The prospect of using a hydrogen boost to increase fuel economy was mentioned in this thread: Looking for Better MPG Tips, Tricks, and Suggestions........ but it seemed like the tangentiality was growing, so I reposted here. Im still reading the hydro boost page posted in the above thread Hydro Boost but it sure seems to me that we could use our existing AIR pumps to deliver hydrogen to the intake, rather than junking our A/C Systems as described by the jeepers who wrote the article. I cant think of a better way to keep my AIR pump and stay 'green'! /forums/images/graemlins/laugh.gif I have to confess that some rather large MPG claims are made in the article - almost to the point that my skepticism nearly keeps me from posting this here. Also, I would have liked more concrete testing evidence than was provided - however, even if a minor MPG gain is more realistic using a Hydrogen boost, it's still worth the discussion. I am probably gonna tinker with this as I have a lot of time on my hands w/ my current unemployment!
