1) Now I know how to calculate the FDR, IDR and SPR and what the relationship is between them.
2) My TC came with the 39 tooth diff pulley and the 18 tooth drive pulley. Hence my IDR is 2.1667 and not the 2.4375 shown in the setup sheets.
3) I have now printed off a complete gear table for my car.
Many thanks from an extremely grateful Aussie "newbie".
