<VV> 3-Cylinder Vair motor

[FrankCB at aol.com]

Reminds me of the time many years ago when son Jim  and I decided to take 
"Joe Cool" (66 Monza 95hp PG A/C) to a  local autocross.  After the autocross, 
the car was hard to start but  we finally got it going to discover one carb was 
completely nonfunctional (found  out later that the main jet was completely 
blocked with silt).  So we drove  home on the highway using only 3 cylinders.  
The engine ran relatively  smoothly but with much less power and a lot more 
heat.  Fortunately, I had  installed a calibrated aftermarket CHT gauge and even 
more fortunately the  pickup sensor was on the side of the 3 firing cylinders. 
 Whereas the  cruising temp with all 6 firing was around 350 deg.F, with only 
3 firing, it  easily reached 450 and even higher.  We frequently had to run 
at lower  speed on the shoulder everytime the temp started to climb much above 
450.   But we made it home safely.  I figure our average A/F ratio was about 
24 to  1.<GGGG>

Scott: I  was at the Georgia  Spring Fest at Helen GA .  I saw it run and I 
was  amazed as to  how smooth it ran . 1-2-3 Cyl's were firing . 2-4-6 no 
cyls 

at all .  he cut off old 2-4-6  Con rods to have something to counter  
balance  
.  I would guess it will develop 60HP . You got to see it to   Believe it '

Actually  1 -3 - 5 were the firing cylinders, and it should run pretty   
smoothly (everything is relative) No worse than a counterweighted Geo  
3-cylinder  
motor of the mid 90's. - I'll bet the Geo was also about  half the 
displacement  
of the late Vair. Hmmmm? Probably about 60 HP  as well. Hmmm? Of course, with 
the  three left side cylinders of the  Vair not firing, the car would have a  
definite pull to the right!  <grin> - Seth
