#33 of 332 A list of dirt cheap accessories to noticably improve mileage by eharri3 Jan 22, 2002 (9:47 am)
1) Ankle regulator: special computer surgically implanted in right ankle that sends messages to right foot to carefully regulate use of the gas pedal.   2) For manual transmission cars: Wrist regulator;another specially designed computer to be implanted in the right wrist that sends special signals to your hand to tell it to shift earlier and avoid frequent downshifts on highways.   3) Check book regulator: Yet ANOTHER specially designed micro computer that is automatically activated whenever you open your checkbook at a car dealership and tells you to buy a more fuel efficient car.   4) Feet: They normally come in pairs, and can save on fuel costs by allowing the user to walk when one's destination is not far away and it's nice out.   5) Cruise control: Can be used to set speed at 60-65 mph, where fuel economy is optimal for most vehicles, rather than at the fuel sapping speeds of 75mph or greater that many who are on the lookout for mileage-improving accessories usually drive at.   6)Backseat driving spouse, whose nagging instinct is automatically triggered by an electrical impulse whenever speeds exceed legal limits or sudden bouts of rampant accelaration occur.

#36 of 332 Tornado device by autobell Feb 09, 2002 (10:59 pm)
I was as skeptical as anyone when I first saw the device, actually laughed at the student in class because it couldn't possibly work as claimed. Well to my surprise after installation some results were worth investigating. Started testing on our Clayton chassis dyno and recorded positive results in almost every vehicle we tested. Remember I am a racer and don't really worry about MPG. Saw some interesting HP gains on the dyno and lost them when we removed the device, remember this is all done in a 10 to 15 minute test period. Please don't bad mouth this device until you have actually tested it in your vehicle, don't forget to disconnect your battery to erase ECM memory so it can relearn the fuel trim curve faster.

Seeing HP gains on a chassis dyno still doesn't mean it works in the real world.   1) Which vehicles did you test? 2) Were they stock vehicles, since you're a 'racer'? 3) Were the tests all conducted under the same conditions or was the humidity/pressure/temperature of the air varying from test to test? 4) Were all of the engines and drive trains warmed up to the same operating temperatures each time? 5) Were the vehicles you tested fuel injected or carbureted? 6)What is an 'interesting HP' gain?   The only reasons the tornado would work is if the engine has a very poorly designed intake system. There is no reason to 'swirl' air any more than what the intake runners are doing in most cases. Go sell snake-oil in another forum please!

IF they really worked the factorys would install them on all new cars. The factorys will stop at nothing to increase fuel enonomy 1 or 2 MPG.
#39 of 332 Stopping at nothing by scotian Feb 13, 2002 (10:31 pm)
Why then do they sacrifice the gains of an unrestricted air intake system for the reduced engine noise (while accelerating) that the stock airbox, etc., provide, with all their baffles, chambers, and twisty-curvy air paths?

i have 250k miles on my 94 accord i have stayed with the manufacturer recommended oil 5w30 dont burn a drop and its the best way i know how to save gas after your regular maintenance schedule it works on hondas
#41 of 332 Thanks Guys by orcinman Mar 07, 2002 (9:06 pm)
As a starving college student, I was actually considering installing one of these gimics in my Elantra (the "tornado fuel saver"), however common sense and this forum have snapped me back into the realm of reality.   Thanks guys. I wish Ithese gimmics worked, though.
#42 of 332 air filters? by oldharry Mar 10, 2002 (8:48 am)
I see the claims for improved power/economy for aftermarket air filters, and ask, Has anyone you know attached a digital vacuum gauge ABOVE the throttle plate, and driven the vehicle at constant speeds on the same roads before and after the change? If the filter is really reducing restriction, there will be measurable vacuum above the throttle with the stock filter. Some years ago I used a clear plastic tube with a teaspoon of water for a manometer, and could not measure a vacuum above the throttle on my car at idle. The system did not allow me to test it under load with any equipment I had available at the time.   This was in the late sixties when self proclaimed "experts" were turning their air cleaner covers up side down to "increase air flow". Some of us at the school did an experiment (U S Navy fleet training - mechanics, Davisville Rhode Island). We asked ten of our students if they would participate, and not look under their hoods. We had them fill their tanks every Monday and Thursday. We checked their oil that day, and either installed the covers correctly or turned over. They were told to drive normally, and report the amount of fuel, and miles on the car at each fill up. Without exception, the times when the cover was upside down for "more air" the fuel economy went down.   The reasons most likely were:   1. The carbuerators were less efficient when the air heating system did not work. 2. The engines required more throttle to produce the same power when not fully warmed up but after choke opened. 3. Some restriction was required to insure proper mixture with the carbuerator.   I now tend to be very skeptical about claims for air filter devices. The manufacturers can reduce restriction if there is enough to matter, by simply increasing the size of the flter element. The only possible time there could be a problem IMO is wide open throttle.   That problem actually did exist in the sixties on some Chevy II's. GM accidentally put air cleaner housings for 4 cylinder engines on some sixes. The tsb said to measure the diameter of the intake opening and replace with the appropriate part number if wrong.   Harry
