Corner Balancing: The Last Step in your Suspension Upgrade

Corner Balancing: The Last Step in your Suspension Upgrade You fell in love with driving your Porsche when you purchased it, but over the years and miles the handling began to lose its crisp response as the wear and tear took its toll. Wanting to get that great handling and even more back, you made the decision and upgraded the suspension to competition or sport type coil-over struts/shocks that have adjustable spring height perches like those of the Bilstein PSS9 and PSS10 systems. To make your Porsche’s high performance/competition suspension truly effective in its braking and cornering, there is also another very important step in the process of optimizing your car’s handling; the distribution of the car’s weight on its four tires. This is because the tire that is supporting less weight, when compared to the other three, is likely to be the first tire to lose traction when encountering the constantly changing dynamic forces created through movement and speed ... read more

Servicing the Cayenne Automatic Transmission

Servicing the Cayenne Automatic Transmission We were contacted recently by a PCA club member who asked if it would be possible for him to perform a service on the automatic transmission in his Cayenne. The answer is a qualified yes, it is possible; however, having the required tools and the procedural knowledge for performing this service is critical. After documenting this information, we thought that it might provide an interesting insight for club members as to what is involved in performing this important service for the Cayenne. This is also somewhat indicative of servicing the later model Tiptronic transmission equipped Porsche’s. We recommend you warm up the engine to operating temperature. Drive the vehicle and make sure that the transmission operates properly; shifting correctly in all gears and speeds. Let the car cool down overnight before starting the transmission service. Be prepared to dispose of the fluid and filter properly due to t ... read more

What does it take to wear out a Porsche?

What does it take to wear out a Porsche?

A 24 hour race. The 24 Hours of Le Mans or the U.S. equivalent, the 24 hours of Daytona, are both incredible endurance races where just finishing is a cause for celebration. An intense race like the Daytona 500 takes roughly 3-1/2 hours to complete, however this is a “Walk in the Park” when compared to running a car flat out for 24 hours. Consider that operating a street car under these same conditions would be the equivalent of a lifetime of wear and tear, every mechanical system in the car would be completely used up. Like the wear and tear on the racecar, the people involved are also pushed to the limits. The rules allow for a minimum of 3 drivers per car, some teams will have 4 to 5 drivers per car to complete the 24 hour race. The drivers all take turns at the wheel rotating in one hour driving stints and even double stinting on rare occasion for the driver’s that are in incredible physical condition. When they are not in the car, they are trying to slee ... read more

Porsche Engine Rev Limiter Systems

Porsche Engine Rev Limiting Systems Engine Rev Limiter systems started in the early Porsche 911’s as a mechanical sliding ignition rotor whose sole job was to cut power in the event of an engine RPM over-rev. A section of the ignition rotor would slide outwards driven by centrifugal force depending on the engines RPM speed and would eventually make contact with a ground terminal, shutting the engine off until the engine reached a safe RPM range. The simplicity of the past is now gone and replaced with an extremely accurate electronic control system. The rev limiter for the 9X6’s and 9X7’s utilize a fuel/ignition cut off system operated by the DME (Digital Motor Electronics) controller that engages when the engines RPM reaches a model specific maximum limit. In addition to the current rev-limiter controls, today the DME keeps a record of all engine over-revs. The over-rev capture capability should be checked during a PPI (Pre-Purchase Inspection) be ... read more

Beauty is in the Details

Historically, Porsche’s paint quality has always been world class. However, over time, your car’s paint is exposed to combinations of dust, dirt, tree sap, bird dropping, water, chemicals plus everything else in the air which can take a toll on the quality of the finish. Of course, the painted surface of any car must be cared for to maintain its outstanding finish. Unfortunately, not all Porsche owners keep up with the maintenance of the exterior finish. Reasons differ, but the most common is just not having the time to do it yourself. Today, there are many fixed location and mobile professional detailing services that cater to conscientious car owners that want to preserve their cars fine finish. When choosing a detail service business, it is best to get recommendations from someone you trust, your friends, your mechanic, a high quality paint shop or the local PCA (Porsche Club of America) chapter. It is also important to use companies that utilize methods and p ... read more
