Slowly clearing the stack of truck parts and finally getting it on my truck.
Had a few days off and was itching to get the new injection parts on my truck.
I decided to splurge earlier on in the year for an upgraded 12mm XXi Industries injection pump and matched injectors.
It would have felt stupid to just do injectors when my current pump has ~172,000kms on it. The truck ran good but the injectors needed to be done. I decided to kill two birds with one stone as I would feel like an idiot to have to go through the pump in 50,000kms and have to get injectors matched at the same time, essentially doing injectors twice. Overall wasn't too hard of a job to do.
Intake manifold gaskets needed to be done, allowed for better access to the pump.
VE Pump Puller
Stock 10mm 1HZ pump with Boost Comp vs XXi 12mm 1HZ pump
Installed
Driving impressions so far is that the truck pulls SMOOTH and hard when it gets into boost. I have relatively untouched the pump in terms of tuning at this point (on my end) the fuel pin was set up good to begin with. It set very conservative at the moment (which is good). I will be looking at fine tuning it a little bit with a slightly modified profile and a cummins AFC spring. The truck has been running 20lbs of boost since the intercooler has been installed. EGTs are slightly cooler with this pump when driving around under load (hill pulls) and not any higher than the stock 10mm pump. Overall though there is definately more power from this pump and its noticeable. Slightly less responsive than before down low but there are multiple factors on why this could be. It really comes alive 2000rpm and pulls hard to 3000rpm (haven't taken it higher but if feels like it will keep going). Exhaust is very clean. I will be ordering an Innovate AFR gauge later on to tune a safe 22:1 AFR and get a really safe and reliable tune. Mark (TheBigBoy) has got over 200 rwhp out of the exact same pump running 22-23lbs of boost at 20:1 AFR (XXi Airbox, XXi Intercooler/plenum and Gturbo Badboy). It was previously tuned for 186 rwhp with no intake manifold with 22:1.
I'll report back about fuel economy, I need to get a few tanks in for some mixed driving results and ski hill runs. No long distance highway planned as of yet.
I tried putting a Racor r445 filter housing with a built in pump and a r45s (2 micron) diesel filter on in the spot of the factory fuel filter. Could not get the filter to prime for the life of me, even with the filter filled. Found out it was a faulty Racor. I am undecided at this point if I am still going to try and pursue the Racor route or just stick with the factory filter. I wanted a visual bowl and better filtration. Canada generally has very clean fuel and even my old fuel filters look very clean. My cold starts have improved with the new pump and injectors (i suspect it was the injectors that made the difference).
I need a Trunk Monkey switch.
