Engine blueprinting and build services are available for in-house projects as well as engines freighted in. We employ several full time dedicated specialist service and engine builders. Cleaning, detailing and inspection are the critical first steps in determining what the engine will need. From there we can plan the build and select a variety of options. Options given are often custom tailored to your specific needs and we are extremely selective with the parts we use. Our labor cost is determined by actual labor time. This often works in the customer’s advantage. The typical basic rebuild is approximately 40 hours of time. Our tooling equipment and assembly experience makes us a valuable option for rebuilding and race preparation services. If you are thinking of having your engine rebuilt, please contact us, you will be pleased with the outcome.

We have Industry leading CWT computer balancing equipment. With this we are able to balance you engines and flywheel, pressure plate systems to reduce vibration and increase horse-power and parts life. If you are wondering why balance these components let me give you some information that will get your attention. When GM, Ford and Chrysler produce a typical vehicle they would generally accept a balancing specification of 2.0 ounce-inch tolerance, so what does that mean? The 2.0 ounce-inch tolerance means on a typical crankshaft that has a diameter of 6.0 inches will have 18.95 grams of unbalanced weight residually embedded in the outside edge of the counter weights. When the engine is running at 1000 rpm’s (just above idle), the embedded weight will cause the rotating crank assembly to generate a centrifugal unbalance force of 3.56 pounds. As we increase the RPM’S to 2000 the unbalance force increases to 14.25 pounds, at 4000 RPM it is now 56.5 pounds and at 8000 RPM’S will generate 228 pounds of force. Simply put if the combustion activity of the engine is the source of power then unbalance forces are the dampening or restricting forces that will waste the engines potential output. Elimination of vibrations and possible deformation as a result of the pounding activity is a welcomed benefit. Professional engine builders understand that the unbalance forces change how engine parts interact with each other

We have a state of the art chassis dyno for expert race preparation. We don’t mean run-of-the-mill performance; we’re talking about making your engine’s entire Horsepower curve stronger. Too often during dynamometer testing there is a tendency to focus on flash power peaks. Customers and novice dyno operators do this all the time... mostly because the numbers are higher! You want sustainable power. However, vehicles must accelerate using their entire RPM band.... and even drag engines must produce strong power for more than just a single 1/10 second line on a data points listing! The DE series Air Gap Eddy Current Dynamometers are Designed for testing engines to 966 hp (720 kW). These are low inertia, water-cooled Eddy Current Dynamometers designed to provide our customers with a precise, robust and repeatable alternative to water-brake technology. An Eddy Current Dynamometer produces braking torque using the principle of eddy currents induced on a rotating metallic disk, immersed in a magnetic field. All of our Eddy Current Dynamometers include a strain gauge load cell to provide torque measurement capabilities for precise test and development applications. A variable reluctance (Magnetic Pickup) sensor and 60 tooth gear are provided for sensing speed (rpm). These units are built to last. The rugged design of the power absorbing system ensures a long operating life, even in the most demanding applications and environments. The long life and ruggedness of the product is further enhanced by the nickel plating of critical components in contact with the cooling water. Patrick Motorsports is your Porsche Dyno Service HQ in the Phoenix, Scottsdale, Tempe area!
