PTE GT turbos

Last time I was at the track, I got 41.6lb/min at 22.5psi with the same cams as you have. Pretty close. Not too shabby out of a 16G.

I'll let you know on the 1g stuff in the fall That really is good airflow form the evo 16. Was that what you hit in 3rd gear?? I hit 43.5 in 1st but I attribiute that to some spike. Airflow is always a little higher in 1st anyways. Kjewer1 from the boards said the swap was worth 2-3lb/min. that would be nice If I can eek out 45lb/min on pump. That way with a smim and a built head I might be able to close in on the 50lb/min goal on pump. at 22 psi.

As far as the new GT stuff that pte is throwing out, David Buschur is currently testing a bunch of new turbos for the evo. Since we know this is the pte stuff i can only agree that it is the newer GT wheels. He has tried several and has not been happy with the results. he has yet to reach the br 500 numbers (good ole' 50 trim). I applaud all of the work PTE is doing with trying new combinations etc, and Martin for pushing these things to get them out there for testing. I am just one of those people who say "if it ain't broke, don't fix it." My spool up is slower than people quote for the 50 trim stuff, but i am still very happy. When i'm going balls out i don't spend a lot of time below 4200 anyways.

Yes, that was in 3rd gear at 6856RPM.

See the Gt wheels arent meant to replace or fix, the original garret wheels like the stage 3 wheel. The GT is more to give more options for tuners. For example the 50trim is an excellent turbo, descent spool up, flows really well, and has been probably the best selling turbo for the DSM's in the last couple years (makes me very happy ) but for someone who may not be into drag or wants something for say auto cross or road racing, a SCM50 wouldnt do them much good because of the spool where something like a GT30R spools up very fast and will fill their needs. We get customers of all likes, everyone wants something different. We get the people that want a turbo that will spool at like 3200-3400RPM for street use and the guy that doesnt care if it comes in at 5500 as long as he gets his 10's. So thanks to Precision and other turbo manufacturers we are able to extend those choices to you. I wouldnt put the GT30R up against the SCM50 because they are very different turbos and made to fit different tuning goals. anywho happy boostin

The previous dyno pull was made on 20 psi on 93 pump gas. Heres the new graph which was made after installing a s/x afpr and a new knock sensor. This was only at 14-15psi because of a boost leak. There is obvious improvement due to the fact that last time at this boost level the car only made 220hp. Last night I took the car out to crank up the boost again after fixing the leak. WOAH did it pull hard when I got it at 19psi!!! Then I pulled over to turn it up to 20-21 and BOOOM I blew off an intercooler pipe when the boost soared to 25psi in a heartbeat. So I just gotta work out the one pipe staying on then I'll be all set. I'll find out what kind of numbers the car makes at the track Friday @ Island Dragway and then Saturday @ the Eastcoast Shootout in Englishtown! I'll also have my datalogger running today.

whats with the old address on the dyno sheet?

 

[Ben K]

I'll make sure to change that this weekend.

that dyno actuallly makes this turbo look pretty good if you think about it he made that at 15 PSI 271whp crank it to 20psi where this thing actually really opens up your probably looking at about a 320whp dyno pull with better tunning thies no doubt it would make 350whp maybe even 400whp thats pretty damn good IMO I only want 350AWHP thats it I only want to run 20psi on 93 octane pump gas. I still think I might go with the GT3255 thought yea 1-200rpm more lag but if the GT3251 does that then the GT3255 would be much better I def see it putting down 370whp 410whp@20psi on 93 with good tuning. Anyone agree.

We've ran both a standard PTE 50 trim and the GT3251 ona stock longblock car.

Standard 50 trim went 11.28@125

GT3251 went 11.23@128 on the same tune

wow, thats impressive, can you share more details about the car the GT3251 was on? what other mods? pump or race gas? how much boost?

None of our customers with the GT3251 have gone to the track so we havent seen any feedback on that yet.

thanks

 

[PSI2HI]

Race gas.

28-30 psi flucuation.

Stock longblock,stock cams, stock intake, AFC, 2G MAS, typical bolt on's.

First off sorry about the old thread resurrection.

On to business, I just recently ran into a deal that I could not pass up on a PTE3255E with the T3 hotside. I had read through this thread previously but was wondering if anyone actually had any actual experience to show yet.

Short story--> here is what I am looking for:

1) Dyno numbers on PTE3255E T3 hotside
2) Track times with the same
3) Setup it was run on (2.0, 2.3, 2.4, cast mani, tubular, external or internal wastegate,
etc.)
4) Spool times
5) Maintenance issues if any

I appreciate all of the help guys since there is not too much info available about this particular turbo on the forums other than this thread which has been left inconclusive.

This thread is full of vendors and no one has any real life numbers or info on this turbo? Even info using the mitsu turbine housing instead of the T3 like mine would be nice. The car should be running by the end of the month and I am anxious to know what I got myself into!

 

[prostreetdsmx1]

i would think you would want to hear from us Vendors because we have tried these turbochargers before most of the public has. We have tested them side by side and installed them aswell. We can tell you what works and what doesn't. just food for thought.

Linky no worky ..though I see his info at the bottom of your Projects Page

BTW.. how light is Kevin's car?

Great times!

Were these runs back-to-back or under the same weather conditions, mods, weight, fuel, exhaust housing ..etc? Also which turbo is associated with the 415whp Dyno Sheet?
