A hose come off?

 

I could not hear any leaks. The blower had no whine like it usually does under boost. Also tried to check every vacuum line I could and nothing out of the ordinary. Thanks.

 

Check you bypass valve and make sure the actuator arm didn't pop off of the valve. If it is connected properly blip the throtte and see if it moves, it should. Chances are if the line had of come off of it it would be in the closed position and be making boost all of the time, but you wouldn't get a correct reading on your gauge if it is tied into the same line.

I checked the bypass valve and it seems to be working and did not pop off. The only thing I did in between runs was reinstall my custom tune, could this have anything to do with this problem. Thanks. Lewis.

 

In the snout of the KB there is a nylon hub that is designed to absorb shock, or break free if the rotors lock up. Over time the hub will wear out and break.. It alows the pulley to spin free god forbid anything happends to the rotors.. Parts for this are like 60 bucks or so.. My buddy's did this. the install was not bad.. take the belt and pulley off then remove the snout.. or depending on how new it is and how mechicanically apt you are send it to KB.

So it is just an all of a sudden thing, no warning. I guess he knew that was the problem by checking it like Rod said take the belt off and if no resistance then that's probably the culprit. Thanks very much for the info.

 

Thanks guys. I appreciate all of the advice I will try to check the pulley resistance and see if that is the problem. I believe you guys are more than likely right on, I will keep you posted as soon as I check it out. Thanks again.

 

.....had it happen, on 2.2 though.

2 bolts can break. 1 in the snout, or 1 in the mating
surface of the rotors for lack of better terms.

If your belt is on, and you aren't hearing boost under
the hood revving, you've sheered a bolt.

 

Take off the allen bolts around the snout. Inside there is another bolt similar to the bolt that holds the pulley on. It is has probably snapped.

 

You were right on, the allen head bolt that holds the coupler housing to the blower snapped. Luckily I took a scratch awl (I believe that's what they are called, a pointy screwdriver) and backed the broken bolt out. Thanks again for everyones help. I guess I'll call KB and try to get another one.

 

WOW, glad you found that. BTW, I just realized who you are! How the hell have you been bud?

I've been great. The cars been running great with exception of this OFB. I'm going to try and get in touch KB in the morning and see what the deal is.

 

I just wanted to let everyone that replied to my thread that I replaced the 10mm bolt with 12mm upgrade provided by KB free of charge. I wanted to thank you guys that helped me diagnose and thank KB.

 

AWESOME! That means this bolt is also vented all the way through, which will prevent oil spray if you go to a smaller pulley eventually. Was your last one not?

No I don't guess the last bolt was, I believe you said that you pulled the snout off and rotated it in the correct position before you shipped it to me. They did not send me the pulley bolt, just the bolt that holds the coupler to the blower itself (went from 10mm to 12mm).

 

Ahhhh, okay, yeah I got ya. Yes, I did fix that for you.
