It's my  understanding that a slipping belt will get hot (also logical) and 
fail  rapidly.

Well - I suppose that if it is dry and the whole of the rear of the engine  
is dry (not too common on the Vair Motor) a loose belt could get hot and fail.  
But I have run well-lubricated (CRC Silicone Spray) Corvair belts for many, 
many  hours - at high speeds -  and never had a failure. Most of the Silicone  
sprays leave a slippery silicone residue behind as the carrier fluid 
evaporates.  This is what you need to remain on the pulley/belt system. I have run them 
with  and without spring-loader idler pulleys installed. Without them, a  
close-to factory tension is best (It is hard to recommend the  
"TURN-THE-ALTERNATOR" test with the silicone residure coating in place). The  little slippage 
from the lube is not really enough to affect charging.  Although, in fairness, I 
am talking racing/performance use, not high  electrical load usage. And I 
would usually rather the belt slip a bit on a  pulley, than grab ahold and 
depart!   -  Seth
