QUOTE(ykc8 @ Dec 23 2007, 11:09 PM) Underdrive pully is made smaller than the original pulley in terms of size...When it is made by aluminium and underdrived, it helps to reduce the workload of your engine, hence increase horsepower and save fuel. Faster pick-up can be gained instantly, and maximum horsepower gained across 3000-3500rpm. its lighten crankpulley bro.Lighter will result in better engine response coz the pulley is lighter but bear in mind the standard crank pulley has built in damper does the lighten pulley has it.
