The longest race ever attempted by the IPG Race Team was a huge success. 6 Hours of road racing takes a toll on the car, drivers and crew but the IPG Team managed to run the entire race and actually finished in great position. The event was the annual PBOC Winterfest 6 Hour Enduro at Sebring Intl Raceway. (January 12th, 2012) A tough qualifying session put the team in the back of the pack in 42nd place to begin the race. But endurance racing isn't always about where you start, it is about consistency and reliability. Drivers Louis Murphy, Russell...

Racing Season is Back !!! The IPG Race Team is headed to Sebring Intl Raceway January 11th-15th, 2012 for the Annual PBOC Winterfest Event. The week starts off with a qualifying session Wednesday night in preparation for the 6 Hour Enduro that the team will be competing in Thursday night. Fielding 3 drivers for the event (Louis Murphy, Russell McMullen and Richy Gonzalez) the team expects to be competitive and keeps the main goal of just finishing the race. The car being raced is the IPG ITA Acura Integra. The car will basically run in the same ITA trim that...

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 –...
