looks stock

 

nope thats a T4 wheel on the stock Compessor housing
and the inlet has been machined

You can grab a T4 machine the back housing and fit the whole T4

I.E T4 CHRA-P trim turbine wheel/ and front assembly

good numbers BTW

 

kabooski how can you tell? How many blades does the stock compressor wheel have? I tried looking for to4b/to4e style compressor wheels but didn't find any great pics

 

The T4 wheel has a more of a angle to the blades
as seen in the 1st pic

I have a T4 wheel I bought new on ebay a while back
its just like that one

 

The inlet that you said has been machined, was ported and knife-edged by me. The housing was completely stock when off. Even looking at the wheel w/o the housing on and comparing to another stock turbo I had, I could not tell any differences.

 

you can take the comp cover off and with a DIGITAL CALIPER check the diffrenses

 

damn, if it is a T4 wheel, then I'm not gonna feel so good about my numbers...

 

Turbo timmy has a stand alone with a greddy V spec FMIC and a upgraded wheel and could not break the 300 number so don't feel bad (280'ish or less If I recall)

The small Turbine wheel is what is holding you back

 

I really wanna do another dyno run in 4th now, I think I could prolly put down near 260 with the boost holding.

 

not a great great pic. i think yahoo automatically made it smaller.

 

Even if it is a t4 style wheel without measuring the size of the wheel it could be just a s trim or t5/t6. I think the biggest wheel that can actually fit in the stock compressor housing is a v-trim.

There are quite a few people putting down 300rwhp with the stock turbine...of course most are using h-trim or 60-1 copmressor wheels.

That being said...we all know full t04 turbo's are a lot more efficient and will make a lot more power than hybrids.

 

Oh, you're assuming eveything is tuned to best efficiency?

Uh, someone is not tuning right.
I've seen comp upgrades break 300 to the wheels with the stock turbine section...

I bet BNR would object also.

Here is my Hybrid
I'll be running for now since I sold my T-66
except I will not be using that stock CHRA
I have a another stock turbine housing
P trim ready that will accept a full T4 CHRA

I'm going to attempt to be the Hybrid FC King

well damn that's just a t04 wearing a ht-18 jacket

that's cheating

What are you going to do for your wastegate?

 

The stock wastegate is ported but I have a 42mm wastegate. I will grind and weld a tube and flange on the stock turbo manifold to keep boost creep to zero

 

My car is not ported. I haven't found anyone with an S5 turbo with the upgraded wheel that can hold than 12psi to redline. If anyone has one on their car I'd like to hear about it. I think an S4 could do it just because of the tiny wastegate it creeps like hell. My S4 would hold 15-6 lbs all day long!

 

damn you guys are smart

 

Ya I couldn't get my hybrid to hold boost to redline which is the main downfall of any hybrid. I have my turbine housing machined and a larger wheel put in too. But I did have the stock catback so now with my streetport and full 3" exhaust we'll see.
