Turbocharged 8.3L Air Compressor

[74M35A2]

No wonder why the brakes are so strong on my 925a2.

The engine mounted air compressor draws fresh filtered air from the engine intake manifold. When the turbo is awake, this intake is under positive boost pressure. So, under boost, the boost is also pushed into the air compressor inlet, therefore supercharging it.

And now we know why 8.3's are better, because they have turbo-supercharged air compressors.

-THE END-

Yeah, little wonder your compressor has so much supercharged pressure, your puny 8.3 has to run at 25 psi boost just to keep the truck rolling at 10 mph unlike the 400, a real otr engine. (Lol)

"Swing and a miss". Next in line please. LOVE IT !!!

Clint, you've lost your internet privileges for today.

Because of that there should be a turbo cut out on the governor, that will shut the air compressor down under high boost.

 

[74M35A2]

No way. It just shifts into overdrive and looks for 250's to eat....

 

[Jbulach]

This just gave me an excellent idea Watch out, leaf blower forced induction dudes! I’m going to need a bigger air tank...

Just remember how some 8.3's get home, right behind a 250, riding as smooth as a Cadillac. With no broken torque rod inserts and their air compressors quit working.

 

[Jericho]

Lmao !

 

[Buffalobwana]

So, the 250’s have no compressor parts to break? Who knew!

 

[Buffalobwana]

Clint, why are you picking fights with the internet again. You aren’t even keeping this engine!

The next one has even more air compressor boost. 39psi. Almost don’t even need the compressor.

Had you read the -10 (basic operators manual), you would have known this.

It's explained in the second chapter of the ninth paragraph, shown in figure E-3.14.

I just don't understand why you guys never read the TMs...

Meh...this means when your compressor is running, you're loosing engine boost. It's like having a factory built turbo leak, haha. Guess that's why the 8.3L is rated and 240hp and the NHC250 is rated at 250hp.

It might explain the busted rear window though. Extra pressure in the air system...leaking dash valve...windows rolled up...BOOM! That extra pressure has got to go somewhere, lol.
