CHASSIS DYNO SERVICE

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!

Here we have a 911 RSR type race car prepared for Vintage and club racing.
We built the car with a 3.8L “RSR” spec engine, it has our Twin plug ignition system and 50mm PMO carburetors. We put in some real dyno time getting this car dialed in, from venture changes, cam shaft timing, emulsion tubes, exhaust tip reducers, we got it running like a top. This engine makes a very flat torque curve from 3,300 rpm to 7,200 rpm, and we attained our peek Hp power at 7,600 rpm. This is great for a really drivable car that has some racing longevity. I know that I had a great time in the 2 track sessions I was able to drive the car !!! |

This was our Motec tuning session of the 917 LMK with 3.8L RS spec engine power plant. We first started with a game plan & outlined our needs. We creating a complete Motec engine & chassis program on paper for our car & application uses. We then wrote the program in V3 (Motec software). Once the car was fitted with the engine and all the ancillary items like fuel, oil, and Motec M600 ecu system we built the wire harness. This is such a crucial element of any car & electronic system in a car. We were then able to download our program, run a quick test sweep of all input & all output functions, check Lambda’s etc..
We fire the engine immediately, and within 5 minutes during our initial cam break in we have checked and set “CRiP”. The CRank index Position is perhaps the most important timing value in the ECU. The CRiP tells the ECU where the engine is in relation to TDC Cylinder #1. The CRiP is defined as the distance in crankshaft degrees, between the reference tooth when it is aligned with the crankshaft position sensor, and Top Dead Center Compression Number 1. We were only 5 deg off, Not bad !!! After adjusting a few fuel table adjustments, the car is running smooth and tight just slightly rich overall for break in precautions! We have now set the 917 on our chassis dyno for fine tuning & data logging. Our DynoJet XLC 224 dyno affords us the ability to use the eddy current absorber to run the car under numerous load levels “Whatever we choose”. We are able to fine tune the car & set our compensation tables to adapt to the altitudes & temperatures to come. Look for PATRICK MOTORSPORTS and this 917 LMK at a P.C.A. or Vintage event soon ! |
