Courtesy of www.TurbobyGarrett.com Getting a little more complex here. Trim is a common term used when talking about or describing turbochargers. For example, you may hear someone say "I have a GT2871R 56 Trim turbocharger". What is 'Trim?' Trim is a term to express the relationship between the inducer* and exducer* of both turbine and compressor wheels. More accurately, it is an area ratio. * The inducer diameter is defined as the diameter where the air enters the wheel, whereas the exducer diameter is defined as the diameter where the air exits the wheel. Based on aerodynamics and air entry...

Courtesy of www.TurbobyGarrett.com On the exhaust side, a Wastegate provides us a means to control the boost pressure of the engine. Some commercial diesel applications do not use Wastegates at all. This type of system is called a free-floating turbocharger. However, the vast majority of gasoline performance applications require a Wastegate. There are two (2) configurations of Wastegates, internal or external. Both internal and external Wastegates provide a means to bypass exhaust flow from the turbine wheel. Bypassing this energy (e.g. exhaust flow) reduces the power driving the turbine wheel to match the power required for a given boost level....

The journal bearing has long been the brawn of the turbocharger, however a ball-bearing cartridge is now an affordable technology advancement that provides significant performance improvements to the turbocharger. Ball bearing innovation began as a result of work with the Garrett Motorsports group for several racing series where it received the term the ‘cartridge ball bearing’. The cartridge is a single sleeve system that contains a set of angular contact ball bearings on either end, whereas the traditional bearing system contains a set of journal bearings and a thrust bearing Journal Bearings Ball Bearings Turbo Response –...

HKS has released a GTII Series turbocharger upgrade for the Mitsubishi Evolution X, the GTII 7460. The special cast turbine and compressor housings of the HKS GTII 7460 allows it to be a true bolt-on upgrade for the Mitsubishi Evolution X by utilizing the OEM exhaust manifold. The HKS GTII 7460 is a twin scroll turbocharger allowing a shorter and straighter exhaust path to the turbine wheel while delivering the benefits of less restriction and increased boost response. This allows full spool and stable boost pressure throughout the RPM range. Intake and exhaust port designs optimize the flow area to...
