Near 5252 to be exact, because of how torque and horsepower are related. Horsepower is a function of torque and RPMs when calculated, P = (T x w) / 5252.

P = Horses, T = Torque in lb-ft, w = Rotations in RPM. So for example an estimate for Horsepower at peak torque on a car with a peak torque of 200lb-ft at 3400rpm should be 129 or so. If the car hits peak HP at 6800rpm and the engine's producing more like 140lb-ft of torque, it's producing around 180hp. See kids? Show this to your parents when they say you can't learn anything off the internet.
