Calculate the horsepower of a car with 375 lb. ft. of torque

running at 6400 rpms.

A mechanic uses a dynamometer to simulate an auto mobile

being driven over a mountain pass at 8325 feet in altitude.

The engine is rated at 255 hp at 5200 rpm. What is the loss

in horsepower due to elevation? What would be the Final

HP?

Let’s assume that a car boasts 250 horsepower. When the

engine is running at a speed of 4000 rpms, what should the

torque be?
