could you give details of what motors you are running in which cars and on what gearings etc...
I am running a kit spur,84 i think? and a 16 pinion which gives a final drive ratio of 12.07. Richard Lowe suggested my batteries could do with being renewed. They are about a year old and are 4200 unmatched cells. What do you think? Maybe i should go for a lesser load motor?
