Dt360 upgrades

Has anyone Delip these Pistons to lower the compression any? I'm going to balance the rotating assembly anyway.

This is Chris' engine, Swamprat on here. 2500, but it does need a few things. It also has the stuff I was missing. If I had only kept the Scheid 13mm p-pump, this thing would be running already.
I've bought others for 1000-1500$ though. I think 3k is kinda steep for an engine not made for 20 years. There are bus yards full of the things. If you're interested I've got a lot of contacts for them so let me know.

Those numbers sound much more reasonable. I'll most definitely hit you up when I'm ready to pick one up. Thanks!

Nice! Do you just plan on parting the rest of the truck out or scrapping it?

Have you guys looked into AFC Live for tuning the p-pump setups? I would assume it would work for these DT motors, but maybe they are different from the Cummins/P-Pump setups.

I have not. I'm going to figure out how to put a pickup sensor in this one for PCS input speed. Might add this to the list.
FYI, once this is done it will be for sale.

Parting it out but if it sits long scrap yard it.

It's has new virgin rubber on the front and two new tires on the back. Should come out okay on it
Truck shows 69k but has reman motor and trans.

Anyone know of anyone making a mild cam for these and not an all out tractor pulling cam?

jimdawg185 · Feb 1, 2016

Colt Cams can make one

Corey put a completely stick long block in his dually. Only changed valve springs and pushrods. Put a tuned p pump and an S480 on it and that thing is a beast. I drove it and was completely amazed.

I know I don't need one but thought if it was reasonable and I am already into this motor I would. Plan to clean up the ports on the head while it's off.

Is he running a 480 as an atmosphere for his stock turbo or running as a single

What's the smoke output like down low?

I thought I was a little crazy wanting to run a 475 as a single. But I'm thinking I might be okay now.

It was pretty smokey, but not like it was struggling to spool. It lit very well for such a large single. So did all four back tires...

It's all in the pump tuning and injectors. Carson put all that together for him.

Badazz! You guys need to look into afc live. It would be sweet if it worked on the dt. The pro model, or whatever it is, allows you to have two different running setups. One for street and say one for all out. Through a hp turbo on his setup and i bet it would be crazy. What does he have the pump timing set at? If only they'll made a dynamically timed p-pump setup. Nothing crazy, but something that would give you 3 to 5 degrees of advance.

That's always been the advantage of common rail.

I think his timing was in the mid 20s maybe higher even. I've heard 30 plus is used in the pulling engines.

Afc live is interesting. Pretty simple concept and I think execution. One could use a boost controller off a car to do the same thing ramp fuel with rpm and have max boost setting for the same money. And not have manual knobs to turn. I'm going to have to play with that idea once mine is running. It would be nice to be able to set it to max 30 psi boost for towing and program a egt fail safe limit to pull fuel if egt breaks a certain point.
