After a few timed runs on the 0.6mm nozzle, the results are not very encouraging.
The difference of water injection in total is minimal 1~2%, barely measureable in fact. You only get on-the-wheels figures with the accelerometer, but using the same stretch of road same day etc gives very repeatable results (not nice curves as the dyno though!)
I thought that maybe the higher boost pressures would be happy with the bigger nozzle, but apparently I went too far.
It didn't even *feel* different either (the 0.4mm nozzle felt different back to back)
Good thing perhaps, because it used around 400cc during 5 runs of 40-100, quite a lot actually...
Fitting the 0.5mm next time, and see how that goes...
(I've measured again the flow of the 0.5mm nozzle, it is 240cc/min with the engine on idle, it would be a bit more with a strong vacuum inside the pipe, wouldn't it?)
