TURBO!

[organicfarmer]

Well,...here it is!      TATER BUILT 62-65-BILLET EXT. TIP 'GLORIFIED WHISTLE PIG!!'      Awesome exhaust whistle!   Everybody KNOWS i have a turbo now! Bye-bye whisper-weak stocker!!

pics on!

Hav'nt done a wot run yet,...but in a ''to the hardware store drive'' i noticed the drive psi gauge is steady'er and its definetly lower then the stock turbo! Ill try to get some #ers soon. Till then you'll just have to thrash in agony!  

 

I love starting off!,.. every time i'm rewarded by that sweet turbo ''thrilling'' sound! did i mention this before?

Looks nice. I like my 62 a lot.

On the note of Drive pressure, I was "tuning" my exhaust brake.  I turned it on, and revved it up slowly until I hit ~60 psi, it was about 1800 RPM.  I looked at the tail pipe and it was hazing pretty good,  glanced at the Pyro and 1000*!!!  Goes to show that having a bunch of DP really does heat things up, Having a tight housing does get it spooled faster, but in order to make the same boost, you have to have more drive pressure, and then wastegate the extra volume.  I'm fairly impressed with my little HX35, between 6-30 psi it keeps pretty dang close to 1:1, sometimes higher, sometimes lower.

I havnt seen higher boost psi then the stocker...32psi as before. How does this compare to stock psi?? i'm running the j-06 on   sw3[100hp]   tm2[max.]  tq1[min.]  Pod85

does the j06 boost fool? if it does, how does this work?? thanks!!

What are you using for a wastegate?

[Wild and Free]

POD set @ 85% prolly doesn't help any either.

POD set @ 85% prolly doesn't help any either.

 

Based on the Dyno testing I have done there is zero difference in power output at PoD 85 thru 3K rpms. 

 

PoD is a TPS adjustment and the way Smarty effect the TPS signal it goes WOT at around 82-83% TPS on PoD 99 which means PoD 85 still gets 100% load thru at least 3K rpms but with a softer pedal and a more linear pedal as well. 

 

Even PoD 70 gets 100% power thru around 2200-2300 rpms.

the turbo still has the stock waste gate

Ok.. so time to run a little test. 

 

Go do a WOT run and watch your drive pressure gauge. If it peaks and falls or peaks and flutters the WG is opening. If it continues to rise until you let off the throttle then it isn't opening. 

 

Sometime a turbo can move more air at the same, or less, pressure. Between the airflow improvements of my cam and turbo I run quite a bit more air at 28 psi now than I did at 34 psi with the stock turbo. We are after flow and not pressure, pressure is just the byproduct.

sorry to resurect an old thread, but i have questions. as like many i don't get the numbers game with turbos.

i have a factory stock early 04. is there any way to get more air flow from my stock turbo, like a change of parts or do i need a whole new turbo? i have an S06 and will get UDC? if needed. i get rather high egt's on any of the software. i tow right now with stock tuning.

I would see what cowboy says, but I think you might be able to bolt on the 351cw compressor side to your turbo.  that will net you some more flow.

[AH64ID]

The 351 and 341 share a center section and turbine so yes you could add a 352 compressor, but the 351s run more drive pressure. 

 

The best mod would be a 351VE turbine wheel and a 351 compressor wheel. 

[Me78569]

I didn't know the ve turbine was different.  good to know.

[AH64ID]

Yes, it's a larger wheel that is much better suited for the flow of the HE351 compressor wheel.

[Me78569]

interesting.  That explains why I don't have DP issues with my setup and guys running cw's do.
