        Is there a specific belt size you should use with this on a 2003 Cobra?

        Is this pulley the same diameter as the stock pulley?

        • Hello! This Professional Products Powerforce Harmonic Damper works for 2v and 4v. It is approximately the same diameter as the stock balancer at 6.8". Only thing is when used on 4 valve applications the accessories (alternator, A/C, etc) will spin 3% slower than stock.

        Whould this harmonic damper work with BBK Underdrive Pulleys (96-Mid 01 GT) Item #56007?

        • The damper will not interfere with any pulleys. It should provide your car with more dependability and precision than any factory damper would give you.

        Can anyone offer advice on how this one compares to the 2001 mustang bullitt damper? I don't want to mix up something since I know the bullitt came under driven and possibly spin something too slow like my water pump. My damper is just at 160k miles and i want to replace it before it starts to go.

        • Hi, This Professional Products Powerforce Harmonic Damper will make accessories spin 3% slower than stock, but since the 2001 Bullitt's alternator pulley and water pump pulley are lager than stock this damper shouldn't cause any problems.

            powerforce damper

            I bought this damper to replace my old aluminum piggyback style underdrive crank pulley after the key slot wore through it give you peace of mind knowing that this pulley is solid and built to last im not afraid to say that this product is better constructed and looks way better than stock can't go wrong with adding it to the list of mods

            Powerforce Performance Damper

            fit perfectly. Timing marks are easy to see. The annoying thing is that you will need a longer serpentine belt . The stock one is too short.
