Due to the fact that a dyno measures torque. It then uses a formula to calculate the horsepower, this is done by multiplying torque by rpm/5,252 hence the 5252rpm figure that people quote. However as the torque and horsepower are usually different at each RPM, the scale itself is altered to fit them both into a viewable window. It also measures "reverse" torque on rundown, ie transmission drag, and compensates for this.GuidoK wrote: ↑Thu Oct 05, 2017 5:00 pmWhy should the lines on that dynosheet cross at 5252rpm?

And if we are being pedantic, the figure is 5,252
