You'll not be adding to much in the way of power just by changing to lightweight pullys its not as simple as that. Along with the usual under bonnet mods to get the best from pully mods light weight clutch flywheel comes into the equation. Combine this little lot and there be a torque increase and engine will spool up a bit quicker.
Winter last i played with the under bonnet power of my STi2 and purely because i was there (Cam belt change) i replaced the om steel pullys for Roger Clark racing light weight alloy pullys. Clutch still has the om flywheel. What sort of pwr gains from those pullys? Very minimal i would think. Looks smart though.
