Stephen has already said that he won't post the sheets until he gets his back up run completed. Calm down guys. And Stephen, very nice numbers bro. Looks like it's time to save up a little more than the regular stage 2 set and get the ones that you have. I have a WRX here in town that I won't be able to touch without 440rwhp or better. This sounds like it should be the ticket!! Laterz.

my apologies. just thought that i read on page seven that he found a new place that can dyno and he would be there in 10 minutes and save it to a disk. thought he was done. anyways, if this is all true i hope you are making enough for me. i will buy a set and my buddy will defiantely be buying a set.
OT: he said he had a dream about girls in a BMW beating him in his 7. i know his 7 is fast but after that it must be faster. man this guy will run away from me at sears point and laguna.

Yes, he came to Alabama to do some tuning for me and some friends. Birmingham was on his way to visit family so he stoped by.

hey Glass.
The Secret weapons have less friction on the rotating assemblies therefore eliminates a large percentage of stress on the shafts. This allows you to run more reliable boost. The more boost you run, yes, the more stress there is on the shaft. But I have eliminated most of the stress. Down the road I am developing a different thrust bearing to supply better lubrication and also some lower friction bearings to help cut down some more of the friction. Doing the designing has been a step by step process that has taken a lot of my time and it is finally working out great. A set of Secret Weapons are being sent to Rich in Texas and Steve Kan is going for 500 RWHP with these turbos. Keep your fingers crossed and hope for the best!
Merry Christmas!

Bryan, something else to think about too that I might be doing is the Nitrous Express Ntercooler kit. That was proven to add like 40rwhp on a turbo Honda. I think that might be something to consider for all the drag guys out there. I'm interested to see how much it will add on mine if/when I get it.

For anyone that doubts Bryans turbos, just ask anyone who has one (or a pair).
When Anthony (Felix Wankel) still had his TII with a worn out 160k stock port engine and a BNR stage 1 upgrade, he stayed right by my fender, and I was running a fresh BNR street port rebuild w/ solid 3" exhaust and some other goodies on a stock turbo @ 12 psi. These things are no joke. Anyone considering other options as far as turbos go needs to have their head checked!
Shortly after my new engine goes in a BNR turbo will be next in line...then all you upgraded FD guys better watch your backs
Also, glad to see your car is finally up again Stephen, and that Bryans twins are finally getting some MUCH deserved recognition. He pours his heart and soul into these things guys!
Stephen,maybe this time I can actually ride in it!

These certaily are promising.... I can't wait to see the dyno and more info.
For Now:
I could ascertain from this thread wether they are running sequentially or in parralel. If its parallel, i'll be very interested to see if or how the spool as quickly (or more quickly) than the stock twins.
Keep up the good work!

Well, the first thing that should be done is a patent on these turbos. asap. Then we need stephen to get a back up run. Then when he confirms it, I'll be sending mine in!
Couple questions though that have'nt been said.
1)Are these ran in non-seq, or seq?
2)What kinda ftlbs did it make on the dyno?
3)At what rpms did you make your peak hp, and ftlbs or torque at?
Please don't sidestep the questions, like when Rikki did with his 360+hp run.

Congrats Stephen and Bryan!
Sounds like someone may have stumbled onto something. If these turbos do what has been said(and I'm not doubting it) then they will really put BNR on the map not that you're not highly regarded already though.
I'll be interested to take a look at the dyno sheets too.

I agree with pp13bnos too, try to be as up front and honest about what mods were done to the car/motor without getting too much into the secrets of the turbos. I can respect your secret if you have one as lots of other turbo builders keep their turbo internals secrets as well.

I believe they're talking 2k-ish. Sounds worth it if they perform as we all hope.
Regardless of wether they're "worth" more, i bet they'll actually make more money if they keep around that price.... you see how many folks have bought the M2 set... like two or so.
Once the price creeps anywhere near that of a single turbo kit, folks will be crawling out of the woodwork on this forum to say "why wouldn't you just simplify and go single turbo?"

Also, for the non believers Steve Kan of Gotham Racing tuned my car and got these numbers......then told Brian he wanted a set for his CYM.
I'm going in the next week or so to another dyno just for a back up.

. Now I have to mail my midpipe back to Texas so that I can ditch my highflow and airpump. And to think that all the domestic boys were afraid of me *before*

Not only that, but you get some real customer service, and a real warranty.
We all know how fun it can be to get GReddy to send you parts, or help when something goes wrong.
Why would you want to run a single @10 psi???

Bryan,
Congrats on the great preliminary numbers, anxious to see them backed up and some sheets posted. Keep up the good work, I know what it's like to pour your heart and soul into something!!!

Vosko has a binary right foot, either nothing, or WOT, so he has to turn his boost down...lol...he has not learned what feathering any of the pedals means yet...LOL

Baddog, I've been going over the fuel inj duty cycle issue. If you use the 40psi of fuel pressure it does seem to be low but I've been reading Lightening in a world or thunder and it says the stock fuel pressure is 37lbs at 0psi of boost and goes up 1lbs for 1psi. My fuel pressure reg is tied to the manifold just like my gauge so I would use my gauge boost reading (instead of the pfc boost reading), which was 17pri of boost. This would come to 37 + 17 = 54psi of fuel pressure
Using all this info on Max Coopers site here is what I came up with......
BSFC of .60
fuel press of 54lbs
pri of 875 (RC flowed them at 875's instead of 850)
sec of 1205 (RC flowed)
75% inj duty cycle
467 RWHP
I guess the issue is if Lighening in a World of Thunder is correct about the fuel pressure, I'd have to assume it is since its tied into the manifold pressure and the numbers work out perfect.
