I will be the first to admit that I am a mechanical noob...it is an engineering marvel that I was able to lift my own silverado a few years back...but when it comes to under the hood, I really am lost. Point being, I have seen a couple of "electronic superchargers" advertised here and there (as opposed to gear-driven ones). ANy comments? They seem to be < $200 which is one huge plus, but are they all smoke and mirrors? ANy long term drawbacks to the engine itself?
