Compound Turbo LBZ Duramax Startup

I was asked by a college buddy to take a vid and post it up. Here it is, it starts, I walk around a bit, and it whistles.

Poweder coat the cold side, ceramic coat the hot side

bad ass man. nice truck

[@kilo6490]

@HotRodTractor so you dont have any numbers? and no, compound is not the same as sequential. With compounds, the first charger compresses the air, and sends it the the second charger which compresses it more. In sequential twins, like the MPI kit, the smaller primary turbo, usually the stock one, is used for low engine speed situations when quick spool up is wanted, then when engine speeds increase the primary charger is bypassed completely, and the secondary charger is used. Not the same. lol

[@HotRodTractor]

I haven't gotten to the where I want it yet to even take it to the track, but the tow tune is nothing less than badass

[@HotRodTractor]

@dieselfanatic13 No - its 4" directly off the atmosphere turbo and jumps up to 5" as soon as there is room and its 5" the rest of the way - no tip.

[@HotRodTractor]

Ummmm.... its my personal tow truck :D It is an MPI kit, using a larger atmosphere charger than the standard kit as well as a Danville modified VVT charger in the valley. Its a nice smooth running tow truck.

[@HotRodTractor]

Yes its my Daily driver. I've got it set up so it makes about 2psi at idle, and at cruise the atmosphere turbo is making about 2-5 psi so as soon as I want it to go... it GOES.

ill have efi soon. rite now i have a van aaken smartbox. it gets me decent mpg's but i like the ability 2 change more wit efi live.

[@kilo6490]

@kilo6490 well... some people do call sequential setups compounds and vise versa, but it's not exactly accurate and confuses people.. A true compound or staged kit is different then sequential twins... all im saying here really, is that the MPI kit is not a compound kit, it's a sequential twin. There are 3 types of twin setups: Parallel, Sequential and Compound(Staged)...

[@HotRodTractor]

@kilo6490 I don't have any "big numbers" because I have never tried - I built this truck to pull a 36' gooseneck with and it does that in a tune that makes about 400HP to the wheels day in day out. And you are WRONG - this is a compound turbo setup - IE there is an atmosphere charger that compresses the air and there is a high pressure charger that further compresses the air. So by your own definition this is a set of compounds - to my knowledge no MPI kit works the way you think it does.

[@HotRodTractor]

Don't know what Dmax your talking about that was at Marysville other than my tow truck that stayed hooked to the trailer the whole time. I'm not really a Ford man, I'm a horsepower man!

[@HotRodTractor]

@kilo6490 - Ummm sequential = compound - its the same thing - its not like I called it "twins" which is technically parallel chargers. I can make up any numbers you want to hear. LOL

[@HotRodTractor]

Nope not Industrial, that is an MPI setup.

[@HotRodTractor]

Yes its EFI live. No point in running anything else

[@HotRodTractor]

@dieselfanatic13 Huh? There is an exhaust on it..... don't you see that 5" exhaust pipe in the video?

[@aguyfromalabama]

industrial injections twin? im waiting for the lly twin kit!:)

[@kilo6490]

@HotRodTractor you are right. i am wrong. DAMMIT! ha

[@JasonWaterfalls13]

How do you like the MPI set-up? I know their are a lot of guys making great power and running sub-12 seconds quarter-mile times with MPI twins (thank you Diesel Power mag). Every dyno it? 1/4 or 1/8 mile times? Other mods? Great truck, love to see more of it!

[@aguyfromalabama]

daily driver? how does it handle?

[@9MinuteMotos]

hey i think i have the same rims on my dmax... i painted them black tho

[@EasternAggie]

thats an amazing creation lol. what kind of times does it run in the 1/4?

[@KB3MMX]

UM, yeah.... RWHP !!

[@kilo6490]

not trying to be a dick, but not a compound. MPI's are sequential twins. haha Sick kit tho, i want on too. Currently running a fleece cheetah, gonna use that for my primary charger. Have you made any numbers yet?

[@blanders72]

What kinda mpg does it get having all tha extra power?
