MINI JCW
I agree the 172cup should be slightly quicker (everything else being constant)out of the 172/182 as it has the highest power to weight ratio.
here is a list of the power to weight ratio in bhp per tonne
172 - 157
172 cup - 170
182 - 167
182cup - 169
182 trophy -169 (although some would argue 170 due to lighter wheels)
just to confuse the issue though the 182 has differnet tyres and its max torque comes in slighlty earlier in the rev range and obviously this will affect acceleration, also Im not convinced one little bit by the 172cup producing the most power.me thinks a different day would tell a different story
