What PTE turbo is this

[myturbo]

is there numbers on my turbo that will let me know what it is i was told it was a custom 57 trim but all the pte 57 trims ive seen look way littleer it says a/r 60 it has a 3.5 inch inlet

[kahl23]

There's nothing I see that would indicate what model turbo it is. All those numbers say is that the compressor cover has an A/R of .60. If you want to know for sure what turbo it is take off the compressor cover and measure the inducer and exducer size and look it up, that would tell you for sure what it is.

what does the a/r mean and do i measure the small or big part of the wheels

and does the bigger a/r number better also how much power will pte 780 cc injectors hold

Your turbo has an "E" compressor cover....it could have a 46 trim, 50 trim, 54 trim, 57 trim, or 60 trim compressor wheel; most likely mated to a T31 (Stage 3) Garrett turbine.

I'm hoping the turbine housing isn't the PTE "undivided" style...that would sound horrible with your o2 dump.

how much power will the 57 hold im tryn to get 600 awhp on 25-35 psi how much power will pte 780cc injectors be able to handle

what lets you no its a E and its mitsu flanges with diveded dump and waste and the o2 is waste g side is open dump it sounds evil im only running 22psi for now do you no where to get a o2 dump with waste gate block off i going to a externial thanks your helping me understand this

Its a mitsu housing. So its a SCM 50 series by the looks of it. No water lines, so its not ball bearing, so its not a 50XX-R. So its probably, if i had to guess, a SCM-5031E.
Just checked on extremepsi, and I couldn't find a .60 AR turbo?

You know its a E cover by looking at turbos all day. The S and SP cover are 4 inch in, 2.5 inch out. Yours is not a 4 inch in.

no its 3.5 in and 3 out a local dsm shop said it was a custum pte 57 trim turbo and the guy that bought it threw them said it costed about $ 2,000

thats what i was told anyways by the shop and seller how much power if its a 57 trim will it hold and pte 780 cc injectors

I don't know of a PTE turbo that uses a "B" cover, and the "S" cover has a 4" inlet and a 2.5" outlet, which yours does not have. Yours is the "E" cover, using a 3" inlet and a 2" outlet. Bust out a tape if you don't believe me.

I hate to be the bearer of bad news, but you're not making 600whp on an internally-gated turbo....expecially if it's a 57-trim. I've heard that compressor wheel just doesn't work well with our cars. Lots of lag, not enough flow potential to make the lag worth it.

$2000 for an internally-gated journal-bearing Garrett wannabe? WTF

I don't have 600 that's what I'm wanting I was told it was 3.5/3 I will measure it tomorrow and I had 22psi at 2700 rpm and I was told it was custom made.

How much power will 780 cc inj hold

I bought the car I thought it would be fast enough that only lasted a week.

 

[VETTE_50_TH]

3.5/3, ha. They lied there asses off or don't know how to measure. There is no way thats 3 inch out. You dont get those until you have gt4X or have turbos that flow well over 100 lbs/min. NO WAY.

James

 

[JusMX141]

If I had a dollar for every "custom made" turbo I've heard of....

You can't judge the power potential of 780's combined with a turbo you know nothing about. The most I can tell you is that the internal gate will never allow you to make enough boost to overrun your 780's.

If I had to guess- that turbo, 22psi, rough tune = 340whp.

 

[VETTE_50_TH]

780 can get you into the 400's. If you can tune well enough. You will need a shitton of boost, probably some meth as well to pull it off. I have 880's i can sell you if you want them. Brand new PTE 880's. PM me if you're interested.

yes they said it was tuned mostly for street and made 341 awhp on 16 psi i persinally did not belive that much power on 16 psi and when i cot the car the turbo and the manifold was loose as sh*t and the cluch did not fully ingage

Most PTE turbos have the model number engraved on the compressor housing , right where the coupler goes.

Just checked on extremepsi,

and i couldnt find a .60 AR turbo?


James

ived tried proally 60 sites and did not find a .60 A/R

 

[kahl23]

That's a .60 A/R on the compressor side, not the turbine side.

 

[myturbo]

no one said it was the turbine side i now what side it is

 

[booostedGSX]

i dont have 600 thats what im wanting i was told it was 3.5/3 i will measure it tomorrow and i had 22psi at 2700 rpm
and i was told it was custom made

WTF Am i the only one who thinks 22 psi at 2700 sounds a little out of whack?

 

[jjgrizz73]

WTF Am i the only one who thinks 22 psi at 2700 sounds a little out of whack?

haha I wish my evoIII would spool that quick damn...

 

[kraka]

no one said it was the turbine side i now what side it is

Then what's the problem? All Garrett/PTE turbo's with an "E" cover have a .60a/r housing?

You got ripped off, sorry to say. You still have a great setup, don't get me wrong, but you do not have a $2000 custom turbo.

Oh, and if it is a legitimate PTE 57trim, then you do NOT make 22psi before 3000rpm!

oh sorry i meant 22psi at about 3700 and the car 1-2 gear would snap sideways when it hit 22psi and then one day i cot traction and broke tranny now i got a tre stage 3 trans

 

[myturbo]

kahl23 just watched youre vid your car is pretty evil not trying to be judge mental but your car would run about 11.500 if you shifted faster love your car bro

 

[DSM-sagacious]

805DSM is right. If its a precision turbo you have the model scratched in around the outlet of the compressor. I also agree that its probably a 50trim maxing in the 480-490hp range per precisions ratings.

 

[turboglenn]

that's a relatively nice spool for a garrett to4e 57 trim turboi. I have the same one, but it's a full garrett build. The 57 trim compressor map shows enough airflow to support 510 HP, but you'll never get near that with it on a 4g63. MY "overinflated" best numbers on a dynojet were 468/429 running it maxed out on C16 and adding the extra fuel my 550's didn't have by using a nitrouse fuel solenoid and fogger nozzle. I would say "real world" figures of what i made were probably about 430hp/390ft lbs, as that was teh best i can make now on e85 with larger cams and a lot of little changes. My best "pump gas tune" brought me 332hp/312 Ft/lbs at 20psi... Run it up to 30-32 and you might get to the 450 range with a good amount of supporting mods, a good tune and having EVERYTHING as free flowing as you can get it. For 600 horses you're going to need to step up big time on the compressor and turbine wheels.

And the above is probably true although i've never seen those kinda numbers ona 50trim they do work a lot better with our motors. The 57 trim came and went in the DSM workd. A few of us put them on, got dissapointed and changed turbos.

you should maybe look into selling it and using tha money towards an HX40,gt42r, or one of teh borg warner S series turbos with an extended tip compressor wheel..they are teh cat's meow!
