Well I got the chance to do some more tests.
I am happy with the results as they much more stable and can be reproduced time and time again. I have altered hydraulics set up by relocating pressure gauge from pump to nozzle.
Top graph is a relation of voltage VS flow on setup as per Richard request.
Bottom graph is the same setup but with added accumulator in the system.
The numbers speak for themselves.
Richard I have tested 0.3 Aquamist nozzle, it flow 112cc @ 162PSI (pump with accumulator) It looks like thad by the end of the tests I will be ordering another 1-2 (0.3) nozzles from you with ?mounting sits?. As my hydraulics and motor dynamics get put together few adjustments are obvious.
By the way this is how intake track looks on my car:
The runners are over 300 mm long and I plan to fit one nozzle per runner just in the beginning of it. This way water will get to travel a bit before it hits valves.
Unfortunately AUDI engineers have designed the intake in such a way that the flow is violent with 120 degree turns ( towards cylinder1-2) which makes one nozzle injection useless. So the installation of ?cooling? nozzle before the throttle body is questionable as all not evaporated (and large) droplets will end up in third cylinder.
Comments anyone?
