Title: Transmission ratios Post by: Andy Sykes on January 30, 2014, 17:33:59 pm Hi guys, my transmission is about to be started on and being as my engine hasn't been dynoed yet I don't have any real idea where the power will be, but speaking to others and looking into it it looks like it's going to be 5-5500 rpm so two fixed things I have at the moment are 26 inch tyres and 3.88 R&P
