<VV> Re: Incremental Pulley accurate test info?

[Taruffi57 at aol.com]

Hey guys, I have an Otto pulley with the appropriate belts and spacer  
washers which I have yet to install.   I have been advised by several  that these 
things can be a real nuisance with thrown fanbelts.  I just want  the facts of 
any known proper testing as to the HP increases possible and  certainly, candid 
comments on that fanbelt problem.  
 
Right now I have done some autocrosses and using Lon's spring loaded idler  
and a Clark's belt, have not dropped a belt.  I WOULD like to have that HP  
increase though.
 
Thanks for your time.
