Someone correct me if I'm wrong, but isn't this one of those hokey devices that you put in the intake tube??? If it is, don't waste your money.

all it will do is cause resctriction in your intake and add friction. You will lose power not gain it.

It's a giant vortex of air created by 2 different pressure lines meeting, resulting in a circulating mass of air that rapidly increases in speed and intensity.... Ok... now that the obvious is out of the way lol... I'm only kidding, not ragging on you or anything.

As for the actualy Tornado Fuel Saver device.... it's a piece of crap. My roommate and I (being curious engineers) tested this device on a flow chamber in our labs in the engineering building a few years ago, and the results were not good. The device actually restricts the natural air flow designed on todays modern cars.

The reason for this is simple - the Tornado causes the air to vortext prior to entering the throttle body... the throttle body disrupts the air flow anyway and the airflow changes directions as it enters the intake manifold anyway so causing a vortex earlier in the flow path does nothing but cost you money and not increase your efficiency.

If you want a good way to control fuel economy there are 3 things I could suggest.... free flowing exhaust system (headers, cats, muffler), different CAI likea C&L, BBK, or K&N, and the most important of all..... control that right foot (i know... these cars make that VERY hard because they are so much fun to drive).

Point of this long post... the Tornado Fuel saver does nothing to save you fuel, in some cases can actually COST you more money in fuel... and you are automatically out the $60+ for the piece of junk itsself.

+1. There are other ways too save some gas money too. Use the closest grade gas to what your car is tuned for. DO NOT go higher, and DO NOT go lower unless you have to. If you have to make a choice between the two, go higher it wont cause any immediate "damage" and really isn't dangerous for your engine. Going lower is dangerous to your engine, but don't worry about that stock cause i have never seen anything lower than 87 ( what our cars are tuned for stock). Going with say, 93 can cause an uneven/incomplete burn which can create carbon deposits and other little problems that will decrease your mileage/longevity of your engine. Make sure you keep track of your maintanence also. Fuel filter/oil changes/oil filter/spark plugs etc. Keeping those clean and in good condition will save you mileage and headaches.

oh....then go one grade higher. You are probably pinging because the stock tune is likely a little conservative so you can use 86 stock, but when you add the s&b you increase airflow, even with the stock diameter maf-s housing, which means the engine thinks you are still getting the same amount of air into the engine as you were even though you are getting more. Result = lean a/f ratio. Lean a/f ratio and lower octane gas than you are tuned for = knock city. Step up to 89 or whatever is the next level up and see if you still get knock. Make sure it isn't just your exhaust too, i thought i was getting knock and then i found there was a tsb for the front hangers being loose and the mid-pipe banging around making a sound right beneath the center console from about 1900-2500 rpm's that sounded just like knock, but i went down there and fiddled with it a bit and tightened and the sound is gone.

(replying to your pinging problem i saw in the other thread)

thanks bro, but the funny thing is tht the pinging doesnt increase when the engine revs up.
