If they could only figure out a way to make the gasoline spin on its way into the cylinders. Imagine the mileage and horsepower gains! Maybe they could call it the Fuel-icane or the Gas-Gust

Ok, we all have had some fun with the tornado, so maybe we can come to some good suggestions about how to increase fuel mileage. I keep hearing people in the forum talk about headers and intakes increasing fuel mileage.

Just suppose I added them and increased the amount of air going through the engine by 5%. That would also require a 5% increase in gas to keep the fuel mixture the same. Now at 60 miles per hour I am turning say 2500 rpm. That means to maintain 60 miles per hour and 2500 rpm. I have to now put 5% more air/fuel through the engine. And I will see a 5% DECREASE in fuel mileage at every speed. Yes I would have more power but less fuel mileage.

The way to increase fuel mileage is to increase the EFFICENCY of the fuel combustion.(excluding weight loss for this example) Car manufactures spend BILLIONS on trying to get better efficiency. The reason we have fuel injection, electronic ignitions, and CPU controlled engines is to get better fuel management and increase the fuel burning efficiency resulting in better fuel mileage.

Just putting in more air will NOT help mpg.

Dave, in fact, its the exact opposite. Your engine will only suck in the amount of air it requires to burn the fuel (thanks to the sensors). Think of it this way, take a drinking straw and suck air through it. Then take a piece of garden hose the same length of the straw and do the same thing. Which is easier to do? You use more energy to suck the same volume of air through a straw as with the hose. The same applies with the intake. It's easier to pull a volume of air through a cone filter than a traditional filter because there is more surface area for the air to pass through. Therefore, more air can get to the engine in a shorter period of time. The same applies to exhaust. Bigger pipes and less restrictive mufflers allow more exhaust to exit more easily. The combination makes for a more efficient process. In addition, colder and more dense air burns fuel more efficiently.

 

Many years ago, I came up with an idea for a "Rotary Valve Engine", that did exactly that! This idea eliminated valves, valve springs, camshaft, and lifters and pushrods (OHV engine). Long story, but Honda stole the idea from me....

 

Ctboyle, I am stunned at you knowledge. I give up !

The straw and the hose is a bad analogy. The straw is restrictive, making it hard to suck air through, compared to the garden hose. With the OEM intake,
IT ISN'T restrictive, because it's designed to flow the air volume required by the
engine. A better analogy would be the garden hose, which is easy (not restrictive), and then try a 4" diameter pipe....no difference with the 4" pipe, because the garden hose will flow all the volume of air you can suck!

 

Well i didnt really expect you to give up so easily. I guess they did teach me something in college....actually I'm more amazed that I actually still remembered something i learned in college. Guess its not true about what they say alcohol does to brain cells.

 

my ex's mom got one of us those about 5 years ago, man i cooked some great ribs with it, damm *!^** took it when she left

so now im stuck in an apartment using a dang charcoal grill with no experience and am producing freeken wooden planks for ribs.

 

tomtoc, I am sure none of us are trying to make you feel bad just as Dave257 said we are just having fun. Those tornados have been a funny topic for a while on this board.

 

...i can take a joke. i know PC's well, not cars. i laugh it up when people ask dumb questions about their comptuers and am sure it's the same thing here. people on computer forums laugh how people pay retail for computer as opposed to building the themselves. i try to equate it to people doing repairs on cars themselves. mechanics (like yourselves) laugh at people that take their car in to get their oil changed. i don't, but every other computer geek does.

anyway, no offense taken.

 

thats like u putting off a virus update....

Nah, more like pushing the "Turbo" button on his old 486 PC and expecting it to ZZOOOMMM.

 

I've found that the tornado works best when used with 2 tb spacers stacked together and in conjunction with a set of splitfire spark plugs and a quart of slick 50, now thats a reciepe for success. Seriously, the tornado must have shown some benifit on some vehicle somewhere down the line for them to run with the idea like they have. So I would bet a dime to a dollar it worked on something. Like the tb spacer, we know it worked on carbed engines back in the day, it's also a popular upgrade on jeep inline motors. I installed a airaid tb spacer on my 02 wrangler 2.5 and it seemed to lower the power band a tad, then but on a 4.0 tb and increased throttle response. So putting a tb spacer and 4.0 tb on a jeep inline 2.5 4 cylinder did make a difference and was a nice little upgrade. I've tried tb spacers on a 5.4 v8 and a 4.0 v6, and "nothing", well, I can't say nothing, it did make a cool whistle. So this product may do something on some engines, but they sell it for the masses as if it works on all engines. It will increase hp on any engine if you tap the tb spacer for a NOS nozzle, but thats the only way hee hee. My point being, that the tornado must have worked on something, it can't be BS from the get go, they must of had some bases for it.

 

i used to do this with doom and it would play in 2x speed. oh the days. and wendell, i sometimes feel that the k and n filters are the same as the tornado craze (im not starting a fight here ppl so lay off) because of less filtration.
