I have searching device to saving using gas, and I found this ->http://www.khaos.ph Anybody know what a good device like that ?
info :
KSTC is an air-regulating device which introduces the right amount of additional air to the engine to obtain the proper air-fuel ratio for better combustion. KSTC has been cited with a Presidential Award as the Most Outstanding Invention for Transportation & Environment during the Filipino Inventors Week, Nov. 26-30, 2003 at Philtrade , Philippines .
So, basicly, they invented a supercharger.
I don't know what's different about that one, but a normal supercharger can improve gas milage and engine power by around 30%.
They're quite worthwhile, I'm trying to custom build one for my truck.
what about with you custom your self ? how ? in the engine or what ?
thanks

So is this a small supercharger that will not sap too much power from the crank? I figured that superchargers sapped some of the power it generates to keep it going, but if they give too much boost it will lean the mixture too much and you would have to force more fuel into the engine. but i can understand when you limit the boost you may be able to improve the economy of the car. but I never really read about anyone ever using them in that fashion, not today anyway, I guess i'll have to look around. I would think if you wanted to try to improve the economy you would use a small turbocharger that way it uses the exhaust gases to turn the turbine and then limit the boost just to get a cleaner burn. anyway, Most things i see about improving you your gas mileage is a bunch of crap. Let me know if you find something first hand.It's nice, if it can really save the gas, we can save a lot in refilling the gas, but, how much is the device?
Theres an american show on the discovery channel called 'Mythbusters' where they tested a whole bunch of these fuel saving gadgets and they all proved useless. The vast majority increased fuel consumption, I think one device helped... by about 0.5%!!!! they are really not worth it! save your pennies for a bit of extra fuel 
JB well it depends on which superchargers they've tested. I really don't think they would buy a really good one for only one show, so don't believe that "Mythbuster test". Anyway, think logicaly. Same amount of fuel+more air=more power (without aditional consumption of gas).Push a pedal less and you get same power as without a supercharger but with less fuel consumption. How can you not save gas with it?

Basicly, I'm building one onto the air filter cover. It's not technicly a supercharger or a turbocharger, although it does the same thing. This one will be electricly powered. (Basicly, a leafblower, power inverter, and throttle-sensitive dimmer switch.)
A supercharger does use some power to operate, but that power is negligable; less than that of the alternator or A/C compressor. The benifit, though is huge. It makes the engine compression higher, so that it burns more efficiently, much like a diesel engine.
It also has some other side benifits, such as making the engine run better at high altitudes.

Thanks for your answer and the linki have to check that, sound very interesting
Khaos Supercharger... It ain't that expensive. 
Another product that's also sold in the Philippines is Car Vortex. I think there are more that I don't know of. Actually to the darius who said same amount of fuel + more air = more power.
Completely wrong, you have to burn more fuel to get more power. think sensibly, if all the fuel is being burned then adding more air will not increase the amount of fuel burnt. If you dont burn more fuel where's this mystical extra power coming from? To get more power you must also add more fuel.
ECUs are used in most modern cars to regulate the amount of fuel aded to the engine. Manufacturers take great care to ensure that these ECUs are programmed to give the maximum amount off efficiency. Turbo/Superchargers work in conjunction with these ECUs to provide the correct amunt of fuel for the air being taken into the engine.

Engines do not run at 100% efficiency. Some of the fuel in the cylinder is never burned, and ends up coming out of the exhaust (That's why exaust fumes are flammable) A supercharger increases the percentage of fuel in the cylinder that is burned, making the engine more efficient, and therefore more ecenomical and powerful. I very much suggest you visit the link I gave you previously.Perhaps you should read the link you posted, I just read it and it confirmed everything I just said and did not mention anything about increasing fuel efficiency. When they talk about increasing the efficiency of the engine they mean amount of power per unit capacity of the engine, not miles per gallon.
I'll provide you with some quotes from your link
| Quote: |
| Another way to add power is to make a normal-sized engine more efficient. You can accomplish this by forcing more air into the combustion chamber. More air means more fuel can be added, and more fuel means a bigger explosion and greater horsepower. Adding a supercharger is a great way to achieve forced air induction. In this article, we'll explain what superchargers are, how they work and how they compare to turbochargers. |
Note where it says "more air means more fuel can be added"
Also
| Quote: |
| Getting more fuel into the charge would make for a more powerful explosion. But you can't simply pump more fuel into the engine because an exact amount of oxygen is required to burn a given amount of fuel. This chemically correct mixture -- 14 parts air to one part fuel -- is essential for an engine to operate efficiently. The bottom line: To put in more fuel, you have to put in more air. |
and
| Quote: |
| This forces more air into the engine, providing a "boost." With the additional air in the boost, more fuel can be added to the charge, and the power of the engine is increased. |
right.. you're not increasing the fuel efficiency, you're increasing engine power.. which in and of itself isn't a bad thing, but it's not going to pay for itself over any length of time, unless you consider the value of more pulling power
another thing to consider is durability.. generally these things stress the engine more and cost more money down the road.. which is why you don't see superchargers or turbos on most cars
if you want to save money and increase your fuel efficiency, make sure your tires are properly inflated and your spark plugs are correctly gapped.. and never ever use those engine additives that they sell on late-night infomercials
