Suncoast GM-1057-3D "McRat"
Often referred to as the ?McRat? it has set numerous records at the strip since its? inception in 2005. Our #57 series incorporates a modified OEM stator and is coupled with the "Velocity Series" impeller. It allows good turbo spool-up with stock size turbos running mild tunes and also offers more efficient fluid coupling than our #56 converter. If you?re running the larger turbos and the wild tunes and need to spool see our #55, #58 or #59 series converters.
