BNR stage 3's???
I was just looking at rx7store and saw the new bnr stage 3's. Ive always been thinking about going with BNR's but iam wondering how much power these new guys will make. anybody know anything about em?

Hells yeahs fo shnizzle mah nizzle des double turbo be makin 400 hp at da rear wheels B. Thats runnin da hi boost at 17 psi prolly aight.
|
Check with GoodfellaFD3S he has them and started a thread about them.
|
I've got 'em too! They're great. I'm expecting just shy of 400hp at 15psi. I've just started running a little boost now and my car is very responsive. I'm running then non-seq.
|
They should be good for 400rw on pump gas with good tuning and all the bugs worked out of the car. They are great turbos, WAY more beefy internals than the stockers had. Should hold up much better to high boost.

Stephen im not sure, but i think 400rwhp on these turbos is a little high for a goal on pump gas. at least it is here in cali, we got shit gas! |

Stephen I'd realy like to know. --------------- Thanx. |

When you said "WAY more beefy internals" what do you mean by that?, what is the difference or changed to improve from stock internals? I'd realy like to know. --------------- Thanx. |
I can't say for sure on full boost. I'm still breaking in my engine. I can say that non-seq turbo lag is a bunch of BS! I start building boost pretty early and it pulls real hard for only about 7psi of boost.
I'll be posting a more in depth write up once I have my car tuned. Here are my go fast mods though: BNR Supercars built streetported engine with low compression rotors BNR Supercars stage 3 non-seq twin turbos Rotary Extreme V Mount IC with KOYO radiator and Greddy intake elbow Apexi Power FC stand alone ECU with commander and datalogit JDM Lower Intake Manifold with block off plates HKS twin power ignition amp Stock 550cc primary injectors with upgraded 1300cc secondary injectors Walbro high flow fuel pump Down pipe, resonated mid pipe, and Apexi N1 single cat back exhaust K&N twin intakes with M2 performance hard pipes Unorthodox full pulley set, removed air pump TIAL blow off valve SEC 6 puck clutch ACT lightweight flywheel (street-lite) XS Engineering high performance dual stage boost controller Taylor plug wires, running 4 BUREQP 9's |
I've got a set of Stage-3 BNR's I'm looking to sell. They do not have many miles on them. BUT you will need to use your exhaust side turbine blade on one of the turbos as mine has some chips out of the blades. This exhaust side of the BNR uses the stock shaft and blade so you will need your factory part to make these useable. In addition, the manifold has some cracks so you would want to use your exhaust side manifolds as well. I can send some pics if you are interested.

What's the turn around time on these? I tought i read somewhere that it was something like 4 months?!? I know it takes a lot of work to make these turbos, but that's crazy if it's true.

He's just got the front page up with his e-mail and phone number. |

Thanks for clarifying that, btw are you running them non-seq too? How much are they directly from Brian @ BNR, I see RX-7Store sells them for quiet bit, I'd rather save up lil more and go single, ball bearing instead... Thanks again. |

Thanks again. go to the bnr website and call the # on the site. I'm sure bryan will be happy to talk to ya :). |
these NEW bnrs are still pretty much unchartered territory. There isnt any data out at all on these. How can the manufacturer expect a person to make a purchase without thist have an data out at all. One thing that I always questioned was does the cost / value work when compared to a single. In all honsty i dont think so. Here is why : Stock twins can get you 350-365 pretty easily on a ported motor. The old bnrs got you 375-385 with one guy making 400rwhp. So thats a gain of ~ 20 rwhp with a cost of $2300. Now compare to a single...$3500 cost with power potential of 500 rwhp but most guys making in the 400s. I am a missign soemthing here? Why are u guys going upgraded twins? Enlighten me.

Allow me to enlighten you :D As I'm sure you know, peak rwhp isn't everything. A fat powerband and wide torque curve count for alot as well. If you are trying to compare stockers to the BNRs, you definitely haven't experienced them back-to-back. You're welcome to stop by my house in NJ.....my dad has stock seq twins on his R1, so the comparison you are looking for lies in my garage :). The 'sleeper' effect, whether for the street or for competition use. "gee, those look like stock twins, sure, I'll race you for $500" or "Ok, you passed visual tech for this endurance/road race/autocross event." Believe it or not, I talked to many customers at the shop from other countries looking to get a performance advantage in sanctioned spec racing. They can still be run sequentially, from the standpoint of emissions. Personally, I don't want to screw with a different dp/wg/bov/wg dump/filter/oil feed/oil return. I like the fact that the BNRs bolt right up. Oil and water cooling is a plus, also. Also, there is some data. I posted my low boost dyno #s........as per Chris at RP, I would have made ~355 rwhp at 12 psi if I dynoed later in the day once it cooled off (august texas heat). To give you a real idea of their performance potential, I ran the 40 to 140 mph sprint at 14 seconds flat repeatedly with the old style BNRs on pump gas. Go out and log a stock twin car and let me know what you get ;) take it easy man, Rich |

Go out and log a stock twin car and let me know what you get ;) take it easy man, Rich good points....i still would like to see some hard data first my man. I need more power then the 340 rwhp @ 14psi that i am currently making on the stockers. When are you going to post up some 17-18psi dyno plots? Also dont you think that Bnr should have done some dyno testing as part of their R and D, not to mention as a part of their marketing for these. I just dont get how you can develop a new product thats costs 2300 and not have any hard data to support it. Its not like BnR is new to this game either....i didnt see any data from the first sets either. I guess its simply cavet emptor and that in my mind sucks. I want to buy these but I wont lay done the cash until i see dyno sheets and i would guess many other share a similar view. I would be happy with close to 400rwhp @ 17-18 psi on stock ports. That in my mind would jusitfy the 2300 cost. |
I'll be posting my dyno sheet everywhere as soon as I get tuned. I'm only going for 15psi though but I should be knocking door of 400hp. (I don't have stock ports) My break-in is all but finished, I just got to get Steve back out here to wake my car up!
All I can say is these BNR's are SWEET and well worth the money! |
