BNR stage 3 turbo oil flow/seal problems

Just got back in town and I have started to hear about oil flow/seal problems with the stage 3s.

I tried to do a search but came up short. Would some one be so kind as to bring me up to speed and enlighten me?

I have yet to install my set so I am wondeing if there is a fix yet?

Looks like it's hit or miss. I talked to Bryan and he said "they're still a work in progress", that's why there's problems with oil leaks. I'm gonna go with the Stage2s instead.

according to Bryan, the power potential is the same since it's the same compressor wheels. The difference is in the longevity.

Is everyone currently running the BNR's using an oil restrictor? Tom

Theres a guy here in the Dallas area I know that has the stage 3s. He's been having some oil leak problems him self too. I've heard though that the 3s can have oil leak probs. alot.

the leak is passing through the seal and getting hot. . burning. . . and smoking a lot. the fix is out there. . . i hope. there is a local guy (david garfinkle) that is STILL waiting on his set. he has to be ready for a dyno session at the end of the month or at the end of september. i would assume bryan is working very, very hard to get those things right so that david will be there "with" the stage 3's.

BTW, im a poet and didnt know it. hahaha.

That's too bad to hear. I was hoping to get some stage 3's here soon but I guess I'll wait until my stockers go.

That should be before the next oil change probably

the smoking is only on certain cars. . . it may be the pcv or something. im not sure why its only on certain cars. david got the pills that everyone else got and his still smoked. he put an NA exhaust manifold on his car to check to see if it was his motor, but it didnt smoke when he did that. i hope this all clears up soon.

paul

i hope the guys that have no smoke are getting ENOUGH oil. . .

I had the chance to talk to Bryan at the recent B'Ham rotary meet. Great guy and knows his stuff. Paraphasing, so I hope he chimes in, but the dynamic seals don't seal as well as the older style carbon seals because they are missing...umm, a seal the carbon's do have. Hopefully Bryan can do a better job than that about what makes up a dynamic sealed turbo and the carbon sealed turbo, since that's what is the difference and is contributing to the oil blowby.

I ALMOST had had KDR send my stage 2s back since Bryan said he'd tear them apart and make them 3s for not charge but decided against it and it worked out perfect. I never had a hint of smoke at anytime (even right after the install)

I know the power potential is the same since I made 380 rwhp running seq at 15 psi with a HF cat - add a midpipe and 17 psi and I'd be right at Stephen's numbers of 412 rwhp or so.

I hope Bryan get everything worked out - great guy with a vast knowledge of turbos. It will be interesting to see how long the 2s last on my old car - I'm sure quite a while since they ran flawless for me. Still too early to tell but the 2s seem to be the best bargain out there (especially running seq)

That's about what I'm looking for, 380-400HP running Seq. What other mods did you add on to get to this?

I have the stage 3's and am leaking oil badly. But I am not sure if it is from the seals or if it is from not having an oil catch can to stop it from going into the intake track.

who tuned your car for that much power at 15psi...thats nice!

Here's Brian's exact response to the oil leak problem of the Stage 3s...

What is happening with the stage 3's is they are getting fed too much oil volume and pressure. The turbos must see anywhere from 35-55 psi of oil pressure. What is happening is they are seeing full engine oil pressure and they aren't draining efficiently. Another possibility that can be giving me problems with improper oiling is there is a ring gap that see pressure from the compressor housing, therefore pressurizing the crankcase, not allowing them to drain efficiently. I have stopped about 90 of my smoking in my car, but I need to step it down another notch on the oil restriction. I want to do it on my car that way I know it will work. It has worked so far, but I want to take every precaution necissary to make everything right for each and ever customer.

The stage 2's are the exact same turbos as the stage 3's but the stage 2 has carbon seals instead of dynamic seals. Its not really a downgrade, it can still make as much power... The stage 3's are a work in progress so if you are in a hurry to get some upgraded turbos, I have had nothing but good luck with the stage 2's. Call me if you have any questions.

I have the 2's. Plenty of power...no problems...i suggest staying sequential though.

this is the same issue most turbos have, people slap them on and the turbos are seeing too much oil pressure at higher RPMs and boost levels. generally i tune oil feed based off how the engine is reacting, how much oil consumption it is using and by smoke under boost. an easy way to fix it is by tapping and threading in a carburetor jet, working your way from largest to smallest and tuning the consumption you are having, if by simply adding a restrictor it made no change then you probably have an engine internal oil seal issue, starving the turbos for oil obviously is something you want to avoid.

edelbrock main jets work well as a restrictor and usually fit snug in the feed line with a threading tool.

i've even seen some reputable shops put together setups that billow smoke at high RPM and high boost loads, no restrictors.
