New Hotness

Posted 06-25-2009 at 08:42 AM by crimsondragon

If anyone knows, my BEP 50 trim died on me. Causes were overheating? Something to do with Swain Tech coating. Apparently it worked TOO WELL. Anyway, I've been running on a beater ebay 16g. I can hear it slowly dying too so time was limited. I finally got this in today. It's a Borg Warner S256 NET.

	Hotness indeed! Now put that bad boy on your car!

I JUST got one too.

I have no BS and high oil pressure, like 80 psi at 5k RPM.

I installed the turbo with no wastegate so I was running 0 boost.

Within 3 miles of driving the turbo start blowing smoke.

I took it out of the car and the oil had pushed past the hot side journals.

I'd suggest keeping an eye on it if your oil pressure is high.

I'll be lowering my oil pressure and hopefully it will stop blowing oil. If not them I'm going to try feeding it from the head.

Where do you feed from head or OFH? What is your oil pressure like?

Thanks,

Tom

	no ETT?!

	ETT is like $400 - $500 more...

Artago: I haven't installed it yet but based on my aftermarket gauge on cold, the pressure easily goes 100+ psi on WOT. Once it warms up, it drops down to around 80 on WOT. I have BS though. At least I think I do. And I got the NET because, BEP cut me some slack and sold me this turbo for $280 shipped. Helluva deal.

By the way, is this turbo a ball bearing? I noticed when I spin the shaft, it spins for a pretty good 5 seconds. I also noticed it has a bit more side to side than my old 50 trim.

No, it's a journal turbo. Apparently it's a non-Garrett bearing system so that's a plus.

How did you get it for 280? I paid 700 for mine.... and that's after my BEP 57 took a shit.

Mine has some shaft play as well... I put 3 miles on it with the wastegate open (0 boost) and it was blowning oil past the hot side journals. I'm pretty sure it's because of too much oil.

I'm going to try feeding it from the head but I don't have the proper fittings yet so I have to wait.

My oil pressure is the same as yours. I'll be lowering it today (hopefully).

	^^ feeding from the head allows higher oil pressure... correct me if i am wrong on that one. you could just port the oil relief valve on the OFH to get rid of your high pressure

	Good turbo, My friend has one on his SRT. It Runs amazing on 20 PSI. Pulled about a bus length on my Dual BB 54 Trim @ 14 PSI from a 50 Roll to 110

	I thought the Swain Tech coatings were good for power. I was just about to send some parts out to be coated. I am now rethinking this. Hope the new turbo works out

They are good for power if it's cast iron turbine housing. Apparently SS turbine housings retain heat very well. Added with the Swain Tech coating and it apparently retained too much and caused my turbo to die. It was always turbo timed and fed from the filter but it blued the shaft.

Artago: I asked them why it wasn't under warranty. They asked me who I bought it from. I said SBR. And they gave me the discount. I'm going to try to feed it from the filter regardless and see what's up. If it blows smoke I'll look into a restrictor. I'd definitely not suggest feeding a journal bearing from the head. Did you port you oil relief valve by the way? I find it weird we have similar oil pressures. My gauge could be inaccurate though so I don't know. What weight oil are you using? Also, did you have to dent the water pipe to make it fit? The compressor housing seems a lot bigger than the 50 trim.

I did a mild port of my relief valve a long long time ago but it was almost nothing and probably made very little difference. I'm experimenting with another method to relieve oil pressure. I'm compressing and heating the spring to "Squash" it. I managed to shorten it by 2 mm but it wasn't enough. The oil pressure only dropped by 5-10 psi. I'm going to try 2 more millimeters and hopefully I'll get it in the sweet spot.

I'm using a restrictor that David at BEP gave me with the turbo. Don't know what size it it though. I'm running a 4AN line with 5W30 into that restrictor.

I 've participating on Justin's thread on regarding oil return lines. I'm convinced mine is too small (just a hair over 8AN) so I'm going to fab something up using the stock return line flanges which are bigger than 10AN.

Finally, I did end up denting the water pipe a bit, but the biggest problem was the comp housing hitting the engine block where the tranny bolt is. I had to file that down a bit to make it fit. eeek.

Right now I'm just waiting on some things I need to put it back together again.

I installed it today and went for a spin. Turbo is spool happy. Spools by 2.5k and I topped out at the WG spring at 7 psi by 3k rpms. I'm also running the restrictor from Dave as well.

I have to say the customer service is pretty good but I don't think he knows his stuff too well. He lost my old 50 trim along with the Swain Tech turbine housing, he also sent me the turbo with no oil feed adapter. I had to talk to him and get him to send me the feed and drain adapters. Came in today and the bolts are the wrong ones. He gave me four 8mm bolts.

I had to dent the water pipe but no need for the engine block. It did barely fit in there. I would definitely up it up to at least -10. That's what I'm running on the drain.

	Its been debated much, but I've read that the OFH puts out higher oil pressure than the head does. I think the head just has more volume. Its out there & Justin would know. Please keep us updated on rigging things to lower the oil pressure, that would be helpful to all DSMs.

	I don't think it's been debated. I think it's been proven. Hence the general idea to feed a journal from the OFH and a ball bearing from the head.
	Posted 06-30-2009 at 11:36 PM by crimsondragon

	Agreed, I'm going to try to lower my pressure at the OFH and run a bigger return and hopefully that will do the trick. Glad to see you got your S256 running nicely. Can't wait to get mine running right. Let us know when you get it tuned, I'd like to see what your setup can do especially since mine is almost the same. Good luck, Tom

	I'm fighting a kazoo sound under boost at the moment. I think it appears over 14 psi. I'm trying to figure out if it's an exhaust leak or a boost leak. The sound is so annoying.

	Hey man. How's the BW256 NET treating you?
