The chapter had its dyno day today. Thanks to Ivan ** and Doug Levin for arranging it. For us, it was a cool, dry day which helped the results.
I did two runs with my car. Everything was as I usually drive it except we took the air filter out for the runs. ( It was very dirty.) It was a Dynojet Research dynamometer.
Here are the smoothed results ( Smoothing:3 ) for the two runs:
First run: 12:04:03 P.M., 77.92 degrees, 30.14 in-Hg, Humidity: 32%, SAE: 0.98, Max Power= 683.45 RWHP, Max Torque= 609.44 RWTQ.
Second run: 12:10:16 P.M., 78.69 degrees, 30.14 in-Hg, Humidity: 30%, SAE: 0.98, Max Power= 685.47 RWHP, Max Torque+ 615.45 RWTQ.
So, using a 12% driveline loss assumption, the flywheel HP and Torque for the best run was : 778.94/699.37.
For those who do not know the car, here is a full description of the car:
2006 SRTC with Paxton supercharger, competition coupe swing arm oil pan, DC blower tune, cooler thermostat and plugs, MGW/Woodhouse shift mechanism, 2008 transmission, yolk, drive shaft and differential, Racelogic traction control, Corsa catback exhaust, 2008 hood, Eibach springs, Moton Sport shocks - corner balanced with track settings, ACR wheels and tires. Woodhouse Performance engine and transmission mounts. The interior has two changes. The shift bezel is lighter, lower and powder coated satin black to match the wheels. The door grasps are also powder coated satin black to match the wheels. The car was/is the first officially certified Woodhouse Performance Edition Viper. The plenum was autographed by Herb Helbig at CAAP after he inspected the car on the line while it was being built. The Owner's Manual is autographed by Ralph Sjoberg and Dick Winkles.
I am very pleased with the results. To quote Doug: "That's a strong car".
