Starting a BB Duster project

Horsepower is horsepower no matter what motor it’s on. I don’t believe a fan is going to draw anywhere near 30 hp, but whatever it draws it would be the same on whatever engine you have it on.

Not quite. Torque is the determining factor on engine load, not hp (even though yes, they're closely related). That's why a truck with 300hp would probably have no trouble towing a 3-ton trailer, when you definitely wouldnt try to tow that trailer with a 300hp civic.

An engine with higher torque is always going to handle more load than an engine with lower torque but comparable hp.
