h1c exhaust q

[Husker6.5]

Can you measure tush torque with that butt-dyno?:biggrinjester:

 

[STEVE53]

I have the complete wh1c turbo, so no need to machine the h1c housing for the larger compressor wheel. Plus the wh1c compressor housing has the slots cut into the intake, not sure what they are called right now (MWE?). What purpose do these serve and are they necessary for a low boost application like I will be running? I say low boost because I will not be boosting the full potential of this turbo on my motor.

MWE,(map width enhancement) goes both ways on the spectrum, although is more prominent on the top end where there is more drive from the exhaust heat/gases... all it does in simple terms is prolong the effieciency of the turbo in its sweet spot on the map.... and i think it also minimizes turbo bark( although i am not 100% sure on that, maybe one of the cummins owners could clairify that)

we are talking 1.5-2mm of difference, not even enough to have to machine the housings to swap stuff around.... we have tried all the configurations of all the versions of H1C used on the dodges, and the WH1C, and a hx-35 off of a Feller/Buncher( industrial 6bt) everything mixed and matched( 17 different versions since march) and i can say from our testing that the most difference on the butt-dyno was changing exhaust housings.... the minimal difference in wheel sizes was not noticable in egts, boost, or butt-dyno....:thumbsup:

What pressures y'all run? And an hx-35 from an offroad equipment is slightly different than the dodge version.

 

[littleboy]

I'm not exactly sure why anyone would run such a small turbo on this size of engine. We use hx-35s on 3.8 liter engines. I wouldn't go much smaller than hx-40 .

we run 25-30 psi boost on this motor ( 457 hrs. worth) normal driving we see anywheres from 3-15 psi, with hard throttle runs up to 30psi..... the only difference with the hx 35 was a 12 cm2 non gated housing, and a slip on connection versus the v-band, the measurements were identical on both wheels, 56mm 83mm/69.5mm 60mm... took the measures for the stock 1996 35 from a friend with a dodge on another site.... his was running the 12cm2 gated housing.... the configuration we are running now is a 56/69/16 wh1c/hx-35/h1c mix... gotta love the v-band CHRA attachment, gives the ease of changing stuff right on the truck.... the snap ring is alright, but can cause finger carnage if it slips under tension, ask me how i know...:rolleyes5:

Size isn't the who story....

Size isn't the who story....

fortunately no one on this site or the other site needs to look to you or your brother for full answers or the whole story, because your posts like this one are tiring and disappointing... why dont you share instead of doing this..... i went through all your posts and cumminsfevers as well on every other site that you have joined and i never learned anything from either of you....:nonod:

It is true, you can lead a horse to water but you can't force him to drink .....

Because some can stumble across these turbos for dirt, they can work and they are better than a GM-4. I had about $300 into my WH1C swap, including cost of the turbo and rebuild kit. Most of the cost was buying the install kit from racedaymechanic because i don't have a welder, so i needed someone to do the hard work for me.

If i could have afforded too i would have gone bigger, but this is where my pay grade currently is.

 

[littleboy]

This is true, although if you know what to get you can walk through a scrap yard an pick up bigger turbos just as cheap . Most scrap yards have no clue.

Your scrap yards stock this kind of stuff? We have 2 local yards, 1 sucks and is always picked over. The other yard has a few 6.5 trucks, once in a blue moon old cummins gen-1, and a old 7.3 skewed in there.

 

[littleboy]

Well, we have a couple yards around here but you know how it is, when you need something they don't have it. Next time you are there they have 5 of em. I usually try to go with a fairly big list of parts i can always use.

Can you give a list of different common vehicles to be watching for? I'm new enough to diesels/turbos that I don't know what other diesels may have in them.

I went the HX35W route basically for the same reason that Dieselslug did. My HX35 came off an 01 Dodge. I would love to go up in size a bit if I could find something inexpensive enough.

Recently Craigslist in my area had an HX40 off a Dodge, but the seller wanted $400 for it.

Look for medium duty diesel trucks.

I know the 8.3 cummins and cat 3126 have nice turbos on them in our size range.

400 for the hx40, is it ready to go?

 

[littleboy]

The 8.3 has many variations of the hx-40 an it predecessor the H1e. The hx-40w or WH1e are the best of the options. All of them will have t-4 mounts though. An 400$ for a genuine holset is about right.

 

[Cumminsfever]

Volvo also used the hx40.

I went to Craigslist to see if it was still listed, but couldn't find it, so apparently gone. The big point for me is I just don't have that much cash available right now.

That is where I am also. I am looking for a low-buck approach to increasing the performance and reliability of my truck. I was not actively looking for a new turbo but the h1c and wh1c that I have now just popped up on CL for cheap so I bought them. Also, they bolt on with minor fabwork (downpipe adapter, comp. housing to air intake and comp. housing discharge to engine snorkel).

Any idea what drive pressure is at 30 psi of boost?
