Ball bearing PTE 50 trim

Looks tempting...ball bearing PTE 50 trim complete with 1 yr warranty for $875. What do yall think? Nobody's running one of these yet right?

I saw that AGP is also offering these, albeit with the Bullseye housing and a bit more $.

Would be nice to see how these new CHRAs compare with the non-BB versions

99gst_racer · 09-29-2005, 12:40 PM

I'm think I'm going to try one. It'll be a week or two before Martin has them in stock though...

I will be going with the PTE simply because it is several hundred dollars cheaper than SBR's and AGP's.

these turbochargers look amazing folks. i am personally looking to try the 6076. I think with the BB feature it will be amazing. I already run a 60-1 and to have it with a BB cartridge could really help my 2liter out.

When Rod first told me about these i couldn't beleive it. I think i asked him like 900013 questions and everyone was followed with a fantastic answer. All they are doing is improving on an already proven design.

So everything is the same on the outside as far as fitment goes? Just maybe some waterpipe denting and fan trimming? And as far as an install kit would we just purchase the Full GT Install Kit or what? lol..just tell us all of the 900013 questions and answers you asked Rod.

Damn. I wish this was available when I got my p-trim 60-1. Right now, I get full spool on pump gas(25 psi) around 4300 rpm and race gas(30 psi) around 44-4500. Im sure the bb feature would get those down by at least a couple hundred rpm. And the price is really close to what I payed for mine.

as far as the install kit, we still use the same Garrett style kit we have always used on the SCM series but the water kit will also be needed to feed the wet bearing.

here is a pic so you can see what I'm talking about.

So, do you need to dent your water pipe, and go w/ slimline fans? Stock O2 housing?

prostreetdsmx1 · 09-29-2005, 05:53 PM

folks i don't think you are getting this all together. It is the same physical size as the SCM50 we all know and love now. You do need to dent the water pipe a little if you have a stock manifold. This can be avoided with an SBR manifold and yes it does retain the stock O2 housing.

So Martin, how does compressor surge fair with this turbo now? Would someone be able to get a T04S cover with your turbos instead of the T04E? Have you actually tested these turbos out, and if so how has spool up been on a 2.0L?

RedTurboEclipse · 09-30-2005, 02:35 AM

interesting.. i havnt even got close to max out my SCM50.. cant wait to see numbers on these things..

so i noticed that there is an option now to have the divider or not have the divider.. will there be any problems with boost creep/spike/control with having the divider and having it internally gated.. i have always thought that the reason the old SCM50s had no divider was for boost control with internal gate for that big of a turbo..

also the first turbo i installed myself was the SCM50 which wasnt too difficult.. but time comsuming because i wanted to do it right.. say i got these new turbos.. it is also watercooled correct.. is it easy to run the lines?

16g-95gsx: I don't see surge being an issue on this turbo bud. The 6031 and the 6076 are available with the S cover for an additional $75 for those who do want to go bigger.

RedTurboEclipse: The divider is normally removed to help prevent creep issues. It's really been a toss up because in all honesty i have't seen to many of these turbos have creep issues but preventative service is always a good thing. This what it looks like with the Divider cut out:

Boostn4 · 09-30-2005, 09:12 AM

I would love to be able to buy one of these. I like the BB 60-1 w/ t04s cover

.

prostreetdsmx1 · 09-30-2005, 09:17 AM

SCM6076BB with the S Cover would be scary. That is the route i will be going.

CanadianTSi · 09-30-2005, 12:25 PM

I would think these would compressor surge pretty bad, I can make my regular bearing 50 trim surge like crazy at anything over 21psi....

Removing the divider worked on my EVO III 16G, which is notorious for creep problems. Removing the divider will however, reduce the efficiency of the turbo.

Is there compressor maps available for these yet? (I'm assuming they are slightly different from the channel bearing version of the same turbo.)

EnticivEclipse · 10-01-2005, 01:56 PM

im thinking about picking one of these up since the regular scm50 was on back order.

Do you guys think a internal gate with cut divider be efficient?
or should i just get the regular scm 50 internal gate with my current mods.

A 50-trim Garrett compressor map is a 50-trim Garrett compressor map. The BB CHRA may spool up a bit quicker but overall flow characteristics would not change

Slippi84 · 10-03-2005, 06:48 AM

I was checkin out their site and I am just about set on one of the PTE BB turbos but which one do you guys think I should go with to get 450awhp on pump the 50 trim? Or is it kinda dumb not to just go straight to the biggest one for the same price and run less boost and get the same hp. I don't touch a lot of c16 or high octane gas so I need something 93 octane friendly.

What makes you think that? Correct me if I'm wrong, but as long as there are no changes in the variables (pressure ratio vs. air flow), these shouldn't have any different surge characteristics than the
