That "Real World", the one the kids in expensive colleges always are afraid to participate in. I checked a few videos of the keychain supercharger. Most of them just spin up, but one seems to have the two chambers joined, and may do something, at least on a 4 stroke. They were all rc car models. Mopars.. well I guess I do have one. Just because it is cute though, and I like the street rods. PT Cruiser. They make a pretty mean car, gotta watch the transmissions.
