HP would actually stay the same. You are multiplying the torque by 3x, but you are dividing the RPM by 3. Horsepower would stay the same.
200 torque x 6,000 RPM = approx. 228 HP
Now first gear ratio of 3:1
600 torque x 2,000 RPM = approx. 228 HP. It is the exact same horsepower.
If you wanted to get technical you could point out that since there is a slight torque loss from friction the torque would be slightly less than 600 and there would be a slight HP loss.
