i will keep you all informed how the final product will come out i will try to get pics and

video if possable! but i must say from all the reading from you guys i am in disbaleaf that

it really works maybe my immagination wanting it to work and now sceptical LOL

You need to find out what CFM the fans produce. Then calculate the CFM the engine draws at WOT, then do the math. It'* that simple. The manufacturer of the fans will know the CFM rating.

EVERY single electric supercharger we've seen falls very far short.

well i guess it will be trial and error! or i just give up now lol

You also want to worry about the fan falling apart from high rpms and being sucked into your engine.

i dont think that it is possable, there is a screen at the end of the intake on the motor.

sorry for double posting! how do i find out the CFM the engine draws at WOT?

Well, 3.8/2(because it'* a 4 stroke)*6000 (is that redline on a L36?) = 11400 liters per minute. That equals 402.6 cubic feet per minute.

o.k. im friggin lost

It doesn't matter. What happens to a plastic bag if you hold it in front of a fan? The air goes in, then comes right back. It can backflow right back past the fanblades. Why? Because it'* not a positive-displacement type blower. There'* a return path.

The air can't do this with a supercharger. There'* no return path, so the pressure can build in the manifold in reserve for the engine to use when the intake valves open.

In other words, an 'open blade' fan won't do you any good. It can MOVE air, but it can't build pressure.

All electric fans are rated in CFM with NO LOAD OR RESTRICTION. This is how the e-ram electric supercharger scams people. They give a high CFM rating because their fan was tested in an open room. As soon as you put it in your intake, it loses far more than 50% of it'* efficiency.

If we were in a lab, I could show you a practical demonstration of this in 5 minutes.

Great explanation/analogy
It'* the same reason why true ram-air is almost impossible to achieve, right?
