HERE`S THE ANSWER TO THE POLL
Warren you didnt have to complicate it. You know what im talking about. Today I changed my 1.8 ratio fan pulley to a 1.3 ratio. When I was waiting for the correct belt to be delivered I started it up with out the belt and found that 90% - 100% of that familiar whining sound came from the chains. After putting on the belt the sound was identical to the sound without the belt. My chain sound may be particulerly loud because my chains gears tensioners(oil psi feed) and ramps are all under 500 miles. I love that sound and I am very happy it did not get quieter by slowing the fan speed. I did hovever notice a power increase at higher rpm`s.
