0.3 jets, are they now available then? I thought 0.4 is the smallest (what I was using)
Also in my experience the 0.4 flows more than the rated 150cc/min. I use up easily half a litre after a blast on the road, or a few dyno runs. And that's injecting at 14psi

Fuel flow is estimated at 4000cc/min. so w/f ratio is 105/4000= 2.6%.

my w/f ratio was higher than that, and still was nowhere near enough :lol:
I'd need two things at this stage:
1. the Aquamist turbine gizmo that measures waterflow. I wouldn't dare lean out further without it.
2. that screw-in adaptor to secure the nozzle on a silicon hose. Can't really swap nozzles on the dyno without one.
Let's hope that the Aquamist R&D fund can stretch that far, he he... :wink:

Do you have your dyno plot at hand? If you can't post it, please describe it.

I saw clear power loss when injecting water with stock fuelling (no surprises there, eh?)
I saw clear power gains when leaning the fuelling and using WI on top
I saw greater power gains when injecting water at 8psi instead of 14psi (that WAS a suprise to me, I expected it to be the same or worse)
It took me a few hours on the dyno overall, this is not a cheap sport. I definately need more runs now, knowing what I know.
