The factory GT-R fuel rails are adequate to 900 horsepower but once we exceeded that with our Alpha turbo kits the restrictions became apparent.? The AMS Engineering Team went to work by dissecting and testing ALL of the factory components and lines in our fuel flow test cell.? They diagnosed all of the restrictions and developed a fuel rail system that greatly increases fuel flow in the most intelligent way possible.? What they created is a non-intrusive, bolt-in solution capable of supporting over 1500 hp when used with a supporting fuel system.
