Do KB blowers still lock up?
This should help.. A few names should look familiar....

I had a theory that the intake manifold wasn't flat and was distorting the blower case. The reason I thought that was because I had to remachine my own manifold and it was not flat by a bunch.
I tried explaining that over on that site and the thread got locked. I think JJ complained to the Mod and had it shut down because I was not agreeing with him. Or maybe it had something to do with KB being a SV.... Whatever....I thought it was good information for everybody but somebody didn't think so.

There were a few that locked up in the prototype stages, but that was fixed a long time ago. The issues were due to clearance of the rotors and the casing. There were a lot of factors like the blowers being torqued wrong, intakes not exactly true, etc. To get around all of these issues, KB changed a few things(more forgiving) and all has been well since.

Nick is on his 9 th blower. KB has been great about replacing them with new ones. If the 9th blower doesn't hold up, then Nick's is getting his money back.

Mine had around 20K when it started making a noise. KB warrantied it and I sold the new one they sent me back. Then the little ebay thief sold it several more times.

From KC@KB...
Our investigation indicates the only ones that ever came back were ones that ran "hot air" filters (exposed under hood filters). We have a lot of them out there running perfectly that are from the first production run on those trucks using true cold air kits.
All the ones that ever came back were damaged at the point of entry where the bypass valve feeds air back into the inlet. Temperatures under the hood can exceed 200 deg F and when mixed with the bypassed air, this can exceed the maximum temperature threshold for the rotors. From our analysis so far, this appears not to be a rotor-to-case clearance issue or rotor-to-rotor clearance issue, it is a hot air temperature issue.
When any supercharger is run at very high boost levels, this becomes extremely critical, so DON'T RUN OPEN ELEMENT FILTERS BECAUSE YOU THINK THEY "FLOW MORE". Not much air flows on a locked up supercharger! Why do ALL the OEM's spend millions on encasing their filters and drawing air from outside the engine compartment?
BTW: We appreciate your concern. We as concerned as you if not more. All indicators so far are temperature related, so that is where we want everyone to concentrate. If you are running an exposed filter, get rid of it and install a cold air kit right away.
If we can get a Lightning guy to come by Kenne Bell, we will look into designing and offering a true cold air kit ourselves. We ran a bunch of tests on the factory fenderwell intake, and it was restrictive at high boost levels, so we understand why some are choosing to go with hi-flow filters, but you must find a way to get the air from outside the engine compartment - this will help save your supercharger from damage.
From everyone at Kenne Bell, have a safe holiday.
