Twin Turbo 1HD-T!

[ForealBoreal]

Check out what I found running 50lbs of boost.
Would love to track down more info on this set up.

Looks like a simple compound setup, fairly common in the cummins world. Simple to make but turbo sizing can be tricky.

Ahh those engine displacements have been sorted out for almost 10 years now for comounds, A tried and true compound set up is hx30/hx35holsets. You can do better than that with tweaking and more modern turbos, but it will work well up to 50lb max. Compounding a 4L ish diesel motor is easy, so is a small 1.9L motor... compounding displacements inbetween is harder as the only other guys who do it are mercedes guys who rev up to 6 grand and have sheds full of motors they seem to blow up just for fun. Up till now no one here seemed to care about comounding the 4L motors, but if anyone is interesed id be more than happy to point you in the right direction. Now the real question is.... does anyone have the balls to compound their baby.... Id keep a spare crank in the shed just in case.

I love that pic of that guy running his low set turbo with no air filter right next to his cut out wheel well. Be neat to see his compressor after just one drive around the block. Ive done stupid things, but I dont believe id try that one out.

"The pod filter is too restrictive so it was taken off for the test drive."

Yep.

Shure would be fun while it lasted though!

I am dreaming of a 150kw + (200hp +) 1HZ gturbo'd HZJ75 boosting 25psi.
Something I would like to do

I'll bite.Well gerg I know I'm a little old ,but I always wanted twins,we should talk doc. You rattled the magic cummins combo off like it was nothing ,I know you were thinking the twin on your toy b ,is there a simple combo for the hdt ,I might be into trying it out if only for a bit .and you'd be able to test drive the before and after,me being local and all. And I thought it was the head not crank that you needed for a spare ,

Ok boys I'll backpeddel here a bit. Im a nurse who works on his truck as a hobby and gets yelled at by his wife when he does. I dont build manifolds as a buisnedd per say, but I would for sure help you find what would work and what wouldnt and source it as well for you. My point was that what you want has already been well researched and wold translate rather easily to your engine providing there is room and your good at grinding.... with a grinder that is.

A 25 psi compound set up and you would be better off getting a grunter turbo for the work involved. Building a compound manifold is time consuming and I havent really looked into your engine bays for room, although I bet it would fit alright. I guess off the top of my head I would recomend an he221 or a td04hl-19t-6cm MIH turbo or a td05-14b-6cm for smalls and an hy35 hoslet and a really nice large external wastegate... say a 60mm. The td04 would have to be made and would run around 400$ and all holsets can be had for under 350$. It would spool very hard in the low rpm and would provide 25lbs boost easily. You could also use a hx35 or an he351 as a large if you ran lots more fuel, as in bigger plungers. I am just throwing stuff out there and am by no means an authority on compounds, but better people than I have spent tons of time on this with 4bts and 4bd1s and had good results. Mostly they use holsets, but many other turbos would also work.

I guess we should talk again if you like wrongway, you should still have my number. If not pm me.

Interesting

 

[Wheelingnoob]

On my 4BD1T I will be starting off with a TD04-19T with 6cm turbine, if and when its no longer enough I will probably use it as the small turbo in my compounds. Would still limit my overall boost to 30-35psi though for reliability. I also have a 50mm external waste gate kicking around as well.

I think the tranny would be the hold back to more power in my setup.

 

[gerg]

That would be a very responsive little turbo, but do be careful as a true td04 has an extremely small turbine as opposed to a td04hl. The MHI turbo series uses the td as a prefix for a center section. The 04, 04L, 04h, 04hL are all progressively larger turbines. The TE04h is an oddball but is inbetween an H and an L... sort of.

Sorry my bad its a TD04HL-13T with a 6cm turbine. I'm planing on rebuilding it and putting on a 19T compressor and cover.

Ahh nice noob. Here is a good quick look at turbine wheels.
td04 1.57/1.86 trim 71
td04l 1.62/1.86 trim 76
td04h 1.74/2.04 trim 73
td04hl 1.80/2.05 trim 77
te04h 1.88/ 2.01 trim 87
td05h 1.93/ 2.19 trim 77

What is nice is that you can also change up your exhaust housing a bit if you want a tad larger. Here are some 7cm housings.

Now if you go for a td05hyou get alot more options. You could get a td05-14b-6cm for cheap as they are dumped off DMSs to upgrade, and put a 16g large wheel on it and it would spool pretty close to the td04hl, but would flow much better up top. You can also get aftermarket 7cm, 8cm and divided twin scroll housings for them as well.

Ohh and I forgot to mention that dougal is the one that sort of figured out the TD04hl 19t thing. All props to him, and you know hes a really good dad too. It is a funny story as it kind of happended in a round about way. Well its sort of here and there. Actually its a collection of things. In short the he221 is very close to a td04hl 19t. Its funny cus the td04hl 19t is know as a crank breaker in the gas world. Id like to see them run the he221!. Both have 6cm housings, but the he221 has an even bigger compressor.

Gerg i was not calling you out ,your a doctor as far as I'm concerned . As far as the single turbo you said ,, i don't think I would see enough gains to warrant the cost ,like you say if I'm handy in thefitting that parts should be had fairly cheap ,got a couple manifolds and lots of fuel but can't quite get the right setup right through the full rev range ,and have not heard of any turbos off the shelf that will work .unless nobody wants to admit that these hdt s will rev 6000 rm. So if the twin setup is going to do it ,I would seriously think about trying it . And yes I still got your number ,still got to at least drop by to show you the manifold at least . I'm thinking this is a good read post for some,at this point, I know I learn something ever time you post almost.cheers.

 

[gerg]

No problem wrong way, its all fun. Ok, so you have lots of fuel. Are you saying you want a compound set up that works to 6000rpm? Ok, let me catch my breath here... uhhhumm. Ok, so that would be a job not suited for a nurse and would not have good maners for daily driving.

But just for fun.
You could run a He351vgt and try to controll the surge, with a hy55v below which would carry you to 6000rpm at 25lbs... roughly. Or an he561 which can do about 50lbs boost to 7000rpm by itself, and id expect a hefty price on all this stuff. Controlling it is another matter alltogether. I would also add a very large external wastegate. Or two.

Honestly man I have no freakin idea as I have never mapped anything like that before. But the hy55v will run to 90ishlbs a min which is what you are asking.


By the way mods should look into MarchelleChang as he is a marketing bot. He only reposts what others post. Plus, I tried to friend him and he didnt respond, so I hate him and wount invite him to all my facebook parties.

Live in the now man... That design is old school. A single Gturbo running 30psi is easier and better .

 

[ForealBoreal]

Sweet jesus bigboy!
What are your kw or hp figures running 30psi into your 1hd-t?

Gerg your a wizard.

Wrongway, what chinese turbo are you running at the moment?

 

[TheBigBoy]

I have no idea lol.

 

[ForealBoreal]

i'm assuming you can spin the tires pretty easy.
