I thought I would start this topic to show how many people around the world have been on a dyno with their Coopers/Ones.
This is a Cooper with software, K&N Typhoon and exhaust.
It shows three lines for HP and Torque.
The green one shows the stock HP.
The other two show the HP with all his mods and a more finely tuned software is what created the black line.
HP : 122 at flywheel
Stock : 111hp
Drivetrain loss : 17%
Dyno :Cartec
This is a Cooper with aFe intake and custom exhaust.
He produced 119,7hp at the flywheel and 101hp at the wheels.
Drivetrain loss = 18%.
Dyno : Superflow
