G55-2900 106mm Super Core, G55 Turbo without turbine housing. P/N: 880547-5022S
Garrett G55 turbochargers are engineered for extreme horsepower applications like Radial vs The World and
X275 Drag Racing. A new high-flowing inconel turbine wheel and a one-piece aluminum center housing are the
two major features that differentiate the G55 from its predecessor.
Turbine Stage: The newly engineered turbine wheel with optimized G Series aerodynamics increases flow up
to 15% more (Compared to GTX Gen II, see graph below). Larger 106mm turbine exducer (+4mm compared to GTX55). G55 is offered with two stainless steel V-band turbine housings in 1.24 A/R and 1.40 A/R. The open T6 turbine housing is also available in 4 different A/R sizes: 1.00, 1.12, 1.24, and 1.40.
Center Housing: One-piece aluminum center housing reduces supercore weight. The center housing is air
cooled, features a 16mm dual ceramic ball bearing for premium rotor dynamics, and retains the oil inlet and
outlet specifications from previous GTX designs.
Compressor Stage: Garrett G55 compressor stages are offered in 85mm, 88mm, 91mm, 94mm, 98mm, 102mm, and 106mm
inducer sizes each with their own horsepower ratings indicated in the model name.
Supports nearly 3000 horsepower with amazing boost response
