Holset Turbos, PART 8

[JusMX141]

You can port it if you'd like....although that little bit of flashing hanging over is not going to make or break your setup.

Thought I'd add this to anyone interested. I picked up the stock v-band clamp and elbow from a stock cummins truck with an hx-35. I think it will work well. The oulet on the elbow is 2.5" so it should match up perfect with my intercooler piping. I picked it up on the cummins forums from a guy parting the truck out so I got it dirt cheap. I think its a good alternative to grinding the lip off and putting a coupler there.

The factory elbow is ridiculously long; it will likely stick out below the subframe(it would on my 1g with my turbo placement anyway). If you can find a *tight* 90* 2.5" elbow and weld the factory vband onto it it should work out almost perfect. May be able to cut out a section and re-weld it, too.

 

[richard33]

ya that looks like its going to hit the motor mount/subframe. I think it would be easier to just grind down the v band and put a 90* coupler on there. Thats what I have on my 2g running 38lbs and never blew it off once.

 

[Gstclipse69]

Thanks for the advice. I'll have to mock it up and see what needs to be done. At least I got the v-band instead of having to shell out for a new one of those.

My thinking was there was going to be a lot of downforce coming right out of the compressor housing. Thats why I was leaning towards the v-band. I'll see what kind of modification I can do.

my friend has 2 hx40 which i could get for free what factory housings do they come in? looking to make a true twin scroll setup so which manifold would i need? ts t3 divided manifold?

 

[viperlp01]

Most likely a T4 twin scroll 17cm^2 housing

And maybe something like this?

okay thanx would something like this work http://www.dsmtuners.com/forums/bolt-tech/390102-jhracing-twin-scroll-manifolds-may-back.html

Hey was recommended by Justin to post the picture of my oil feed on my H1C. It looks to be a recessed 5/8th inverted Flare fitting. Anyone else see something like this before? I have the drain setup now I'm just working on the feed portion of it, trying to figure out what adapters I need.

 

[kicker91laser]

You may want to take the turbo to a local shop that builds automotive/industrial lines, they should have something that works for you or can tell you what you need.

 

[JusMX141]

Is that recessed into the feed hole? Something doesn't appear right about that oil feed fitting....it's like nothing I've seen on any Holset before.

Yeah it's recessed. That's why I was stumped trying to search the forums looking for what I needed.

 

[dragonov_elite]

Seems like most holset h1c's have that recessed oil feed.

Here is a video I took of my h1c.

Don't laugh its a bad video .

Was out doing some tunning running a little lean between 5500-6000 rpm little maf calibration is all it needs.. Any how on to the videos Running a HX40 T3 on single scroll manifold. Im saving up for a twin scroll now. Boost is at 32-33 psi running E85 Ecmlink 21* peak timing advance.. hard to hold iphone shift and control the car as sametime. Was trying to get some video of the spool up and boost response for you guys.

Nice! It does seem like all hell breaks loose after 6000 rpm.

It does I was babying it granny shifting.. but yes pulls very nice wish I still had my JMF intake manifold.. I will be picking up a Magnus soon.
here is a pic set up.. Should be uping the boost soon 35-38 psi.. Bye the way Thanks jusmx141 for the turbo rebuild!!!

Mine looks like all I've seen. NOT like that. This is my h1c. And my Wh1e is exactly the same.

 

[Silvertune]

Yes but that's a Big H1C. The smaller ones have more different bearing housings.

 

[talonDSMerr]

Am I measuring the compressor inducer correctly? This is an hx35g, I was expecting the inducer of the 7-blade compressor to be ~54mm. The exducer is 78mm.

 

[JusMX141]

It's very difficult to measure across the inducer of a wheel with an odd-number of blades.

You have a 54mm / 78mm 7-blade.

 

[talonDSMerr]

I understand that, but I find it hard to believe I'm off 5mm because there are an odd number of blades. If it measured 52-53mm, sure. Even measuring the ID bore of the compressor housing gave me ~49mm.

Eww. You might have another oddball unit. An HX35g is probably one of those natural gas units, they generally won't have as big of a compressor as a diesel unit. If it really is only 49mm your in the realm of a 20g.

At least you can upgrade the compressor to a 60mm one for like $200.

And around another $100 to have the housing machined for the 60mm wheel as well.

I think it's safe to say not all hx35's are created equal. The hx35w's that are found on the 5.9L cummins might all have either 56mm (94-98.5) or 54mm (98.5-02) compressor inducers, but hx35's used on other applications likely have a wide variety of sizes and specs.. This being one of them.

 

[LiquidX]

Just to clarify for you. When measuring the diameter of a wheel with an odd number of blades you need to measure the radius and multiply it by 2, that will give you the diameter.

It doesn't matter if the hole in the compressor housing is only 49mm.

Get a good measurement across the three points. Multiply that by 1.05, and that is the diameter of your wheel. So according to your current measurement, your wheel is 51.85mm. Right in line with a 20g, or a old school 50trim, good enough for 450whp on E85, and 11 sec slips. Get a BEP housing for it and have fun.
