    Motor Controller & fresh air blower on rack above motor. A PVC plumbing fitting is a tight push fit into the hole on the front motor mount , I think I'll make an alloy piece , the cooling air will be blown into there.

    Whilst waiting for batteries and other parts I decided to make Chill plate for the Motor Controller , rather than a finned heatsink . Started off with a 300 x 300 x 22mm alloy plate.

    The controllers do get hot under constant load and cut performance back when they go over 60c . Chill plate solves the problem.








    I ordered a VW Auxiliary coolant pump, its a nice small pump with isolated mount included. no specs on current draw but I doubt it more than 15 Watt .
