Ball bearing PTE 50 trim

[scottsee]

I belw my stock t-25 last month. I've been looking at 50trims, but I'm affrade it might be to much for my stock 150psi 7bolt.

If you mean because of the concern about crankwalk, don't worry about it too much. If you're gonna get it, you're gonna get it.

My 50-trim (7cm housing) has no surge issues whatsoever running as high as 24psi on the street with an OEM BOV. Then again I dont' see 20psi until ~4100RPM with my FP2 cams

Thats why mine surges, stock cams. I turned down the gain on my boost ccontroller to slow the spool slightly and that fixed the problem.

i have to say you are the first person that has said anything about a surging issue on an SCM50. I have never had a customer complain or bring that issue to my attention.

Just curious are these ceramic ball bearings or a copy of a garret GT twin ball bearings?

They are neither, they ARE GARRET TWIN BALL BEARING TURBOS.

From AGP's Site

Garrett Performance Products has released a dual ball bearing 50 trim turbocharger that gives you all the same features as the 50 trim we've become to love, now with quicker spoolup. Dual steel ball bearings provide less rotational friction that will allow for quicker initial spoolup, and better transient response. If you want everything, get the 50 trim Ball Bearing.

99_gstracer, which version of the PTE bb turbo did you get? Please post a review later. Anyone else have the PTE version or AGP bb turbo?

It would be really nice if a vendor of these turbos posted a dyno with spool characteristics on this ball bearing turbo. We know what kind of power is possible from the 50 trim, so the only factor in buying one is how much better is the spool and transient response. If I could get full boost by 3400 instead of 3800 then I think it would be worth it, and I would buy one this week. Without some solid info I just can't justify the purchase. I would even be willing to use my car as the guinea pig for the turbo if I got it at half price(wishful thinking, I know)since it would be the perfect test bed to max it out. Anyway, just hoping for a response with some numbers from a vendor.

My brother bought one, he should have it some time this week. I will post a comparison to my car (standard PTE 50 trim, internal gate), even though our setups are slightly different.

I feel the same way. I really want it but if it doesn't spool less than 3800 like my 50trim theres no point. I am just itching to get it though

I agree I would love to see some dyno #'s or compressor maps of this bad boy.

just curious why you fwd's want a bb turbo.. i mean traction is bad enough.. unless your running slicks a lot.

Or drag radials . Traction is bad enough as it is so why not make it spool a bit quicker. Besides its fun as it is passing people while spinning tire

 

[Generation X]

Traction is going to be bad in a fwd with any turbo upgrade.

 

[blackGSX2g]

Any updates on spool-up characteristics on this turbo? I'm very interested to hear how it turns out.

The comp. map is the same as a non BB 50 trim.

 

[UPGRADED2G]

even with my current financial situation, I would consider it!!!
did i hear someone say "groupbuy"

Lets have some numbers already. This reminds me of the TO4B vtrim thread....which i have on my car. Does anyone see a pattern here....

Hey thanks for the info man.

Yes, people blaming their lack of performance on their current turbo then buying into the hype and promise of a "new and improved" one instead of actually spending the time to properly tune their current setup

Not pointing the finger at anyone in particular as I myself have been down this road and have been guilty of same. Just want to keep this thread REAL and not another new turbo HYPE thread that always seems to materialize around Christmas time

 

[shleppy]

However with this turbo thats not the case at all, since there are absolutely no gains in power to be had by switching to it over the regular 50trim. The only two reasons I can see for getting it would be faster spool and better longevity compared to the regular pte 50 trim.

 

[Slowboy]

We finally got our first shipment of 10 pieces, we have all the different PN's in stock...

They look fantastic!

MGH

 

[shleppy]

Whats your introductory pricing going to be? I'm between this turbo and the gt3076r, and what I'm really concerned about is spool and reliability, not total power production. Based on these criteria which do you think would be a better choice?

 

[DSM90AWD]

I'll buy that any BB turbo should have slightly better spool off-boost, but remember in a race that difference is practically nil (unless you granny shift pausing btw gears).

As for longevity, I've never seen a study which said a BB CHRA lasted any longer than a conventional bearing CHRA, nor has anyone tested this new CHRA (or even ran it on a DSM yet) so saying it will last longer is pure speculation

With many threads of oil seal blowout on PTEs with conventional CHRAs, I hope one of the vendors will offer definitive information as to the correct oil lines/restrictors to uses with this new BB CHRA after it has been actually tested firsthand

I can tell your from talking with Mark from SBR and The Speed Factor these things look sweetttt. I am actually getting myself a 60-1 BB but will not disclose any more info right now cause there aren't that many right now But I'm tellin you I will have this things up and running real soon with some real world numbers for you guys so we can stop all this premature turbo talk.
