I emailed Bryan to see what he has to say, but after talking with Rick, it sounds like it's just the characterstics of the BNRs.

It's just a totally different application.

Well, there's a big difference between a seminar and the real world... Look at Cummins or Caterpillar -- I don't think they make a single diesel engine that way.
Other BNR owners have had no problems with hitting high levels of boost on the primary. I have never seen a fully working set of BNRs out of 4 or 5 sets. I think you need to have Bryan redo them or give you your money back.

sounds like a reasonable idea overall but i wonder how hot the air would be after being compressed by the 2nd turbo. it is likely this increase in primary turbo intake temperature could negate the added pressure of the intake charge. of course, since the stock intake system does dump this into the stock airbox it makes you wonder i think we need some real world testing with a couple of boost and temperature gauges.

I'm going to give it a try and see what happens, but it probably won't be super soon since it means taking the pipe out, doing some metal fabrication, and having someone weld it up for me. Just wanted to see if there was something obvious I was overlooking before I did this.
