If an engine with high horsepower can gear down to increase torque, couldn’t a high-torque engine be geared up to increase horsepower?

Question

Just wondering why, in these discussions, people always say the former and not the latter.

Answer 1

Horsepower is more a measurement of raw power regardless of what combination of speed and torque that is.

High torque can be geared to low torque higher speed.

High speed can be geared to low speed high torque.

Horsepower doesn’t change.
