To get the most out of the Tornado fuel saver you must go beyond the manufacturers recommended installation directions. If not you won't see any difference in fuel economy or performance. Installed the way the manufacturer tells you to do it in the directions merely protects the manufacturer of the Tornado product from possible liability lawsuits resulting in the possible increases in horsepower and the potentially reckless driving that may follow during testing of your new found horsepower.

First off- don't bother installing the unit near the airbox- waste of time. It will be too far from where it needs to be to deliver maximum performance.

Obviously what we want the most is an increase in horsepower from the rear wheels?

Mounting the Tornado further down the line will help. Mounting it near the beginning of the power chain...i.e. the very start.... the airbox... won't help much.

Getting the unit closer to the fuel intake helps.

Mounting the unit just before the gas intake will help as well.

But better still you will find if you increase the diameter of the tornado you will get more power. Just like more powerful tornadoes in real life are larger...

So if you take the Tornado as a model to enlarge, we are getting somewhere. But why stop there? Let's face it Jay Kim, the inventor of the tornado, isn't a rocket scientist. There are better devices designed to swirl the air out there made by companies with huge R & D budgets.

Lockheed, Boeing..etc..

So what you need to get is a real turbine fin and a housing . But miniature. Where can you find a unit like that? Well the military has been using these for years and they are available cheap as surplus. Some have even been confiscated from Drug Lords and are available at government auctions at super low prices!

These miniature devices are called Jet Assisted Take Off units. Again, where to mount this? Not near the air box (the beginning of the power chain)- the resultant heat wouldn't be good either.

No- optimally, near the very end of the power chain. Where is that? As close to the rear wheels as possible. Sounds crazy doesn't it? But there will be the most direct increase in force.

Here is a third party testimonial of this type of installation.

The operator was driving a 1967 Chevy Impala. He ignited the JATO unit approximately 3.9 miles from the crash site. This was established by the location of a prominently scorched and melted strip of asphalt. The vehicle quickly reached a speed of between 250 and 300 mph and continued at that speed, under full power, for an additional 20-25 seconds. The soon-to-be pilot experienced G-forces usually reserved for dog-fighting F-14 jocks under full afterburners.

The Chevy remained on the straight highway for approximately 2.6 miles (15-20 seconds) before the driver applied the brakes, completely melting them, blowing the tires, and leaving thick rubber marks on the road surface. The vehicle then became airborne for an additional 1.3 miles, impacted the cliff face at a height of 125 feet, and left a blackened crater 3 feet deep in the rock.

Most of the driver's remains were not recovered; however, small fragments of bone, teeth, and hair were extracted from the crater, and fingernail and bone shards were removed from a piece of debris believed to be a portion of the steering wheel.

You see if you buy a Tornado you should also increase your car's braking potential, tires, and downforce aftermarket fins, as well as suspension. At that cost you see you are better off selling your car and buying a better one.
