Electric Supercharger Options

[VavAlephVav]

Wondering what experience anybody has had with these little electric supercharger systems like this one,

says it makes 1psi boost and gets 15 hp. surely not as much boost as a nice supercharger,
but at $400 compared to the $6,000 kit for a supercharger, I may have to at least consider it ya know.

I've seen that video with leaf blower on a dyno run as well

But the main difference when talking about air intakes is between naturally aspirated engines and engines with forced induction. While NA engines run in atmospheric pressure, therefore the air is sucked in the engine, FI engines run in high pressure circumstances, where the compressed air is forced into the engine.

Therefore no fan-powered air intake system can actually put more air in the engine, than the engine itself can suck (correct me if I'm wrong, but I believe that the leaf blowers use the fan as well). The only possible increase in horsepower is made, if you give the engine more air to be sucked and this is exactly what SRI does: bigger diameter hose, bigger air filter - more to be sucked. I guess you can say the same about the leaf blower here

Don't get me wrong, I'm not trying to be a wiseguy (nobody likes wiseguys), just trying to help understand the big difference.
