I've was wondering how all the aftermarket baseline dyno curves compare to each other, and found a neat website that lets you convert images into CSV data www.graphreader.com (also using onlinecamscanner.com to correct the out-of-skew images
stolen borrowed from videos). So with some work, I've collected some baseline 3.0 dyno charts and plotted them out together. If you know of any more, feel free to share.
- automobile-catalog.com provides engine torque that has been estimated by a computer. I'm not sure how they do this, but I found that factoring 85% for drivetrain losses puts it about in the correct spot. Unfortunately the curve doesn't really match all the other data.
- FCA's published figures also match up at around 85% for drivetrain loss
- None of the plots look accurate below 3000 RPM
- not all dynos measure power equally
