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

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?

Perhaps it's just the pic giving you that impression I'd suppose.

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.

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 · 02-07-2008, 10:16 AM

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 · 02-07-2008, 10:40 AM

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!

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.

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 · 02-07-2008, 04:58 PM

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?

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.

Yeah I have an 8-blade HX40 and was looking at the maps and where you said the 8-blade might be the lowest flowing compressor. The measurements I was given at the time of the purchase were 58mm on the compressor and 60mm on the exhaust. I want to opt for the htturbo 60mm/6-blade compressor upgrade. Is this the same compressor used on the PRO/SUPER 40?
