I believe his name is Ben? I talked to him a good bit and pretty much crawled into one turbo and out the other at Indy. He was quick to clarify that it is NOT a mack pump. It is some kind of P-pump that never had anything to do with mack. He said ask Dan if you want to know what pump it is.
Heads, crank and block are 7.3 though.
It is a very cool truck. I love hearing a 7.3 making power up top.
After watching the video in that link it doesn't look like Double Overtime unless that was early on before he did a lot of work to the truck itself, like light blue paint, 05 tilt up front clip, wastegate dump through the hood, first stage compressor inlet velocity stack poking through the grill and all.
That's not "Double Overtime". And it's surprising to see the single stage turbocharging on an engine like that. But very well executed. Beautiful layout on the intake/charger setup.
To the post just above this one:

So it is a Mechanicaly injected truck, but NOT COMMON Rail? (Suppose I need to learn a bit more about anything NOT HEUI,,lol
And that vid from TDG wont work, TDG must have CRASHED HARD, because it has been down alll freeeking day!
Trying to find out something about a Dodge for a good friend of mine in the Guard, he got a good deal on a 94 12valve, and wants me to help put gauges on it. Need to know the best places to install the trans temp, (auto) Boost, and of course which side (Drivers or passenger) is the best to do the Pyro, pre turbo,,
Drill/tap the manifold? right above the output I suppose?
Since the Cummins is an inline engine you will have to install the pyro on the rigth side of the engine unless you turn the engine around backwards. Install the pyro pre-turbo, easy spot is just behind the turbo mounting flange. There are extra 1/8" pipe thread ports in the intake manifold for the boost.
High Pressure Common Rail are not mechancial injection systems. The two trucks above use mechanical injection pumps similar to the one in your friends 94 Dodge (that was the first year for the P-7100 pumped 12v).
