Default Where to service KB S/C on my SP360 in Ma???

Hi, I have a 1999 Shelby SP360 that came with a Kenne Bell blower from the factory. Problem is, since I bought the truck a couple months ago (used with only 12K) it isn't making boost. It will move through various levels of vacuum but won't pass the o lb on the boost gauge. It also doesn't sound like it is making any boost. I would like to take it to a shop in the Boston area... does anyone know a good place to take my truck?

I know this is probably dead but....

I have a Shelby durango and while it does not have the Kenne Bell Supercharger on it anymore (it now has a procharger) I would be willing to be that it is only the pulley that is messed up. Usually htey put aluminum pulleys with a keyway over the steel shaft so if there is a problem then it will mess up the pulley first before the steel shaft. From what I can figure out Kenne Bell does not make superchargers anymore, I think they were swallowed up by another company. I could be way of on that though. So if it is a pulley problem you will probably have to get one custom made.

lol umm KB still makes plenty of S/C's Sounds to me like a much easier issue. KB's use a bypass valave that stays open at idle and then closes with low vacuum (under hard throttle) and then creates boost. Those valves fail occasionally so all the boost is directed back into the intake side and cannot create any pressure. I would find that valve, check to see if it's closing under throttle. Just blip the gas a few times and see if it moves.

Also if it hasn'e been making boost since you bought it somone may have locked the valve into what's called valet mode where it is forced to stay open all the time thus not creating boost.

What happend to this situation???
K/B still makes superchargers.
As mentioned above if you bought it without making boost, then maybe the valet valve is the issue. Something like this happened to me too, except when it started happening was afterI took it to a mechanic for a tuneup and herouted some hoses wrong.I had a guy that works on turbos take a look at it and he fixed. It would on stay in vaccum and not into boost.
