Manual Timing Belt Tensioner Conversion:
Timing belt should be tensioned such that the longest part of the belt can be turned 90 degrees. If it's whining like a supercharger, it's too tight. Belt tracking too far in is usually a bent / dented roller from an overtorqued nut
The tensioner nut should be tensioned to 33 ft*lbs
Note: If you have a tendency to overtorque you should use the IE manual timing belt tensioner backing plate to prevent your roller from bending.
