"Specifically, the  second car - the 95 PG - was a borrowed car and  as I 
drove 
it I was mildly  surprised at how well it ran. I hadn’t ever  worked on this 
car either!"

Ken, no wonder it ran so well!! <GGGGGGG>   Just kidding,  Ken!  After that 
trip you took me around that FAST autocross track a few  years ago, I'll attest 
to the fact that your cars run exceedingly WELL.

"Now  for  some observations; there was a lot of air reversion through 
the  electric fan  when it was running statically. In comparison the stock 
fan  
had NO air reversion  through the fan.  Even with the electric  fan and the 
air 
doors  open, there was still air reversion back  through the fan. Not as much 
mind you,  but there was still air  reversion."

Ken, that just confirms that the electric fan doesn't put out  enough 
PRESSURE to get the air flow through the Corvair engine.

"The numbers we got were very close to 
the 110 PG with about the  same  curve on temps. You will find the two 
engines 
very similar even  though they were  a 110 and a 95. I won’t cite numbers 
because 
that  will be in the graph from  Frank. One of the common misconceptions is  
that the 110 is the worst of the two  engines for heat because of the  
compression ratio. Well, I think we can put that  theory to  bed."

Actually, since the 110 has higher compression ratio than the 95, it  should 
be more efficient in converting gasoline energy into motive power.   That 
means LESS energy is wasted as heat so the 110 should burn LESS fuel for  the same 
road load and have a LOWER cooling requirement compared to the 95  hp engine. 
 This assumes, of course, that everything else is equal (and it  never is.)
    But maybe we should consult the "Oracle" for the  "true facts" on this 
matter. <GGG>
    But seriously, we have to extend a BIG vote of  thanks for all the 
massive efforts you guys put forth in setting up, testing and  reporting these 
results.
    Best regards,
    Frank "grateful"  Burkhard
