whp stands for Wheel horsepower, an engineering unit abbreviation.
Power measured at the driven wheels on a chassis dynamometer, after transmission and drivetrain losses. Tuners and drag racers quote whp because it reflects what actually reaches the road.
Example: After the tune and cold-air intake, the car made 412 whp on the dyno.
Usage notes
Wheel figures usually run 10 to 20 percent below the manufacturer's crank rating, with all-wheel-drive cars typically losing more. Different dyno brands give different readings for the same car, so comparisons are most reliable on the same machine.
