Just a bit of FYI...

While I was visiting my folks over the weekend I paged through a recent issue of Popular Mechanics that my dad had in the garage. Their guys did a series of tests on several popular devices that claim to increase fuel economy. They strapped a Dodge Dakota pickup onto a dyno and made several runs to determine horsepower and fuel economy. They then installed the different devices onto the truck and made runs to determine the change, if any.

I'll post the actual numbers later when I can get my hands onto another issue of the mag. But suffice to say that none of the devices increased fuel economy even 1%, and most robbed the engine of horsepower (up to a 20hp loss in one case). So before any of y'all try the Tornado, fuel rail magnets, after-market fuel atomizers, or any of those other items claiming to increase fuel economy you should know it's all BS.

 

Thanks for posting. I looked up the article on PM's website, here's the link for those who would like to read it:

Thanks for the link. Kind of worries me about the water injection dropping their horsepower, I thought it was a proven technology.

 

water injection is great when tuned... look at the kit they used though, it doesn't have a pump or anything, it's ran by vacuum on a n/a engine? hell i could tell you it wasn't going to work just from the horrible setup they were using.

get them a turbo or s/c car with a pressurized water injection kit (like all decent ones are) and test it out like they were meant to be tested. when i was setting mine up i was advised not to even have it kick in until i hit 8psi, once it kicked in though, the gauge hit 12psi like it was nothing.

 

it is but on a N/A engine its already sucking in cool air more or less and its not being heated. On F/I

engines when air is compressed it heats up and makes it less dense. Water injection will cool the air

making it more dense allowing for more fuel to be added making more HP

 

Finally some one proved it so now maybe people will stop wasting their money on this BS
