G Series G55 turbochargers feature the latest innovations in turbocharger technology. Advanced compressor and turbine aero offer a range of high horsepower performance boosting solutions for 3.0L – 12.0L engine platforms. 85mm, 88mm, 91mm, 94mm, 98mm, 102mm, 106mm compressor inducer sizes produce up to 2900 horsepower for today’s top drag race teams.

The newly engineered turbine wheel with optimized G Series aerodynamics increases flow up to 15% (Compared to GTX Gen II, see graph below). The large 90 trim turbine stage measures 112mm at the inducer and 106mm at the exducer. G55 is offered with stainless steel turbine housings in:
V-Band Inlet: 1.24 A/R, 1.40 A/R
T6 Inlet: 1.00 A/R, 1.12 A/R, and 1.24 A/R, 1.40 A/R

One-piece aluminum center housing reduces supercore weight. The center housing is air cooled, features a 16mm ceramic dual ball bearing for premium rotor dynamics, and retains the oil inlet and outlet specifications from previous GTX designs.

Garrett G55 compressor stages are offered in 85m, 88mm, 91mm, 94mm, 98mm, 102mm, and 106mm inducer sizes each with their own horsepower ratings indicated in the model name.

WARNING: Maximum allowable turbocharger speed is 84krpm. The use of this product above max turbocharger speed is at the owner’s risk, and can result in damage and premature failure. To protect the turbocharger from overspeed when operating, a speed sensor can be installed into the compressor housing to monitor shaft speed. Sensors sold separately. 

Performance results of this product are highly dependent upon your vehicle’s modifications and tuning/calibration. The horsepower numbers represented above are calculated based strictly on choke flow of the compressor map (total turbo capability), which represents the potential flywheel horsepower.
