Water/Methanol Injection

Yup water injection is awesome. More effective than e85 in my personal opinion. I tuning my car one night (rb30det skyline) and it had some pretty decent 440cc injectors in it. I had a 50/50 mix of e85 and 98 and to get my car running mint afrs i had maxed out my injector duty cycle at about 10psi boost at high rpm.
I then used up all of the fuel and got some 98 i was trimming back all the fuel tables and found that i could run the same boost and same power running at 70% injector duty cycle.
Now at this point if i had installed the water injector kit (which i didn't because i didn't have the correct nozzle sizes) I would have been able to run one whole point leaner afrs without having to worry about detonating (From 12.8 to 13.8) and i could have thrown much more timing advance without detonation. All this plus the benefit of having cooler cylinder temps and a constantly steam blasted carbon free combustion chamber.
All these benefits with nothing much really to lose.
I hear a lot from people with excuses about why they didn't install water injection. Oh im not using this as a drag car. Oh e85 is god to me. I have a big intercooler im good mate. All just uneducated comments that prove most of these guys are painfully ignorant , or simply just couldn't be bothered to learn about how it works.
You get people who can't justify spending 200-400 bux on something that none of their mates are smart enough to use on their cars. Instead they will go spend 1000 bux on a e85 fuel system with swirl pot and shiny lines big expensive untunable injectors. It doesn't make much sense to me.
