Holset Turbos, PART 6

[turbotalon1g]

^Thanks for info. I plan on running the same setup here in a couple of weeks.
What are you using for an oil feed? restrictor?

When do you see 20psi?

 

[need2boostpsi]

im running from the head no restrictor, i see 20psi by 3500+/- and 10 psi by 3000rpms, thats on my hx35.

 

[turbotalon1g]

The turbo is ok like that?
Sorry turbo oil feed scares the shit out of me, I've had a scm61 shit because of dumb oil feed issues.
my motor is rebuilt, with no BS, has really high oil pressure. 100psi by 6-6500 rpms.
Usually has 10psi at idle but i have seen it go below on occasion.

Right now i have oil feed from the housing, but i would rather do from head, if i use the housing line then i want to do a restrictor for sure.

 

[need2boostpsi]

depends on your oil pressure, my car has high oil pressure so its perfectly alright for me, feeding from the OFH is scary to me. i think most ppl feed from the head with a holset and no BAlance shafts.

i have a 6-blade hx40w that i dont know much about

Ive only seen 2 t3 flanged hx40 housings, but im not sure if there is more. 16cm and 18cm. I have both, but my 16cm housing is messed up so i cant use it. There is a very noticable difference in the size of these 2 housings.

im running from the head no restrictor, i see 20psi by 3500+/- and 10 psi by 3000rpms, thats on my hx35.

I was also sourcing oil from the head with a -4 line and no restrictor. I still have my balance shafts, but my oil pressure is higher then most dsms ive owned going by the stock gauge. My scm6031 was also hooked up the same way for 5 years without issues.

In 3rd gear i would see 25+psi@3700rpm and it would start to go positive around 2500, but cant remember when it would hit 10psi. It would start to climb quickly from about 3400rpm-/+ though

This is what I do, no BS and no inline filter from the head.

Once I max out HX40 in .55BEP, I think I'm going to take my chances with the 18cm housing.

 

[Wicked95AWD]

On my car when i switched from a wh1c (8 blade hx35) with a 12cm housing to a 7 blade hx40 with a 18cm housing, my spool changed from 3700 to 5000. Hopefully that gives you a little bit of a reference.

Were you using a divided (TS) manifold with the 18cm housing?

 

[freeride_ca]

I'll be switching to a holset next month. I just picked up a 6 blade HX40. With the 16cm turbine housing. I don't know what way to go with it though. I want to keep my existing header (punishment racing made to clear a 35R) As well as my external waste gate. Should I weld the internal flapper shut and run this housing? Or switch to the BEP t3 .70 ar housing? This is going an a fully built 2.0L with 9:1 compression and HKS 272 cams. As well as all supporting mods. Which way would be best for me?

 

[turbotalon1g]

Guys that provided the info on oiling. thanks.
I already have the line from teh OFH and the fitting on the turbo. I might just do that nitrous restrictor thing though.

Thanks

No, i was using a cheap ebay non-divided manifold that was given to me for free on both holsets. I will be making an adaptor for my JHRacing manifold just to see what the difference is, but that probably wont be untill after i play around with the hx52 a little bit.

Once I max out HX40 in .55BEP, I think I'm going to take my chances with the 18cm housing.

Unless you are going to use a twin scroll manifold, id suggest the 16cm housing unless you already have an 18cm housing for it. If my 16cm housing wasnt messed up i would have used that on my setup instead of the 18cm.

Id at least try the 16cm housing first especially if you can weld it yourself. If you like it, then you just saved some money

I don't know if this has been asked or answered. But can I get the 6 blade hx40 wheel for my 8 blade hx40. Would the compressor cover need to be machined? Is this even possible?

 

[dsm-onster]

Yes, you ca buy the wheel and compressor cover here. Ask Justin (jusmx141) if the hx35 shaft is the same diameter as the hx40. I think they are. If so then that kit will work. You need to buy the cover too because the 6blade and 7blade hx40 compressor wheels hve a 60mm inducer and the 8blade has a 58mm inducer. You may be able to have the cover machined for it, but I don't know if the cost and time tracking down someone who can is worth it or not.

Yes, the compressor cover would need to be machined for it to fit. Most places (diesel shops) will charge $100-$150 to do it.

I just came across an hx40 but it has the 6-blade 56mm inducer. I've searched but I haven't found any info on this particular setup. Is this turbo worth the effort or should I try to find one of the more popular versions? I've maxxed out my td05 20g and I'm looking for an upgrade to get me in the 550hp range. Any info would be greatly appreciated.

6blades are 60mm inducer while 8blades are 58mm i believe. Any pics? It could be a bad measurement by the seller?
You could consider upgrading the turbine wheel on your 20g to td06h for a more power capability as well. The tdo5h turbine cant really match flow with 20g compressor above 24psi or so

I'm thinking you must be looking at the same seller as me, I just bought a 6-blade hx40w, the seller stated it had a 56mm compressor wheel. I wasn't aware that they had a different size 6-blade other than the 60mm wheel.

 

[Morphius]

Morphius, are you going to actually do the minutes for these threads!!! That would be a huge undertaking! It would be awesome to get a table of contents. Something like an outline. It would modifiable too. Just add or change headings and subheadings; and add or change posts relating to the headings and subheadings. This would be good to do with the other threads. I remember stuff back to the beginning, but finding it for a reference is !!!

I'm going to try it. I had Paul (99gst_racer) undelete the second post in the thread. I moved and added some brief highlights for posts for each page. I'm only through page 2 so far. I have to go back and bump the post count 1 to account for this additional post at the start. I might make it like the very first post (linked) so you just click each post link to view it, but it's even more time consuming, so no promises there.

We'll see how it works.

I need to contact Ludachris to see if a post can be added at the start of each of the Holset threads to do the same in the them.

This is true- the first HX40 I ever bought definitely has a 6-blade compressor wheel smaller than 60mm. I couldn't get an actual measurement because all (6) compressor inducers were mangled beyond recognition. It was apparently an oddball- I couldn't find parts for it anywhere going by the stamped number on the cover, and once I finally located a compressor wheel for it the price was double what I thought it should be. This particular turbo had "Volvo" on the compressor tag.

I ended up parting that turbo out, making more from selling the 16cm2 turbine housing alone than I paid for the turbo.

Any idea how long ago the turbo was manufactured?

 

[gbradley]

The comp inducer is definitely 56mm, I measured it myself. It has volvo on the tag also. I did google this turbo and came up with a little bit of info on the cummins forum. The turbo is in excellent shape, that's why I would like to use it. Other than the inducer it looks identical to any other hx40.

Did you measure the turbine wheel at all? Is it the usual hx40 turbine? Any idea of year manufactured?

 

[gbradley]

65mm turbine wheel. I'm not sure of the years of manufacture. I'll post some pics shortly.

 

[andy4g63]

Yes, there are 56mm inducer HX-40. One of the guys, that have it is Jason, AKA ihatedsms... Ask him, if you have more questions. Here is link, to his build thread.http://www.dsmtuners.com/forums/drag-strip/290305-my-1992-awd-drag-talon-build.html
