Basically, your 1100's -- assuming the 1100cc rating is accurate -- can only flow at a very theoretical max of 1283cc with the stated pressure increase. 3 bar to 4 bar is a 33.3% (1/3) increase in pressure, which means a 1/6th (16.6%) increase to flow rate, or 1100 * (1 + 1/6) = 1283.33. All injectors are subject to the same principles of fluid dynamics
Because I love math -- note that the ID1000 and ID2000 flow goes up by ~16.26% and ~15.73%, respectively, when pressure is increased from 3 bar to 4 bar. The theoretical increase should be 16.6%. Not a coincidence
I do stand corrected on Bernoulli's principle.. Thanks for the reminder!I do not refute this. I guess based on the manufacturer provided charts based on fuel pressure changes that the DW 1100's may be underrated as to their size. I will post up the pressure corrected chart from these injectors to compare. I'm just do not have that info at hand right now.
