Ok guys i am trying to understand this thing (bhp per injector)

we have 1.5 bar of boost
we have 4.0 bar fuel press on idle

4.0 bar on greens = 493 cc/min

so on WOT (Wide Open Throttle) you have(need) 4.0 + 1.5 = 5.5 bar fuel press


5.5 bar of fuel press on greens = 390 cc/min (2.5 bar) + 427 cc/min(3.0 bar) (given by matts figures)

= 817 cc/min

now convert cc/min to lbs/hr

817 / 10.5 = 77.80 lbs/hr

now i want to calculate the bhp per injector

inj. size (lbs/hr) * 0.8 (80% ducty cycle) / 0.6 (.60 lbs (turbo charged)) = bhp per injector

77.80 * .8 / .6 = 103.73 per injector

all 4 injectors 103.73 * 4 = 414.92 bhp

now is this correct? (i think not but where did i fooked up?)

and is there a way how you can calculate which plug gap u need?


thanks!
