I know that, but to get the ratio right ill need to get a custom pulley made for the end of the charger, as adding another to end of the crank pulley is a step too far as its v.long.
Esp as it has 2 spare places for belts (aircon and something else that im not sure).
Ive worked out the pulley size id need, thats not an issue.
