Dual CP3's anyone???

[JCleary]

I was just looking at my truck and thinking about twins. Then TDR threads started popping into my head.



It seems the concensus is that the CP3 will support just under 700 hp before it runs out of fuel.



In my simple mind, since the truck has a common rail, couldn't you supplement the fuel rail with extra fuel from a second injector pump plumbed into the same rail?



I would think it would be relatively simple to control both pumps with the same signals, right?



I guess the difficult thing would be driving the second pump, unless someone could utilize an accessory drive like you would for a blower.



I don't know too much about these motors, so I thought I'd just toss it out there. Any ideas?

BUT will the rail hold the pressure of TWO cp3??

 

[RedRam401]

Why would a second CP3 add pressure?

Is the pressure controlled by volume?

I thought that the pressure was constant with the excess fuel returned to the tank. If that is correct a second CP3 would allow more volume at constant pressure, of course rail and injector size increases would probably help also. The stock rail will probably not flow enough volume without exceeding safe pressure limits in the rail.

Six CP3s will only flow as much as the rail will allow at any given pressure.

Keeping the dual CP3s supplied with enough volume would require some rework also.

aftermarket rail = problem solved

Is anyone making one yet? Seems to me there'd be a big market and potentially significant improvements to be had.

I was thinking about the second pump making up for the volume of fuel demanded by the injectors, not to increase pressure. Overall pressure would stay the same, but you have twice as much fuel available.

Banks had a different rail on their Sidewinder project truck.



Here's a better idea, how about a CP and rail off the 8. 3L motor???

I have a pic of the Rail ,I will post it .

Banks sidewinder Rail

 

[CumminsBu]

Can't wait to see what Banks is doing with that engine! Oo. Oo. Oo.

 

[TheWolf]

banks is coming out with a vgt turbo also. . it was in TRUCKS a few weekends ago, said it was the prototype.

 

[Diesel Nut]

Well, anything with the banks name is liable to cost at least 2-3 times what the product is worth. And with single turbos from more reasonable manufacturers for the CR motor in upwards of 2 G's, it'll probobly be the same price as those twins I want! And then some!

That rail is different than the ones on our trucks but it is not a Banks Sidewinder Rail. That is not the 5. 9 litter Cummins engine that is used on our trucks it is a Cummins ISB with tier 3 emisions. That is the engine that they took with them to shows and took pictures of for displays. It is a stock Cummins Rail. The line that comes from the CP3 is fed into the top of that rail (the one with the missing fitting) insead of the bottom for our applications.
