Ernest,
The steel Corvair fan appears to be an early one with slanted blades that will pump
best in the correct direction (clockwise from your cockpit) but again no OD or ID......
Perhaps Pat Panzera knows the Corvair fan dimensions............

FWIW, the Corvair guys regularly throw away one-piece magnesium cooling fans that are geared to spin faster than engine RPM, which is red lined at or a little over 5000 rpm.

They also made a steel unit:

Yes, I did. Takeaways: -the fan will flow between 10k and 12k cfm at 6000rpm -the fan will hold together up to 10k rpm What I couldn't find were any technical drawings to derive dimensions from.

I found the thickness is 37mm (1.46"). I could stack two in the space I have if the OD is around 10.4" and the ID is just over 6.5".

anyone here work on Volkswagens? They have a fan to cool the engine that looks like the shape I need, but I'm clueless as to the dimensions.
