Holset Turbos, PART 3

[IPT]

I just heard and I will have to get more information.

But someone just made 602whp with an HX40 Pro in the Bolt-on Turbine housing.

As soon as I can get more information I will pass it on.

A friend of mine is purchasing the following for his 98 GST:

HX40 58mm compressor, 60mm Exhaust
BEP .70 A/R T3 Turbine Housing
Treadstone Cast T3 Manifold
Tial 38mm WG

This is all going on a 2.3 with 272 cams. Can anyone chime in with spool times and characteristics of these turbos in the T3 housing?

That will be a killer setup. There are not alot of the .70 a/r housings floating around yet. I would say he should see full spool around 3900-4200 rpms and be able to push that turbo to the limits. It will be interesting to see what he will make for power compared to the .55 a/r housings.

We are looking to maybe hit 500 on the 58mm 8-blade compressor if its possible on pump/meth or race gas. Then once we max out the compressor we are looking into the 60mm 6-blade "PRO" wheel to upgrade to when the "built" 1g head and smim goes on

The guys name is Badman21 but hes newb status so he can't post.

here is the pics hx40 (left) vs GT3076R (right) /dyno graph (he let off at 5k b/c fuel issues)

Does the stck Holset divided 14cm turbine hsing flow more than the .70 a/r housings?

 

[dsmconvict]

My old hx40 came with the 18cm^2 t4 housing...anything would be a better flowing upgrade. How does the twin-scroll housing help with spool and flow on these turbos?

Cool Now I don't have to post up that info. He sent it to me also.

I just noticed on the pic of the hx40 in the t3 housing. The housing to turbine wheel gap is large that seems wrong?

How so?WTF Perhaps it's just the pic giving you that impression I'd suppose.

 

[IPT]

He should try one of the .70 a/r housings and see how much of a difference it will make. He already has a T3 inlet and V-band O2 housings it seems.

 

[dsmconvict]

Thats what I hope to opt with. I'm trying to find a new project car to throw my 2.0 eagle/ross motor into. What are the differences in the Holset twin-scroll and the bep T3. Anyone have spool times and other info on the Holset turbine housings?

 

[JWoodley]

Can someone tell me the differences in:
WH1C
WH1E

Is one the equivalent to an HX35 and the other an HX40? I'm going to wind up piecing a setup together. So I need to know if the housings/wheels are comparable.

Thanks!

 

[dsmconvict]

If I'm not mistaken the WH1C= HX35 and WH1E= HX40. Someone please correct me if I'm wrong. But I'm pretty confident with the answers.

Thats what I thought as well. So if shaft is broken, will that require a new CHRA or can a shaft be sourced from Holset or other vendors?

Thanks again!

 

[dsmconvict]

Try dtmparts.com I've seen wheels housings etc on there.

The turbos can be rebuilt, you don't need to buy a new CHRA unless yours is fubar'd.

 

[JWoodley]

Can you fit a 6 blade HX40 wheel in a 7 or 8 blade housing?

EDIT: Sorry for all the questions.

You will have to have the compressor cover recut to the bigger compressor wheel.

Not really. The wh1c is like the pre-1998 hx35 except for the v-band clamped compressor cover. After that the hx35 comes with a better flowing 7 blade with a larger inducer. The wh1c does come with the MWE ring unlike the h1c (of which there are 2 compressors also). The turbines are the same.

The wh1e only comes with the hx40 8 blade. You'll have to machine to compressor to accept the better 6 blade or super 40 7 blade. The turbines are the same.

Thanks Matt for the info now I know for the future instead of sounding like an idiot.

 

[ceedawg]

Still ,which housings flow better, an external waste gated Holset TH 14cm^2 divided ,16cm^2 divided, vs or the T3 70 A/R divided hsing by BEP on a 6 bladed HX40?

 

[dsm-onster]

You're not really wrong either. Because, the wh1c will fit into a bep hx35 housing. And, a wh1e will fit into a bep hx40 housing. The turbines are the same. And for many, the differences between the compressors are negledgable.

But for those who want the most from their hx35 after spending the money and time will get the newer compressor design. And those wanting to push the hx40/h1e turbine will certainly look for more compressor than what the wh1e provides.

No one knows. . . You'll have to test it out. Holset housing almost forces one to run a better o2 housing design. . . That DOES count for something . . .at the hx35 flow level. Who knows? Only a log will tell.
