Built for teams chasing four-digit horsepower numbers on the strip, the Garrett G55-1950 88mm Supercore is the foundation piece for radical drag racing turbo systems including Radial vs The World and X275 competition. This is the bare cartridge — supplied without a turbine housing — giving engine builders the flexibility to pair it with the exact housing configuration their combination demands. For shops building no-compromise, ball-bearing G-Series turbo systems, this is the core that starts the build.

Performance & Application
The G55-1950 88mm Supercore is engineered for extreme horsepower applications where boost response and top-end flow both matter. The newly engineered inconel turbine wheel and larger turbine exducer deliver a significant flow increase over the previous GTX Gen II design, while the one-piece aluminum center housing reduces overall core weight and improves rotor dynamics through its dual ceramic ball bearing cartridge. This combination allows the G55-1950 to deliver amazing boost response while still supporting nearly 3000 horsepower, making it a purpose-built solution for drag racing platforms that demand both instant spool and massive top-end capacity. Because the core ships without a turbine housing, builders can select the turbine housing configuration that best matches their manifold and backpressure targets.
