Bnr k04-gt28
I guess these turbos arent really living up to their expectations
I think I know the route I'am not going now, sucks to say I think sombody wasted there money
Or... maybe there might be more room to play and might get that 360 I don't know but as of now I don't think so
But once again sorry to hear man

No worries dude. Things like this happen with early adopters of new tech. At least you guys have some numbers to base your decisions off now.
I emailed BNR to let him know whats going on. Hopefully we can get this resolved somehow.

Ok so we only have dyno numbers from the 2860 and people are jumping ship? I'm going to be posting before and after numbers. My set up right now is:
Stock k04 HPtuned to 25psi with meth, dejon charge pipes w/hks, hahn intake, zzp catless downpipe
Stock k04 HPtuned to 25psi with meth, dejon charge pipes w/hks, hahn intake, zzp catless downpipe
the fact that it's somehow choking and not gaining power from 16-22 psi just is weird to me
the 2871 was for gains
why I looked at it was go big or go home...
srsly why spend money twice.. do it once and turn the boost down.. then when you want more power (which is inevitable) just turn it up .. be more efficient
i mean i understand people not wanting to by all extra parts but really if you're gonna buy a new turbo that bolts up on the exhaust side the least you can do is have it get air in easier

We still dont have 2871 numbers, and, from what I hear, they arent so great either.
Honestly, if the advertised numbers on the 2860 werent so high I would have put money into the 2871. The fact that it was advertised at 360 is what made me get the 2860. That was my goal as far as power was concerned. I never imagined it would max out at 300whp LOL

Not me, the stock compressor K04 housing chokes it up top, I've said it numerous times.
Cubaniche, since you basically paid for an upgrade and didn't get one, maybe you can talk Brian @ BNR to give you a 2860 with upgraded compressor housing for free to save face and dyno it.

I'm glad that I'm patient and that you guys are willing to pioneer these sorts of products. You hardcore guys have saved me a lot of money. I'm still waiting on this whole Ethanol tuning thing to get some age, as well. Now I know not to bother with the BNR upgrade.

If your gonna spend cash again for a turbo upgrade wait for ZZP's, because by the time you add in BOV cost with a BNR 2871 you could have spent $350-500 more for a true bolt on with dyno results with alot more power.
NO ONE is gonna get to 400whp with the BNR2871, Sure a true GT2871 can achieve right at 400whp, the BNR is not a true GT2871, its a step lower.
If someone with a BNR 2871 wants to prove me wrong, I'm all eyes.
What is very weird is that DDM using the DDM 2871 (BNR2871) had posted a dyno of 371 rwhp on a Solstice/Sky. Either we aren't tuning these correctly or there is something majorily different between there engines and ours (or there dyno is lying). 371rwhp on a Kappa should be 380-390 fwhp on our Deltas.

For those of you who are curious, I have the 2871 and just got to the track tonight. 2.3 60', 12.9 @117mph. According to the DA calculator that would put me around 12.5 and 120mph on the east coast. I wish I had slicks because with a 1.7 60' I might even crack 11s. Anyways, I haven't dynoed it yet but when I get a chance to I will post it then.

If BNR is rating the 2860 upgrade at 360 BHP, then applying a typical 12% FWD drive train loss comes to right around 315 whp max. So actually your dyno is pretty damn close to their advertised rating. And there is something to be said about holding steady power to 7k or so if you can. So all in all you are pretty much getting what you paid for right?
As with others, i respect that you are sort of the pioneer dyno for this upgrade, and what i'm saying is not a shot at you just something to think about.

Thats assuming you do this upgrade with a tune. The power I and others made with this turbo is what I would expect if you just threw this on without a tune. We can push the K04 to make 340-350whp so I assumed that we could do the same to these and make more. But as BYT proved, even at different boost levels it still maxed out at 313.
All Im saying is that I can make this kind of HP with the stock K04. Did I get what I paid for? No, not really. Is it worth the price? No, not really. Like I said earlier. This was an untested product solely based on stock garrett GT28 flowcharts. It looks good on paper but it doesnt translate to the real world. I took a chance hoping for the best and it didnt go so well, thats just how it goes when your the first to tryout something new.

BHP is supposed to be at the wheels, with that percentage already removed. If Im not mistaking thats what BrakeHorsePower means. Second, thats assuming you do this upgrade with a tune. The power I and others made with this turbo is what I would expect if you just threw this on without a tune.

Here's a screenshot of the log from Pbass' dyno:
Here's a couple pulls overlapped:
The bright green is 16-17psi the other 2 are 22-23psi. I tried everything on this car including cam changes which did help a lil bit up top but still had a spot where it dipped. Again, I did 17 pulls with this car on the dyno, every single one looked like that with changes only before the dip lol. We changed plugs, checked the cat etc.. He is trying a catless dp now for ***** and giggles.
To be fair:
PBass showed me a dyno prior to this and it died hard up top on the stocker as well. So Im still not ruling out some other issue!

Nick, I sent ya the dyno log and chart btw. I know it probably wont change anything but, there you go 
Well, heres a pic of the log of one of the runs on the dyno. Not sure if Im really flowing 36lbs at the MAF or not.

36lbs/min with the 2860? That just strikes me as awfully low considering the stock turbo can flow that..
Me personally, Ive never hit 36 at the MAF on the stocker. Id average 32-34 peak. This one was constantly flowing 37-38. That 36 was on the dyno. Anyways, I dont know if I can even trust those numbers anyways since weve already established that it does not flow as we though it would.
