This was installed on a Jet Boat and removed after about 15 minutes of run time. Owner's wife complained of super charger whine noise. Cost $7500. Not sure of brand or many details. Believe it fits 6.2 GM. Has fuel rails and some other parts. Nice piece with a silver coating. Have no use for it. Thought maybe someone here knows what it is and can use it. Can try and answer any questions, but do not know alot about these.
