The Short Version
A thought came: What might happen if we negatively ionized some of the air going into an auto or truck engine?
About a year ago I started doing it, on my 1998 Chevy Tahoe. The results are very interesting. I have what feels like quite a bit more power at the pedal, some improved gas mileage too, much better dead-of-winter running, and the ability to run E-85 gasoline with no loss in power. Right now my rig uses fourteen 12VDC devices intended to be built into home or auto air ionizers; a friend has two, and I am preparing to add two or three to my sweet wife's Ford Focus. The most surprising aspect so far: the engines are running cooler! We are seeking solid theory as to how and why.
Some might wonder how this is possible. Well, there is inspiration; and then my sweet wife Lori made a deal with me a long time ago, in not very different circumstance, "Just don't blow up the car." Much good!
