Holset Turbos

[DJpowerHaus]

Are there any benefits to using the bullseye housing other than having it bolt up? Different A/R... etc. etc.

 

[1029TSG]

There's a few reasons. I dont think the Holset turbine housing will even fit without hitting the block. The A/R ratio is sized for a 5.9 liter diesel application and you would have to change your manifold and downpipe.

 

[DJpowerHaus]

Well... mine is a top mount RWD tubular manifold with the propper flange. It wont hit anything. So what's the deal with that A/R? I'm sure someone must have some experience with a stock Holset bolted to a tubular manifold.

The original housing is designed for the exhaust gas flow of a diesel engine 3X the size of your engine.

This means a 2.0 gas engine would barely spool the thing...

Even a toyota 4 cyl diesel has like a 4" exhaust stock.. Diesels have alot of exhaust gasses..

 

[defrag010]

yeah, the stock holset turbine housings range anywhere from 12-21cm. Not to mention you would have to make your own custom downpipe.

I've always wondered if it was possible, though, to bolt up a HY35 to a T4 manifold because it's only got a 9cm turbine housing. Maybe on a 2.4 or something.

I found this site pretty interesting.. It shows the turbos that come on the different cummins motors.. It classifies the H1E as the same as an HX40, so I wouldn't give up completely on the H1E not working in the HX40 turbine housings... remember, there are lots of different assembly numbers..

I have chimed in a time or two. I have had an HX-35 for a little over a year now and LOVE it!!. I ran a 7.68 in the 1/8th on pump gas. I get over 20 psi of boost under 4k. I have not got it to the dyno yet. What else do you need to know. Ask away...

1. Can you post a pic?
2. Find out what it'll cost to dyno it locally. (I'll explain later, why)
3. What's keeping you from getting it dynoed?
4. Are you the one on DSMtalk, the supposedly had one installed a year ago?
5. I've read on another board, that someone had issues with surge? How about you? Anything abnormal about the setup that you've heard or experienced?

I agree, it'd be real nice to see some dyno graphs of those that are running them. Afterall, there is a supposed, 6 or 7 people running them. For those that have been posted on Bullseye's site for HP, they should have submitted a graph, right? Can't it be posted?

 

[defrag010]

just a little fyi, I was looking around on dsmtimes.org, and I saw that in the "other" section, a 95 mirage ran an 11.2 with a HY35

 

[BluemeanieTSi]

we're finishing up an hx35 on a 2g should be done today i'll have pics to post

 

[1029TSG]

Just received this in my email box

 

[pianoman]

Was this the guy with the HX-40 at 20psi?

 

[1029TSG]

I know what you're going to ask so I'll tell you everything I know.

HX-35 Internal at 25-26 psi
mostly C16
750's
standalone EMS
FMIC
Cams
Rods and pistons
Intake mani and TB
and the obvious bolt on's

He was only able to make 3 pulls and thought it was still too rich on the spool up. Some puffs of black smoke out the back. This was a discounted test unit and wont qualify for The Turbo Challenge, otherwise it would be $175 in his pocket.

 

[1029TSG]

No, that was Mark Wohler. This is Jason Morrow.

 

[93AWDTalon1]

these holsets make make alot of power without lots boost that Map Width Enhancement groove must help alot. Is that on stock head?

 

[1029TSG]

Its a ported 2g head to match his aftermarket intake manifold.

 

[gsxtacy]

That is a nice graph. 494hp, 420 ft lb.

HY35?

Damn.

 

[1029TSG]

HX, there are no HY's out there yet.

1)Here is the pic of the turbo. This is when the turbo on my 1G. It is on my 2G now.

2)The local cost for dyno time is $125/hr and it is a mustang dyno I believe.

3)I am the car is down for the winter. I am having problems with the ignition system and have just not got around to fixing it. It is too cold outside.

4)I think that I might have posted on DSMtalk. It has been too long since I have even thought about posting on there.

5)I have not had any problem with surge and I have has this on two different cars. The 1G was with a stock head and the 2G has a CNC'ed head with 1mm oversized valves.

The biggest thing is that my HX35 has been modified to be able to have a T04B cover installed on it. It was done that way to keep from smashing the water pipe because it was not know how much it would have needed to be dented. If I had to do it again I would have use the MWE cover and smashed the water pipe.

Hope this helps.

IPT...

Sometimes IPBeer.... J/k


I just tweeked the water pipe mounting tab to clear my 56 trim... What we really need are some mandrel bent water pipes which are oval or something across the middle....


I'm looking at some of the holset parts. Compwheel and cover only really for some larger sizes to be combined with a garret turbine side.... How is spool up compaired to a similarly sized turbo in a garret or .

I have heard that some diesel turbos have heavy wheels from being built for HD applications.. Then again any MHI like a 20g etc would be in the same boat.

I am not sure as to how this compares to a garrett turbo as far as spool up. The closest garrett combo would a 60-1 with a stage 5 turbine wheel and even then I would guess that the HX35 turbine wheel is still bigger.

I think that 1029TSG would be able to better compare the sizes of the turbine wheels.

To make the holset compressor wheel and cover work on a garrett center section would not be a easy task. First of all the back size of the compressor cover on the holsets are WAY bigger then the Garrett seal plates. In fact i had to have the seal plate on the holset cut down considerably for the T04B cover to fit. Also if you use a garrett center section you lose the indistructable bearings that holset uses. The garrett ones are junk IMHO compared to the garrett ones. And I say that because I have stalled my 2G (VERY VERY BAD on the turbo) more than once and have no shaft play and I did that on a garrett that I had once and trashed it out. TRUST me I went through five turbos in one year!!

I do have some ideas on how to move the water pipe, but again it is too cold to work on it. Can't wait til spring.

Is this due to compressor surge? or something else?

I'm thinking more on the lines of puting a garret turbine wheel on a holset CHRA...

What size garret CHRA are you compairing? As big as I am going it may be closer...

If the garret TS turbine housing needs some TLC to get the holset CHRA to bolt up it will get it.

My thought was, given you are the only one (if I recall) that has posted here and has first hand knowledge of the Holset on the car. And given everyone is hungry for a dyno graph, I was going to propose we get 20 to 50 people to all paypal you a $1 or $2 towards getting some dyno pulls and graphs for us to see. It's worth $2 to me. You'd have to pay the balance.

 

[MNGSX]

This is why I am thinking engine dyno... $480 for 8 hours...

 

[MNGSX]

Anybody know how the holset shafts compaire to a T4? There are two turbine wheel/shaft diameters...

What is the shaft diameter on your H2

Is this due to compressor surge? or something else?

On my 2G I have blown off the intercooler pipe. Or like I said I am having some ignition problems that was shuting off some cylinders.

My 1G I ran lean and ended up burning up and exhaust valve on the #1 cylinder and did not realize it for a week or two until I did a compression check.
