Ok I got to ask
This is going to sound like a dumb question I have 671 blower 12% underdriven 38 tooth on the top. I have asked a lot of pople why some blowers have that whining sound and mine dose not, you could here it but some cars you could here from two blocks away. I have a 350 sbc roller motor I even put noisy gear drive in and still can't get that nasty sound. What do you think.
Thank you

That is where the whine sound comes from. Most of the street cars with a blower, have a 1/2 pitch belt. The teeth on the belt are flat. When the teeth mesh with the pulley, the air is smashed and there is your whine.
An 8mm pulley and belt are of a rounded shape, and are not nearly as loud.
