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. So with some work, I've collected some baseline 3.6 dyno charts and plotted them out together.
- 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.
- Some plots don't look accurate below certain RPMs, and should probably be ignored
- not all dynos measure power equally
- automobile-catalog.com (Calculated)
- Mishimoto (Dynojet)
- K&N (Superflow)
- AFE (Dynojet)
- Superchips (SuperFlow)
- Ace Engineering (Dynojet)
- Ignored the computer generated data from automobile-catalog.com
- Ignored the unrealistically steep sections at the beginning & ends of some of the pulls (ExtremeTerrain.com's & K&N)
- Smoothed out minor bumps & dips from where certain data starts & stops
