Garrett Intercoolers - Cooler by Design

Garrett intercoolers have a long history with some of the premier names in the performance car industry - Roush, Saleen, Mercedes-Benz AMG, Ford SVT, GM, and McLaren have all turned to Garrett to intercool their hottest models.

Garrett now offers this expertise and quality in a full range of intercool cores. From air-to-air cores sized for tightly-packed sport compact cars to air-to-water cores capable of supporting 1000+ hp, we can provide optimum performance for nearly any application.

Garrett intercoolers also offer superior fatigue protection for the high boost pressures and temperatures of today's extreme engines. They are constructed of high strength brazen aluminum alloys with advanced tube and fin designs to ensure greater heat transfer effectiveness and durability.

Turbochargers

The Garrett ball bearing turbo featuring GT wheel design

GT Basics/Nomenclature | Small | Medium | Large

Proven performance

Garrett's ball bearing cartridge has proven its worth in the highest level of motorsports where it has been the bearing system of choice in CART FEDEX ChampCar Series, 24 Hours of Le Mans, Pikes Peak International Hill Climb, World Rally Championship, and most recently Drag Racing. These premier racing customers demand no less than the best in durability, reliability, and power on demand. One key contributor to this performance lies in the ball bearing cartridge where it is, by design, surrounded by a thin filmof oil. The oil film damps out destructive vibrations that would otherwise compromise turbo durability.

A clear demonstration of the inherent superiority of Garrett's ball bearing design is in the launch of a turbocharged drag race car. The two-step rev limiters used to build boost on the line expose the turbo to the harshest imaginable conditions of pressure spikes and scorching temperatures. Where lesser turbos often fail catastrophically, Garrett ball bearing turbos regularly shrug off these brutal conditions time after time. In fact, many drag racers running Garrett ball bearing turbos have not needed to rebuild or replace their turbos for multiple seasons. Can you say that about your turbo?

Combined with the aerodynamically advanced Garrett GT wheel design, Garrett GT ball bearing turbos provide improved drivability and power on demand.

GT Basics / Nomenclature

Today, Garrett has a wider selection of GT-series turbos available than ever before. As a result of this, please note that we have made a subtle modification to the GT nomenclature.

In our product catalog, all offerings are grouped according to their turbine wheel frame size. The frame size of a turbo or CHRA is dictated by its turbine wheel inducer diameter . The larger the turbine inducer, the bigger the frame size-- so any turbo in the GT42 family has a larger turbine wheel inducer than those in the GT35 family, and so on.

In the model name of each turbo or CHRA, you'll also notice two digits after the frame size. These two digits refer to the compressor exducer diameter, as measured in millimeters.

Let's use the GT4294 as an example. This unit has a GT42 frame size turbine coupled to a 94mm (exducer diameter) compressor wheel.

If there's an "R" on the end of a model name, this means the unit is ball bearing. So, a GT4294 is not ball bearing; whereas a GT4294R is ball bearing.

The biggest change related to the nomenclature is this: units which utilize a 53mm turbine wheel (as measured at the inducer) are now referred to as "GT25" frame size, while units employing the slightly larger 53.85mm turbine wheel are now referred to as "GT28" frame size.

For those familiar with our product range, this means that the unit formerly known as "the GT28R" (part number 466541-1) is now in the GT25R family. More specifically, it is now a GT2560R model.

A Guide To Garrett’s "GT" Model Numbers

GTxxyyzz:

  • Positions "xx" refers to the frame size of the turbine wheel inducer.
    • For example the "GT28" in "GT2860RS" refers to its turbine wheel frame size family. All GT28 units use a turbine wheel with 53.85mm inducer diameter
    • As a rule of thumb, the larger the number, the larger the turbine wheel.
  • Positions "yy" designate the compressor wheel exducer (major) diameter in millimeters
    • The "60" in the GT2860RS example above has a 60mm compressor wheel exducer diameter.
    • Note: Wheel sizes 100mm and over omit the "1" (hundreds digit)
    • Example: the 02 in a GT4202 refers to its 102mm compressor wheel exducer diameter
  • Positions "zz" may be used to designate special features of a particular turbocharger where applicable
    • Example: GT2860RS
    • "R" = this is a Ball Bearing unit
    • "S" = used for units which require some differentiation from units in the same family
      Compare a GT2860R to a GT2860RS. While both are ball bearing and externally similar, the GT2860RS is better suited for higher-flow applications than the GT2860R. In this case, the S reflects the higher-flowing nature of the GT2860RS

What is the Inducer?
Looking at a compressor wheel, the inducer is the "minor" diameter. For a turbine wheel, the inducer is the "major" diameter. The inducer, in either case, is where flow enters the wheel

What is the Exducer?
Looking at a compressor wheel, the exducer is the "major" diameter. For a turbine wheel, the exducer is the "minor" diameter. The exducer, in either case, is where flow exits the wheel.

Compressor wheel exducer diameter is incorporated into Garrett GT-series nomenclature: The "60" in the GT2860RS for example, has a 60mm compressor wheel exducer diameter.

This system allows you to keep the same displacement, bore & stroke, and compression ratio as the stock set-up. With a minimal weight gain of just 20lbs, this kit will generate nearly double the horsepower! With the estimated 12-14 psi of boost, an increase in carburetor throttle size is required - from a 35.5mm throttle body to a fuel injected system with a 40mm throttle body to handle the increased boost. This is some major power you will feel in the seat of your pants!
