no 225hp box for 3rd gen

[CATCRACKER]

talked to mark at quad to see if they were planning in a 225 box like they have for the Duramax he said no b/c the 2003 CTD runs out of fuel. that stinks. looks like we are still have to install an addtional lift pump,larger fuel lines, and fuel pressure gauge etc.



I know this fact has already been determined that our fuel needs were inadequate for over 400 ponies.



I guess i will be getting the edge comp box if it ever comes out.

D/C probably designed it that way to curb tampering = illegal emissions

But what did Cummins design the engine to really do? Like in marine applications? Anyone know?

the one banks ordered came with either 370 or 390 cant remember

Hey CC. I thought you were dumping that piece of junk? Now you gonna put a box in it? I just knew you were a true Dodge guy. Finally saw the light huh?

I was able to pull my fuel pressure down to zero with just the ez. Not the only one either. One fellow stalled his on the freeway when making a run. That was ez only. So much for the common rail doesnt really need a pusher as some were saying. This has been known for some time though, some just didnt want to admit it for whatever reason. I used the Diesel Dynamics pusher pump kit which works fine and will allow you to run those injectors you know you want (c'mon, you know you want em) and should allow you to stack as well. The kit is well thought out and installation is simple. The pump mounts back by the tank and you deep six the banjo's and replace them with an fittings. The noise from that carter is really noticable on a common rail, thats about the only downside IMO.

I agree about the noise from the Carter pump, it's kind of annoying. It almost sounds sick at times and i notice a lot of vibration in the hose coming out. I've noticed no misfiring whatsoever with DDIIs and the DDTTPM so I guess it's doing it's job.

If your fuel tank was sitting on top of the engine you would not need a delivery pump and your pressure would only be about 1 psi from the head pressure - and you would get plenty of fuel flow (this is how many tractors are set up). So maybe the problem isn't in delivery pump pressure. Could it be that the fuel tank is not pulling in air as fast as needed to allow the fuel to exit? Has anyone tried doing these runs with the cap off? Maybe we need a hole in the cap to allow more air in?

You need very little pressure if you have a large enough fuel line. If your fuel line is too small then it takes a lot of pressure to get the same amount of fuel.

Wasn't this an issue on the early 24V like 98. 5 and some 99s? I recall a TSB for low power that was caused by the tank not venting properly.
