seriously...if it were that easy, don't you think car manufacturers would do it. 2.2 amps is not enough to make the kind of air you need to feed an engine.
Eve try to inflate a tire with a 12v compressor? yes they advertise 225 psi but the cfm they can produce is so low. it takes forever to inflate your tire.
Then there's the camping inflator...producing lots of CFM but low pressure, again working off 12V.
You'd need an enormous electric motor, with much more current draw and a very high tech impeller (appropriate bearings) to produce enough CFM and a reasonable boost pressure to make a difference...would be to costly and ineficient or else car manufacturers would have mess with this, as they have all other "tuner" mods.
