Hey does anyone have any info on bnr stage 3's ran sequential? I searched and cant find any numbers or anything on them only thing I can find is non-sequential any info will be appreciated, thanks.

Chance

 

I believe Rich Farrell made 415rwhp on sequential BNRs.

 

Those were on nonsequential BNRs. Rynberg made 350 rwhp on BNR sequentials.

 

was rynberg even pushing that much boost? I would also love to see an overlay comparison of the two dyno graphs.

 

I run mine sequental at 15psi and have no problems.

 

I think SPOautos (sp?) made just about 400

 

what kind of power levels are you seeing? Also, do you happen to have a dyno graph? I would love to see a comparison between sequential and non sequential with the BNR's

 

Okay...here's a thread I found. Yes, it's on a non-seq set-up but all the sequential stuff was still present. This should be an indicator of where the seq Stage III's can go.

Doesn't show the low end at all. I would like to see what the dyno of a bnr sequential setup looks like.

And would there be any longevity issues? Why is Boostd7 touting that the BNR ran sequentially will ruin turbos quickly? If the turbo is designed to run more boost, then how would it ruin it?

 

Well, I understand your frustration. I've been wanting to see a dyno of these sequentially for the longest time. But, that wouldn't keep me from getting these. It fits the purposes I have intended for my personal car.

Post 2002 I think Bryan developed a better set of the Stage III's. I haven't seen any complaints from anyone using the more recent version of the Stage III's for a while. I think the misconception from the turbos being ruined stem from the fact that it's using *some* of the stock turbo's parts. But the fact is you should be able to use these reliably at 15 psi. Of course, don't take my word for it. I just wish more of the former or current owners would chime in. I think these are still the best alternative when working with a realistic budget or dealing with an emissions heavy place of residence.

 

I made 421 non-seq. If I had a seq BNR setup, I'd probably still be running them

Correct, the newer iteration of BNRs are brand new CHRAs and rock-solid reliable.

 

BNR turbos are kinda tricky to research.

I get the impression that at one time there where a stage III (large) type but Brian no longer makes them...

Does anybody know what I'm talking about? Could that of been a one off project, or a an attempt at a stage IV BNR option?

These are what I plan on putting on my FD. I'll run it at 15 PSI, this way it can creep/spike a little into the 17 PSI area (which is their max out put, I think)

 

What the heck are you talking about? Bryan only makes the stage 3 now, I'm running them on my FD.

I vaguely remember reading about a large type stage III BNR that Bryan (sorry about the previous misspelling) had made. I'm not sure of the source... but I think it was on these forums.

Feel free to tell me if I'm wrong, I was just trying to expand on the BNR topic.

Are you running sequential or non?

I'm scrapping for any in depth "personal experience"

I am still very new to the turbo selection side of the FD, so any input is appreciated.

Most searches yield results with information on Non seq. BNR's

 

Why is it a bad idea to run synthetic with carbon seals? does it manage to leak by? (running by the old adage of : synthetic doesn't cause leaks.. it finds them)

I wonder if it would be possible for Bryan to do something that uses a seal compatible with synthetic?

After looking at those pictures and wanting to keep my setup sequential, those will definitely be my turbo upgrade once I am at that point.

 

Hopefully someone can verify this but i believe synthetic slowly breaks down the carbon seals. Now i'm not sure if this is true but it's the only answer i could get from my father since everyones answer on here when asked is "Because!!".

And i also believe you can have them use synthetic capable seals. I remember reading someone had them do that but you'll just have to ask come to for ordering.

 

That is good to know, since I personally am an avid synthetic fan. Especially since I am planning on running a separate reservoir for the OMP to inject only 2 stroke through the oil injectors. To me, the higher resistance to gumming up when exposed to extreme heat makes me feel more comfortable when dealing with the underhood temps and the two spinny thingys under there. (Disclaimer: I do not have any validate proof that synthetic is better, it is merely a personal preference that makes me feel fluffy and happy inside. Not based on any factual evidence or findings.)

If anyone has a dyno of how their BNR's performed when ran sequentially, I would be very happy to see it.

 

I'm running my set in non sequential mode.

 

I just completed a major rebuild, including stage 3 sequential. After break in and tuning, etc., I'll post. But that may be a while.

 

My set had dynamic seals, which allowed me to run synthetic.

After getting off the dyno many years ago, I ran 19 psi on them that night, and the car was friggin' *fast.* From speaking w/bryan, that's about their upper limit.

 

Do you have anymore info??? what kinda power and response are you seeing?

 

goodfellas, were you sequential or non seq?

Do you think that I would be able to run 17psi reliably in sequential mode?

 

He was running non seq. 17 psi is conceivable, but that depends on what you're idea of reliable is. If you drive the car maybe once or twice a week and have all the right mods, then I don't see why 17 would be a problem. But really, why not just do 15 with PFC and EBC for reliability and bump up to 17 for those special moments.

 

Most people doing 15 are seeing between 350-380 depending on mods. Push some more and you might see the lower end of 400. Initial boost response is usually seen somewhere just under 3k.

 

Good point! now, most people that are reporting to have response just below 3000 rpm... that is with a Non seq setup... correct?

So we could presume to have response sooner than that with a sequential setup?
