Propane Injector System w/ Water, Need More Info!

Never knew this even existed til tonight. Here's a link on cardomain where a guy has got this setup in his 95 TSI AWD. http://www.cardomain.com/memberpage/449755/3

What kind of gains would you guys think you really get? What about regular injectors, wouldn't you still need them? LOL I dunno exactly how the engine works internally so I'm confused. :)

Propane is fairly popular. www.importpoweronline.com has some good info there. He makes a few minor mistakes in the way he represents proprane and how it works, but no big deal. Also note that you inject a small portion of propane into your intake, you are not runing on propane alone. Just adding it to your regular mixture. I have been meaning to try this for some time, since I have this thing for pump gas lately.

On my setup I would use DSMlink to control the propane injection, and use the direct port nitrous bungs on my BJs manifold to setup a direct port propane injection system ;) The auxiliary fuel control on the MAFT will automatically lean out hte mixture by a predetermined amount when the propane is on, etc. Fun project.
