Beat you to it Albie! Okay guys, I've followed with interest the debate over the Tornado Fuel Saver. I've had my H2 for 1-1/2 months now. Having flown pretty sophisticated aircraft all my life I'm pretty much in-tune with equipment I operate be it aircraft or truck. I travel the same trip every day..22 miles to and from. The to is slightly down hill and from uphill. It's been a challenge and sort of a game to see what kind of mileage I could get. Over 3 tanks and about 900 miles it settled down at 11.4 mpg...never 11.5 or 11.3 but 11.4 day in and day out and I treat it gingerly timing stoplights, etc. So after watching all the controversy over this "gadget" I decided to buy one and try it. Installed it last night and tested it today. Drove the first "to" leg without resetting the personal mpg. Stayed at 11.4 avg mpg although I really didn't expect it to change in 11 miles when established over 900 miles. So before the "from" trip back I zeroed out the personal avg mpg then drove the "from" trip then the "to trip and the final "from" trip. Total 36 miles. Average MPG -- 13.6! That's 2.2 mpg increase. Now I'm sure this is not completely accurate since it's only 36 miles so I'll give you an update at each fill up. But here's some other interesting observations. I saw 24 mpg instant econ @ 45 mph on flat stretch on cruise control. I saw 52-55 mpg coasting from various speeds. Silly guage but I've NEVER seen that decelerating before. And another clear difference is faster shifts accelerating from stop lights. You know those rediculous RPM's the H2 generates just getting up to speed. It now gets there quicker and shifts sooner. Don't ask me how this works. When I took it out of the box my first reaction was that I had bought that bridge someone was selling. Even though I bought it just for the test I intend to keep it. One note for those of you that might install one in yours. The instructions are pretty simple but wrong for the H2. It tells you to install it in the intake hose downstream of the air mass sensor. If you try to put it in that connection the sensor conflicts with a secure fit. The H2 intake then expands accordian style and the diameter is much larger than the gadget. I installed mine downstream of that in the hard plastic. There's even a protrusion in the plastic that the expansion gap in the gadget fits perfectly. Takes a little fiddling but once it's in it fits great and is secure. Even the instruction say to install it as close to the throttle body as possible.
So there it is guys. Can't tell you the exact theory behind it or the aerodynamics or any of those other things thats been debated. I can tell you I think the silly thing works! So who cares about theory? I'll keep you posted.
