REFLECTOR: Water Injection

[Mark Magee]

I want to say 8.85 to 1. This is from memory. It is the 300 HP angle valve.

I have used them in the past in autos with good effect, and studied their uses in other applications. The numbers these http://www.alcoholinjectionsystems.com/Naturally-Aspirated-Kits/c25/index.html folks post are in line with what water injectors can achieve from my past experience. Anyone used one on a Velocity/Canard/Flying aircraft?

So a 6 gallon tank (in the keel?) would easily handle a long cross country. In cold weather 50/50 water methanol I would think preclude induction icing, but you could always just turn it off it it was cold enough and you didn't need it.
