“Newby” question:
We just completed updating our Top Dragster ProCharger F-3R-112 Blower Belt to a new 3 inch STAR RACER BB-14-1750-75-SR; 14mm 1750 (68.9 in. x 3 in.).

It has a new idler pulley on the bottom middle to get belt clearance to the chassis and body and an adjustment pully on the middle top.

What is the best way to get proper belt tension for ensuring no excess bearing loads on the crank and ProCharger?
