As well as lighter and more compact.  But the German engines tended to rely on injection directly to the intake ports, after the compressor stage.  The inlines and V's, in any case.

 

Pretty sure the DB 601 was direct injection, and not a port system.

Don't have that one anymore, but it's hopefully in good hands.

Tell me you found another 7.3 powered truck before you sold that one! Unless of course you had no need for that size truck anymore. Imho those 7.3's are way more engine than these emission motors.

No need. It served well, but I no longer had a use for it.

That depends on your definition of direct injection.  Direct injection could mean an injector that sprays directly into the combustion chamber and basically being a part of the chamber, or it can mean an injector that sprays down the inlet port directly at the open valve and the gap around it..

Okay, "I'm pretty sure the '601 ejaculated it's fuel right into the cylinder. "

And the dust. It's like very very fine lapping compound.

Fair enough, then.  Definitely after the compressor stage.

Same here as well, just my windshield alone looks like it has glitter in it, I replace it twice a year, my insurance allows for 3 replacements a year.

Why would you want a N2O system in a tank?

Engine boost, like turbo boost.

Tank engines aren't pulling high revolutions.  3,000 rpm is a screamer for a tank engine, typically, and a lot run less (though mechanics in the field would do what they could to increase the rev limit).  Most run into a hard rev limit when the valves start bouncing, and that's often less than 4,000 rpm.  You want usable torque from a tank engine, rather than sheer top end power.

No. Just..No. "Moarr Powahh!" rarely ends well when dealing with tracked vehicle drivelines.

You're not dealing with the relatively simple drivelines found in a car, when you start increasing the grunt fed to a tracked vehicle's transaxle without that transaxle being stressed for it , all you'll get are loud noises and immobility.
