Well I've made it home for the summer and it's time to start tearing this thing apart. I will begin tomorrow, but yesterday I took it to the dyno. Laid down 503 / 1215. I was very pleased with the numbers, but the knocking is getting worse to it's time to take it apart.

@jlbayes do you know if there is any identifying marks on the PSG's?  Such as if anyone could tell there was a SO pump with a HO PSG on it?

Only if they are reading this thread. ...

So in case anyone was curious what this "Cold Rod" pump sounds like....  Here it is at idle.  As soon as the engine is loaded, even with just the A/C, it starts to behave normally.

Effective what is happening is the ecm is asking for a lower and lower fueling command until it "bottoms" out then it is cutting fuel in a last ditch effort to get rpms down.

 

Since the HO psg is calibrated to convert the fueling message according to smaller plungers it needs more fuel to idle.

So that would mean the HO fuel message would be maxed out sooner.... Hmmmm

I'll send ya a data log in a bit 

I wonder if that has something to do with the excessive smoke when the truck is lugged too

Internet said otherwise.... Haven't seen one done yet. 

That's what I don't get... You can change this thing out very easily, so why don't they sell a replacement? Calibration can't make that much of a difference, especially on a stock truck. The ECM will compensate for everything but timing, which a degree you would never notice a difference.

 

It is exactly what they do with the hrvps on the test stands. Write up on compd showing what happens.

Alright I'm a bit confused.... The SO PSG is decoding the message and giving more fuel than the HO PSG was. 

So the HO pump must move more fuel at idle than a SO pump right? AKA the SO PSG is telling the pump to use more fuel with the same message?? @Me78569 sound right?

 

that's what I am thinking. 

So that's why the HO pump idled around 11.22*?

I think that was because of RPMs. 

 

I ordered Larry B's wiring harness kit for the shutdown solenoid. Hopefully that'll be here soon.

You happen to know where to get clamps for a VP44? Pretty sure a couple of mine fell off

You said where they will fit, but where would that be?? It looks like they put them in all the good spots. Only place I can see is the 5/6 lines closer to the pump.

@trreed might have some depending on what you need. 

Any idea where to get some clamps for my lines @jlbayes?

 

Got some work done tonight. I picked up a new T clamp from Central State Hose in Denver. I cut some 1/2in dowels to length, and split them at the ends. I will round the ends with the bench grinder when I get home. Most of the Crazy Carl kit should be at my parents place tomorrow. It'll be missing the throttle kit and the tunnel ram. They won't have tunnel rams until late next week, so I bought a grid heater delete to use as a spacer. I also bought a chunk of 3" exhaust pipe to use between the horn and the IC. I got 2 feet, so I'll cut it to length and weld some fat beads on it to keep the boots on under higher boost. @trreed what's the bolt sze and thread pith for the intake plenum? Hopefully the APPS kit will show up next week. If not, I'll build my own linkages for the time being. Diesel Auto Power can't seem to pick up the phone and call me back about my injectors. I can't even remember how long they've had them at this point, but I'm getting a bit pissy about it  

 

Old T bold clamp. RIP

 

 

@notlimah I found some clamps on some mopar overstock site online. 

@TFaoro Intake plenum bolts are M8x1.25x25mm

Link plz!

I got the part # for the clamps and googled it. Many mopar over stock places have them the little blocks are pretty reasonable but the like actual clamps and shipping. Made them a little pricey. But I need some too and will have to order soon.

@notlimah here's where I got the clamps I needed: http://www.factorychryslerparts.com/showAssembly.aspx?ukey_assembly=659993

Thanks!

Looks like everything is on sale now. I remember having to buy #22 at $65...

I used my old vp line clamps. As far as a source....I ask around for used pending they do not think they are worth gold.
