Ball bearing PTE 50 trim

[Coup D E'Tat]

I have the pte 3431 BB 57trim. Last one that slowboy had actually. So far am loving the turbo. I had broke a turbine blade on my bullseye 50trim so i need a new turbo quick and everyone was out of the 60trim. Talked to slowboy and they told me go for the 57 or the gt12 . They told me the latest i would spool with this turbo would be 4400 but since i am fwd i didn't really care about it that much. Let me tell you something am getting full boost at 3800 same as my t04b 50trim. Right now am only boosting 14psi since am waiting on my oil line filter kit from FP to reduce the oil pressure more(no balance shafts). I'll post pics later of the setup. At 14 psi it feels like the turbo is pulling as hard as my 50trim did on 18-20psi i can't wait to turn it up more

You're pulling it from the head, or the filter housing? When/if I get a BB setup, I think going off of the head with an inline filter would be the way to go.

i wanna see sum numbers and track times from you guys!!

The warranty from PTE is voided if you don't run it from the filter housing. At least that's what the papers that came with mine said!

Do they come with a restrictor, or is it just not needed because of design, or what?

Comes with a restrictor

I'll have some dyno numbers in a week or two. Of course we are at altitude so our uncorrected numbers will be low, but I can get a comparison graph between my car and my brothers. (both with pte 50 trims)

We now have some 50 trim BB CHRA's in stock and ready to ship. Buy yourself a christmas gift

After these are gone it may be another good wait to get more in.

Thanks,

Matt - Congrats on getting that turbo installed. 13 psi by 3K really sounds appealing. Thats much quicker than my channel bearing Garrett. Any signs of surge? You'll have to give me a ride in your car next time I head that way. I'm very interested in how it compares to my channel bearing 50-trim. Keep us posted.

As posted before, it does come with the restrictor in place. The only problem with that is clearance between the 90* bend in the oil feed line and the stock exhaust manifold. Since the SBR manifolds allow a bit more space between the manifold and the turbo for larger compressor housings, this could fix the problem. I've got a tube 90* as Paul didn't have any of the cast 90's in stock. Its possible the cast fittings would fit.

Paul - I have not had any surge issues, and have gone up to about 22 lbs on it. The internal gate is a temporary band-aid until I get my external going, so it hits the stock 13ish psi and will creep up to 22. Keep this in mind should you choose to go with an internal gate that is not externally dumped.

Did you run that turbo at the dyno day?

No, I still had the Evo III at 17psi at that time. I just got the 50 goin about 2 days ago.

If my oil line setup on my RS60T worked, I'm sure the restrictor would fit. If not, I'd figure out a way to put it elsewhere for clearance.

Any word on the 60-1/T31 surge issues from anyone?

 

[RavenX]

Yeah i plan on moving that restrictor that comes with the turbo. My oil feed line is the 90 degree one and although it fits theres like less than half an inch between the 90 degree bend and the evo manifold which is what i have. Although i have not had any problems how it is i would rather have some peace of mind. Am just surprised that i have to get another restrictor for the turbo since theres still too much pressure from the oil filter housing. Am getting a little blow by at idle but that will be fixed soon enough

Do you think a boost controller would help it with creeping?

 

[blackGSX2g]

Even the best manual or electronic boost controller cannot release excess exhaust pressure that causes creep. Its possible that by turning up the boost with one of these devices, you can keep boost high enough to cover up the problem (as I found with my old EVO III).

I will hook up my MBC and set it to around 18-20psi and post back. The roads are covered with snow at the moment and I doubt they will be cleared until tomorrow. Not the kind of weather to be doing heavy boosting.

I think in this situation the best rememdy would be an external gate for more complete boost control.

Good info here. Seriously helping me narrow down my upgrade from the 16g.

Any idea on the spool difference between the 3431 and the 5031? (Vendors?)

I know RavenX said he gets 14 psi by 3800 on the 3431 but I really wouldn't consider that "full Spool". I'm thinking more like 22-25 psi.

 

[AutoMods]

Raven and BlackGSX are both of you routing back into the exhaust?

You guys running the undivided turbine housings?

Just tried it tonight 22psi by 4-4100rpms

No mine came with the divided turbine housing. It didn't really matter to me since i have a external gate. However tonight when i ran it on 22psi i got creep to 23-24psi for half a second and then went back down to 22psi and stayed there till redline. I'll be testing it more once i figure out my knock problems but so far this turbo has impressed me alot. Another thing to note it spools by at that rpm but you don't really get kicked in your seat until about 4500rpm which was something i noticed most likely since this turbo is more top end than midrange.

How is this 57 trim for traction on the fwd? Did you used to have an evoIII how do the two compare? I was thinking about upgrading to the 50 or 57 trim in the future. Does the delayed boost help traction at all or once it spools does it hit as hard as the evoIII and spin the same just at a higher rpm?

I went from the evoIII to the vtrim then the 50trim and now finally the 57. You can't really compare the two. The evoIII is a great turbo for midrange power so is the 50trim. It pretty much just spins ive only managed to chirp them in 2nd gear at 20psi since i have brand new tires but once they start wearing down i am just going to be spinning. Your going to be spinning more with the 50 or 57 but thats to be expected. I've grown accustomed to the spinning so am not that worried on what i go with because either way its going to spin.

I am running the 38mm internal gate with a 3" RNR o2 eliminator exhaust. The turbine housing still has the divider.

 

[blackGSX2g]

I got most of the bugs worked out of the turbo set-up and threw down a rough tune. I am now hitting 20psi by 3300 RPM by flooring it in 5th gear starting at about 2500 RPM. I feel that with more tuning, I can bring that down even more. I've got a few post MAF boost leaks to fix so that I can stop running really rich, but the turbo pulls like crazy past 15-18psi.

Nice, good spool there. Am spooling the bb 57trim by 3800 in 5th gear at 20psi thing pulls like a rocket up top. How much airflow are flowing at that psi?

5th gears pulls aren't very accurate. When do you see 20 psi on a 3rd gear pull?

I just like using 5th gear pulls to compare spoolup to the other turbos I have run on my car as it slows everything down enough for me to watch the tach, boost, timing, knock, etc. I was paying more attention to the road and my laptop during the lower gears to watch the boost gauge and the tach. I'll make some more runs and see what I come up with.
