I'm looking to get a blower for my mostly stock 5.0. Does anyone know about these? I know it's an older model, but outside of that I really can't find anything on it. How are they as far as reliability and efficiency? What kind of boost are they capable of? I'd like to get an S-trim, but my pocket book may not allow for that. Is this a good alternative, or would I be wasting my money? Thanks.
