Not to support this piece of shit at all (not even 1%) but to be at least somewhat observant, however that page was funny as hell. That dude didn't test the leaf blower type fan (or centrifugal), the only thing that thing was doing was, like he said, was causing more resistance. If you want something that can hold some type of pressure, like a *REAL* turbo, you need a centrifugal type fan. I only know this because I tried making a mini hover craft
