GARRETT G25-660 TURBOCHARGER 0.72 A/R V-BAND / V-BAND
The newest generation of Garrett turbocharger / 871389-5010S
A real evolution of the GTX turbos
Garrett now launches a new line of turbochargers that are close to the BorgWarner EFR turbochargers - the G25 series. The special features are: - Forged and machined compressor wheel of the latest generation with up to 15% more flow (than the GTX series, Gen II series) on 60mm wheels and even 30% more flow on 67mm compressor wheels - Highflow compressor housing with optional connection for the speed sensor - Turbine wheel made of Mar-M (up to 1050° C resistant) with 15 to 20% more flow - Stainless steel turbine housing resistant up to 1050° C - Exhaust housings with V-band inlet and V-band outlet - CHRA with V-band to be twisted individually - Double ceramic ball bearings - 4 water connection ports - Double seal on the piston rings - Right and left rotating turbochargers available. Power range: Up to 660HP Engine capacity: 1,4 up to 3,0l Notice: Rotation is clockwise! Turbo inlet flange: V-Band Turbo outlet flange (downpipe flange): V-Band Compressor facts: Inlet: 54.00mm Outlet: 67.00mm Trim: 65 A/R Valuet: 0.70 Turbine facts: Inlet: 54.00mm Outlet: 49.00mm Trim: 84 A/R value: 0,72 Right and left rotation direction: The absolute novelty of the GTX Gen II turbocharger was naturally adopted in the G-Series. The G-Turbos are also available as reverse rotating turbochargers.
GENERAL GARRETT G SERIES TURBOCHARGER DESCRIPTION
Compressor: All G compressor wheels are CFD designed, forged and milled from special, high strength aluminum alloys. The new G-Series compressor wheels achieve 15% more airflow on 60mm wheels and 30% more on the 67mm wheels 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, 15-20% 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. Currently the turbine housings are only available with V-band flanges and without wastegate. In the future, all other flange patterns and internal wastegate options will also be available here.
