Twins, on a Ford...So glad I'm twin-turboing a Cummins!

[NPloysa]

Well, not now, but if and when I do, Thank the Lord I have the Cummins to work around and not a PSD!

Ummm... wouldn't it be easier to run 1 turbo per bank instead of running them in series? Sure, you lose the compound effect, but you could make up for it by using BIG turbos. Then there'd be no need for all that ridiculously complex piping...

Beats me! The roller coaster piping made me dizzy though!

All i can say is that guy must have had a lot of time to waste.

 

[Mark_Kendrick]

It looks like he could have reclocked the turbos and used a lot fewer bends . If he has fuel it should run pretty well.



I wonder if he'll dyno it.

 

[mjoppie]

mark, thats exactly what i was thinking, a lot less bends and easier to work on. where do you think the oil is draining to? looks pretty complex but yet not to bad at the same time. my cousin is going to attempt the same thing someday.



but at the same time isnt these the same guys that were bashing the cummins about having to use o rings and spending $25,000 for twins? i seen his head and block were ringed. oh well, guess they will never get past nipping at our heels at best. :-laf maybe someday they will get a stroker to get 20+ mpg with 400 hp..... yeah right cant do it stock.

And I though I was hard on the ford boys :-laf:-laf

The whole point of sequential turbos is getting fast spool up and lots of top end. a turbo for each bank equates to a big single. . low egts/good top end or spoolup, not both.



with compund (twins is a bit of a misnomer) tubos you get your cake and eat it too.



fwiw,

Hadn't thought of that...

Exactly. My brother's Bi-Turbo Audi S4 is cool in having twin turbos, but they are true dual turbos, and not compounds. One turbo feeds each bank of cylinders. Great idea for packaging and performance in the car, but probably not a truck.

He should of just dropped a 12 valve cummins in it.

this statement should be attatched to every post about any Dodge, Chevy, or Ford truck that DOESN'T have a 12v in it!





as for the twins? I'm not saying mine are show stoppers or anything, but the phrase "hammered ****" jumps to mind :-laf

Forrest,

You gotta stop by one weekend. I'm in Dallas during the week and 40mi S of OKC on the weekend... Lindsay, OK 73052.



Later,
