just adding water/meth on a honda will not net you any gains without tuning for it...IE leaning out the mixture and adding timing (effectively the same as switching to race gas)

generally, spraying water/meth decreases the power of the engine (no I don't have any concrete numbers) and what I always wondered is if the extra boost gains offset the losses?

Because that's what the cool kids do.

it almost seems that buying all the separate parts could get you into a nickel/dime situation pretty quickly..

has anyone here used MAF based controllers for water injection?

I think you'd be better off with a Throttle Position vs MAP system. Having a transistor control the pump flow based on MAP voltage and a variable resistor on the throttle.

Got around to installing my ebay kit today, still have race gas in the tank though. Once it is gone I will see how much boost I can get away with on pump with my normal amount of race gas timing.

I use the autospeed build it yourself kit on my datsun. So far I've kept the stock motor together running low 11's. After trying water/meth for two years, I've switched to 100% meth and lowered my et by 1.5sec. I have to spray a lot more with the meth, but it works much better than anything with water. A local tuning shop won the car craft dyno challenge using water only, but with meth they gain another4-500hp over the 1300 or so they made at the contest.

I got my car mapped, running a snowboost kit, the 175cc jet comes on at .8 bar boosting 1.4 bar with Pump Gas and 50-50.

Eventually wanna run 1.8 bars on this setup....
