Twin Turbo Deuce

[dm22630]

Can you convert a deuce into a twin turbo w/dual smokestacks?

I guess have 3 cyl going to the 1st one & 3 cyl going to the 2nd?

Would this give you more power or just blow up the engine?

I was thinking of a matching exhaust on the drivers side.....

Hmmm, i dunno how well a dual turbo setup would work. But the dual stacks are doable, sasquachsanta has em, they look darned sweet to me. I know he did a writeup too. Happy searching

dont know about the twin turbos. i imagine it can be done if properly setup. But why not just split the exhaust pipe and run a second one to the driver side.

3 things come to mind.....

a) more power
b)louder
c)more power

I am sure that there is room for it.....could the engine handle it without blowing it up?

What would that do to fuel mileage?

OR.....

If I split the exhaust and had two pipes with one turbo.....would I lose any power/fuel mileage?

i know that on the cummins you can run a compound system with a small turbo that feeds a big turbo. some of those system run up to 75psi of boost but on a duece i dont know

RE: Re: RE: Twin Turbo Deuce

the question is not "can" you run twin turbos but why.

why? bc you can blow the stock engine on the stock turbo so why would you want to go to all the trouble to make it even easier to scatter the motor?

if you want more power turn the fuel up. if thats not enough then get a different motor.

If one turbo adds power without sucking in additional fuel.....then two could produce more power & push the deuce down the road and up hills at lower rpms??

It is late...and I am tired.

I apologize for my ignorance.

Thanks for the responses......

Start with the basics. You need a certain ratio of air to fuel in the chamber. The turbo pushes more air into the cyl. than the motor can suck in, so you can turn up the fuel delivery too. At a certain point, you will have so much boost and fuel, you will blow the cyl heads off the motor. Usually, you'll just get so much heat, that something melts first. Make more sence?

If I understand things correctly, a turbo doesn't add power without sucking more fuel. What it does is to cram more air into the engine, and thus allow you to burn more fuel, and thus get more power.

I think that two small turbos or one large one will have the same effect. You can only run so much boost before the engine blows. If the stock turbo can already boost enough to blow the engine as jwaller wrote, then adding another turbo won't get you anything.

I'm just talking out my rear end here, but it seems to me that twin turbos might make sense in a V engine where it may be desirable to have separate exhaust and/or intake systems for each side, but would just add needless complexity without any other benefit in a straight engine like the stock deuce engine, assuming that the existing single turbo can already push in as much air as the engine can handle.

Listen to Waller's advice, he races turbocharged stuff, know mapping and boost.

 

[dm22630]

RE: Re: RE: Re: RE: Twin Turbo Deuce

Ah....I am getting more of an understanding now.....

Multifuels that have turbos are already at max capacity for the engine & adding more will break things?

I am trying to be more mechanically inclined

But to a lay-person like myself, I thought it was like having 2 headlights instead of 1

Thanks for your insights everyone!

Usually, on a twin turbo stup, one is geared towards boost at low rpm, and the other takes over at higher rpm. Something to do with fan blade pitch and the size.

Yeah....now that I think about it.....I had a 2008 F-450 that had 2 turbos....one worked taking off & the other kicked in at higher speeds. It got a WHOPPING 11MPG! hahaha

Turbos really don't add hp by theirself. They add more air that lets you burn more fuel.

The turbo on a multifuel is a little different. When they had the non turbo LD-465 they smoked alot. They added a turbo to put more air to the engine so the air/fuel ratio would allow for a cleaner burn. Just adding the turbo didn't increase the hp very much.

Adding two turbos will just let you burn your engine up twice as fast. If you want dual stacks I would just "Y" off the single turbo outlet. That's how 99% of trucks with dual stacks are done.

I may be wrong, but I feel like the stock setup only "comes into its own" near the high end of the range at WOT from 2000-2500RPM. But I have never turned the fuel up enough to produce black smoke either. I don't get smoke at all in fact. In speaking with Memphis Equipment co. they advised me that making smoke for any length of time other than brief accelerations is asking for trouble. The deuce already has an unusually high compression ratio compared to regular diesels so pushing it real hard may not be such a good idea, especially if you have the old style head gaskets. I am aso concerned that if I turn up the fuel too much and lay into it at 1500RPM, I could bend a rod or something? Then there are mountains to be climbed..

Shooting soot all the way up the mountain would seem to be asking for pyro redline or worse. Having been a bit jealous of the black smoke from other people's deuces, I'd appreciate Mr. Waller's comments on this.

Can't resist. Turbos DO NOT make more power, fuel does, but, if you ask the Banks salesman, all ya gotta do is slam a big turbo, a different wastegate and different intake on your "turbo diesel" to make more power. Listen to Mr. jwaller, he knows what it is about. All that black smoke out of Banks and the likes engines is incomplete combustion and wasted fuel. Sorry, I usually don't rant...just ramble, but this topic tics me off only 'cause I have to deal with it on a daily basis with people who know nothing and believe everything they are told or read..motormone people. I could go on, but won't. Thanks for letting me vent, I feel better, sorry for yelling...guess you couldn't tell that I was. MV content..I fixed a USMC gasser forklift today?!

Here are some pictures of my stainless steel dual exhaust system. It was purchased through Dan Stigletz stigy44@elknet.net --- Tel" 414-305-1670.

I can't say that adding the duals increased power or effected fuel economy. The duals were added along with a new LDS engine therefore many things came into play --- too many to track the effects of only the impact os the duals. All I can say is that it sounds good, looks good (IMHO) and gets lots of positive comments.

Having the drivers side stack also makes it easy to see the amount of smoke that is being made. It's easy to see the contrail from the drivers side mirror.

Given the high compression ratio of the multis I would be afraid of the twin turbo concept. It also sounds expensive.

as someone pointed out in an earlier post the multi's in our trucks didn't originally come with turbos. the turbo was added later on in it's life to help clean up the exhaust smoke. so in essence the motor wasn't designed for a turbo. hence the high compression ratio(party due to make it a multi)

now what happens in a non turbo multi is that you can only inject so much fuel before you get to the max EGT. so you get to a point that no more fuel can be added without adding more air. when more air is added(turbo charging) you then may add more fuel. now you can then again run this combo to a point(about 18-20psi) when you will again reach max safe egt(about 1250deg F).

so yes if you have a turbo multi you can turn the fuel up till you get 1200 on a very hard uphill pull.

now with all that said; diesel smoke is Wasted fuel. if you are making smoke then you are pouring fuel and $ out the stack. smoke is unburnt fuel. Although it seems that with some diesel or mutilfuel designs you cant get to max egt without seeing some slight smoke. but if you are smoking so bad you cant see the vehicle behind you then you have the fuel turned up to high.

now all of what I have said only applies to diesel engines. Gasoline engines respond to turbos and fueling totally differently.

 

[scooter01922]

Want smoke????? Want to avoid detonating your engine???? How about you just put a fitting in the pipe just after the turbo and inject a spray of raw diesel , that ought to get you about the same results. Not sure if the EGT would be high enough to cause it to ignite or not, might not be enough oxygen. Lots of smoke, wasted fuel going up the stack as smoke and no worries about turning your multi into a boat anchor.

 

[WillWagner]

Scooter, if you did that, you'd have clouds of white smoke. Maybe Florida or Mississippi would hire you for mosquito abatement and that would help you offset your fuel cost
