Ok I don't know alot about diesel motors, I do know how they work but just dont know alot about what you can and cant do to them. Besides that I had an idea pop up today in my head while workin on my 1st gen dodge. Can you inject air into the intake manifold? Like from an air tank being filled by an air compressor with a valve to contol the psi going into the intake from a throttle sensor or something? Not completely taking out the turbo, still using the turbo but adding more air from compressed air kinda like instead of injecting water/methonal just inject air???? Just a thaught let me know what ya think or if im just a complete idiot

 

I think you'd have a hard time producing the kind of volume needed to make a difference if the plan is to increase boost.

 

well you could use it for an instead boost like runnin in an 1/8 mile or 1/4 drag. not a constant boost cuz you would need A BIG air compressor to produce that but i dont see how it wouldn't work?

I think it would work awsome if you also injected water/meth too

 

The stock motor can handle increased boost and you can't lean burn a diesel. Attempting the project probably wouldn't damage the engine so long as you keep the drill shavings out of the intake. I'd think you'll want a large port installed between the turbo and the manifold. At least an inch in diameter.

 

Yeah i have 3 first gen dodges and i think i might try it on the oldest raggged out one thats a future project truck to busy with the other 2 right now so im deff gonna try it it wouldnt hurt! who knows i could be rich!!!

 

That could be used as a preturbo boost to illiminate some turbo lag its an interesting idea and could be worth experimenting with. I like the concept just don't know if it would work enough to notice or not

 

I've tossed around the same idea, I feel you'd have better luck shooting the air into the exhaust manifold to spool the turbo instead of into the intake

Yeah that's a good idea too never thaught of that but yeah you could just use it just as a pre boost until your turbo spoils up so that would mean more power off the line or like towing up a hill it would give you more power there too

 

You would never notice a difference. No Where near enough volume. As soon as you oleander the valve the tank would equalize to the manifold pressure. Then anytime you spooled up any more boost you would have all the extra volume of the tank to fill. Remember pressure is nothing more then a measure of resistance. Volume is a measure of how much air you are moving. Your engine under full boost at high rpm moves alot of cfm's. Way more then any air hose and compressor could ever wish to.

 

Kind of why I suggested pushing it into the exhaust manifold, but it'd be one of those feel good things. Good in theory but prob not worth anything in reality as far as efficiently working. See I was thinking two one inch inlets, one into each volute of the manifold. You'd be able to flow some air then, only problem is you'd be good for only one hit and finding a compressor that's keep up and still have space is impossible. I work on skid mounted industrial air compressors. They're rated at 1170 CFM and 375 psi. 2" discharge, pressure will drop to 185 with valve wide open and engine at full load. 1170 CFM is plenty but they're powered by a C15 and are the size of a truck. look at your everyday shop air compressor, the expensive ones only flow 23 CFM at 90 psi ( or in that area) practicality just isn't there.
