We have done a variety of these here on the dyno from the F30 335I, F32 435I coupe, and now this F36 435I Gran Coupe. The gains are all relatively the same. The difference with this dyno is we decided to try and test it closer to 1:1 in 5th gear of the 8 speed automatic transmission. This gave us MASSIVE torque numbers of near 400 ft/lbs and then horsepower of about 320awhp. We chose to dyno in all wheel drive to avoid any traction control issues. This combined with 91octane and about 100F temperature
