Hello, found a thread on here that piqued my interest but I have to have a couple of posts prior to PM'ing the guy who can answer one question for me. So, in order to get there I'll post a couple of Hi, how you doin' posts. Sorry. I'll try to make them not meaningless.

I have:

2002 Dodge 5.9 litre 5 spd 235HP 4x4 crew LWB. I have replaced the factory LP with a Holley Blue pump and added these gauges: boost, fuel pressure to the injector pump, EGT, oil temp, trans temp, and rear diff temp. I've added a Flowmaster 4 inch turbo-back exhaust and a BHAF. I added a Banks Big Hoss module with boost elbow which was a waste of money. After the Banks Big Loss (of money) the turbo seemed to spool up faster but that was it. I've been considering a p-pump (mechanical pump) but I can spell it but don't know much beyond that.

I'm sick of playing chess on the hiway: ohh, I want to pass this vehicle...okay, well, how far is it to the next vehicle oncoming, how long is the passing zone, how long will it take this POS to spin up to passing speed, and how far back to trail the vehicle I want to pass and when to nail the pedal to get up to speed at the right time to jump out and maybe get around them.

My gameplan now is this: start small and go big as needed.

The air filter and exhaust have been met.

I plan to remove the Banks Big Loss since it doesn't do boost fooling and doesn't seem to do much, if anything, with the fueling of the vehicle.

Next I am looking at changing the intake horn, maybe doing the intake heater delete.

From there, since I feel burned on the aftermarket add-on modules thanks to the Banks Big Loss, I would like to make a homemade boost fooler. Next up will be looking into replacing the turbo. I've read somewhere that I can simply bolt on a 03 or 04 turbo in place of my HX, as I recall it is, turbo, which is reportedly larger and flows better.

Next up will be a slightly larger set of injectors.

Oh, and this chess match on the highway of passing vehicles on a two-lane road happens even empty with no trailer and is made much worse when I tow anything, empty or not. I'm not too happy with my truck's performance. I've owned it long enough and it's not my daily driver anymore, just a work truck...I want some oomph.

Besides the Banks module, no other fuel adding electronics?

What is you fuel pressure at idle, cruising, and under wide open throttle (WOT)?

Sounds like you need to be introduced to a chip that works well on these trucks. Banks has their place, it's just not on a 24 valve, VP-44 Cummins. Try finding an Edge Comp box. You have enough gauges to monitor the important stuff, except exhaust temperature. You'll notice a HUGE difference in power, plus the Comp does boost fooling.

 

Hey, RAW, thanks for the reply. Yes, you are correct, no other fuel-modifying add-ons of any type electronic or otherwise.

Fuel pressure at the banjo bolt on the HP pump is (all in PSI): 12-15 at idle, around 10 at cruise, and will get down to 7 at WOT. It jumps around a bit, it's not perfectly calm. When I start tinkering on this thing I will either add another Blue pump in parallel with the first one or look for a higher volume pump than the Blue pump.

I feel kind of burned, as I mentioned, with the electronics add-ons (namely that Banks POS). As part of a quote from one diesel performance place, interestingly enough, I got a quote for an Edge Comp, somewhere in the 500 range, as I recall, same as I paid, close enough, for the Banks.

I'm not trying to be the jerk who can't take a suggestion but I like to cover things thoroughly. If I do the air delivery mods such as the air horn and heater delete, replace the turbo with a larger one from an 03-04 (if that is truly possible and easy to do), and then rig up a boost fooler (I have some ideas for some electronics to do this 'cause I'm cheap and 'cause I can ), and basically piece-meal this thing, would I not be better off in the long run?

What I'm thinking is to use some "dumb" technology to improve the performance; stuff that doesn't break and also can be applied to future setups. Better air flow in works whether I have the VP44 a year from now or a p-pump, same for the bigger turbo, and larger injectors, right? At least I think so. I could be wrong, I've got a lot of experience with that.

Thanks for your reply and time.

Transfer pressure looks good for now, wouldn't want to go any lower though. A good fueling box, like the Comp, will change you WOT pressure drastically. Might even drop it close to 0 psi. Depending on the cost of another Holley, and all the plumbing to make it work, you may be better off cost wise to go to a Raptor100 and be done with it. Not as hands on, but tried and true technology that is used A LOT.

I can understand you feel burned, I would to. Research, as you are doing now, will help prevent this in the future. Mid $500's is a good deal for a Comp. You may be able to find a used one for $400, but no less.

Piecing it together works sometimes, but not all the time. In regards to a boost fooler, I would just buy one IF you aren't going to get a better chip that has it built in. I pieced together my compound turbo set up, saving over $1000. A little different that a little computer confusing box, but perhaps an example of where to save, and where to just buy a tried and true product.

There are mods that you can do now that will work with either injection pump. Exhaust, turbo, intake horn, air in and out won't change. Injectors can be used with both pumps, just need to have to pop pressure adjusted when going to the P-Pump.

If you have more questions, just ask. We are all here to help one another out.
