Just had the MCS rolling roaded, stock with an Alta intake and Cat back exhaust, mad 159bhp and 161lbft of torque. was hoping for me, I think it was due to them running the car with the bonnet open, and therefore the Alta getting some of the latent heat (that it wouldn't get normally) and the IC not being as efficient with the fan not pointing at it.

Anyone any thoughts ???

Graphs are nice and linear though

u maybe forgetting the drivetrain loss... 11% in the mini.. so read 163hp from the factory turns to about 145-147hp on the wheels... sounds normal to me if it's just intake and exhaust at the wheel

Yup, see the plot here from a recent dyno day spent at AMD in Bicester.
See if you can work out from the plots which cars are which - Mini D, Mini One, Mini Cooper, Mini Cooper S, Tuned Cooper S !!
