Basicly im doing an assignment for my motorsports degree and here is what the questio says
"You have been asked to provide a specification for a race transmission. The engine produces peak power of 500kW at 12,000 rpm and useful power from 8,000rpm. The transmission must be a 6 speed type with integrated final drive and should give a projected top speed of 220mph on 16-26 /15 rear tyres. You should specify a set of gear ratios, with projected top speeds in each gear, and a final drive ratio, giving reasons for your choices."
Basicly i need to work out the ratios for the gears. Tho im a bit stuck on finding out the primary ratio for a forumla
Overal ratio = Primary Ratio x Gear Ratio x Final drive Ratio
I've allready managed to work out the Final drive ratio as 4.22:1 and the 6th gear ratio as 1:1 but i can't seem to get primary ratio which is kinda crutial to the rest of my calculations.
Any Ideas???
