Got the timing pretty good now. It's either the 3500 psi pop injectors,or the .040 shaved pistons plus .010 over gaskets,thats delaying idle ignition timing. The pump internal advance is all the way maxed at idle,and the ip is advanced alittle past the line. So it has a ton of injection advance...

Yes it is behind the bumper. The bumper is from a semi,so we had lots of room.

Well it makes 28 to 30 psi boost. The timing needs some fiddling with . The lowered compression,combined with a big intercooler makes the idle timing a bit complicated. I'm going to have to bump up the idle speed . Also the clutch slips , ceramic,but stock pressure plate.

You need to do this again,or pop test the injectors. Also double check the return line ,maybe put a hose from the ip directly into a container.

Well we drove it a few miles. Makes 20 psi boost ,prob will do a bit more, but kept blowing off intercooler boots. Has a bit to much timing at part throttle , and hazes a tiny bit at idle. It has a nice exhaust sound also.

I had the ip advanced 1/4 inch past the line,now with more charge psi ,the internal advance moves farther. This eliminates the need to have the ip past the line.

Swapped the charge pump regulator with a previously modded one. I also upgraded the spring. Now It has 85 psi at idle ,and max psi of 125. This advanced the timing enough to enamble the ip to be at the line.

Well I got 40 psi at idle and 80 psi at higher rpms. This is where a 30 psi lift pump would be perfect, instead its more like 5 psi.

Not enough timing at idle,so would like to see 75 psi mininum.

Have to take the turbo and intake off,so I can install a charge psi gauge and crank it up slightly.

The nozzle wasn't seized,just not seating correctly,most likely a piece of dirt.

Yea, the nozzle was leaking compression into the fuel. I heard it can happen, just never seen it.

I built the pump ,it has a new head and rotor. Injector lines aren't loose. Injectors have china 311 nozzles .

I have it fixed allready,just testing you guys a bit.

Finally started this motor in the truck. It ran fine for a bit ,then dropped a cyl. When cracking the lines,barely any fuel at #2 cyl. The little fuel that came out was foamy. Can anyone guess what caused this ?

They are the same,just different head and rotor,and slightly longer inlet cone.

You will need a standalone trans controller. Or somehow convert the 7.4 to 58x tone ring and use the 2011 ecm and tcm.

It's a 99 k3500. We are pulling the cab, so we might do a small body lift. Or slide the cab back,like one inch? It's also getting a custom flat bed ,which could be mounted slightly rearwards also.
