Garrett G-XRace GXR38-64 64mm CH Hose Super Core

Garrett G-XRace GXR38-64 Hose Super Core | 1100 HP Turbo

Maximize race performance with the Garrett G-XRace GXR38-64 Hose Super Core. Features 64.9mm compressor, hose outlet, and XBoost technology for 1100 HP setups

The Garrett G-XRace GXR38-64 64mm CH Hose Super Core is a motorsport-dedicated, high-output turbocharger cartridge engineered specifically for regulated drag racing and competitive track classes like XFWD and XWorld. Rated for up to 1,100 horsepower on engines ranging from 2.0L to 5.5L, this supercore features a class-legal 64.9mm forged compressor wheel paired with a traditional hose-connection compressor housing (CH) for silicone coupler plumbing setups.

Built around Garrett's advanced XBoost technology, the GXR38-64 handles extreme manifold pressures and pressure ratios with incredible thermal efficiency. It incorporates a race-proven Inconel turbine wheel designed to withstand continuous exhaust gas temperatures up to 1050°C (1922°F), a dual ceramic ball bearing assembly for immediate transient response, and a fully-machined speed sensor port for precise datalogging.
