Has anyone ever used one of those tornado fuelsavers. i was thinking about getting one but didn't know which was best or if it was worth the money to spend on it.

this is the one i was looking at,

From what I've heard, they're a waste of money

 

Gimmick....

 

Waste of money, save up your money for a Cold Air Intake from K&N, AEM, or Airaid.

I have one and i dont think its a gimmick ~!

 

well im putting an aftermarket cold air intake on it but i had heard from a few people that it worked pretty well. Just wondering if anyone had one on their blazer.

 

There rubbish, They tend to break apart and can damage your engine.

 

there have been numerous threads on here about the tornado and similar products. If you insist on buying one, just send me the money you were going to spend on it, and it will have about the same effect.

 

You realize that most if not all of the vortex that it does create would get destroyed by the throttle body right? I got a chip instead and it actually did help. My next upgrade would be CAI. I was thinking about those TB spacers that were milled to create a vortex after the throttle though. Anyone know anything about those?

Even a spacer that makes a feeble attempt at spinning the air after the throttle body won't make a hill of beans different at the valve or in the combustion chamber. These engines are already designed to create a swirl effect (vortec-->vortex) as the air passes by the valve, filling the combustion chamber. This is all done with intake runner design in the transition to the valve.

I urge anyone that *thinks* these products make a difference to read up on them. They are a placebo. I spent money, therefore I got a performance increase. I have read numerous articles in auto magazines about many of the available fuel savers. The simple fact is that if these products did what they say they do, we would already have them on our vehicles. With the ever increasing CAFE regulations, every automaker is working very hard to increase their corporate average fuel economy. If these things were so free and easy, wouldn't you think they would be in general use?

I myself had throttle body spacers made by PowerAid on my old '94 Intrepid 3.5L 24valve v6, an engine built for high rpm power with the peak torque occurring at a relatively high RPM. Supposedly, the helix cut into the ID of the spacer was supposed to create a vortex in the cylinders for better fuel/air mix. Well, I made up some spacers to sell and figured I'd try my own design with smooth bore on the car. No difference what-so-ever to the helix bored spacers. Same gain in off idle torque, same loss in high rpm power. The only difference was my spacers didn't whistle like the PowerAids did at part throttle (oh darn). With the already very low rpm torque peak on the 4.3L v6, a spacer would be a bad idea. Spacers increase the runner length. Increased runner length serves to lower the torque peak in the RPM range. The increased length also cuts down on the engines ability to breath at higher RPM which reduces its high rpm power.
