new BNR upgrade PICS!!!
 

Hey guys, just thought I'd share some pics I took. Bryan came by the house a while ago with a set of upgrades for me to check out. I thought I'd snap a few pics to share with you guys

Pic of primary turbo...

mmm nice and clean turbos.. my favorite

How much HP increase they sposed to make?

pic of secondary....

Very nice, will be my first choice when mine fail.

I dont know how to make them show up as pics so maybe someone can do that for me or tell me how to do it.

Like mentioned on the other thread, the internals of these turbos are entirely brand new, there's not one part inside that's OEM, its all high quality aftermarket parts. The only thing stock about them is the housings and really, they arent stock either cause he spend forever cutting away at them and making adapters so that the new parts would adapt into the oem housings.

As for the HP, well I'm not sure about that yet. He's going to be testing them to thier limits on a dyno the first weekend of March.

Anyway, hope you guys like the pics, I just wated to share

STEPHEN

Those are going to one of my customers, so tell him to get them sent :)

Jason

Yup, they are going out in the mail in the morning. He stopped by my place to show them to me before they are mailed off.

I think your customer will be VERY happy, man they look awsome.

STEPHEN

Sweet :D

im intrested too, keep us updated on hp numbers

Are these the newly upgraded stage 3's or what?

I can't believe you are taking a picture of the turbos on top of wood shavings ;)

I noticed something interesting on the Extrudehone site....
They said they also do turbo impellers. They didn't mention it but I'm sure they would also do the housings. I wonder exactly how much of a differance would it make :scratch:

They look good but what stage are they? The new non-smoking 3's?

The wheels don't look like the ones on my stage 3's. Mine don't smoke BTW

SPOautos, what turbos are these?

That is Sick...Hope it works out for you...good luck!

Hmm, ok maybe most of you guys havent seen the other thread. Bryan has redone his turbo lineup and all the new ones are due out in a month or two. Basically he's going to be selling 2 different sets of twins. He's going to have a set that has ALL new internals, everything in it is high quality aftermarket parts and its all 100% brand new so its not really like a rebuild. The only parts that are reused are the housing and they are so modified that they really arent "stock" either haha. THEN, he's going to have a upgrade version of that same turbo. Its exactly like the turbo I just explained except it has a larger compressor and turbine wheel.

Thats going to be his turbo lineup in about 2 months. They are in the build and test process now and I'm going to be maxing out a set on the dyno in about a month.

BTW - The pics are the upgrades with the larger compressor wheel. Its really hard to tell how much larger that wheel is versus the oem without seeing them side by side but trust me....they are larger lol

STEPHEN

sorry

STEPHEN

Are these a sequential set? Still has flapper actuators. Has he done anything to the manifold as well?

What are his target prices for the two products?

Yes, that set is sequential. I dont think final pricing has be totally set yet however I do know they will be a little more expensive than the old stage 3's BUT with 100% totally new internals its well worth it.

STEPHEN

From what Brian said they are $2250. I dont know if he has changed that.

Jason

I sounds like a decent price, if they are even better than the old stage 3's, ill probably be traveling down that road when I blow mine.

ok what about spool up compared to the OEM's or the stage 3's? if they can make more PSI/Flow than the 3's ill be seriously considering it. how about the exhaust manifold? anything done to it to increase flow/decrease turbulance such as smoothing out the casting or stuff like that.

oh yeah, and how does spoolup as well as boost charachteristics compare to a Ball Bearing single? its probably too early to give good answers but does anyone have an idea?

yeah...i am interested too...but it comes down to lag.
If these are parallel or laggy in generally i will end up gt35/40. kinda of want to make my decision by spring...hope there are guinea pigs outthere.

there will (assuming everything comes to plan) be numbers/charts/etc on or about March 7.

they can be run sequential or parallel, just like the old stage IIIs.

victor

Looks good!!

Damn dude, Those look super awsome YO!!!

damn, what are you doing to bryan to deserve this house call:) can he stop by my place. k

ive heard bad things about smoking, etc. with bnrs... so these do not smoke or have problems?

and yeah i really would like to see boost and hp numbers too...

its either these or a 3540 for me.

SPO auto,, what do you think of the install of the big BNR turbos in Garfinkles car . They do not smoke , and the car pulls very good . He hopes to get it tuned in March . The new AEM twin-capacltive discharge ignition was put in today .

Yea, man Garfinkles car is awsome. They look great in there. I checked out his AEM ignition when I was there, it looks pretty nice. He's supposed to be coming to B'ham the first weekend of March to have Steve tune his car. You should come down that weekend man. I think there will be quite a few people here.

Guys, for those of you concerned about smoke, that was really only one run (granted it was a large run) of turbos that BNR did and my understanding is it was caused by a defective part that he bought. Which goes back to me saying he was having to much trouble finding good replacement parts for the oem stuff and went with this new design. In addition Bryan has stood by his warrenty for everyone that had problems and from my understanding they have all been fixed. These new turbo have 100% brand new high quality cartridges in them and there shouldnt be any problems.


STEPHEN

Talk about Brians warrenty,on Garfinkles car the smokers were replaced with the trial set up with the large houseings .Brian was tring to find his fix for every one . The replacement had to cost him plenty . Brian did not ask for any more money because the first set was under warenty .David said he had to have lost money on the trial set ,as the parts are brand new . He could have just kept replacing the bad seals untill a good set turned up ( the cheap fix ) . Instead he found a better replacement .The set Garfinkle put in was very hard to install because of the bigger size . I think most customers would not be able to make them work as David did . So Brian continued working untill a solution was found that everyone can use .I would think most business would not have tried as hard to find a fix for a warrenty issue .Brian and David spent plenty just on telephone calls during this time .Yes Brian is the MAN .

Yeah, stage 3's had a bad reputation for smoking. There are some in use that do not smoke, though.
That is the reason that they are not currently available, and are being re-designed.

We're all assuming that these new ones will not have any issues:D

So, are these new ones equal to or better than the stage 3's? In terms of HP and spool up.

do you read the thread before u post?

please explain....


j

im sure he is asking for clarification. this new set is untested correct? the answer seems to be very gray.

the correct answer is...we wait and see.

larger shafts equal slower spoolup time yes?

I am excited to see the new sets hitting the dyno.


j

not really....i ahve read 5-10 times on both of the two threads that they are untested. Doesnt sound gray to me.

Yes, I did read. But like artguy said it's not too clear. A lot of people will browse this looking for them 2 facts and it would be nice if they were posted nice for less confusion. It's obvious you didn't know the answer so you had no business responding to my post. :)

bro....the answer is undefined cause they arent tested. Whats unclear about that?

I thought maybe SPO got a rough idea from Brian. I'm just saying there's no need to respond to me (or flame) if you don't know, just let it go till someone can answer it.

Well, yes, Stephen's talked to Bryan, I've talked to Bryan, a lot of us have talked to Bryan. But there is no way to tell...until we test it.

And as I said earlier, the first sets will be put on a Dyno March 7th.

So your question had already been answered, right? :)

Yes, at this point non of them have hit the dyno so there is no HP or spool numbers. If you want me to "guess" I'm going to say they should make as much as the old stage 3's and I have no idea about spool.

Garfinkle has a set in his car and they have NO smoking issues at all. Internally they are exactly the same as the ones I showed a pic of. The reason Garfinkle's were hard to fit is cause they have a larger compressor housing on them (as a test I think). The sets BNR will be selling have the stock compressor housings unless its proven via Garfinkles car that the larger housings makes a lot more power, in which case it'll prob be an extra charge for those larger housings.

As for his warrenty work, yes he lost a LOT of money on them but he stands by his word like he said he would. That about all anyone can ask for in this industry.....and from what I've seen its actually a lot to ask for cause not many RX7 spacific companies stand behind thier products like that. He took it in the ass and still kept a smile on his face about it never once complaining about warrently work.

STEPHEN

Whoa!

Brian did take it....may be not in da azz tho. :) But, that's what count when you choose who you wanna deal with.

BTW, about the smoke from the last stage 3, did BNR test some prototypes before the product was put on the market?

POM HB

ok a larger compressor housing.... im not sure i understand how that helps.... if the internals are completely the same then in which dimension is it larger? im assuming it cant be the chamber where the compressor wheel spins.... so are you just saying that the "exhaust pipe" for the compressor is larger supposedly creating more efficiant flow?

also whats the problem with these larger compressor housings? clearance? maybe this was already mentioned.. if so sorry.

lastly, can anyone comment if any "porting" is done to the cast exhaust manifolds to make them flow a little better? im sure they can be smoothed out to create less drag and less turbulance

Yes, actually I tested a set on my car and made 412rwhp on a dynojet and drove it for quite a while with no problems before he started selling them. I think what happened is when he placed a order for parts to build around 20 sets for a big group buy that particular batch of parts he ordered was bad and it ended up costing him a fortune. He has since rebuilt pretty much every one of those sets and from what I understand they are now all ok BUT he decided he didnt want to order parts from that company anymore and they are (I think) the only supplyer for our oem turbo parts.

STEPHEN

SPOautos,

That super sucks for BNR, man. Lost money and reputation. When time comes, if there is not cheap single turbo kit around, I'll have to look into this more!

POM HB

RotorMotor, to answer your questions you will have to talk to Garfinkle for details . Brian has some pictures . and info but not on every detail .The bigger intake housings should flow more air .
