Re: Finally finished up my setup!! Tuning to come soon!
The problem I'm having isn't the bov. I took it off today and made a block-off plate so I could see if it would build boost without the bov. Went for a drive with the block off plate installed and at 5 psi I heard the same sound I was hearing before and the boost dropped to zero while I was still at WOT.
So I don't know what the hell is going on. I try to boost and it goes up to 5 or so then drops to zero and it's smoking like mad. I did a comp test and it's good, so I can't figure out what the problem is.
I also tested my pipes for leaks and there aren't any. I'm really clueless.
Any ideas? Why would I be losing all of my boost all of a sudden like that?

This wastegate looks like the 35mm copy. I had much worse experiences with those than the 38mm copies.
To test it, you can blow in the side nipple. If air goes through, the diaphragm is blown and you need the wastegate replaced.

Re: Finally finished up my setup!! Tuning to come soon!
I tested the wastegate, blow off valve, and I tested all the pipes for leaks. There were none.
I took it to a local shop and they are 100% sure that the turbo is toast. I also had a friend of mine who is a Lexus tech check it out as well, both are convinced it's the turbo. Under load one (or both) of the wheels are contacting the housing and slowing it enough to make me lose all the boost.
I'm pulling the turbo off this morning and sending it back to Blaast, it's still under warranty so it shouldn't be a problem.
I'm really not excited about pulling everything back off though and having to send the turbo back in after only like 30 miles. But I don't really have any other choice I suppose.

no it's not a problem. Can't wait to see what actually went wrong in this turbo 
Actually, you won'T have to wait: a new CHRA will be shipped to you on Monday. Just return the bad one at your earliest convenience.

Re: Finally finished up my setup!! Tuning to come soon!
I pulled the turbo off and it turns out that there's a big chip out of one of the turbine blades!
So yeah, definately not blaast performance's fault, just shitty luck I guess.
I'm glad I figured out what it was though. lol.
With a chipped turbine blade it would get out of balance at high rpms which would cause wheel to housing contact etc. etc.
Anyways, blaast performance has been really helpful through this whole thing!

Re: Finally finished up my setup!! Tuning to come soon!
I hope it gets back together soon. Once I get my built z6 in tomorrow, I want to do another real cheap HMT kit with that turbo. I want to see how much fuel it uses at 16-17psi vs my s-trim at 10psi, as I never dyno'd the s-trim kit.
Assuming you're going to autox, the only other thing I'd suggest is possibly smoothing out the oil pump's outlet in the future. THe new oem pumps have a much larger tube at the end (for an NPT plug), which allows for full-port blending, rather than matching a 12mm pump oriface to a 17mm gallery. I'd also suggest baffeling the oil pan if you can, obviously with care to the design. It can be fucked up just like porting a head can be.
Nice setup though.
