[alfa] Tensioner

["Allen Mitchell" <allenom@xxxxxxxxxxx>]

I have been running the Zat tensioner on 2 race engines for about 3 years.  
I have not noticed a huge difference in tension betwen cold and hot.  I set 
the tension to about 1/4 inch of belt deflection between the cam pulleys 
with the motor cold.  Now, I live in South Carolina, so the motor is usually 
not colder than about 70 degrees.  Also, I am not 100% sure that the timing 
belts experience a large amount of stretching.  After initial installation, 
I do not find myself needing to retension the belts.
Again, these observations are on race motors, not daily drivers.

Thanks,
Al
