Ghetto Blower for your car.

That's pretty funny- All they are creating is a lean ram-air effect, not boost. Some leaf blowers claim 150+ MPH air speeds. And the guy shooting Nitrous into the leaf blower is really just cooling the airflow even more since the gas is so far away from the cylinders. Pretty surprised at the 30+ HP gain though. Nitrous injected into the air/fuel mixture adds more oxygen. More oxygen burns much hotter than the normal 14:1 mixture the engine is tuned for thereby creating more power. When you add (inject) more nitrous in the correct manner, you also have to add more fuel or you will create a dangerous lean condition in the engine and cause detonation.

There's good and bad about doing what these guys are doing:

Good:
They are making ram-air into the intake, which gives you a cooler intake temp and avoids engine temperature issues that can create heat soak.
This method forces more air into air cleaner thereby eliminating existing intake obstructions and giving better performance.

Bad:
They could really mess up the MAF sensor doing this.
They could lean out the fuel mixture doing this with the engine at high RPM's.
The computer will sense a lean mixture at the O2 sensor from all the air being ingested into the engine and will attempt to fatten the mixture at the injectors, based on the preset fuel curve in the computer. Without a modified fuel pump, Fuel MAP or larger injectors, again they could create a lean situation very quickly as the engine runs out of fuel volume. Engines will always produce more power as you lean them out, but you run into risks at some point.
