540 Dyno Test The screen shot below is of the first run's results, the primary goal of which was to see if the motor would create too much boost for pump gas on the street. The pull created 8lbs of boost bringing the compression up a little high, but this thing will never hook on the street, so it may never see 8 lbs of boost. Just to be safe, another set of pulleys will be ordered. Better to be safe than sorry. Click the picture below for a full size shot of the screen.
Below is page two of the data. This view contains some interesting figures as well. The water temp only rose by 1.5 degrees during the pull and the V.E. or Volumetric Efficiency of the motor is incredible. 100% would be perfect for a naturally aspirated motor, but is not attainable in the real world, so a reading of 144% means that the motor is using the boost created by the blower efficiently. The motor was making just over 12 lbs of boost after 6500 rpm's on this pull.
Below is the exhaust temperature chart from the first pull. Superchargers are known for creating heat on the exhaust side and this chart proves it!! Damn, that's hot!
Here is a shot of pull number two and in the third column, you will see 985.6 HP and in the second, you will see peak torque of 797.7 ft-lbs. Talk about a kick in the ass!!! Can't wait to see this run. Column four shows the Gallons of fuel per hour. This thing uses near 80 gallons per hour running under load. Better get a bigger fuel cell Adam.... Note how steady the oil temp and oil pressure are. The oil pump has a bypass at 68lbs which is why it never exceeded 70. The motor produces peak HP by 6700 and peak torque at 5600; both very usable numbers. The car will be launched at 5000+, so this is perfect. Did I mention that this motor was built for the street and you will see it everywhere! Keep your eyes peeled...
Here's a shot I pulled from the video showing the 12 lbs of boost. Check out the pulley flying in the background. The motor was turning 7000 rpm at this point.
