#59 of 332 Ancient Fuel Saver Repeat by bburton1 Dec 02, 2002 (1:47 pm)
Sorry hit the wrong button. Anyway years ago there was a crowd of snake oil dudes selling something that looked like a small propeller insert that when placed under your carb would dramatically improve your mileage. Well they had some manufacturing problems and they caused more than a few gas leaks and fires.   Wonder if the tornado crowd is related.
#60 of 332 Undercarb catalyst by oldharry Dec 10, 2002 (7:55 pm)
In the seventies there was a device with two layers of screen in cup shape (for throttle plate clearance) to replace the carburator base gasket. Claims said it 'catalized' your fuel for more mpg. Funny thing, people that tried it DID get more mpg. Big city taxi companies accomplished the same thing using the same principle. They put a restrictor plate under the carb, essentially reducing the flow though the throttle. With fuel injected cars, it would be simpler to put a block under the accellerator pedal.   Harry

#62 of 332 But a brick or 2x4 under the accelerator by zueslewis Dec 11, 2002 (5:56 am)
DOES work if you can't practice self-control.

#64 of 332 In 1988, I had a new '88 Mustang GT by zueslewis Dec 11, 2002 (2:48 pm)
that got 12 mpg with me driving an 16 (in town) with my wife driving. Go figure.

Or an egg on top of the accelerator....   Don't suggest that to our Aussie friends! Placing ostrich eggs on the accelerator will cause the vehicle's speed to max out rather quickly!   tidester, host
#66 of 332 gas mileage by 300michael Dec 20, 2002 (6:59 pm)
Drive like you have a egg on your gas peddle and use the brakes as little as Antisapate stop lights) possible. As for testing gismos, test them on a machine/dyno, since driveing to work is not a good way, because you may hit more signals or heaver traffic on ome day more then another. Also you have to figure in the cost of the devise, such as $60 or so how much gas does thay buy.
#67 of 332 Tornadofuelsaver experience on 2000 Chevy Tahoe by txmoore Feb 02, 2003 (8:51 pm)
I have real world data back from my 2000 Chevy Tahoe Limited ("old" body style), 5.7L V8. I drive a consistent mix of city/highway driving. Before Tornado, I measured my mpg at 14.9 with my previous tank of gas, although I have been known to creep up into 15.0 to 15.5 on some previous tanks.   Keeping driving habits the same, my first tank of gas post-Tornado was 14.9 mpg, my second 15.3 mpg. I didn't consider this statistically significant or sufficient to justify the $70 investment, so I disconnected the battery longer than they suggest (5 minutes) to "reprogram" the computer, I presume for air-fuel mix. After reconnecting the battery, started and idled longer than they suggest (2 minutes). So my third tank of gas after the battery trick was 15.3 mpg.   I had similar warning bells in my head from reading their marketing material, as previous posters in this forum, but was willing to run my own test under the 30-day money back guarantee. So I still have almost 2 weeks of the 30 days left and plan to remove and return for my refund immediately.   Let's say that the device does allow great improvement for the vehicles listed in their marketing material. Even if that were true, there is not a vehicle of the 2000 Tahoe type with a Vortec engine that's represented on their table of example improvements.   So I won't be installing it on my wife's 1997 Suburban then either, as it has the same engine type.   For Tahoe owners in my area wanting better gas mileage - my advice, cure the lead foot up to your stops and out of your starts. Where are you really going when the light in front of you is still red? Replies to this message: coopdeville (May 06, 2005 4:15 pm)
