Holset Turbos, PART 4

[chrisb33]

I have that exact one look at around page 10 or something .

ey youre right! it's on page 10. Are you running the holset already? i checked your profile and its says there youre still using a 16g.

On the hx35, are you planning to use it internally gated?

thanks.

Would it be better to run the stock divided housing on a non divided manifold or go the bolt on housing route?

Also I found an hx40G? Whats the g stand for? Also its an 8 blade. Whats the flow rate of the 8 blade and does it spool faster than 7 or 6?

I STRONGLY recommend running a true divided-runner manifold with the stock 18cm^2 housing and an hx40 turbine wheel. Having the runners divided will make all the difference in the world for spooling the hx40. How fast does the wh1c spool with the non-divided header and stock turbine housing?

Can you estimate how much sooner the spool will occur on a stock Holset 18 cm over a BEP T3 .70 housing with a true divided-runner manifold? I mean when you say STRONGLY I get the feel it is more than what AXRabbit376 said...

I've heard between 200-500 RPM quicker spool...

I just want to know if it's worth switching housing again with twin-scroll manifold.

That guy is feeding you horsesh!t. I can't believe the rediculous 'turbo builders'. They tell you that this turbo is rated for 600whp. . . When that is only the compressor. They know good and well that it is nearly impossible for a 4cylinder to get that kind of power out of a t31 wheel even with a .84 a/r turbine housing and tubular header. Yea their rating of the turbo would only go up 30hp, but you can't get the maximum power out of 60-1 wheel anyway. Upgrading to the t350 wheel would have netted you 50 or so horsepower easily and given you the ability to actually get to their rated hp level of the 6031. The 6031 spools faster than the 6052 FOR A REASON. And they should tell you that. . .

The hx40 spools 500-600 rpms later with the same BEP housing vs. a wh1c/hx35. An 18cm^2 housing is MUCH bigger than a 12cm^2 housing. I STRONGLY recommend running a true divided-runner manifold with the stock 18cm^2 housing and an hx40 turbine wheel. Having the runners divided will make all the difference in the world for spooling the hx40. How fast does the wh1c spool with the non-divided header and stock turbine housing?

I know now that the t31 wheel is a waste. At the time i didnt know enough and just figured he would. I was wrong i guess. I had to replace the compressor wheel on it anyways so i wanted to upgrade it to their 6152, but "on paper" it was only showing a 30hp gain. The 6152 is i believe the gt30 compressor wheel with the t350 turbine. I probably would have been happy with that setup.

I cant give you an accurate spool rpm for the wh1c. It has zero exhaust hooked up to it right now, so that would change where it will spool when its all hooked up. I didnt even hook up my logger for the test drive. I only drove it a couple of miles to work out some bugs and try to get the boost stable. I ran out of time, so i had to stop messing with it. If i had to guess, id say maybe mid to high 3k range. Again, thats a guess. This is on a 136k mile 1g with hks 272 cams. Everything else on the engine is stock. I was expecting it to spool later since im using the holset housing and not using a divided header. I found a v-band flange at a freightliner dealer, so i might make a downpipe for this turbo. I havent decided yet. Is 3" exhaust too small for a hx40? If so, ill make the downpipe for the wh1c and use it on another car.

I have a 16cm hx40 exhaust housing too, but it has some aluminum imbedded into it. I dont know if i would be able to get all of it out or not. At this point im probably just gunna cross my fingers and hope the 18cm housing isnt too laggy. I need to get a header flange to use as a spacer for block clearance with the hx40.

Here are a couple pictures i took of what ive got so far.

Dent the water pipe if possible. Using the spacer requires longer headstuds. I fashioned my own from a 3 foot section of all thread from Fastenal. I would not recommend this due the weight of the turbo. It's a chunk.

When I bolt everything up to my new longblock in the next few weeks I'll be going back with m10 studs.

FIrst off you have two wastegates on there right now or atleast it setup for two. Take the internal gate arm off and get the flapper welded shut second I had the same hotside on my hx40 just with a bigger outlet so I feel your pain. Only real solution is either get a custome dp maid that is pinched on one side or a spacer to lower it to avoid the water pipe or whatever else your hitting all together. Kinda a crap shoot either way. I would just get a different manifold that looks like a XSpower ebay one anyway shouldn't put you back to much anyway,

This is going to come down to opinion, budget, and what you already have.

In my opinion, it is much better to put together pieces that were designed for each other. The twinscroll housing is designed for the non-divided header design. The bolton housing simplifies things and has not been proven to be a restriction to the hx35 & hx40 turbine wheels. And is more affordable to install, since you don't need to buy a t3 manifold and customize an o2 housing.

The 8blade hx40 has a compressor map very similar to the t04b 60-1 but with much better high boost efficiency. The hx40g comes from a dh10 Volvo motor commonly found in transit busses. My h1e is from a cummins transit bus motor and it has an 8blade compressor with the same dimensions as the hx40 8blade compressor and has the same turbine wheel as the hx40.

I plan on running it external with the bep t3.70ar hotside. I'm trying to save money so I can get the t3 punishment mani and external wastegate.

 

[Morphius]

Who's going to pony up to this? Anyone?? HX83 vs 03 HY35. Man, I wish I could bolt in on my 5.9.

 

[dsm-onster]

You just mount it on the roof of the car and use antilag, it will make up for the slow spool with jet propulsion . . . Better yet, just remove the engine; it's unwanted weight. Feed the compressor right into the turbine along with fuel. Now you're down to only one moving part and one sparkplug!!!

. . . You could get out of cars all together and build a small turboprop and beat the traffic every day. Or take you're track car to the race in style.

 

[JWoodley]

Morphius, whats the retail price on that unit? CFM rating?

 

[dsm-onster]

The hx83 is rated at 1.1 kg/sec based on the cummins published map:

. . . This is 146 lb/min.

^^^So what would be the garret counterpart to that

It is a XSpower ebay header, but it was free. I take anything that is free. This was really only an experiment. The pics are of my wh1c, not my hx40. My clearance issues are caused by this header. The turbo flange is on an angle to give you extra clearance for a compressor cover, but at the expense of room for the exhaust housing. Im happy with the results so im going to stick with holsets. I have the wg on the header blocked off as part of my experiment too. People always say you cant use the holset wg setup because your boost will be too high, but I couldnt find data from anybody that tried it on the wh1c. Im not complaining about too high of boost. I was trying to push my PTE to 35+psi, but it wasnt happening. Ill do a little more testing with it to see the lowest that i can maintain for referance. I havent taken off the outlet cover on the wh1c, but the bad hx40 i took apart looked like the wastegate hole could be ported out if need be. I would assume the wh1c to look the same way.

Like i said, Ive got $20 invested in stuff i had to buy for this so far.
Header: free
Oil lines: $20 had to buy 2 adaptor fittings to make my PTE lines work
Turbo: already had

If i like the way the hx40 performs i will look into a different header for that, but with the wh1c so far im happy with it the way it is.

Matt, do you really think, that this 8blade on the HX-83 will restrict flow? Because before you mentioned, that HX-40 8blade is less efficient, than 6 and 7 blades/ kind of flows less and it is with more blades, kind of restricts flow/. But seeing here 8 blade on that BIG of a turbo makes me wonder. Also I've seen 8 blade on some BW turbo and that was big too.

 

[dsm-onster]

It may have 8 blades but it has a HUGE fncking inducer. Inducer trumps number of blades.

 

[Slippi84]

That's just out of control That things has to be the biggest turbo ever. What's scary is I know there's bigger too. Anyway Even with a 2.4 stroker that thing would have a useless powerband. If I had a 5.0 mustang or something I would run it. Might work on my 3.7 jeep give me the top end of a vette . That is one bad ass looking exhaust flange too

 

[darkhorizon]

That HX83 should technically support upwards of 1600whp! HOLY SHNIKIES.

I would love to see a 2jz spool that turbo.

 

[jking29]

Holy cow! That hy35 next to the hx83 looks like my 14b next to my hx35!

[chrisb33]

guys, if anyone has a BEP mitsu housing (external gate) for a hx35 for sale kindly PM me. Thanks!

I tried Timturbo but i think he's out of stock coz he's not been responding to my emails as of late.

I really don't think those wheels are true billet. You all realize the complexity to CNC a compressor wheel? At $100/hr, I can tell you it'd take ALOT more than an hour to make one.

I'd bet it's merely the machining marks/etc, from the mold to produce them. Might be one particular part# wheel that the mold wasn't finished as nice as typical and you can see the marks in the mold.
