[Land-speed] Blower pulleys and belts

[speedtimer at beyondbb.com]

I sent Skip a PM . I have a blower over drive chart and will try to post on 
line. Trying to get my scanner back on line. I will post it when I do. What 
Rich said is correct, just like gears. Blower drive service has some charts 
on line.
