anyone ever tested a lightweight pulley on a dyno before and after to see what sort of increases you get?

not a power increase as such,but reducing the mass thats turned by the engine will reduce the effort needed and make the engine slightly free-er revving...would think it would need a lot more tha the pully to be changed to be noticable though,flywheel lightened etc

at idle with wipers/ aircon/headunit/lights on etc etc

my pulley does not charge the alternator, i can blip the throttle and see the lights go brighter, and the wipers move faster

sometimes the powersteering can go a bit funny if your turning with low throttle/low rpm`s
