7+7 Billet Compressor Wheel Design Specifically Named, Not Just A "High-Flow Turbo"

Many racing turbochargers describe themselves as "high-flow" without naming the actual compressor wheel engineering behind that claim. Garrett names this specifically for the GXR57-98.

Compressor wheel design specifically named as 7+7 billet configuration

The turbo specifically uses an advanced 7+7 fully-machined billet compressor wheel, combining seven primary blades and seven splitter blades — a concrete, named blade configuration, rather than an unspecified "advanced compressor" claim with no stated design.

Compressor flow increase specifically measured at up to 40%

The GXR55/57-98 configuration specifically delivers up to +40% compressor flow compared to the G55-1950 reference turbo — a concrete, measurable flow improvement with a named comparison point, rather than an unspecified "increased airflow" claim.

Horsepower rating specifically stated at up to 2900

The GXR57-98 is specifically rated up to 2900 horsepower based on compressor flow testing — a concrete, measurable power ceiling, rather than an unspecified "extreme horsepower capability" claim.

Turbine wheel dimensions specifically measured in millimetres

The turbo specifically features a 118mm inducer and 112mm exducer turbine wheel — concrete, precise dimensions, rather than an unspecified "large turbine" claim.

Center housing material specifically named as one-piece aluminum

The turbo specifically uses a one-piece aluminum center housing and backplate to reduce overall weight — a concrete, named material and construction approach, rather than an unspecified "lightweight design" claim.

Compressor sizing specifically stated in millimetres

The GXR57-98 specifically measures 98.9mm at the compressor inducer and 149mm at the compressor exducer — concrete, precise compressor dimensions, rather than an unspecified "large compressor" claim.

Intended application specifically named for racing classes with inducer rules

The turbo is specifically designed for drag race classes and classes with compressor inducer rules — a concrete, named use case, rather than an unspecified "competition-grade" claim with no stated regulatory context.

In Summary

Product: G-XRace GXR57-98 Supercore (934174-5006S)
Brand: Garrett
Horsepower rating: Up to 2900 HP
Compressor flow increase: Up to +40%
Compressor wheel: 7+7 billet design
Turbine: 118mm inducer / 112mm exducer

Who This Turbo Suits

This turbo suits serious drag racers who want a specifically named compressor wheel design, like the 7+7 billet configuration, rather than an unspecified "high-flow turbo" claim with no stated engineering detail. Its named compatibility with drag race classes that have compressor inducer rules also makes it a practical choice for racers competing in regulated classes who need to confirm their turbo meets specific size requirements. \\Shop Garrett G-XRace GXR57-98 —
