I am curious about these and if you guys are running stock ECU or PFC.....

Can you share with me what your tuning experiences has been like?

 

I'd like to know as well. I'm prolly going to get some of these bad boys soon. Supposedly ~420 to the ground at 17 psi, and they're good up until 20psi.

Dave at KD Rotary emailed me yesterday saying that he has a set awaiting installation on a customer's car....no dyno results yet of course, but he said he was *highly* impressed by the quality of work and customer service.

 

Wrong forum slick

 

What are u talking about grease?

no point in posting this on single turbo section nor the PFC section.

this is all about upgraded SS turbos.........

 

Yeah, I heard that it should pump out 400rwhp on a stock engine with all the proper upgrades.......... so I am just curious.....

 

Ohhhh, look guys! We got a new 3rd Gen Mod!

Jim's gonna be pissed he didn't get the job

 

lol........ resource is already assuming ownership..........

 

I believe Kwikrx7 has the BNR turbos.

 

Yep, kwikrx7 should have the stage2

I have the stage 1. Currently pegged to 10psi.
I got boost sequence of 10-7-10
I have to open the HomeDepot wastegate and precontrol valves more too. WHY? Because I am running stock ECU, while PowerFC is waiting on the shelf.
The spool up quick, I cannot believe how fast they spool.
I am still scared to punch the throthle until now. I am afraid it will go out of control, or blew the engine, because of the ECU

What is the difference between Stage I and Stage 2 BNR turbos?

 

kwik seemed to feel that they were a bit too laggy...at least his set was...non seq of course.

where are ya kwik??

stage 1 is just the secondary turbo increased in compressor size.

satge 2 is both.

 

they lag another 200 - 300 rpms but has very strong high end power.

 

Where can I find info on buying the BNR stage 2 upgraded units? And what is the approximate cost of them? I was thinking of running a T-04E but these sound nice as well. We'll see I guess.

Kwik, hurry up and post so I can hear what you think about them. Much appreciated.

These turbos seem to be a good deal and the price is surely right. I may have to scrap my idea for the T-04E and just go with these. I'm gonna try and find some more people that have them or have knowledge of them first though. Thanx everybody.

 

So with these turbos, everything is the same as stock but they just give you new compressor wheels? Or are they like the M2 turbos where the turbos are new. Also how do these compare to the M2 turbos?

 

Here are the versions:

Standard rebuilt with clipped turbos.

Stage 1 with one of the turbos bigger. Great for daily beater and with a strong 2nd turbo kick. No increase in lag.

Stage 2.... usually done non-sequential, but you can keep sequential and it increases lage slightly by about 200 - 300 rpms. It pushes about 1000cfm and should be good for 400rwhp with stock motor and all the good bolt ons at 15psi. There will be a post about this in the next few weeks by at least one of the guys with stage 2.

Essentially stage 2 gives you T66 HP figures without the lag..........

 

I'll believe it when I see it.

 

glassman you crack me up.


but i see why you feel that way.



PS...i think barry found them to be very very laggy in non seq....

be sure you upgrade the shafts if you do the wheels...the old school way of just larger wheels causes the shafts to snap.

There is no secret sauce when it comes to performance.
With a turbo car, there is a trade off between lag and overall power. Who wouldn' want to get 600 rwhp @ 10 psi and full boost before 2,000 rpm's?
A small turbo will spool more quickly, but it also runs out of air sooner as well as produces less peak power then a bigger unit.
While a stock sequential twin turbo FD is loads of fun, you hit a ceiling performance wise.
These cars have been around for awhile now, everyone has tried upgrading the stockers in some form or another. At this point they have all failed, I have yet to see a sheet or track time from any of these modified turbos wow me.
I agree lag sucks, but if you want performance its a trade off.
Ask the guys with singles and they will tell you the lag is over rated. There are other ways around lag, from BB turbos, coating housings, different gearing, ECU's with no-lag functions, changing your driving style to match RPM's etc...

Bottom line is, if I can make 450 rwhp out of a set of twins that cost me $1,500.00 and get full spool at 3,1000 rpm's sign me up.
I'll take a few sets.
I have yet to see any proof of this.

 

i think the bnr turbos are less laggy because they can be run in sequential mode.

I feel the same way as glass man. If the BNR's make that much porformance, have not much lag, and are that cheap then i will definately get them. But until i see dyno's and the reliabilty of them i will stay away.

 

Are you smoking crack?

 

ok, here's the deal right now. The set I sent Bryan to upgrade ended up having a cracked center housing (not Bryan's fault, I just sent Bryan a $200 set of crap ) Anyway I dynoed with them non-seq. and pulled down 261 rwhp by 5K rpms at about 9 lbs of boost - but most of the boost was leaking past the wastegate. After 5K rpms the power just started to drop. Even though the turbos are in great condition, Bryan said he'd gladly take everything apart and fix the housing (great customer service) If I put down that much hp at 5K rpms imagine what kind of power I could have gotten if the housing wasn't cracked at 15 psi........I also have a hi-flo cat.

I know there's some doubters, but Bryan has my turbos now and should be back to KDR in another week. I'm set back up sequential and will dyno at 15 psi. The wheels are huge..as big as the stock snails will hold and the workmanship is second to none. For $1650, these turbos will perform like a medium sized single turbo without the lag unless setup non-seq. I can't really comment on the lag with non-seq as the cracked housing really inhibited the spooling time. It wouldn't go past 9-9.5 psi and we had the wastegate pinched off and all the boost leaked out.

Just a LITTLE more time on this guys....I'd even be happy with 370-380 rwhp at 15 psi with a hi-flo cat. Hoping for more.
