I bit the bullet and bought an PTE SCM61

[MNGSX]

Anyone who has ACTUALLY has one of these or another brand of turbo with the same combination of housings and wheels (FP, AGP etc) please chime in. Maybe with your initial experence with it as well as what it was like once you got it tuned and used to it.

 

[Mike 99GSX]

I just got one as well (BR580). No impressions yet as the car isn't finished but I do have a question. Were you told that your SCM61 was using a GT turbine wheel and not the stage 5 wheel? Mine supposedly has the GT wheel but I do not know which wheel it is(Buschur Top Secret ) Just wondering if PTE told you anything.

 

[PSI2HI]

I got one and i am not very happy w/ it. Im actually looking into selling it if anyones interested.

The turbo itself failed on me after about 600 miles. PTE's internal wastegates suck. Their open turbine housing as well suck and is very annoying, basically simulates the noise from an open downpipe.

I know PTE was having a lot of bearing failures in the get go, but it seems they've got the problem resolved as we haven't had any problems as of late.

Two questions,

1. what is open turbine housing?

2. arent PTE turbos actuall garret turbos except for the exhaust housing?

56trim GT40 Comp Wheel

TO4E housing.

I thought about getting a TO4S but Retailers have stocking turbos on sale (4E's) + I dont think I "need" it + less clearance issues.


T350 Turbine wheel.

I believe this wheel is from the original T3 and T4 line up predating the GT series.

It is also AKA the stage 5 wheel.

Two questions,

1. what is open turbine housing?

2. arent PTE turbos actuall garret turbos except for the exhaust housing?

1. Open is a bad term for it. The metal wall seperating the wg from the turbine outlet is removed. It can in some cases eliminate creep. However it prevents the switch to an 02 mounted ext gate in the future.

2. Yes all garret components except the turbine housing with the mitsu flange for the many and O2.


I don't know why there were bearing failures. All turboshops agree what the primary causes of turbo failures are. They are'nt doing anything different to a 360 thrust in a garret center cartridge than anyone else

Why do people say it's not good to get oil feed for the turbo off the cylinder head? Should I use a filter on my oil supply line to my turbo?

360 thrust get the oil from the filter bracket.

Big bushing. Tons of oil.

Garret BB turbo feed it from the head.

Ball bearing... Just enough.

Can everybody please please please not lump all the bolt on Hybrid turbos together. Some of us have worked very hard to make ours last and make the wastegates fit and work properly. To lump them all together is insulting. These are all very different turbos that only look somewhat like eachother.

Hey I have been working alot which mean$.

It also means I have only so many days to research, shop and order. It also means I need the parts to get there when I need them.

Some of us have worked very hard to make ours last and make the wastegates fit and work properly.

There was a strong chance some of you might have recieved money from some of us if you had called them back sooner.

That is'nt sarcasm but the gods honest truth about the situation!

There are three MFGs I was looking at FP, AGP, and PTE.

I'll give you a funny version of a fourth ones accronym in PM.

Also I think it may be a good buisness move to highlight the specific differences in detail on your site. Perhaps just refer to other turbos as a competitor as opposed to listing the name. Disassemble both and show split window pics of the differences. Turbo design is a specific and precise science. Show the specifics dude.

I know your comp wheels, covers and turbine wheels arent different.

So maybe you use a different 360 bearing. Show a pic of each.

Lets say you use a different turbine casting one you had made to your specifications. Show the differences and explain why you did it.

As for the gates and proper operation sometimes alot of it has more to do to what is attatched to the turbo and who installed it. What size down pipe? Std o2 housing or eliminator. As well as boost level. What type of boost control? Was it plumbed right?

If a turbo is efficent at say a given psi and the internal gate works well there and someone sets it at a fraction of that psi and the gate cant flow enough what is the real problem?

Even some 02 eliminators on the market are restrictive since they have a round wg port that is'nt port matched to the turbine housings port. Yes its a big pipe but flow slams into a ledge before it can get in there.

A lot of factors are involved.

Or returned phone calls and emails at all.

Got a question for you, I have your older 50 trim full garret kit. It feeds off the head, is this bad? Because I noticed your kits now feed off the oil filter, was there problems with the head feed?

T350 turbine wheel and the stage 5 wheel are NOT the same.

Some people have issues with big boost when turbos are fed off the head. I had two head fed PTE turbos fail on me with LOW miles.

This is news to me. What is the stage 5 wheel then?

Is it news to you that Garrett and Tnetics wheels are different? The 50 trim G and T wheels are VERY different. Same thing with the turbine wheels.

OK sorry but I did not know that 1 meant Turbonetics and 1 was Garrett. Thanks for the attitute though. It was just a question

Me to maybe not as much boost as rdrkt but I was running 25 psi and it died very quickly fed from the head.

Yeah I wouldn't mind AGP clearing this up. I just sold my full Garrett 50 trim kit to someone with the oil feed line coming from the head. I knew they changed their tune on the hybrid oil feeds but is this true for the full Garretts as well?

They use the same CHRA, so it would apply to both.

None implied or intended sorry you felt that way.

this is why pte know specifically states on thier turbos where to get the oil for. the pressure from the head isn't what the pte is designed for.

Not all turbos are created equal keep that in mind. I think AGP takes a LOT more time with their turbos and it shows in their quality. But yes the head feed vs pump feed is an issue regardless of who makes it.

 

[owndjoo]

yea, i'm the guy who just bought the 50 trim from Mike99gsx. i will be running in excess of 25psi once my 6-bolt is built. until then i'm planning on keeping it at 20psi on my stock 7bolt. i will need to know whether or not i'll need to change my lines. i just sold my braided line that went from the filter that i used on my 14b.

 

[Z1500]

Oil feed location-
99% of DSM's are get plenty of oil off the head to supply any turbo. But that 1% (usually cars with questionable rebuilt motors) will not have enough oil off the head. So just to play it safe, we now always recommend getting oil supply off the filter housing.

Kevin what do you think of devices such as the accusump turbo oiler?

Something that holds bleeds peak oil pressure on the cartridge during a shift may be a good thing indeed. It also pretty much meters out it's full 1qt on shut down.

From my point of veiw it is just a gas charged piston type accumulator and a check valve... The oil compesses a gas (nitrogen) behind a piston not a spring. But for those who don't do too much hydraulics and industrial equipment it's a speed part.

They don't have a specific diagram for their turbo specific kit but an accumulator is an accumulator. Pretend the oil source is the filter housing and the piston/rod is the turbo bearing.

Normal on throttle operation. Basically we have normal oil pressure.

You must be logged in to view this image or video.

On shut down or engine throttle roll off (or pump failure ) the oil pressure on the pump side of the check valve is below the accumulator side. So the accumulator pressurizes the other side of the system and provides oil untill it's discharged or the pressure from the pump increases. When you go from say wot to idle it will discharge untill the accumulator pressure meets the system input.

You must be logged in to view this image or video.

Oh and I'm thinking of puting a sender on the end of the accumulator so I can monitor pressure there. Main galley pressure on one guage and turbo pressure on the other.

 

[RipperXX]

Hmm, over the life of the turbo I can easily see how that could lower wear, IF there is a lubrcation issue.

This problem is typicly subject to only large turbo though correct?

Also, does anyone make a higher flow oil pump for the 4G63, I noticed as far as I know everyone use's the OEM pump?
