That sounds about right. Ive heard the same, but there are always trade offs with intercoolers and water injectors. All that is kind of over my head.
Ill have to stick with the stuff I know for now.
I have a hard time believing 23hp, as My NOS system in my race car would last for 10 laps and I would use it on the straights. by the time the bottle was half empty, the hp gain went from 50hp down to about 25. even 25 was slightly noticable. I cant imagine a shot of water keeping up with a 25 shot of freezing air and Gasoline!!!! Maybe the 23hp is what you can gain by turing up your boost and getting the hp that way, and having the water cool it down to keep the engine alive.
NOS was great, but that was only good for 10laps, and cost $40 to fill the 10lb bottle. I still cant believe that 10lbs of "air" was stored in a bottle!!!! very cool. (pun intended)
so, in otherwords, if you are going to have an injection system, may and its not to work with the turbo/supercharger, then use NOS. Otherwise, thats a lot of plumbing for a small gain, I would imagine. Yes, show us the dyno runs. If I can get 23hp with my race car by shooting in a spray of water, Id do it if it was safe.

There is some benefit to water injection, esp. if you run high boost. But water injection is less effective than intercooling. Intercooling in conjunctiuon with water injection. well! That's just going over board with the boost knob for safe streat use (but I like the guts of those guys who have money to buy a new motor when theirs blows up). There was an article in EuropeanCar mag a few months ago, that discussed water injection used on the author's turbocharged M3. If memory serves me right, the intercooling lowered intake air about 100 Deg. F while water injection lowered it by 50 Deg. F.
For another twist! On large combustion turbines (jet engines essentially) used in generating electricity and compression of fluid for pipe transport, "fogging" is used to increase horsepower/efficiency. Fogging is water injection with fogging nozzles. Siemens has developed another system similar to fogging, but it is essentially spraying water into the intake at a very specific amount, such that it atomizes prior to combustion. I think that's right..the mind is a bit foggy these days..so don't hold me to anything
