Estimating Power Increase Due To Boost and Needed Water
A few years ago Howard recommended 325 cc/m WI for 400 whp but gave no % of water to fuel. My calculation for my stock port GT35R at 16 psi based fuel mass came to 322 cc/m WI at 20% of fuel.
I am in the process of bumping my pressure to 18 psi. My estimate is that this will give about 425 whp. Thus is 345 cc/m WI good?

Pistons are for pussy's
When i was going Single last year Howard recommended me 400/500cc water for 450-500whp.
I think for 425whp you should at least up it to 400cc/m to be on the safe side.

(1) Their calculation determines the maximum water flow you need if you max out the fuel injectors based on a fixed % of water vs. fuel flow.
(2) Then you would need a system that flows water at that % based on injector duty cycle change as you boost.
(3) I have a AEM system, not Aquamist.
But it might help someone.
