Be very careful when listening to info provided by these supercharger companies. It's a very small market and it seems like they all like to keep things to themselves. I've had Vortech, 928, and Superchargerrebuilds all trash talk each other, which didn't give me much confidence in the industry in general.

Vortech is only interested in selling new units or doing trade ins, which is not worth it imo. I've seen harsh mixed reviews on both 928 and SCR, so I can see how it's difficult for people to decide where to send their business. To be frank, rebuilding a supercharger is not difficult. There's even full PDF guides in how to rebuild a V3/V7 you can get off other forums.

You can use the V7 with Topgunz's kit. You will need to use a different filter though, since there's less clearance and it has a larger volute (4" vs 3.5"). Here's the deal with the V3 vs V7. You want to pick which blower will suite your power needs (For efficiency sake). If you are finalizing on somewhere around Evan's power range, then a built V3 will be much better suited. You'll also have better power under the curve. Reliability issues start becoming a coin flip once you start overspinning the blower though, so keep this in mind. This is mainly because of the closed loop setup and the oil slinger being fragile. The V7 does not utilize an oil slinger.

Buy used and private sell your V3 if you are looking go this route. I bought a slightly damaged V7 for a fraction of the cost of the blower NIB. Play the waiting game and pick up a good deal. Lurk around on ebay and the mustang/corvette forums.

Best of luck.

Thanks so much for your feedback!
I just found a shop right now saying they are willing to take on the job to rebuild the v3 sci for me as long as I can provide them with the parts and the isolated head unit.

I told him its from 928motorsports and I am looking for a shop to replace the bearings and impeller with upgraded ones.

He says he never done a supercharger rebuild before because his shop does turbo rebuilds, not superchargers.
He said if I can provide him with the PDF file for help and the parts from 928 as well as the head unit itself, he is willing to take on the job.

He does not know the price to charge as he needs to look it up in the service manual for prices lol.

Now I have 2 choices:
1) Purchase 928 upgrade package and have them ship it to me, and I give it to this shop to rebuild.

2) Send in the headunit straight to 928 have them rebuild it and send it back.

What to do....
I would assume he is more than capable of doing it because he is experienced in rebuilding turbochargers.
.and said superchargers are much more simpler.

What do you guys think? Ideas?
