Be sure to use a cog belt tensioner on your cog drive Graeme.

Hi @Orv Neisingh Yes I always use a back side tensioner it mounts to the plate you can see below the belt.
That is my main and small cog belt pulleys, I use the spoke design very similar to the old chain cog design so there is a lot of open space between the spokes, thus allowing hot air to pass through and together with the dog box electric fan it keeps the engine bay a lot cooler , and that hot engine air is not going through the radiator.
