Can I have your old turbo???

 

[prostreetdsmx1]

Ben. when i first ordered my batch of these i was told 42 lbs. as well. I mean they use the Garret setup, with out any real custom work except for the turbine housing so i might be missing something. Now i know the GT3255 is one that they custom make with the 52 trim wheel that is 76/55. so that number they can be diff on.

but aside from that they and i follow the standard garrett catalog.

I just can't find anything on PTE's site with those ratings. Are those from PTE or from a PTE reseller stretching the truth?

Those ratings are translated directly from PTE's website:

http://www.precisionte.com/products...ndor=Precision&qtype=Mitsubishi+GT+Technology

Per PTE, the GT 32, 35, and 37 (82mm) compressor wheels are rated for 520, 600 and 750 hp respectively.

I see the up to xxxhp ratings on everything but no lbs/min rating.

10 hp per 1lb/min

 

[MNGSX]

I hate that HP rating stuff...

Lb/Min or gasp a compressor map is the way to go...

HP depends on what the turbo bolts to the turbo just moves the air in and that is all I want to know.

Are you saying that the GT3255 does in fact use the larger 76mm wheel that in the old thread one member, after contacting PTE, claimed they didn't sell?

Just curious.

How can you say you follow the catalog? I posted the ratings in the catalog, and the ratings that PTE and you like to use.

I am sorry for getting in on this thread as I don't want to confuse anyone with the correct information.

 

[prostreetdsmx1]

Ben, i am actually very happy to see other turbo makers opinons on these turbos as you obvisouly have more experience in the realm of turbos that myself.

The GT3255 uses a 52 trim comp wheel that measures 55mm inducer and 76mm exducer. The "other board" did have someone saying that the 3255 was not available however it is in fact available, 2 other Vendors have comfirmed that they too have received them so i dont know how people say they are unavailble. I will have one on the Dyno in the next 1-3 weeks once the car is ready.

Sorry ben i dont undertand the question or comment.

Why are these turbos not displayed on anybody's site? I just looked at "The Speed Factor" site and not one mention of them.

Maybe we should all email PTE to start saying what wheels are in their turbos on the site to end this confusion.

They show this list:

http://www.precisionte.com/sportcompact.php

But it is still confusing which wheels are in which turbo because of the many combonations.

I believe the two main turbos being discussed are GT3251 and GT3255. On the link in your post you can see these two compressor wheel options for the GT32 as the 71 and 76mm versions of the 52trim. The '51'and '55' numbers are just the inducer sizes in mm for these two different wheels.

 

[prostreetdsmx1]

We have yet to post on the site (the speed factor) because we wanted to wait to up load video, dyno graphs and wheel pics before posting them. We should have them up on the site within the week.

as far as the turbo components, not much to them. Both turbo in question us the GT32 Turbine, both are in the Mitsu casting by PTE, avialble in a .63 or .48 AR housing. The compressor options are as stated in the previous posts. Both are 52 trim wheels. One with a 51/71 combo the other with the 55/76 wheel combo. Both are in a .60 AR t04e compressor cover. Not much to it. The proper chart to look at is the GT Turbo on the PTE site.

Martin,

Have you ever seen both of the so called .48 and .63 A/R Mitsu castings?

 

[prostreetdsmx1]

Yes sir i have, i have had quite a bit of turbo go through here. SCM and GT Series. have em all. Why do you ask?

Marti

 

[Ben K]

The reason I ask is because there were never two different housings for the Mitsu T3T4. PTE claims that you have the ability to choose between the .48 and .63 housings, however there was always only one housing.

If you ordered a .48, you received the Mitsu housing. If you ordered a .63, you received the Mitsu housing. There's only one.

I know the new GT housing is a little different, I was just curious if PTE was going to try and pull the same thing with the A/R ratios; have one housing, but call it a .48 or .63 depending on what the customer wants.

Next time you get a .48 and a .63 side by side in the GT housing, I'd like to see pics of the nozzle area and scroll area to see the difference between these two separate castings.

that sucks if they are selling the same housing. doesnt it say anything on the housing the like the garret turbos??

 

[prostreetdsmx1]

Well aint that some isht....

i must say i primarily order .63 however when i order a .48 i will take some pics, bust her open and do some measuring. i almost always have a .63 turbo instock at any given time so when i am lookin forward to a .48 coming in to test.

Now ben my questions is..... Werent you using the PTE exhaust housings for a while? I could have swore i had that conversation with some one in your organization in the past. I may be mistaken and if that is the case my apoligies on the misinformation.

Martin

 

[Ben K]

We've used PTE housings for years, and continue to use them depending on availability. Certain products we've chosen not to carry.

 

[prostreetdsmx1]

I see, Thanks for the clarification.

We are going to put this GSX back on the Dyno with a Better fmic and ARP head studs. With those installed we will push the car a little more and see what we can really get the GT3251 to make. I'll keep you updated as to when we do that and when the GT3255 goes on the Dyno.

Are you dyno testing your shop car?

If you are, it would be nice to do back to back testing with the GT3251 to the GT3255 with the same mods on the same car. For comparisons sake.

I am sure your website would get a lot of hits if you were to post a good comparison like that up.

..and throw on a SCM-50 as your "control"

BTW.. Jim at PTE quoted me 500HP for the -51 and 550 for the -55

Ben.. are you going to carry the GTs w/conventional bearings?

 

[prostreetdsmx1]

This is not being done on the shop car. Its a customers car. We are trying to work you a car that we can test the GT3255, 3251, And SCM50 on to see real world numbers. i will keep you updated.

i would like to know about AGP carryin similar products as well.

He could have been talking about 500 hp to the crank which sounds realistic with about 15-20% drivetrain loss.

What parts of PTE and FP do you have confused? You keep writing like I'm the one who is illiterate yet nobody else posted FP turbo pics

Thanks to whoever posted dynocharts and to Ben K for clarifying that new PTE housing are little different for GT turbos. Next time jdmawd you going to get smart with somebody make sure you don't sound like ass that you are

stock 7 bolt
HKS cams 64/72
DSMlink
93 octane
very consevative tuning
no timing adjustment
2 counts of knock
20psi

This one was the GT3251 with the 52trim (51mm/71mm wheel). The pulls were made on a AWD dyno.

Marti, any chance of making your customer cranking up the boost past 20?

Just to make sure, GT3251 is GT32E on PTE's website?
