P-pumped Duramax?

I'm gonna need a towel. LOL That's truck porn if I ever saw any!! So awesome Chris! Thanks for sharing! :rockwoot:
 
Thank you so much for the details an pictures Chris!!!

Really hope to see it run at an event Im at this year.

Care to give any details about the truck this badass motor is going into?!?

Would love to see a V8 win the mod class this year!!!! GOOD LUCK!!!
 
that is one sick piece from the drysump on up

the cost, even though your doin most of the work n fab must be HUGE!!
 
a stock duramax block casting will hold 2500 hp??

or am I missing something?
 
that tractor was pretty sweet. The first pull didnt go well but it just needed dialed in.
 
Very interesting, what kind of pressure does this pump supply to the injectors? If you manage to get the hp you are stating that would be something for a stock dmax block for sure. Congratulations and I looking forward to watching you progress. Would have loved to see it at TS, but maybe I get a chance at another event. Thanks for sharing.

The rules state that our engines can be no larger than 460 cubic engines, and the block must be from a 1 ton or less pickup truck or a dimensionally identical aftermarket replacement. It has to accept and swing a stock crank.
We are at this time planning on using stock block and head castings.

Yeah I knew about the blocks and needing to be identical how everyone is switching to Billets. I thought it had to have a stock crank though. If it needs to just accept one then your straight. Ben Miller ought to be able to get a custom crank try to squeeze a few more inches out of it.
 
I think the idea is that the high rpms will allow less cylinder pressure and keep the engine together. I know that Banks isn't running a ton of cylinder pressure, they're just turning 5,500. At 7K keeping the crank stable will be a problem, but it looks like Chris has addressed that as well as he can with the stock stuff. Don't know about a Dmax staying together at 2500 hp, but I know of one that has made c.1,700 at the crank and kept it in one piece.

The idea behind accepting a stock crank, is so you can't move your bore centers out much.
I think Bens engine is right at the limits as it is. It is better to go with bigger bore first in most cases to facilitate bigger valves.

Absolutely. But its not just the pressure, its the amount of time the cylinders see that pressure. I dont know if it will stay together or not either, but the duramax block is very promising. I have to say that the engineering and design teams that worked on the block did an excellent job, and that gave me a great point to start with. And if it doesnt hold, I can allways call up LSM and order a billet block, but i'd rather not. Being independently funded has caused me to take long enough on this one.

It's not like it has to stay together for that long, just 300 ft :rockwoot:
 
What parts are you waiting for Chris?

When there's a new thread about your truck, I _____ in my pants. LOL

Think Lonely Island song :hehe: If yall don't know what that means, search for "in my pants Lonely Island" on YouTube and prepare to laugh. LOL

Turbos, Crank, Rods. I can't hardly get anyone to call me back. I leave messages, I have the money for the parts, I guess no one likes money???

How many turbos are you planning on Chris? (If you'll share...)

Three. Plumbing on this truck will be a nightmare, like ten pounds of crap in a five pound bag.

What kind of boost and drive pressure are you looking to make, and also still curious about the pressure one of these pumps puts out the the injectors? Thanks for the info.
