Hi, first post
My main hobby is racing bicycle time trials. I'm very involved in the field testing "community" when it come to bicycles, aero drag and rolling resistance. The tool that has made CdA and Crr measurements available to "anyone" is the power meter. With the PM, there is no need for perfectly flat roads, known constant grades, coastdowns etc. Using the PM, a scale, a thermometer, air pressure data and a suitable stretch of "quiet" road you can measure you Crr and CdA with surpricing accuracy, often within 2%.
I have looked around here for any references to car power meters but found nothing. Can anyone point me in the right direction?
I have a ´96 1.6L Corolla and have an idea to put a load cell under one of the two longitudal engine mounts. That way I should be able to measure the "driving torque". Add a speed sensor and a data acquisition system hooked up to a laptop and I got myself a power meter
Anyone done something similar?
