Garrett G-Series G47 Turbochargers

In the chart below you can see the specs for each of the four G-Series G47 supercores. There are three compressor inducer sizes: 76mm | 80mm | 88mm and two compressor exducer sizes: 109mm | 120mm. Each one has its own flywheel horsepower range and the peak horsepower is used to distinguish the supercore from the others.

The G47 turbine wheel supports 2.5L – 10.0L engine displacements. The inconel turbine wheel has a 93mm inducer and an 88mm exducer making it a 90 trim wheel. All of the G-Series G47 turbochargers use the same turbine wheel which means only the G47 turbine housings can be used on these supercores. This also allows enthusiasts to swap supercores if more or less power is needed or if class spec racing called for specific compressor sizes.

G47 Turbine Flow

G-Series turbine aero and flow is one of the most notable features for G-Series turbochargers. The G47 turbine wheel flows up to 20% more exhaust volume than the GTX47 wheel. The turbine wheel will provide up to 9% quicker spool (estimated by flow, efficiency, and inertia). The exhaust flow chart below shows the flow range for each of the four A/R and the dashed lines are comparisons from the GTX47 test data. G47 turbine housings are cast from stainless steel, with T6 inlet flanges and V-band outlet flanges.

Specifications

  • Outline interchangeable with GTX Gen II turbos
  • Supports up to 1650 flywheel horsepower
  • 80mm | comp ind | 109mm comp exd
  • High flow, high efficiency GTX Gen II comp aero
  • G-Series turbine wheel aero increases performance compared to GTX47 Gen II
  • Flow: up to 20% more
  • Spool: up to +9% (estimated by flow, efficiency, and inertia)
  • One-piece lightweight aluminum center hsg/backplate
  • Outlet length on T6 turbine hsg reduced 17mm compared to GTX to optimize weight reduction

Compatibility

  • Universal Part
