- This video contains dyno runs from top 5 most powerful cars of the event. Some records for 2.5tdis and pretty weak results for dssr nozzles.

Hey I´m planning a 5cyl TDI project and would like to know who did the software on these cars?
I´m looking for a diesel expert who can build the pump and tune the software/perfect nozzle size.
Can you guys help me?
@bigdiffas maybe?
Was it an 11 or 12 mm Pumphead in the last red Golf III?
+RoboKOPPS 11mm
nice dyno runs, did you set the same pop pressures on hflox .341 and dss-r. 360 ? so not then results ar different and cannot be comparable
+Bernard van der veen Bigger nozzle needs higher opening pressure for better atomization on lower pump pressure lower revs and there is actually not that much difference in flow in full load when the pump pressure is very high. Bit increased opening pressure on nozzles leads to injection to happen always at a high pressure and hence atomization is better and mixing with air is better. Higher injection pressures also gets you bit better thermal efficiency because better in spray and combustion quality. Sure with too high opening pressures injection gets delayed, that is some what compensated by the pump. I believe hiflox had tad low opening pressure here 250 vs. 270 on dssr. I'd personally like to see close to 300bar pressures on that big nozzles.
Hi yes buth when you increase 1 stage pressure then your second one is way high. 260/340 bar.
Does second stage automatically raise with it.
What about 1 stage injectors set at 300 bar.
I got lot fuel over now with 12mm de143 dss-r.360
I'm about 3700 in pump voltage map without factor around 4.5 v in vcds.
So dss-r at 270 bar and hflox at 250 then the hflox nozzles inject longer than dss-r nozzle at 270 bar
Isn't it the time the injector stays open when the camplate starts to build pressure ,250 bar is reached sooner than 270 so 250 injector inject earlier . ore I'm look worng to it.
Needle lift sensor indicates when nozzle opens, so even with higher opening pressure it opens the same time.
Why 11mm ( only because rev high ). Do you know why bigger nozzles show less power? Is it because bad atomization or problem with timing on new nozzles?
Hard to say. probably quality of the nozzles. 11mm seems to be only pumphead that supports revvs and fuel when going over 350hp. We had 470hp with 12mm but pump didn't like it and few pumps were destroyed. Thats a shame because some serious power would be availabale with that

I want to hit near 400hp with stock afn engine. only combustion chamber non serial. Can you say how much boost i need to use to hold 400Nm at 5500-6000. And is stock rods hold it there? Turbo gtb35 pump 12mm de143. cam 038E.
You need closer to 550-600nm to hit 400hp, even when revving up high. Probably around 3.5bar boost should be enough. You should change rods and probably also gridle is needed.
