After driving around today some more, a haze at absolute most is what I'd call it. After the light tip in puff, I couldn't see anything behind except once when a car with headlights on was behind me. Even then, was just enough to see. She definitely wants more fuel . I contacted the gentlemen who supplied the nozzles about enlarging them .

Yes I agree about the larger nozzles...I'll wear eggs on my face if it doesn't make a difference This project has been innovative as is; let's take it up a notch.

Supposedly there is a vendor or board member "KTA" that produced a 14mm head/cam that was of high quality and lasted for the Cummins guys. I'll look into it and see if he still produces, does the cam plate match ours? For all the failures I'm assuming it was because of the cheap Chinese cast?

From what I've seen, the 4BT cam plate has the same foot print, but the profile is different. I would stick with the VW cam plate.

If you look at most injection pumps there are a bunch of numbers on the side. One of them is the governor speed and since the pump turns at half crank speed, that speed will be half of engine RPM. Typically the 4BT pumps show a governor speed of about 1500 RPM, or 3000 engine RPM. So, as you can imagine it is a little out of the norm to spin them to nearly twice the intended speed. I think that is a major contributor to the pump failures, but obviously if the quality isn't up to par then the failure rate will be higher. So, that said, get the best quality of parts you can and keep an eye on fuel lubricity. Some people like to add a quart of two stroke oil when they fill up which I've never tried, but I would think it would make the pump happier.

Still researching late night right now and there are mixed reviews with the 1st gen dodge crowd 12mm(high rpm) vs. 14mm(low rpm). Doing some rough calculations with different ratios to compare nozzle sizes of what they are using; I'm coming up with an optimal .0144 for us.

Obviously there is a plateau with the single piston pump hence all the P-Pump conversions(not an option for us). We'll find the sweet spot within our scope of capabilities gentlemen; be patient more to come.

If anyone with more knowledge than me can provide a cc's of fuel vs. RPM's chart that would help us compare and come up with better numbers of how much fuel is needed.

Still 100Nm less as what a 12mm can do... do you know the QA voltage? then we could rougly comapre the duration needed for that fuel

car has been changed to stock to sell it by the way...

yesterday I heard that the head, pump and turbo have been fitted to an engine on a tractor for tractor pulling..
should be doing well over 300hp now...

The Aligator 11mm+ pump idea was the ticket back in these days.
From my experience (and Aligator's) regardless of the numerous cam plate/spring combos tried, the best resulting 12mm/14mm pump delivered more fuel down low than the 11mm, and much less fuel past 3000rpm than a properly modded 11mm.
And to think this was all before we had awesome, large, custom nozzles available!

Post #8 in the below thread. Should get ahold of old Ali & find out which cam plate that was to make his 11mm+

Center Driveshaft fits like a glove .



Now its time to make the exhaust fit. This is going to be interesting....

I have no doubts that you can make it fit

Maybe split the exhaust into dual pipes to keep flow and fit smaller pipes under there? Maybe dual 2.25" or 2.5"....
