We were making fun of those in a thread in the BOL a few weeks ago. Let me tell you why it won't work. It claims to deliver up to 220 CFM of airflow. Your engine will be sucking in air faster than that. In order for there to be an increase in power, there has to be boost. Boost is when there is more air being forced into the engine than the engines vacuum, combined with gravity, demands. In otherwords, it has to be able to supply MORE than the engine requests. Whatever method you use to create the boost has to be the only method that air can enter the engine, otherwise any boost would be pushed back out into the atmosphere. In otherwords, this little gadget would have to be inline with the air intake path. At WOT, your engine should be pulling in at least 350 cfm. This "electronic turbo" can only move 220 cfm. That means it would actually act as a restriction, and slow you down.

Plus, boost is created by compressing air. This gadget is more of a fan, which pushes air, but isn't strong enough to compress it.

Now, let's say, hypothetically, that you were able to get a leaf blower that moved enough CFM, and had blades that were tight enough to compress the air, and that the path the air would travel was sealed, and it all worked, what do you think would happen when you just turned the fan on or off? To add boost safely, it needs to be added at a proportional rate to the rpm increase, which is why a system driven by the engine works so well. Blowers create more boost the faster the crankshaft spins, and turbos increase boost the faster the exhaust is expelled. This also gives the fuel system a fair chance to keep up with the increased air. How do you propose controlling the fans speed in relation to driving conditions? What happens when you have to suddenly stop? The fan keeps pushing at the same speed. You could have a wastegate of some sort, but with both turbos and blowers, their boost deminishes automatically right after the engine speed drops. How would the fan know when to reduce it's speed? It would need to be variable, in tune with the rpms.

Something else to remember that might make it all easier for you is this: The only thing a blower or a turbo do to your engine is increase the displacement. That's it. At sea level, 14.7 pounds of boost doubles an engines displacement, ie: turns a 302 into a 604. So, in order to create any power, your source of boost has to be strong enough to pack more air inside the engine than it would normally permit.

I hope this helps, and saves you a few bucks.

Take care,
