HX40 Variable Geometry Turbine

Hey Ted,
I would be very interested in Aerocharger as well. Thanks for your help.
Regards,
Michael

I agree with MichaelT. Seems that Holeset is not a viable option at this time, so let's go looking elsewhere. Besides, that would allow me to use my HX40s as cool bookends. #ad

Is it this one?

So far i have had no luck. If a company makes a turbo that will work, it,s not available after market yet. Also the cost is outragous. The other problem is durablity for us high hp trucks. But i,m still looking.

Ted Janetty,
Isn't the main advantage of the Aerocharger the fact that it has its own oil sump & does not require plumbing into the engine oiling system?

I've seen the Aerocharger turbos used on street bike conversions for the above reason. I'm not sure that a separate oil sump is a benefit on a daily driven truck.

I've known about this company for at least 5 years in the HD industry, when it first came out they had mentioned that they had done testing on diesel trucks. The part I like is there are no electronics on it, so its mechanical. Hey Ted, maybe now we can run like 3 of these things to make the turbos from the hd's work #ad
, they use 2 cylinders so we can, I guess at that point the boost limit would be the question. #ad

I have installed a few of them on bikes. There real nice but they don,t last. They usually wear out the seals and start smoking real bad. What would fix the problem is a separate oil reserve to help cool the unit down. The bigger units might be different.

I wanted to know more about that turbo.
This morning I've talked with a buddy, he's chief mechanic in on of the largest Iveco sellers here in Italy.

First off all I think it'll be a pita to stuff one off those turbos into a RAM.
WOW, is that thing BIG! It's also water cooled.

I've copied the turbo drawings from the Iveco
service manual. ( In Italian)
If anyone is intrested, I can scan them and send them to you. Let me know.

My buddy took me to a test drive on a truck with a 7. 8L engine with the VGT turbo.
I'm totally speechless! That thing runs 1. 0
Atm at idle. Ther's no turbo lag at all!!
WOW! #ad
#ad


So far...
The **** thing is available... NOW!
I can order it from Iveco.
The prices at the actual exchange rate are:
The complete turbo: 2. 600 US.
The actuator position sensor and it's proportional valve 550 US.
Plus taxes and of course shipping.

Needless to say, for a RAM application the sensor/valve combo isn't needed.
They are used by the Iveco ECM to regulate the turbine. Since the Cummins ECM has no such I/O you have to find another way to regulate the turbo.

Hope this helps.
Marco.

Marco, what is 1. 0 atm, is that like 1 bar? Since I can't read Italian it would do no good for you to send the plans to me but, what size shaft does it have? hx40=8mm and can take 50psi boost, hx50(H2)=9mm can take 60psi. I'd like to know how much boost can be made with the turbo your speaking of. #ad

Adam,


It,s a HX40 with a fancy turbine housing. It will work great for those 500 and under crowd. You need a H2E for what your doing.

I'd love to have something that'll handle 60+psi boost at 21cm2 and have the bottom end of a 10cm2. While I'm in the dream world, I'd like the option of 4 or 5" exhaust. #ad

I know the technology is there, we just have to find the people to build it. Seriously this turbo would be on everybody's truck over 300hp given the price was right. #ad

I still have two people looking into this,but it is not looking good.

Adam,
Have you thought of twin sequential? I'm considering it if the VGT is not going to be available, but at the same time I don't want to hack up the truck to fit two turbos. Anyone seen it done without having to relocate the stuff on the firewall? I was thinking the H2E off the manifold connected to the HX40-16cm2 wastegated. Granted, the VGT would be the cleanest install. Thanks.

There is plenty of room for twin turbos without cutting into the truck. I'm ordering a second hx40 16cm to try out a twin turbo setup. Instead of a sequencial setup I was thinking of making a Y casting off the manifold with a proportioning valve to the second turbo set at about 30 psi. Should be a good combo for reaching 100 psi without to much lag #ad
The oil return line from the turbos and the downpipe will be the hardest part. I have the choice of making the Y adapter out of mild steel,T1, or stainless. Which one will handle the temps?

Adam,
Why don't you think about a HX55VGT turbo.
That should be able to do what you want. #ad

Would it fit into a Ram?

Sorry, Ive forgotten. .
I atm = 1 bar

I have a guy that builds turbo's for my pull tractors if you guys want to go twins he has a setup for that also Hvac and myself will be talking to him about a hybrid charger for the 5. 9 the cool part is he just bought a ho 2500

00,
Not quite sure how you're going to get 100psi out of two turbos in parallel. The compressor output is a multiple of compressor input - Pressure ratio. It sounds like your proposed set up will feed the second turbo with ambient pressure. How will that get you to 100psi boost?

I was thinking of something similar to the garrett multi stage turbo setup. The compressors are still run in series but the exhaust I would like to run in parallel with a valve set at about 30 psi. Just seems that this would reduce backpressure compared to having the exhaust in series(or so says the voices in my head) #ad
If it doesn't work I'll just put it in series. http://www.egarrett.com/images/low-high-turbo.gif
