fuel genie, more power? Options

[motorpants]

bought this vortex plastic gizmo for my truck - I'll save 100Kms per tank (60miles?) on a 2000 Xterra and it do notice I have more jam at the pedal - but the guy discovered the fuel savings thing as a side line to finding more power for a carbed corvette dragster

this 10 cents worth of plastic (mine was $80 Canadian) sits in the air intake between the filter and top end of the motor - but the bloddy thing works - I'll get my money back in 3 fillups

I have PMO's on an early 911 and I am thinking about buying 6 of these things

anyway more of a comment than anything - with the price of gas these days...

Volumetrically speaking, the downward travel of the cylinders will create a vaccum which will demand an air fuel mixture to replace the void it created. The easier or the less resistance the intake has, the better the engine breaths thus we put bigger valves on heads for example. What you want is a quick in and out with the fuel and exhaust in such a way to give you the best power band your engine can opperate on. One of the best ways to suck fuel into the combustion chamber is to have the exhaust extract the gases from the tail pipe like a header system with an extractor. An extractor is like a funnel shapped pipe which spins the exhaust gases inside itself just like the water jug idead you mentioned. Just like a water jug, its on the exiting vortex like force of the water that the air gets sucked in. As for fuel economy, less air=less fule=less ass unless ya wanna put some laughing gas into the mixture.
