Water vapor injection project

Sorry, no ofense intended for those that really track their MPG's I am just saying that the used fuel is very variable with weather, hard accelerations, traffic, road deviations. If someone is in the 30 MPG range, congratulations and please share what you do to be there.

Im starting to think the fuel mix is diferent in Mexico vs Usa.

BUMP!!! for updates!

More bumps!!! Slacker!

Sorry Dr_Snooz, here is a quick update.

The result of this water injection project is that there is no impact at all in fuel economy. I set my system to very different flows of water, from 1 to 5 lts per 20 miles.
The car feels stronger while passing but that's all. I injected the water as liquid using the canister port, so the water was sucked into the engine only >1200 RPM. Then I passed the water through a copper line wrapped around the exhaust tube before and the result was similar.

From the things I have done to improve fuel economy, the only one that gave me some results was the HCS, but we need to be very consistent to keep the fuel level in the bubbler tank, too much or too little will reduce the performance of HCS.

For now, my car is just a normal car. No more hoses/switches/wires hanging here and there. One of the reasons is the hot weather, I don't like to work in the garage when there is 100+ degrees outside.

Bummer dude. I had high hopes for the vaporization. The only other wild goose chase I can think of is HHO. LOL

if you really want to make this work, you need the water injected through high pressure nozzles, not just sucked in. look into devils own methonal/water injection systems, best prices and most flexible setups, either water or methonal really needs to be setup with an rpm switch so it only sprays over 4000 rpm, or with a boost switch in turbo cars, it really does work, but you need proper nozzles and the pump which is over 300 psi, to get the proper atomization

From what I've heard, which is not much, water vapor is more for HP gains than MPG. Can it be tuned for fuel economy or no?

it's mainly to prevent detonation, normally in turbo cars, but it can also be used in high compression N/A setups, you get some horsepower gains, but the best benefit is when done right it drops the temp of the intake charge a LOT, you spray above about 4000 rpm to prevent it from quenching the charge at lower RPM

So... what does that get you? Power or economy?
