Weren't you supposed to have the twins in Today? Must not be done or you would have said something.

Yes the TWINS are in!
But.
We have a lot of fuel to tune with.... soooo DTT has booked some Time at a sekrut Sqwirl Locayshun to du sum tuning in.

Will know more soon!
Nathan was a bit shocked! Lots of Fuel, Lots of Air= 1 Bad Max!

Hows the head gaskets holdin up? Whats the max boost you have hit? Might be time to get some studs just in case........This is gonna get very interesting.

I do not know
Truck is still at DTT getting dialled in.
Something about a lack of fuel in my truck:muahaha: :muahaha: :muahaha:
ahh well. it will not be long now.
Powdercoated and Signature series Twins.

Signed and numbered by Nathan and DTT. I requested a few special touches so when the photos can be released, it will pay homage to the fabricators and designers who made TWINMAX a reality.

:nopics:

set the blow off valve at 60 and hang on, we have to know the limits, lol

ahh well. it will not be long now.

THATS DAM FUNNY!!:lol:

We will get a new truck :D Did you have any doubt? :p:

He just has make up his mind which one he wants and I thought Women where bad :muahaha:

I found a Victory Red 4 x 4 one tonight. But it's a Chevy so I don't know what kind of deal we can get. The GMC is where I have been able to get good deals in the past..

Congrats to the both of ya:ro) IMHO go for the GM they look better:exactly:
Im up for addoption n lookun for a VETT:muahaha:

Well I will trade you for my Mini-van :eek: :help:Straight Across?):h

Ummm.. that is a paradoxical question if ever i heard one...
frying pan or fire... hmmm

I'll think on it
ok
Thoughts over

NO!
I'll keep the dually:lol:

Well ordering one is also a option :exactly:

As far as my Vette goes.. My wonderful :hail:husband towed to the Trans shop for me again today. This time a different one.. Hopefully it will be fixed once and for all.. I have a race in less then 2 weeks :eek:

Wise Choice :HiHi: :HiHi:

The head gaskets will hold fine. I've run WAY more pressure than those twins will ever be able to deliver. It takes astronomicle pressures to blow them (it was and accident). And by the way, those components in there are much stronger than most think or believe.

Yes the TWINS are in!

That's awesome. I know this year is going to be KickA$$ with the Duramax hidden secrets they are finding.

Lets hope all goes well and it is a dependable setup. If it is dependable, there will most likely be a lot of orders for them (including me!) Juice, let us know the results when you are allowed to!! Good luck!

Dan

Wise Choice :HiHi: :HiHi:
Unless..... you know what Kat, I would consider trading you for the Ford. Left to my own devices I believe the most equitable 'Straight Across' Trade would be for me to swap the Ford for the Vette! Heck I will even throw in a full tank of fuel! Bill tells me he will accept the trade. What a deal!
I bet they are both very useful in Snow country!

Get back to me Via PM to work out the details;) ):h

DanI have every confidence in Nathan's ability. He has built a lot of twin setups, both on 12V and HPCR Dodges. Boy does his truck (3GRam) pull!

Juice - let us know if you need anything---you know how to get a hold of us!!

Juice I went bye the powder coaters and they showed me a nice shade of pink for your truck.:eek: Remember you said surprise you.:badidea:

Juice, I think the fellas building the truck will do a great job.:thumb: I do not believe you will need to worry about the heads. However, I am skeptical of the rods. I'm not saying they are garbage, it's just ..... long term @ XXX HP that gets me.:banghead: Super Diesel, can you comment on this?:confuzeld

Will Do Bud!
It'll be a good year for the DMX!:ro)

Yes Super Diesel Tell us more.. How much did it take to blow the head gasket?

We have fracture split PM type con-rods right? Do we really need to address this yet?

Thanks,

Brayden

Ithought our Rods were I beam steel forged and fracture split.

The 6.0 Ford is PM

Not sure.. on that.. Maybe that is why some of the dieselstop guys were talking about "windowing the block" on their 6.0L's.

Hmm.. :)

I'm not sure either, but it is metallurgically possible (and practiced for many items) to press and sinter a powdered metal preform and then forge that for densification.

Still haven't answered the head gasket question.. C'mon spill it SD :)

There is a difference though.
Boost is always 'Actively' present in the cylinder when the valve opens.
Drug power is only active when it starts oxidizing (burning)

For a given IMEP N2O and C3H8 and CH3OH exert less cylinder pressure until ignition. After ignition Cylinder pressure spikes quite rapidly
Turbochargers on the other hand Exert their force on the cylinder from the moment the intake valve opens until it closes and ignites, but the ignition event is less stressful than drugs because the burn rate is of one fuel only... not an additive of others with differing combustion charecteristics.

Now, Drugs can be as dangerous as excessive boost. 'pooling' in the manifold, 'pooling' in the cylinders and a few other quirks.
Mind you these are worst case scenarios, but it does help to explain why a lot of diesel owners eschew chemical oxidizers and power adders over plain old #2 Diesel Fuel.

on Edit: This is just a general observation (seen on gas and Diesel engines)... if someone would like to revise or correct me on this you're more than welcome... I'm here to learn too!

Ahh.. Didn't know your little accident involved drugs..


Rumor around here is that the heads are good to 60 psi or so right... ?

Thanks,

Brayden

Thanks,

BraydenI have never used drugs on my diesel (other than Stanadyne)
The heads might be good to 60 PSI.. nobody really knows for sure.
My worry is not the heads at this point. It is the 3 piece manifold setup on the LB7. Stud mounted yes, but the sealing surfaces are villainously small (especially the V-split).... can't really O-ring them either. Might need to make an improved casting once the heads are studded, because that will be the next weak link in the chain.

You should worry about the heads!

You should worry about the heads!Nahhhh):h
What me worry?:help2:

OK... call ARP.
I know of this shop up in Canada that's dying to do a DMX headgasket):h

Piers gonna do that for ya eh?

Sorry about the drugs confusion.. Thought since you were explaining them, that it was from experience.


Sorry for the thread hijack.. Thanks for the info..

That's funny right there.):h

They are O-Ringed - I'm looking at a set as I type. ARP told me that the tensile strength of the factory stretch bolts exceeds the material (8740 chrome molly steel) they would use to fabricate the studs is 170,000 psi.

You might benefit having a fine thread nut on top for more accurate torque if you o-ring deck the heads and the block, but in a stock replacement application, the cylinder head configuration requires torque angle (stretch bolts) to have an accurate compressed gasket thickness, which is thred pitch divided into lenght of bolt...and so on with the stock gasket being steel shim type compound gasket at .022.

Receiver groove machined into the head and block, then custom cylinder head gaskets while maintaining a compressed thickness to keep compression ratio high and quench area substantially cool... you would be spending a LOT of money (trust me, been there, done that), or you could just go with a copper head gasket, stainlesss steel wire o-ring deck, block and cylinder heads thinnest gasket available for stamping purposes (crush is .039-.041) which would lower your compression (which isn't bad if your running 80 pounds of boost).

But in our world, we want 28:1 wouldn't that be cool - not too far out of reach combined with 500 cubic inches. Confused??? I am.:confused: wait......did I say twins?............................................ ...............................or

Good Post Tony, good post.):h

That was actually Jen---If it would have been me, it would have been a little more (how da ya spell...) technical.:joke: LOL!!!

Cue-'does' to Jen! :thumb: :thumb: ....... uh, who's Jen? :confuzeld

the wife

So you're saying that yours are O-ringed?

I'm familiar with fire rings, aka stainless wire and a machined groove. This is usually a better alternative to o rings.. You say you have looked into this or have not?

Your post was kind of hard to understand, not content wise. Lot's of info to spit out and fingers only move so fast.. :)

Thanks,

Brayden

Wow I just learned a lot.. I think anyway.

So when Juice blows a turbo now, he has another one in line to fall back onto. Or does this mean he will blow two at a time?


Hmmmmmm.................. :think:

Ounce of prevention..........you'll find out.

Yea, like I said, you need to worrie about the heads, they will melt too and have massive cracking problems just like they said. The head gaskets and rods hold well into the 800s+ if no solid liquids are introduced. Liquids don't compress (fact). The problem lies in a few other components right now. It's not like it is a race engine though. Compleatly different animal.

Sooo, what makes valves float? ........

Sooo, what makes valves float? ........Water?;) :lol:

Take the seated height valve spring pressure and divide it bythe radius of one intake valve squared and multiplied by Pi. ie - lb/(pi*r^2). This will tell you how much boost it will take to unseat the valves.

How many PSI is that?:p:

Beats me. You can find out either with a pencil or piston though. ;)


My guess is it is a non issue due to the small size of the intake valves.

i talked to a fellow last night from newyork, he has a buddy that has been runnning twins for close to a year on the duramax, he had put them in himself, he made additional 60hp with them and temps were cool, a few months ago he added propane, with the large tune and i guess she is a whole different animal now, had seen close to 100hp gain with just lp, i guess enought air to burn all the fuel, will be sending pictures of the setup, might have to look at some drugs juice, and keep the good qualities of our fuel system, i think it was a powershot system he said, thanks fred

I told juice I got drugs here that I took off my dodge.:ro)

stefan just put them on, see if he feels the diference, lol
are you going to make it east bound for sat. or to busy, let me know, thanks fred
