Garrett G-XRace GXR38-64 64mm CH V-Band Super Core

Garrett G-XRace GXR38-64 V-Band Super Core | 1150 HP Turbo

Maximize race performance with the Garrett G-XRace GXR38-64 V-Band Super Core. Features 64.9mm compressor, V-Band outlet, and XBoost technology for 1150 HP

The Garrett G-XRace GXR38-64 64mm CH V-Band Super Core is a top-tier, race-dedicated turbocharger core designed for high-boost drag racing and competitive motorsport classes like XFWD and XWorld. Rated for up to 1,150 horsepower on engines ranging from 2.0L to 5.5L, this supercore features a class-legal 64.9mm forged aluminum compressor wheel paired with a rigid, leak-proof V-Band compressor housing (CH) outlet for direct welded charge pipe assemblies.

Built around Garrett's advanced XBoost technology, the GXR38-64 handles extreme manifold pressure ratios with exceptional 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 cartridge for instant throttle recovery, and an integrated speed sensor port for advanced racing telemetry.
