<VV> How about the cooling fans from these engines?

[BobHelt at aol.com]

Oh come on now!!  That isn't a fan problem. That's a  problem with the 
heads and cooling surfaces. A fan capable of developing greater  cfm and/or 
greater pressure just isn't going to force that much more air thru  the heads 
and/or rest of the engine.

Also, we  know the Corvair fan is horribly inefficient, and for high perf 
apps, it just  isn't enough. Ask a turbo owner or anyone who really races 
these things, and  they'll all tell you, the stocker just isn't up to the job.
