I think you could do it to any vehicle if you have the know how and fabrication skills. Oh and some money never hurt.

 

i wonder what it would take, i can see hooking the turbos together, but the pedistol and exhuast would be hard...

 

heres a guy that actually had a done a compounds on his obs and he's done a triple turbo setup DIY-Injectors.com click on " our friends websites and at the botton of the list its say dzljim.com then click on the black truck

 

If you've got some decent fabrication skills and the proper tools to do it it's not hard to fab this stuff up. The harder part is going to be actually selecting two turbos that complement each other so that they both run at peak efficiency.

 

That right there sums it up. :thumb:

Some examples of homebuilt twins on a 7.3l: Twins!

BTS twins are for the Big Boys. I doubt anyone interested in building their own stuff thinks they can compete on the level of BTS and/or Zane at Wide Open Performance...

Call brian or cale at BTS.they made zanes and cales.and the numbers say it all.:thumb:

 

I just want to do something, with my stocker and maybe the GT38r, i guess i will have to studdy them alittle more... off the top of my head i wouldnt no how to do the part where it mounts to the motor on the second.

 

THERE IS A GUY THAT PAIRED A GARRETT 38R AND A GT47-88 TOGETHER AND MADE A YOUTUBE VIDEO OF IT

YouTube - Powerstroke Compounds on the Street

 

okay guys. when my gt38r ever shows up, i am going to try and figure that out. if anyone has any suggestions or ideas im all ears. and hopefully i have enough room under the hood.

 

A 38R with a stocker would be pointless. The system will only flow as much as the biggest turbo would by itself. It's what's feeding the system. A 38R will spool very well on these engines so there is no point in having it be the big turbo in the system. You'd want to add something a lot bigger. Like the GT47 or something similar. This is what I was talking about the hard part being knowing what to put with what. You need to find a turbo that has the flow capabilities you need then compare the map of it to the map of the smaller turbo that you want to run and find two that will compliment each other rather than fight with each other. I'd suggest picking up a book entitled Turbochargers by Hugh Maclnness. It goes over a lot of theory and has a secton for sizing compounds.

 

I have that book. Good info, a bit dated.. but good. :thumb:

 

Red,
That's Charles that built those for his own truck. The guy is pretty bright and definitely did his homework and ended up with a great set of twins.

cchase,
I have a bunch of pics on my site in the link above of everything you need to know to build twins. What else do you need to know or are confused about? Don't complicate things, it's actually pretty easy once you get a grasp on what's involved. The hard part is making it all fit under the hood. (aside from the previously mentioned 'Hard Part' of making the 2 work well together.)

GTS,
Just like you said that you don't need custom programming to run custom injectors, I could say that any turbo that flows more air than the stock turbo will work for a twin set up. It might not be optimum, but it'll be better than a single. Even with my cheap, crappy HT3B feeding my stock turbo, the difference was amazing and quit fun to drive. The HT3B only flows like 1000 cfm, the 38R, I was told, is a hair more than that. :dunno: Haven't confirmed it, though everyone that has one that I've talked with gain about 100 hp with it so I'm guessing it moves some air...

Jim that is quite a stretch to try to start an argument.

The HT3B is significantly larger than a stock turbo or a GP38R. There are a lot of guys running those as twins on Dodges with an HX35 or HX40 as a small turbo. I know of one guy making high 500hp range with an HX35/40 small turbo and an HT3B as the big turbo.

I guess if you wanted to be very technical anything larger than stock might show you some slight gains. But you'd need the added fuel to utilize the extra air or it would be even more pointless than it would already be. Especially when you have a turbo such as a GTP38R that spool as fast or faster than a stock turbo as it is. It would probably make for a slower spooling set up due to the added restriction in the exhaust of the 2nd turbo until the 2nd turbo got spooling as well.

This is completely different than needing a custom burn on your chip for custom injectors.

 

there will be fuel for the turbos, the trucks getting stage 3s next week.

I guess Jim, what i am a bit confused is, yes how to make it fit, and 2 which turbo would you want to feed into the other?

 

The big turbo will feed the small turbo on the compressor side. The exhaust side will go through the small turbo first then the big turbo 2nd. To make it fit you just got to find a good spot for the turbo to live and plumb it in. Some have removed one battery and put the turbo in the front corner of the engine compartment. Others have squeezed them in tight on top of the engine. You could look for some pics of what others have done to get some ideas.

Something else to consider is you will want a decent waste gate on the small turbo. If you don't you will likely toast it from overspooling it. Generally the small turbo can't handle the larager amount of exhaust going through it so you need to have a way to bypass it. Depending on how big you go the stock waste gate won't handle it. the best gate to get would be a Newgen from Turbonetics but they are EXPENSIVE!!! But they work sweet!

 

your not to far from me. the diesel performance guy who built my truck does twin setups on 7.3's and says its pretty easy on them. now the 6.0's are alot harder to do. if you want, i can give you his # and heres a pic of his new truck with twins. sorry for the crappy pic. it was with my cell phone.

 

dang!!!
is his exhaust 4-real comeing out of his fender?

 

Thanks Jeff, I would love to give him a call and ask him about this. I have a very nice diesel shop close to me, but i havent had the chance to ask him. I like to go into things with all posible information.

 

yeah thats for real al right. just wanted to be different. he took 2nd place at autorama here in michigan. truck also has 2 stage nitrous. heres another pic of the truck

 

that red bull drink is the reason he took 2nd lol
it gave it wings lol

 

I am thining about stacking a gt35r and something like a gt42 or a t6 because i am a sick person. But my personal goal is to humble a friend of mine and his stacked up jacked up dodge on toyo 40's running 3 chips and a hybrid 70mm turbo. I mean thats just sick... its still a dodge!

 

Does that guy in michigan have a website?

 

Could a set of 08 twins be used or one of the turbos..got a set I'd like to use either by themselves or with the H2e??

 

Just the CI difference would make me say no.


EDIT: See above post.^^^^

 

Well you are taking a set of twins designed to work well on a 6.4L engine at stock power levels and expecting them to work on a 7.3L engine with completely different air flow requirements at over the power levels they were designed for. Probably not going to work to make good power with. Might work OK to make a little over stock power with a quick spool up but the stock turbo does that OK.

 

im pissed I cant even find the dang new issue around the school or gas stations. WTF. dont mean to hijack but 07stroker thats a beautiful truck ya gotchaself
