This graph shows torsional test data collected for 38" driveshafts. The horizontal axis is displacement or amount of twist in degrees and the vertical axis is the amount of torque in lb x ft. Each colored line represents a different driveshaft and each part was tested to failure. The point where the curve starts is actualy where the driveshaft starts to yiled or take a permanent "set" or twist. Ifthe part war removed and checked anywhere in the curved area, the end yokes would be twisted out of phase. This is especially apparent for steel or aluminum. This testing shows that QA1's carbon fiber driveshafts are far stronger than the aluminum, steel and other competitors carbon driveshafts.
Including U-Joints, QA1's driveshaft also weights almost a pound less (7.4 lbs) than the competition's next strongest carbon fiber driveshaft (8.3 lbs)
A QA1 carbon fiber drivesahft accelerates faster than a steel or aluminum driveshaft due to its lighter weight and lower inertia. In this test, using 55" long driveshafts approximately 3.125" in diameter, the steel driveshaft (blue line) weighed 7 lbs with a wall thickness of 0.125". In contrast, the QA1 driveshaft (red line) weighed less than 6.5 lbs, even with a wall thickness of 0.110". The lighter QA1 driveshaft was capable of handling over twice as much torque as the steel or aluminum driveshaft
