They do not provide ANY additional horsepower (this is
not debatable unless the pulleys are UNDERdrive style)
They DO reduce rotational inertia, but by about .000001 %
They are likely to allow harmful engine harmonics to wreak havoc on your main bearings.
If you are changing to LWCP to reduce the overall weight of the car, then carry on. (but if you still have a spare tire and interior, you are focusing on the wrong components)
example: The highest reported hp in NA application in this car has the fluidampr front pulley which is
heavier than stock.
