I was at Roebling Road last weekend and put the car on a mobile dyno (Dynojet). The car was running well, but the dyno chart (attached) showed an odd data curve for the torque. The torque line shows numerous spikes.
We ran the car two separate times, 2 hours apart, on the same day, and the same odd spikes in the torque curve were present. This was the only one of 10+ cars that showed this pattern. (eliminating the idea of a bad connection on my runs or faulty pickup line.)
The chart vs. speed:
Also, when the charts were run for Torque and HP vs. RPM the curves were ‘broken’.
Any suggestions as to the cause of the odd charts and/or remedy for this?
