Well, I opened the bonnet today on my V6 to inspect if I could find space for Water-Injection and it seems that I was in-luck.

Since it's a sucky V6 (a powerful one), 270hp or so it would be interesting to attempt a Water-Injection build on this car. The car was bought as a muck-around toy rather for any practical transportation use.



It's a 20mpg around town, 30mpg freeway. It would be good to get more.

On such a car it's worth doing. I'm pretty sure that hacking the IAT sensor is the way to temporarily go leaner. But the o2-sensors eventually reset during the calibration phase which I'm led to believe is running at constant speed 80kmh+. I've used o2-sensor extenders in the past, they did achieve a change in economy.

To come will be photo's of it having a Water-Injection system.
