    Re: Holset V-Band clamp

    So I have a silicone intakes 4" vband flange and a Columbia River Mandrel Bending v band clamp. I am going to guess that this can't work (cause its not). The Holset clamp is a lot narrower right? Seems like this one is leaking 360 degrees. Pretty darn annoying as the noise is about as long as the exhaust pipe.

    Will a real holset clamp help or will I be screwed without the flanges being exactly the same? As a cheap trick I was thinking I could make something to try to take up some of the slope (piece of metal on one side of the clamp).

    Attempting to stop the leak. "shimed" the turbine side. Hoping it will close up the gap having a little more thickness added in. Sorta annoying to make that so I hope it works. I just used some heater ducting that I had which is pretty easy to shape.

    I don't understand why these things would no longer be produced. there are probably still trucks under warranty with these clamps.

    Re: Holset V-Band clamp

    What turbos have the same turbine to downpipe clamp as the he341/351? the hy35? They have a lot of parts for the other holsets but not for the he341/351.


    BTW, I just figured out that its probably easier to seal things when you don't warp the Flange. F me.
