Hi  all,

I can't  remember when a topic has gone on this long( unless people   were
flaming each other) but the only thing I've seen that would seem  to  work
without loosing horse power or performance his a small gas  engine  driven
cool fan. 



How about another one. Most  every Corvair, whether street driven or in most  
competition need to  have the exhaust muffled. That muffler, no matter what 
kind,  is a  parasite on the motor, even if just the extra weight it adds. 
Does 
the  hot  exhaust of the Corvair carry enough heat/volume to drive a  
Turbocharger 
style  cooling fan that could help cool the motor? Use  the inlet side only 
for  handling cooling air, leave the motor  normally aspirated. Send the 
compressor  output directly into the fan  area of the motor. What is the CFM 
of an  
E-flow turbo on max boost,  or some other exhaust driven turbo/fan set-up. 
Would  
the exhaust be  restricted? Yes. But the muffler(s) does that now.  Is there  
 
anybody old enough to remember the "Turbonique" direct drive engine. It  used 
a  
small gas turbine, as I recall, to direct drive the rear  wheels. The nice 
thing  about an auxiliary drive for cooling the  motor is that it is 
(generally  
speaking) unrestricted by sanctioning  bodies. How about a small gas turbine  
driving the cooling fan on the  motor? With some kind of gear reduction to  
keep 
the speed of the fan  down to a reasonable RPM. - Seth  Emerson     




I have seen a Turbonique in action (not on a 'Vair though); it was hell on  a 
dragstrip.  Pity they didn't sell well enough to stick around.
