CBRD new BBKB results
I know that Bryan is not gonna like this but here is what I would do. Disconnect your present boost control whatever it is. If it is a BCS and ECU boost control then disconnect the BCS and plug up all the open lines.
Reorient your DV to the stock configuration.
Run a hose from the compressor housing discharge nipple to the nipple on the WGA. Increase boost incrementally one or two turns of the turnbuckle on the end of the actuator rod at a time. It may take some time but eventually you will get it up to your target boost level of 21.5 PSI.
You may have to cut a few threads off the end of the actuator rod to get enough preload on the thing especially with the wimpy stock actuator that you are running.
I am not suggesting that you run your car this way permanently(on WG alone). But, I suspect that the wimpy stock actuator is not able to keep the flapper valve on the seat with all the exhaust that the 2.4L engine is pumping through the turbine housing.
Get yourself a proper FP HD 25 PSI actuator and an MBC, as B.J. suggested. At least, for test purposes.

Okay 
my bbk-b has died after less than 2000km's of street only use. it's making a horrid noise under even very light load. Obiovusly it is not longer being used and is coming off the car today.
I have been chasing my tail for months trying to fix a problem that was a dud turbo the entire time.
Parts fail, it's something you sign up for when modifying cars. So no ill feeling toward the CBRD brand, I think CBRD products are of very high quality and Chad provides very good after sales support. Would I buy another CBRD product in the future, yes.
Now what to choose for my next bolt on.

Running a flipped bov has killed the turbo. That is about the stupidest thing you can do because you are essentially running no bov. The resulting compressor surge has killed the turbo. If your bov leaks, buy a better one do not rig a backwards bov.
This mini-thread within a thread was full of user-end fail.
Yeah, compressor slam did it in. On a turbocharged car with an auto tranny you can get away with running sans BOV for a little while longer than on a car with a manual tranny.
Flipping the DV is also lame because as batty states it is like running without a BOV.

1.5bar actuator with thres dialed in to spray a little early. It's starts at about 3000rpm in 4th. Not 100% sure what PSI turbo is running at but as I don't have a MAP sensor and my boost gauge has just given up. But the 1byte loads from the logs are indicating that boost should be over 30psi.
I have spoken to Chad, and I must stress this is not a big CBRD bash, Chad has been as helpful as anyone who is roughly 20,000kms away can be.
edit: I am running a flipped MR BOV but have removed it and blocked off the pipes for testing with no difference.

Hrmmm so you cant log boost, and you have a flipped BOV? Im going with your going to kill that turbo very soon...

At times I think I can do everything and save a few dollars but in the end I always take it to a well known shop to give me that warm and fuzzy.

WOW ....... I flipped the BOV and blocked off the pipes for testing purposes only. 1 pull each time to see if it solved the problem. If that is enough to kill a CBRD turbo then I don't want one......
Fanboys settle down. My boost gauge has only just given up the turbo was set up running at 28-29 psi dropping to 28-27psi. I was then asked to raise it by Chad to see if it could get more. So it was raised to 33psi spike down to 29-30psi redline. It would not make anymore than that.
I did not kill this turbo..... poor manufacturing did that.

Well thats not what you said. If it was one pull then that is prob not the cause. I would not recommend it but for a quick test it isnt terrible. Sorry to hear about your bad luck. What failed? Not saying this is the case but most turbo failures are due to user error or engine problems. Take a look around your engine bay and see whats going on.
Good luck!

That's cool and I agree with you ! I would say a lot of failures are probably due to poor installation, tuning and mechanical faults such as leaks. I however was meticulous in the setup of the oil line and priming of the turbocharger prior to it being switched on.
I should have made it clearer that I was only running the BOV like that very briefly for testing, but I was only trying to demonstrate that a boost leak was not the cause of the turbo's performance problems. Even Chad himself said that the turbo was lazy and he wanted it back. But it failed before I could remove it and give it back to CBRD.
I was to busy to remove the turbo today, but am taking it off in the morning. So at this point I am not sure what has failed and as it is under warranty I will not be looking at more than what is externally visible.
As I said earlier, a big deal need not be made of this. Despite best efforts turbo's do fail and it doesn't mean CBRD are a bad manufacturer because of it..... If you want to make me out to be a noob who is at fault that's fine but it is just not the case. The turbo has had problems from day 1 and will audibly surge at 29psi which is why I did not push it past that until instructed.

Yeah, I have flipped my DV for testing purposes for a day and it didnt destroy my turbo. If you primed it before cold startup then it wasnt lack of lubrication either. Sorry to jump all over your case. I am sure that CB will take care of you.
