It's a percentage.
It affects both torque and horsepower at about the same rate.

Torque and power are directly related by rpm, as per the equation above. For a given rpm, any change in one will be exactly reflected in the other percentage-wise.

6-cylinder or more, yes.
I guess you're never seen numbers off a Honda VTEC engine, huh?
B18C - 180hp, about 120lb-ft of torque, at flywheel
