50 trim installed, finally!

[sarge]

I picked up one of the Precision turbo SCM 50 trim turbos about 2 months ago (the one rated for 450hp). Jay and matt (if you are in the carolinadsm club you have probably met these two guys) were kind enough to install my turbo on christmas day. the 50 trim replaced my frank Jr. 17c turbo. The 17c was a pretty good turbo, but I decided I wanted to go to something bigger.

Well, later on christmas day i picked the car up. Boost was set at 12psi, and it was incredibly strong there, roughly like 17-19psi on the 17c. Several days after that i messed around with the wastegate actuator arm and got the base boost level up to 15psi. 15psi on this thing is fast. About as fast as the supercharged roush stage 3 mustang. I happened to run into one on the highway about a week ago, and from 60-140mph, he had less than 2 cars on me. Later I talked to the guy and his mustang put down 328.8whp, and ran the 1/8th mile in 8.07, so I am guessing that my car is making somewhere close to 300whp. Thats just a rough guess though.

The pte 50 trim w/.63 ar is an excellent turbo. I have this in conjunction with the dejon tool 3 inch intake. I can hit full boost in 2nd gear at less than 4000rpm, and in gears 3-5, it hits full boost by about 3600-3700rpm. Very impressive for a turbo that size i think. Currently its pretty untuned. I took the SAFC settings for a big 16g equipped car and 550's and FMIC from RRE, and just added several % more fuel in the 4-7500rpm range. EGT's peak at about 850C on runs from 0-120mph. I was planning on on having the car dyno tuned at 17-18psi, but my car started to burn more oil than usual (valve stem seals are starting to go, 120k miles on them). So instead I will have the head rebuilt on my car, then probably in the summer get it dynotuned after the head rebuild. Or, if you guys think that dynotuning will still be effective on a car that has bad valve stem seals/guides i may go ahead and have it done.

I didn't see any good reviews of these turbos, so I figured I would write one. Tell me what you guys think!

I've been doing my research on turbos to upgrade to, and it comes down to the .50trim being the ultimate street trubo. A friend of mine has an AGP rs49, but with an o2dump, the internal gate creeps big time. He suggested that i look into the PTE 50trim and so far it sounds sweet. I have a ported o2 housing and 2.5" turbo back w/ a testpipe, do you think it would be dumb to opt for the internal gate, or do you think that it will creep on me? Also if someone can answer, i'm using a 255 pump, 550's, safc, and soon installing Supra SMIC, will these suporting mods + my wimpy 2.5" exhuast be enough for this massive .50 trim. What safe boost levels could i see with these mods? I would like to order a .50 trim turbo as soon as the money comes but i may have to try do some better 14b times. THanks for any help guys. Sarge, nice turbo!!

we all know 6 bolts are stronger, but still

I agree, the 7-bolt is a vastly underrated motor. The peak power figure is not what scares me, its the constant abuse that 7-bolt will take. Reliability of the 7-bolt really falls off in the repetative 400whp and up range.

There is a guy that posts on here that went 11.2@12X on a pte 50 trim on a stock 3 bolt rear The 50 trim should fit any and all your needs. However the FP3052 is barbaric on the street

 

[Gooberlog]

Sarge- the turbo you bought was the scm50 right? what a/r trim did you get, and what a/r trim would you recomend for my mods. did you buy yours from PTE or antoher vendor. i saw pte had thiers for abou $995
Anyone have feedback with SBR on their pte 50 trim from there?
thanks

i paid 800 bucks for my pte scm50. i got it from one of the carolina dsm guys that sells turbos for PTE.

as for the A/R, most everyone gets the .63 and its spools nicely

with your mods you could probably run 15psi fine, thats what i am doing right now. i have 550s also, but will get 600cc+ eventually. the supra sidemount should also be able to handle the turbo (it supported 330hp on the supra). Front mount would be better, but that is something you can do in the future.

also, i get no boost creep with the internal gate on my 50 trim. if its set on 15psi, sometimes it might hit closer to 16psi and then fall back to its set level of 15psi, but it does not hit 15psi, then creep up to 17-18psi. i have the stock O2 housing with no porting done and it seems to be working nicely

 

[Gooberlog]

Sounds good. If i do end up getting a 50trim style turbo, i will eventualy get 660's 3"exhaust, and EVNETUALY FMIC. Thanks for the input sarge. My 14b will creep from 14-19 psi and now sometimes from 18-21psi. Thanks for the help guys, keep us updated.

That is absolutely hot!!!! I can't wait to have mine in so I can play!!!!!

If I were you, I'd get the injectors exhaust, and fmic first. No use in having that power, if you can't exploit it. just my .02

 

[sarge]

i got it tuned and dynoed 2 days ago


base whp at 15psi and crappy tuning (my tuning ) was 242whp


good tuning and 20psi was 280whp on my last run


here is my 1st pull, and second to last pull

 

[FourG63 97GST]

what fmic do you have
and what downpipe?, any porting?

 

[spooling95gst]

How does the PTE 50 trim compare to the FP Green turbo? i was going to get the green turbo, but i want to know howthis turbo compares! Thanks!

i have the street imports fmic, 22x9x3, its fairly decent, but certainly not the best


i have a hks DP

no porting at all, but thats next!




i was considering porting out my 02 housing, or buying an evo 3 o2, anyone have an opinion leaning either way on that?

the pte 50 is pretty much identical to the FP green performance wise

they both flow around 700-720cfm i think, but the pte spools a tad faster

Interesting results.Please don't take this the wrong way but what kind of dyno is that?? I know some dynos read way lower than others. I just read an article where a stock evo put out like 255whp .I realize the evos run like 18psi or something stock but how can these 50 trims put out 450 engine and think I even saw where they said 500 at the engine if you can't even pull 300 with one at the wheels.

Import tuner got lke 290whp out of a 14b at like 16psi and six mods..
now even though some people say that is bull well I am still wondering
what do you have to have to get 400whp or even 370 or so out of a 50trim.I am starting to wonder if I should have bought a bigger one.

I don't even have my 50 trim on my car yet and am getting a bit worried here.What are all your other mods? You already have a big fmic? Mabye you are running out of fuel.Also what is maxium useable boost out of these 50trims with race gas? I guess if you could get 30psi out of them then that would add like another 100hp maybe at the wheels? And when they talk 450 engine is that with cams,different intake manifold ,what exactly.
I thought these 50 trims kicked big butt and took no prisoners even on pump gas.

Also I think I read another article on here where guy dynoed in the 350 to think 375 range whp with a 50 trim and he had low compression or something wrong with his engine.Have you checked compression on yours.I think you said your valve seals were shot..??

Also on agps site they have a dyno of a 50 trim car on pump gas that is at 500whp.Not sure what mods it has they are being a bit secretive but mabye since I just got an RS49 they will clue me in.I would think that one has cams,etc.But no mention of nitrous.

Again apoligize and don't want to hurt any feelings here.Just trying to understand a few things.I am a bit new to the dsm thing.Although not new to hopping up cars.

Sarge - I too have the pte50 trim, I went with a ported Evo o2 housing. The turbine housing is not ported yet though (was in a hurry). So far seems to work great. I am running 18psi with no creep or spike at all. (after i re-adjusted the wg arm, it was binding due to the clocking of the housing. Works good now though.) Nice numbers by the way.

[AL92]

Umm...sorry didn't realize you guys have 2gs of course and I am a 1g.Do 1gs put out much higher numbers with similar mods??

 

[Jasper16g]

AL92 - From what I have been told, cams and a free flowing intake will net you great results with this size turbo. According to Sarges profile, he has a stock 2g engine which doesn't breathe really well. I would say once he gets some cams, and more tunning time, he should have no problem getting into the 300's. The 500whp pump gas numbers are probably Dre's. Lottsa boost, very little timming and one hell of a tuner.

Squigs

 

[AL92]

It said DRE actually .who are they..and the car was pretty sure a 1g.
I wonder the chart says 50 trim on it but maybe that is like 57 trim or something..??? I thought 50 trims max out at 450 hp engine but still think saw 500 on some sites.
I was hopeful to see 500 at the engine with big fmic,cams and maybe a better intake manifold or am I just dreaming?? I have good fuel system I think and exhuast and evo ex man and evo 02.

 

[sarge]

it was dynoed using a dynojet dyno

yeah the turbo is rated at 450 crank hp, right now i am making 337hp at the crank


with minor things like ported 02, a 7cm gasket (to replace my too small 6cm gasket), and new and colder plugs i bet i could hit 300whp easily



the turbo probably produces 30psi or more max, i made 337 crank hp at 20psi, going from 15psi to 20psi netted me 87 crank hp (40whp),

if i had the ported pieces and cams, i would probably be making a bunch more hp, and my motor is stock and old, so no way i am gonna try to run more than 20psi on it

 

[Jasper16g]

Yeah, that is dre (andre). He has a 2g. He runs a stand alone and is one of the best tuners out there. I believe that is 500 hp to the wheels
That is also a full garrett style setup as well IIRC.

Just shows how power is in tuning. The Smithoid Eclipse made 500whp on 24psi boost ( a Red model I believe ). I would focus more on tuning than turning up the boost. Once you have 15psi maxed out, move up to 17psi and so on. Ignition timing is also very important to power and power curves. The best part about modding isn't bolting on parts, its tuning.

 

[CSSMiketsi]

Awesome set up man! I have the AGP t3/t04 50 trim w/ .48 ar. Sounds like your car being FWD is going to be a highway beast. Also I was incredibly surprised with spool, its faster than my small 16g (i had hella boost leaks though).
http://community.webshots.com/photo/77140541/113115122wHdXcO Here's my set up.

 

[2gtsifwd]

Yea i was hoping for for 300 hp when i got this turbo on and went to the dyno but i didn't. I really need to get it tuned to get more hp. But recently i put on the evo ported 02 and ported my manifold and felt a huge gain. I also bought motor mount inserts, and they definalty helped me hook up better. Next time i go to the dyno i'm going to run 20psi and get it tuned. I ran 16-17psi at the dyno(stock motor) and made 260-270 hp and 245-250 tq but it wasn't anywhere near tuned. Same mods on the t-25 i made 230 hp and 215 tq.

Hey ccsmiketsi what kind of wheels are those?

 

[AL92]

I found that andres site.Pretty interesting .The guy has gone thru a lot of stuff.Not really any info on his newest setup.

I guess 1g cars put out more than 2g with same setups it appears anyway.Since no dyno anywhere near me have to go on what you guys find out.

"i was considering porting out my 02 housing, or buying an evo 3 o2, anyone have an opinion leaning either way on that?"

Get the EVO 3 O2, unpprted it is as big as a ported stock O2 housing. Port it out as much as possible. You need to get the 50trim to breath.

I think that's pretty impressive. What kind of timing and O2 were you getting.
