Me neither. It reduces parastitic loss. That will free up both Tq and HP. That guy definitly doesn't know what he is talking about when it comes to Underdrive pulley's.

Your local shop rates 62 on the car IQ test.
Do they specialize in tires by any chance?
Run, don't walk to find a new shop.

hp is calculated from torque and rpm, so I don't see how you could lose tq and gain hp at the same rpm point.

Nonsense! If that were true, every race car on the planet would be running around with dampeners as big as wagon wheels!

He's probably recalling his high school physics that since T = F X r, and you are reducing r, T is also reduced. However, the pulley is not producing any torque! It's only along for the ride and is, strictly speaking, only contributing to inertia (yes, we all know it provides harmonic dampening). That's why reducing that moment frees up torque produced by the engine to propel the car. Consequently, rear wheel torque and horsepower increase.

There's always an easy way to tell if someone's giving you a load of BS. When they make some incredulous statement like that, always ask them, "Why?" It's fun to watch the stammering and stuttering.
