can anyone give me the scoop on Allen Superchargers? I know a guy whose friend is selling an Allen sc that he had on his Ford Explorer for about 6 months. He says it will fit my 99 4.6 2v. The website says they use the Eaton M90 in their sc's and they run about $4500 and produce up to 108 hp i think. He wants $2000 for all of it. Is this a good sc, will it fit my car, and is that a good price? john
