Courtesy of www.TurbobyGarrett.com. 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 –...

We are big fans of the Garrett Turbochargers. Over the years they continue to offer a great product with great value. Reliability is very important to us when it comes to the products we sell and use and the Garrett Turbo Product line are some of the most reliable turbochargers on the market. This excerpt is taken from the www.TurbobyGarrett.com website -- they are a wealth of information and we will do what we can to get the knowledge to our customers. http://www.turbobygarrett.com/turbobygarrett/basic How a Turbo System Works Engine power is proportional to the amount of air and fuel that...

Since we started racing the ITA Integra we have consistently had braking issues. A cooling setup was on the to do list for quite some time and we finally got around to getting a nice setup done on it. All design and fabrication was done by Russell McMullen for us who also happens to be co-driving the car. A system was designed to use existing mounting points as much as possible to funnel the air directly into the center of the rotor. All mocked up on a spindle on a workbench here is what was came up with. Here are...

Recognizing Common Failures There are six types of metallurgical failures that affect fasteners. Each type has unique identifying physical characteristics. The following examples are designed to be used like a spark plug reading chart to help analyze fastener failures. While few of us have access to sophisticated analysis equipment, a standard Bausch and Lomb three lens magnifying glass will generally show 98% of what we want to see. Several of the photos below have been taken utilizing a Scanning Electron Microscope (SEM) and are presented to simply illustrate typical grain configurations after failure. 1. Typical Tensile Overload In a tensile...

This is information that you can never find when you need it so here is a table for the ARP Head Studs, Main Studs, and Rod Bolts Torque Specifcations and Stretch Specs. Listed here are the general torque recommendations for most ARP fasteners. Recommended torque is equal 75% of the fastener’s yield strength. Simply read down to the correct fastener size, then across to find the torque value for your application. Always lubricate the fasteners prior to applying torque to ensure accurate readings. NOTE: The torque values represented here are intended to be for general information only, not for specific...
