Speed Parts Preview: 2,500 HP GARRETT TURBO


Honeywell today announced the release of the Honeywell Garrett GTX 5533R Gen II turbocharger, its most powerful turbo ever produced. The GTX 5533R Gen II turbocharger features brand new and highly advanced GTX compressor garrett_gtx5533r_productwheel technology in a large frame turbo producing 1,000 to 2,500 horsepower.

The GTX5533R Gen II is designed for race classes with specific compressor inlet diameter rules, and for enthusiasts looking to make extreme horsepower. The GTX5533R is class legal in inlet restricted drag racing classes including NHRA Pro Mod, NMCA Drag Radial, and PDRA Pro Boost.

Furthermore, the GTX 5533R turbocharger features Honeywell’s Gen II forged CNC machined compressor wheel. Starting with a high strength, near net shape, forged blank, Honeywell CNC machines the blade profiles to make the thinnest blades possible without sacrificing strength. This results in the strongest, lowest inertia, fastest spooling and most aerodynamically efficient compressor wheels in the market.

GTX Gen II compressor wheels are available in 85mm, 88mm, 91mm, 94mm, and 98mm inducer diameters to help you match your compressor to your desired power output or class rules. The improved Gen II compressor wheel lives in a revised high flow compressor housing with a fully machined inlet, V-band outlet, and integrated speed sensor and pressure signal ports. The integrated speed sensor port accepts Garrett’s speed sensor kit. (Sold separately)

A fully-machined ported shroud features an improved ported design for surge resistance allowing air to bypass the compressor wheel when the engine’s flow rate is lower than what the compressor wants to flow, reducing surge during these times.

The compressor housing also has a new sleeker profile and features a lightweight billet aluminum backplate which is lighter than the previous steel version. This saves four pounds!

The GTX5533R uses Garrett® patented dual ceramic ball bearing center section. The dual ball bearings reduce friction resulting in much faster spool and also require less oil than traditional journal bearings, which can help an engine maintain oil pressure.

To further tune the GTX 5533R’s response and power output there are both SFI certified and non SFI turbine housings ranging from 1.00 – 1.78 A/R so an engine builder can balance flow with response time. These features make the GTX 5533R today’s premier choice for high power applications. Please visit http://turbobygarrett.com for more information.
