it is sorta interesting, what if you combined it with nitrus, so you get nitrus w/ 6psi of boost at the push of a button......

 

it can't be that hard to install. it looks like they just run it b4 the aif flow sensor and dont' bypass it for normal driving. bigger injectors maybe...and an adapter to fit the compressor to the end of the intake. add batteries and hard core wiring.....i think its a pretty cool idea, simple in concept, complicated in application
