As time allows, we have been doing  testing on a dyno regarding the 
above and have some data. But at this time  it would be premature to 
release part of these data before all tests have  been completed.

What I can say is information presented in the Corvair  SAE papers, 
Bob Helt's Classic Corvair and How to Hot Rod Corvairs seems  to be 
quite accurate. You could extrapolate the HP curve for a specific  
engine RPM based on this information and this would net some very  
reasonable data.

Testing has been done up to 7,200 RPM with the  stock magnesium fan. 
Tests were run with and without a fan belt. No tests  have been done 
with a cut down fan, 1/2 speed pulleys, etc. These, as well  as other 
tests are planned as time permits. If someone has a specific test  
they would like to investigate, please post me OFF LIST so we can  
discuss this.

I would like to thank Mark Wright for loaning his  engine for the high 
RPM  testing.

Cheers!

Thanks for the verification of the data; I'm glad to know that it's current  
so I don't make myself any bigger horses' a-- than I have to.
I'll be glad to hear from you when you've finished your testing.
