal residue. The cylinder head ports looked just fine as well. I think I got lucky there.
On another note, I did acquire a slightly used V3 supercharger but I have ran into an issue today that is quite frustrating.
Everywhere in my research has shown me that v3 and v2 are basically the same externally, just one is self contained and one is engine-oil fed.
However, when I attempted to mount my v3 blower, It wouldnt line up with the bolt holes. I realized now that my old v2 was clearanced for the power steering pulley and this v3 is not. I assume that the v2 that vortech provided in this old kit was a specially modified unit just for the c5 kit, which even now I can find no information on.
The question I ask the corvette community now is, how do I proceed with getting this v3 mounted? My best thought is a smaller power steering pulley, which I will purchase tomorrow, supposed to be about 1.25" overall diameter smaller with same .66" shaft size, dorman number 300-301. But if that doesnt work, anyone else have an idea?

do procharger, those dont fail.
The vortechs and the paxton/novi ones are the ones that I hear about blowing up here.
I did take my V3 to a local fabrication company and they milled it off in 20 minutes for $45 bucks. Not a big deal to them, I was relieved. Secondly, I still had power steering pulley clearance issues with the main body. I tried a Dorman 300-301 pulley which did not work. It would not align with my other pulleys even fully pressed on. I found another pulley, Dorman 300-126 that did work perfect when fully pressed on and still shorter, 5.75" versus the 6something inches the stock pulley is. Also, it is all metal so I won't have to worry about it fracturing.
Lastly, I got the car running and drove it to work and back, 50 miles round trip. feels nice and strong. Just need to break in this clutch now...

Blew up my vortech v2
