No - the engine will be producing the exact same horsepower as before. Hopefully more of it will be reaching the rear wheels.

No. You will be lucky if you see 2 hp difference.

I highly doubt it. The main benefit to aftermarket pulleys is to increase contact with the water pump pulley when the airpump is removed.
