Garrett GXR38-64 (CH Hose) Turbocharger

Developed for Drag Racing and Motorsport Applications

XBoost technology for high boost levels and maximum performance, rated for up to 1100 HP

Developed for Regulated Racing Classes
The Garrett G-XRace GXR38-64 was specifically developed for XWorld Drag Racing and racing classes with a maximum permitted compressor wheel inducer diameter of 64.9 mm. This allows the turbocharger to deliver high performance potential while complying with the technical requirements of the respective racing classes. Always verify the applicable class and motorsport regulations before purchasing and using the turbocharger. The G-XRace also provides a direct upgrade path from the GXR45-73 and features compatible overall dimensions for XFWD class applications.

The optimized compressor aerodynamics enable higher pressure ratios and support increased boost levels. At the same time, high flow efficiency delivers cooler, denser charge air, helping to maximize the engine's performance potential.

The GXR38-64 is suitable for engines with a displacement of 2.0 to 5.5 liters. The high-temperature-resistant Inconel turbine wheel features a 66 mm exducer. Depending on the application, stainless steel turbine housings are available with V-Band or T4 Twin-Scroll inlets and various A/R ratios.

• High-flow compressor housing with optional turbo speed sensor port
• Inconel turbine wheel with 74% increased efficiency
• Stainless steel turbine housing resistant to temperatures up to 1050°C

The following Garrett components can be used for turbo speed monitoring:

• Garrett G-Smart Module / App - PN 923586-0003
• Garrett Speed Sensor Kit Street with gauge - PN 781328-0003
• Garrett Speed Sensor Kit Pro without gauge - PN 781328-0004

Right and left rotation direction:
The absolute novelty of the GTX Gen II turbocharger was naturally adopted in the Gen II series. The G-Turbos are also available as reverse rotating turbochargers.

GENERAL GARRETT G SERIES TURBOCHARGER DESCRIPTION

Compressor Wheels:
All G compressor wheels are CFD designed, forged and milled from special, high strength aluminum alloys. The new G-Series compressor wheels achieve up to 30% more flow than the GTX Gen II compressor wheels.

Compressor housing:
The new aero-optimized high-flow compressor housings with integrated mounting for optional speed measuring sensors are adapted to the new G-series compressor wheels. The generation I improved recirculation systems have been adopted in the G-Series and significantly extend the operating range of the compressor by shifting the surge line.

Cartridge:
All Garrett G CHRA's are equipped with 4-port water cooling. So 2 connections can be selected on each side. This considerably facilitates the installation of the water pipes and hoses. And of course the G-Series comes with a double ceramic ball bearing like the Gen II. New is the double piston ring seal on both sides.

Turbine:
The new tubrine wheels are made of the high-performance material Mar-M. This material withstands exhaust gas temperatures up to 1050° C. Here too, 75% more exhaust gas flow was achieved with the same wheel dimensions compared to the GTX turbocharger.

Turbine housing:
The exhaust housings are cast from a special stainless steel alloy which also withstands up to 1050° C.

If this turbocharger is not marked as stock ed, it may still be the case that we have the individual components in stock and can assemble the turbocharger for you. Please call us or send an email to check if the turbocharger may be available from stock . You can also ask if alternatively shorter delivery times than specified are possible, as this often depends on the right time of the order.
