Example-An engine that produces 300 pound-feet of torque at 4,000 rpm produces 228 horsepower at 4,000 rpm. This is based on the formula that horsepower is equal to torque multiplied by engine speed and that sum divided by 5,252. The constant, 5,252, is used to convert the rpm for torque and horsepower into rpm's.
then how come all cars dont have the exact same hp to tq ratio? my car has 290 tq and 205 hp, yet the si has 139 and 197.. seems that "constant" is not a constant at all.. btw im a noob to this stuff
