Correction made Engine horsepower = 700 , Brake RPM @ max power = 8000 , Torque arm length (mm) = 500 , Load cell rating = 125.42 kg

OK , been busy at work and hopefully will catch up and back on the dynamometer over the weekend. Toying with the numbers between 300mm and 500mm long ...

Hi , space in the clockwise rotation and to compress the S-type load cell is very limited to couple up but on the flip side (opposite of compression) ...

This paragraph should of read in the very first post should of read as follows - ( wouldn't allow me to edit the first post ) Once I have made the mea...
