Charge pipe blew off

[eXtremyst_v1]

I installed a UPR DVCC over the weekend. Had to take the intake manifold off to do so. I'm sure I reinstalled everything correctly, check valves are in the right position. Yesterday everything was fine and I ran boost up to around 21 psi (cobb stage 1) consistently.

This morning I floored it in 2nd above 3k RPM and heard a bump. Not like an engine knock, more like a thud from something in the engine bay. Also had a clear boost leak. So I pulled over when I could and saw the charge pipe came completely off the throttle body inlet...

I made sure to check that the worm clamp was tightened and it definitely was. I loosened it and put it back on, then tightened it again. I didn't really check if there were any other leaks or if that solved the problem completely, I had to get to work and will check later today. Does this seem more like a coincidence or does anything stick out to you guys? Any suggestions?

This was a VERY common problem on the 15s, not sure about 16s, I thought they would have had that corrected. I wouldn't worry too much as long as you got them tightened down. Trust me, you have to tighten them more than you would think. When I first heard about the problem (my car was very new), I went out and tightened all the clamps. A couple months later on a wide open pull, one blew off. Then I went out and tightened them even more, no problems since at 1.5 years and 24k miles.

I see, perhaps I didn't tighten it enough then. I'll ease it back home and tighten it down. Will update with how it goes.

You have to kind of crank the factory clamps down. I usually go over mine every 10k miles or so (every two oil changes). That's probably a bit of overkill on my part, but I've had turbo cars for a number of years and know the pain of trying to fix them in a parking lot or the side of the road, lol.

Had this problem as well, until I switched over to T-bolt clamps.

It's pretty common on the '16s too. I had a pipe pop off while I was making a pass.
Swapped out the stock pipes and no problems.

Worm gear clamps have no business being on a boosted car....switch to T-bolts and you'll never have this issue again.

Um that would be an incorrect statement

In your experience maybe, but I switched from worm gear clamps to t-bolts in my old Evo (which pushed 23 psi btw) and never had another blown-off pipe again.

I think "his experience" is pretty credible since he is the Turbosmart rep...

LOL got it, my experience means nothing because I don't sell parts.

Now now, don't be butt hurt Brian... I'm just saying I'm sure he has a lot of experience with turbos.

 

[Evolvd]

Oh I'm not...there isn't a damn thing on the internet that can butthurt me. That was sarcasm...easily mistaken for butthurt.

Charge pipe blew off?...sounds like a personal problem

Terry :lol:

Clean the contacting parts with brake clean, get all the oil off and they'll stay on fine with the stock clamps
