Holset Turbos, PART 5

[1gDSM4g63]

Minor dent, but it also depends on the manifold you have.

Whats the latest news on HX52? I found a post on a diesel forum... idk how accurate it is.

This map shows the pro-52 flowing damn near 120
The compressor wheel is 71mm and comes with a 16/cm2 exhaust housing with 70mm turbine wheel. basicly a hx55/hx40 hybrid but has newly designed wheels (2004?)and a special high flowing turbine trim.
Diesel guys push this turbo to over 50 psi on a regular basis about 600hp.. but thats diesel HP. On a gas motor this is a 1000+hp turbo.
There is also another hx52 turbo non "PRO" that came on volvo diesel trucks. it has a 67mm compressor wheel and a smaller shaft than the PRO52 so it cant be pushed as hard.

I imagine he is is telling the truth, but I was wondering if anyone had any more measurements or results, and most importantly information on how to aquire this hx52 pro stuff.

Most mitsu mani's generally put the turbo in the same spot.

I had to dent my waterpipe a little for the 50 trim

Just wondering how much more if any for the HX

Even through it's a BEP .55 a/r Mitsubishi housing the HX40 is a monster size, so you'd probably have to dent it a little more.

 

[kawboy]

Would a spacer plate affect spool? Powerband? etc?

I wouldn't like to crush it near half it's size.

 

[andy4g63]

It isn't half the size. Just wrap it up with something and put it in a vise and go little by little. You don't need any spacer, not to mention, that you may run into front motor mount...

Andy/Kawboy,

I did use a 1" spacer with the FP race manifold. I did not want to crush/dent my water pipe at all. When I begin putting the car back together in the next week or so I plan on ditching the spacer. It's more of a pita than anything else.

If necessary I will get some 90* silicone couplers and make the water pipe do this little number below the compressor housing:

---|___|---

Cut the pipe in the area that needs to be dented and reroute accordingly. Looks good in theory...atleast somewhat.

That diesel guy is confused about the 120 number. That is a mass flow perameter used by holset as seen on the bottem of the common green holset maps. The conversion of that number to lb/min is through multiplying it by 0.77. The hx52 doesn't flow 120lb/min. It has a mass flow perameter of about 115 and thus flows 88lb/min at the edge of the map:

Just won this one on ebay. HE551V. For diesels up to 16l and Holset rates the HE500 series for 295-650hp. Those are diesel numbers of course. Probably closer to 900ishon a gasoline engine. I'm expecting samewhere around a 67mm compressor wheel.

It will be going on one of our combines at home as another VGT experiment as it seems to have the same near t4 exhaust flange like the HE431v we have on one of them already. I'll be measuring all the wheels and VGT nozzle area to include it in the VGT info on here when it comes as well as some more pictures.

Info will probably be going up at the link below first but I will get it here eventually. Might be interesting for the Hx52 guys.

Hey guys can anyone tell me what size the vband flange is for outlet on the compressor side is?

Hey guys can anyone tell me what size the vband flange is for outlet on the compressor side is?

Usually 2.5"

 

[95GSXCO]

Thanks guys I order my BEP last night from the turbo trader so hopefully it wont take that long to get it Now just have to find me a 2.5 vband clamp and flange the more couplers I can get rid of the better.

 

[twistedcm2]

I just had a quick question about the oil return bolts that go into the holset turbo. Mine did not come with any and I just wanted to know if any one had the bolt size.

So in other words just the two bolts that would hook up the oil return fitting line.

Thanks for the help.

Is anybody using v-band connections for the compressor cover, or any of their charge pipes? Im going to do my own piping, and was curious what people were doing.

I'm using all wiggins clamps on mine which are pretty much the best clamp you can get and still have give so you don't break pipe. They're like $45 each but you get leak proof connections.

 

[95GSXCO]

Iam going to be using a v-band on the discharge pipe off the turbo and here shortly I will be running one off my TB and exhaust side on the turbo and the down pipe for engine swaps. So much easier to take when the time comes

Thats looks to be off a 15.0 liter cumeapart ISX.

I've never heard of a wiggins connector before. You mention it is leakproof. Is there any cause for concern with vband connections?

They don't provide enough give for IC piping. If you look at any cars like Shep AMS or any of the big name shop cars they all run wiggins clamps. They are not as easy to install as people think or atleast the ones I have aren't but they are def a better design than anything else out there.

Ah. I have seen those before, I guess I just never knew the proper name for them.

Im really thinking about using the v-band at the compressor housing, but im not sure if its really worth the extra work to v-band the intercooler and throttle body. And the added cost.

Thanks for the pic!

I'm gonna be using a v-band at compressor outlet and wiggins everywhere else. Proven leak proof performance worth the investment in my opinion as I see like 100 threads about boost leaks and losing power a week.

 

[kicker91laser]

Sean, have you considered simply going o-ring vbands throughout?

 

[Slippi84]

Yes I did I even posted about them and then found the wiggins clamps. Thing is I already have the wiggins clamps. I might even have extra because my IC setup I'm buying comes with them.

 

[VETTE_50_TH]

Just got my HX40W and t3 housing in today. That thing weighs a ton with the stock Holset turbine housing on. , i was like WTF. Im getting the housing ceramic coated, then slapping it on.
