Does anyone know the size or have a link of where to buy the v band clamp between hot and cold side? Car is a 2011 335i e90. I've searched a bunch and can't believe I can't find it. It's always the downpipe clamp. I just installed a ps1 and am getting an oil leak between the hot and cold side it looks like. So I tightened up the clamp hoping that stops it but the bolt on the clamp is bent now and I think I've compromised it's strength. Side note I replaced all the coolant and oil feed/drain lines and the turbo appears dry around all the new lines. Just have oil on the clamp. Could a loose clamp when I installed it cause a leak?

Sorry mods I just realized I posted this in the n54 section. Please move to n55 if possible

I'm gonna assume there's another issue if you tightened it so much that it bent the bolt and it's still leaking…it shouldn't be leaking out of the box from Pure anyway.

To be fair I haven't tested it yet after tightening it. I'm nervous the clamp may break so I'm looking for a new clamp. Pure is helping me work through this, I'm new to working with turbos so I'm not sure if tightening it is going to stop the leak or not. It was just a hope. The top of the turbo was dry so we will see…

Yeah just talk to pure, I'm sure they will get you right if you bought directly from them. How much power will you be making with that? Just curious.

I'm not sure on power, based on what it says online I'm Fbo but it's a pwg n55 so maybe around 360-370 whp? We only have 92 here no e85 and I don't have meth so it think that's what I read it should be at. I think the ps1 cars making 400whp + are on e85

Did you ever find where to get this clamp from, mine is non existent and I need a new one! Thanks.

My clamp is also completely missing and I cant seem to find a replacement anywhere. Did anyone find this?
