I have been geeking out on my best friend's 2016 mustang. He's got an OBD2 port bluetooth scanner that can datalog using his phone in real time.
I wrote some script in python and R to try and calculate HP & Torque. Unfortunately, the numbers I'm getting are considerably lower than I expected. The Mustang GT with PowerPack3 should be making ~430 rwhp. In the graph below, the red line is RPM, Blue is Power. I calculated the power based on the weight, velocity, and rate of acceleration. Happy to get into the formulas if you want. It's slightly smoothed (averaged data over 0.2 seconds). Each recorded point is ~0.036 seconds.
Anyways, 4th gear looks really weak at ~300 rwhp. We'd kind of expect to see more numbers like what we see in 2nd gear. I was just wondering if anyone here has experience comparing what they see on the dyno, to what they're getting from datalogs? Is it usually significantly lower in the real world than on the dyno?
