What he means is dyno of the same brand that use the same equations to calculate HP and Torque and use the same resistance in their wheel will have same results. So if you want to compare numbers and brag to your friends you better be sure both numbers are from same brand dyno.
As for accuracy of the measurement on each machine to the actual HP and torque of the motor I'd say none are right. Because wheel horsepower is an inaccurate measurement on its own with different cars having unique rotational mass and resistance in the drivetrain. Brake Hirsepower is the power of the motor itself without drivetrain which is better measurement.
And if 2 300 whp cars race there's the new factor of vehicle weight and wind resistance!!!! Nobody cares about HP. It's how fast you get from A to B with everything factored.
DYNO IS MEANT FOR TUNING AND DIAGNOSIS!!!!!!!! Not to brag about you "power". Also used for emissions testing lol.
We clear now?
