total newb to diesels got some ? 's

Alright so I just purchased a 7.3 but I look at the motor and am completely lost. Im looking at exhaust and I see up pipe down pipe and Turbo back and I look at everything hooking up to the Turbo and doesn't make sense to me. Are there even headers? Sorry if I sound like a retard but I have zero experience with diesel

So what is your question

[DrewGerhan]

Our motors have exhaust manifolds on each cylinder that go to the up pipes (on each cylinder head). These go into the turbo. Once the exhaust gas leaves the Turbo it goes into the downpipe and back through the rest of the exhaustsystem until it is out of the tail pipe.

OK gotcha. So the explains the up pipe. Now what's the down pipe. And my overall question I guess is how the whole system works from intake to Turbo to intercooler to up and down pipes.

Air gets pulled into the turbo through the air cleaner, pressurized, pushed into the intercooler (which technically, is an aftercooler), where it's cooled down some, from there it's pushed into intake manifolds. After entering the cylinders and being compressed, it's mixed with diesel fuel, ignites and is pushed back out the cylinder, through the manifolds, up the up-pipes, into the turbocharger, spinning the turbine and compressor wheels, then it exits through the downpipe (pipe leading off the turbocharger outlet on the exhaust side), and out the exhaust system...

That's the quick and dirty version...It's actually more detailed then that, if I was to get into engine rotation, valves and the utterly complex fuel systems these trucks use...

Air is sucked in threw intake via turbo then compressed from turbo to intercooler then y's off to intake manifolds, combustion takes place, exhaust is produced sent out the manifolds to the up pipes which y's into the turbo, exhaust spins the turbine wheel (which is connected to the compressor wheel to create boost) and out the single down pipe... That bout sums it up

Oops I was a little slow on that

Awesome thanks guys makes sense now
