Garrett G47-1550-76MM/109 SUPERCORE ONLY – P/N: 880547-5023S w/ Compressor Housing w/ V-Band Outlet

The Garrett G47-1550-76MM/109 Supercore is built for enthusiasts and shops chasing extreme horsepower without sacrificing throttle response. This configuration pairs Garrett’s latest G Series turbine technology with a 76mm/109mm compressor wheel and a V-Band compressor outlet housing, making it a serious foundation for high-output builds that still demand fast spool. It’s the right choice for anyone upgrading from a GTX Gen II platform who wants more flow and quicker response without redesigning their turbo mounting.

Performance & Application

The G47 Supercore is engineered for extreme horsepower applications where both top-end flow and boost response matter. Its Inconel turbine wheel and aerodynamic improvements deliver significantly more flow than the outgoing GTX Gen II design, while the one-piece aluminum center housing cuts rotating mass for quicker spool. This makes the G47-1550-76MM/109 a strong fit for high-boost, high-power builds that still need to feel responsive on the street or at the track. Because its outline is interchangeable with GTX Gen II turbos, it’s also an ideal upgrade path for existing GTX-based installations.
