Ute, I look forward to your findings as you are running the same injector as me I believe.
Are you running two pumps also?

Just a single 044 in a surge tank. The 60lbers are a bit big as N/A I am still under 400rwhp, but a bigger dry hit of nitrous is coming.Originally Posted by 1bar

I'm still playing with this, I don't have enough data yet...
Something else to consider...
the scope waveform shows dips in the current (opening) and voltage (closing) waveforms...
the width of the dip represents the pintle moving from fully closed to fully open (or vice-versa)... during the this motion there is ramping flow which is proportional to the cross-sectional area of the open/closing "orifice"... i.e. the flow ramps up as the injector opens and then ramps down as it closes... from the waveform you can see that the dips have finite width... maybe about 0.2-0.4 ms.
I am sure on a proper bench the amount of fuel injected during the ramping could be measured accurately. Just comparing fuel injected from 3 different pulse widths would give you this amount. Then small pulse adjust etc will be able to be back calculated (I think) from this info. Any thoughts?
Yes, that sounds right... and with a proper injector bench you can measure the amount that flowed into the measuring vial.
A mate up here with the proper flow gear has left, but he did onsell it. I will have to drop around to the new owner with a carton & see what he can do, or what his capabilities are.
Sorry about the hijack 1bar, I will start a thread on this as the info comes to light.
Cheers Mick
