BNR turbo dyno sheets please.
Flaco, I totally understand what you mean by a BNR being a waste of time. But you also need to mention that your horsepower goals are beyond what a BNR currently supports. Im guessing your after much more than 350ish rwhp.
My horsepower goal at that time was right over 300ish but less that 350. For being a bolton turbo upgrade, it worked perfectly. I used my Racing Beat downpipe, my Greddy FMIC piping, and my stock exhaust manifold...all without any modification for the swap from stock turbo to BNR stage 4. Not to mention...practically zero headache trying to figure out how to make something work. Just a simple turbo swap and the outcome was a low 12 second car.
Great numbers!!! I know what you mean about the pulling. My 10thAE was down to 25xxlbs, and it pulled like crazy. The BNR turbos are a great match for the stock transmission gearing.

i get you 
some people just want a small goal you know i mean like if you just wanna go for 350whp then i guess do that but yeah i get u

I have a new hybrid coming out. It will be the stage 5 which uses the T61 compressor wheel that is in a TO4E compressor housing. It will be a few months before some dyno sheets come. The car runs now, just swapped out the Rtek to the haltech. Just waiting for the temps to get cooler before I go get some numbers. I am hoping to catch that 403 number.
BTW there isn't much of a power gain going to the bigger compressor housing. Spool up yes. Some wheels like the T61 need the longer diffuser wall. If the diffuser isn't long enough the compressed air will heat up causing inefficiency. The T04B compressor housings have made well into the 400 RWHP's on Rotarys with the 60-1 comrpessor wheel.

Hi Guys, just thought i'd share whats been done to my turbo after seeing what BNR has achieved.
Once i read abou the BNR turbos, i approached a good mate of mine that has knowlegde about turbos and setups.
I went for a similar setup but slightly larger using the stock location.
After him and i purchased all the parts, we went ahead with the build.
I Got my turbo back after waiting for a while as i didnt want to put pressure on him at the time.
Once i clear the epa on my car it will be going straight on.
The turbo consists of Ar.50 air reasearched comp cover,
P-Trim turbine from a T66
67mm Garrett T04z compressor wheel.
360 thrust bearing
Over sized bearings installed and all genuine Garrett parts used to rebuild.
Everything has been machined by my mate & balance by MTQ turbos (in Australia)
I will be using an external gate with this setup and hopefully be making some good street power.
What are your thoughts. please share as i would like to know what sort of power figures i will be looking at.
I'd be running no less then 14psi. and max 16 to 17psi as it is my daily.
I have a 13bt extend ported, 12a turbo injectors, Bosch 019, front mount, pod and a haltech e6k.
Cheers
Car will be tuned my Maztech Australia.

Its a series 5 exhaust housing.
A piece has been welded in the rear exhuast housing to split the exhuast gases from the turbine and the wastgate. So internal gate be remove and holes remaning open.
This is how it currently is on my other high flow. A pipe running off the plate where the wastegate holes are.
Never has a hassle with over-boost issues/spike with this setup so im sure it will work well with this puppy.

do you have any plans on offering an optional ball bearing CHRA? I would definitely send mind back for a retrofit
That was my thought too, have Bryan put a T04S BB cartridge w/ P trim exhaust wheel in S5 housing with .60 AR HiFI comp. housing on it.
Only bummer is when an apex seal takes out the exhaust wheel it is another $1,000 for a fresh cartridge I believe- not rebuildable.
But I can only imagine the spool of my set up with some BB lovin and back to non ported manifold and turbo for that twitchy boost again.

Lol...
Ok, so after spending the last hour reading through every post, when I should have been driving to little ceasar's and getting me some greasy cheese sticks...
I've come to the conclusion the the BNR stage 1 was the only turbo that has been consistent with it's hp numbers. I've heard of several people putting down 300 rwhp. People with stage 1's should chime in and comment on them

Curious, has anybody heard from Bryan @ BNR lately? I sent my turbo to him close to two weeks ago and can't get a hold of him to see if he has it. I'm hoping he's on a vacation of some sort?
ya I tried 3 times today, just got the busy tone and I emailed him 3 times last week with no response. He usually has been very quick to responding to my emails so I'm just wondering what's going on
Ended up settling with practically an s5 BNR stage 4, but without the ported housing. With the 3.5" exhaust it hits full boost by 3k rpms and pulls much harder than the stocker from there on.
I really couldn't tell ya what it is... the guy I bought it from said it was some sort of T04 hybrid and was rebuilt by BNR. The only label it had was a T with a lightning bolt crossing through it, but looking at the BNR stage III pics on his website it's clearly bigger than that. I'll post a crappy pic I took of it...
looks like a stg3 to me, i think t04b is the biggest comp housing you can fit without manifold spacers. the only difference between stg3 and stg4 is the exhaust housing porting for a p-trim wheel. whatever happended ot the one you sent to bnr?
What you have is the real T04B HiFi housing from Turbonetics (the brand with the logo).
Bryan crossed out the "T" on mine as well all those years ago when it was new. I think this is to show his dissatisfaction with Turbonetics?
I am not sure what the other BNR housing is shown is, but I have seen Bryan use both comp covers.
