On the program they are building a suburban up to look like a Hummer H1. Today they went ove rthe engine, a Banks Duramax Twin Turbo setup, one turbo per bank. I had seen a promo for it earlier this week, so when I talked to the Banks shop this week to order some stuff I asked the sales guy if Banks was going to come out with a twin turbo kit. The sales guy told me no way. Well on the show they said that the kit was going to go into production. Any thoughts?

Just on principle I would like there to be more stuff out there available to us diesel guys, even if I probably could never afford it.

Saw it. Ford sidewinder? twin turbos. said 750hp and 1000tq. all that cash better deliver more than that.
Gail said smoking is wasted fuel and not cool. what-eeeevvvveeeer.

Ported exhaust manifolds, new split intake look like good parts.
split intercoolers. interesting?

Someone send me some twins for "testing" please.

I watched that whole show just to hear how they planned to control the Dmax without using ALL the stock wiring harness and dash, etc. Of course they never mentioned that little detail. :rolleyes:

I doubt that split intake will fit under the hood of our trucks either . . . all of that stuff looked like it was WAY more for show than for go. Slapping on a pair of "upgraded" 7.3 Ferd turbos instead of turbos designed and matched to be ran as twins??? C'mon . . .

Unfortunately, I wouldn't be surprised if this becomes one of those infamous TV projects that just vanishes from the program after a couple episodes.

You prolly right willis.

I watched that as well today..I am very interested in some numbers when they are done.

did anyone notice the stock Duramax intakes?? looks just like the inside of a valve cover.. I wonder if there is any benefit in having dedicated ports like his setup versus the wide open channel. Seems like if you have some direction to your flow it would be more efficient.

btw..I think he said that all the smoke was wasted power and just for looks

That was it. I was close. LOL

I'm thinking that if he does come out with a twin turbo setup that it will be like his twin turbo gassers. You can buy the engine already setup, but it's up to you to get it to fit whatever you are putting it in.

By the way, as far as controlling it I remember reading on his site that they licensed a copy of the actual software that Bosch developed so that they could change any of the programming that they wanted, even had a Bosch engineer come out to teach them how to use it. He'll probably come up with a prepackaged setup customized just for this setup.

I gotta admit though, I can see a lot of applications for a twin turbo gasser if you have the money, a lot of hot rodders will customize a car to make an engine like that fit, not totally sure about diesel guys, most trucks look pretty stock, even the fire breathers.

You have to remember, Gale is known for reliability. The hrspwr and trq #'s are most likely #'s that can be held at continuously, not intermitionally. Can you take your turboed, chipped, propaned, nitroused, motor and hold 750 horse all day without a meltdown?

Course not. Point taken

Sorry about two posts, something screwy happened.

May have been an old episode, but did anyone see on trucks were gayle banks built the twin turbo'd DMAX? They completely redesigned the top end, and were talking about redoing most of the engine as well, and he only expected 750hp and 1000lb-ft of torque? I just thought that sounded kinda low for a set of twins under the hood. And I'm also guessing that was a lb7 engine considering the lly's have vgt's, or vnt's.

It was a new show, funny they said it is the first Dmax with twins. I missed some of the show, so I didn't get the whole story.

yeah banks said the first DMAX with twins and I kinda laughed, but thought maybe it was an old episode.

They were taking an old suburban frame and putting an H1 body on it with a Duramax/allison combo in it. Banks goes through the whole prototype process and mocks up the twins and says that he will offer the twin setup, but he mentioned going through the entire bottom and top end plus the twins. I'm guessing it would be a whole new engine, basically a crate motor from banks. Probably cost a fortune, and the power output for that much work was kinda weak.

Gale claimed 700 hp and 1000 tq. and they freaked on Extreme 4x4 about how it would be so bad....

Wow, they need to join here!!!!

My guess is a $10,000 option that doesn't do much..

I think 10g's is low balling it. I've heard 11g's for a stock crate motor, plus all their bull**** on it. I was thinking 15-20k for a Banks DMAX. I'd like to see him try and sell it.

By the way, as far as controlling it I remember reading on his site that they licensed a copy of the actual software that Bosch developed so that they could change any of the programming that they wanted, even had a Bosch engineer come out to teach them how to use it. He'll probably come up with a prepackaged setup customized just for this setup.

I did hear them saying something about using Bosch's new 32 bit ECM. The #s still aren’t that impressive.

750 hp on #2 only, that would rock if it has a great power curve. Can you imagine having 500+ hp from 2,000 rpm upto about 4400 rpm. (Not that this engine would do this, but we can dream, right?) Now that would be a killer engine.

I thought I read somewhere that the Banks race truck with a similiar setup was over 900 HP. Maybe on the Banks site. I'll have to go look for it. Either way 700 HP that will run a few 100k miles (prividing it would) wouldn't be too shabby at all, although i'd be real interested in what they would need to price it at.

Edit: I was wrong... must be cunfusing engines. Here's from the Banks site.

Engine Output:

The Sidewinder D-Max Type-R tube-framed, road race truck engine has a power goal of 500 lb.-ft. from 2,000 rpm. The race engine has a power goal of 650 bhp with 5,000 rpm being the Banks-imposed redline.

Wow this is funny...I was either watching another show or I just paid attention...

It was a dmax, not a ford.
He said they using the same turbo that they use in their sidewinder kit for the ford, not ford turbos.
He went over other mods that are/will be done like beefed up bottom end and valve train.
He said they'll be using Bosch fuel system programming.
He said smoke wasn't cool.
The goal is 700hp 1000ftlbs reliable power, the look on his face when he said it was sarcastic, as in it should do more.
No doubt, this will be pricey, but why do you guys doubt it? A big company with the money and resources is finally taking our beloved dmax to the next level and you guys are dogging it? You really think with all the work and $$$ Banks has tided up in this it'll just fail and be gone? That's just stupid IMO. Its projects like this that get more people involved and more parts made available. I’m sure you guys are right though, it’ll just go away…you guys sound like you should be one a Cummins site, or maybe nick will hire ya when he starts his Toyota/ Nissan forum to be mods.

Has anyone else done twins on a dmax? I know there are staged turbos out there, and I’ve seen a pic of a prototype twin setup, but has it been done?
......

Blue you are miss-understanding my point behind this completely. I'm not saying banks doesn't do their homework, or that their product is junk, but they are basically rebuilding a DMAX from scratch and adding twins. Those two points alone are going to make this a pricey build. So I don't see the point behind this. There are several people on this forum that are running those power levels safely with a rebuilt tranny and a few other mods that cost probably half of what the banks kit will cost.

My point behind all this is, That kit will be expensive, and the gains are not that substantial for that kind of cost. The same power levels can be had with programmers and upgraded fuel systems. Plus banks immediately takes credit for being the first to come out with twins on a DMAX, uhh maybe commercially?

One other thing I noticed or maybe I missed, did they say anything about the tranny????

They said it's a hillkiller tranny, not sure what that is...

Who made twins?

here's the trans..

I'm with Ox on this. 750Hp may not sound like much but banks always builds conservatively, not the most horsepower but very reliable horsepower.

Will it be pricey, yeah, not something I will likely be able to afford, but believe me, there all kinds of people with more money than they know how to spend, will they sell em, you betcha. Heck I even heard of someone in SoCal building a performance boat powered by two duramax engines, is it logical? I don't know, is it cool? definitely.

So cudos to everyone brining the Dmax more power, including the twin turbo pioneers like IdahoCTD, and others I'm probably not aware of.

Anyone else for more power? :grd:

I find it quite interesting why the torque numbers are so low for the hp. Either the turbos are way too laggy (most likely the case when you use half the cylinders to drive a turbo bigger than the stocker run off of 8 cylinders) or they are making high rpm hp. Neither one is a match for a H1 knock off. I thought they said something about it being a rock crawler since the are using two x-fer cases. Nothing like taking the torque out of a high torque motor for rock crawling.

Banks is a big fan of sacrificing Torque for hp on diesels, and I don't really understand that, He prefers to rev them higher to make the hp, and cut back on the torque required?? Isn't that basically a gasser?

More like a glorified Hypertech
