I've kicked around the idea with a few different people.

It all started one day when i went to an injection shop down the street from where i recently moved. They had a HUGE procharger sitting in the glass and i asked how much thats worth. They wouldn't tell me because "if i had to ask....". Then he told me that nothing i had would have enough horsepower to turn it, let alone make any power with it.

I then proceeded to tell him i had a diesel truck and the reason i came was to ask about his dyno. He mentioned something about another guy who worked there who tried to put it on his duramax but it wouldn't fit in the engine bay. I told him that wouldn't be a problem with my truck... but that fell on deaf ears.

Anyways i'm interested in this for a few reasons...
Because of the gobbs of low end torque the cummins makes
The chargers make full boost at only a few hundred rpms
There is plenty of room for something like this to feed a second or third turbo.

Another reason these may be a good idea for our trucks, is because of the amounts of air they flow.(5400 cfm this C4 by procharger 900hp required to drive it"")

I'm looking for a picture so you can wrap your head around the idea of how huge this thing is...




Let me know what you guys think... or if there is already something out there.

I know the big trucks run twin superchargers to 2 or more turbo chargers...y can't our little engines do the same?

 

after a little more reading aside from the fuel economy part of it, there doesn't seem to be a huge down side, just so long you don't have a supercharger that is too small. Also be creative with the gear/belt ratio because of the low revs of the diesel.

 

Are all 6 cylinders going to sit next to u under you're girlfriend when you install this? hahaha there is a severe lack of room for that thing, but one thing a turbo has over a super charger. energy. it doesnt take power to make power with a turbo. a super charger used engine hp to drive the components. but with a supercharger there is virtually no Lag. but if you ran a procharger like alot of guys do on V8's (smaller than in your pic) it might work.

 

Mount it out in front of the bumper then run the drive shaft for it through the radiator like a live pto pump on a big truck. That would be cool lol.

 

I was thinking mounting it where the a/c compressor is located, but that has me thinking put the alternator where the A/C is located and free up some room to the immediate right of the motor.

I just picked that c4 one for its sheer size.
I was thinking something mapped for a 454 might work for our size motor.
That should help fuel pedal response until the turbo lights.

 

that would be sweet, with a fire-truck style front bumper and some bells ans whistles too because at that point y not!

 

ive seen duramaxs run prochargers befor. i think the rpms arnt thier to create max boost. the only thing i could see working is to plum the charger right into a massive turbo.

 

what he said

 

y not change the drive ratio, that would pick up the lack of rpms, because they plateau at a certain rpm anyways.

 

As a long time Procharger ( 1997, I got the first D1 ) owner, I can tell you that you are heading for unimaginable pain.

Looks cool, will fall far short in execution. First is the drive issue. Procharger has been very optimistic let us say in their drive calculations. Yes, you can get them to stay alive, just make sure you go big on the belt.
Next, good luck with any transitional RPM work, true, I get 18 lbs of boost immediately, but it is all there, right now.

Do what you wish, but I guarantee you that a set of twins are far preferable to that thing..........

 

I am doing research on the subject, and my plan is to plum the pro charger directly into a massive turbo. Im not sure what im getting in to but as far as my understanding goes, I should not need a big procharger to get a quick spool, and as far as that goes why couldent i plum the pro charger in with the exuast in a y pipe so i get the low end from a small pro charger that would not take to much power to run and the exuast flow would take over higher up in the RPMS. this is just my theroy but not to meny people have been pro charging cummins so its hard to get information

 

Wow that looks like my 6" trash pump.
So what are the advantages of this over a Roots blower other than being centrifugal?
Do they run off the crank?

Yip belt driven. To me bascially a belt driven turbo. IMO has the disadvantages of both superchargers and turbos. The lag of a turbo, and teh parasitic drag of a supercharger. I would perfer a whipple or roots style. However this is in reference on a gas engine. Not sure how it would fair on a diesel. Definatley interested.

 

I think plumbing your pro charger into the exhaust is going to bring up new problems because exhaust pressure usually exceeds the intake pressure and you would be blowing cold air into a device that's made tone driven by hot air....just a few things to think about.

Usually you see a pro charger on a cheap build or something where plumbing a turbo would be difficult or there isn't enough room under hood for a conventional supercharger.

If you plumb it into the big turbo ull be building boost and throwing more fuel into the mixture pretty much right off idle which should help spool the monster....that did come off something 3 or 4 engine classes bigger than the little 5.9l

 

Already proven Cummins setup is a big turbo blowing into a Roots type (2.5L Whipple and a M110 Eaton) charger with an internal bypass.
