Ozone......
 

The "magic spark plug" thread gave me the link I've been searching for.....

Basically, this guy is saying that you can pull the ozone (created inside the distributor cap) into a vacuum line, and that this ozone will increase efficiency. Any ideas whether this would work?? Or is it just as hokey as it sounds??

Theoretically, but no
 

From what I understand, ozone (or O3) offers more oxygen for the combustion, but the miniscule amount wouldn't do much. Engine oxidiation can occur, damaging engine components. Hydrogen runs along the same principle (but I've yet to see an improvement and engine longevity argument for either). The change in FE is likely due to a vaccum leak.

Check out an old Thread on the subject.

RH77

The ozone inside the cap is created from the oxygen in the air, so you aren't really adding more oxygen. You are just adding it in a more reactive form. The amount of ozone generated would be reeeeeeaaalllly small compared to your total O2 consumption.

Interesting read, rh77. However, I did not see any actual results, just a bunch of speculation. Guess I need to look for the old dizzy cap I pulled off and give it a whirl.

Also, is this true about the ozone being corrosive to aluminum?? I'm reasonably sure that AMC used cast blocks/heads....there's not a lot of aluminum in my motor. Does this mean I don't need to worry about it??

Can't hurt to try it. The only aluminum parts we have is the intake manifold. Everything is pretty much cast iron. I think you still have steel pistons too.

I read up on that but, I am wondering, when you suck air through the distrib. cap it is unfiltered, so you are sucking dirty air into your engine. Plus I can not believe that such a small amount of ozone could change your mpg.
