Overdrive is 1.58:1; I would turn the fan with the stock drive, bolt the
fan ring to the turkey roaster, and find out just how much better the cooling
was improved. If things went OK, I would consider the sped reducer from
Clark's to lower the RPM so as to reduce the HP requirements.

Very interesting concept and it sure has a lot of blades. A stock Corvair
fan has an overdrive but I don't know the ratio. At what RPM would you
plan on turning this fan?
