The Garrett G47-1650-80MM/120 Supercore is built for enthusiasts chasing extreme horsepower with a platform engineered from the ground up to outperform its GTX Gen II predecessor. This configuration pairs the 80mm/120mm compressor stage with Garrett’s redesigned turbine technology, making it the choice for builders who demand both massive top-end capability and improved response. It arrives as a supercore assembly with compressor housing and V-band outlet already fitted, streamlining the path to a serious big-power build.

Performance & Application
The G47 platform is engineered for extreme horsepower applications, and this 80mm/120mm compressor configuration is positioned to support nearly 1850 horsepower depending on final build setup. The redesigned Inconel turbine wheel with optimized G Series aerodynamics delivers significantly more flow than the GTX Gen II it replaces, while the one-piece aluminum center housing reduces overall supercore weight without sacrificing durability. Builders will benefit from improved spool characteristics alongside the massive top-end flow capacity, making this a strong option for high-boost, high-horsepower applications where both response and ceiling matter.
