Anyone can try it, the link is here

The disclaimer does say it is a guesstimate, but the calculations must have been derived from something tangible

When a car is run on a dyno, the dyno calculates the losses of the car on the rundown, far more accurate than a guessing calculator. That calculator classes a 5 speed automatic as modern and 3 speed automatic as typical, I wouldn't have thought their values would be accurate for more modern cars.
I have 2 dyno figures, a car that had the 160 map which produced 146.5bhp and 266.1lbft of torque. Like I said, better than stock.
I then mapped it myself and the same car on the same dyno produced 160.2bhp and 317.7lbft of torque.
