Mini 3-cylinder Cooper Tuning

Hi guys,

I must say I'm impressed with the performance that the Cooper's 3 Cylinder engine outputs. After having driven it on mainly B-roads for over 2000km It's given me some smiles. However, I'm sure a lot of us would share the urge to explore how far we could take this beautiful piece of modern engineering.

Everyone is talking about the tuning of the Cooper S, and there's been some success in improving performance and so forth... but to me the most revealing fact is that our engine is practically the same or very similar to the one found in the new BMW i8:

"Then, at the rear, a new 1.5-liter turbocharged three-cylinder engine, rated at 231 hp and 236 lb-ft of torque drives the rear wheels through a six-speed automatic transmission. The same engine is also used in the new 2014 MINI Cooper Hardtop, albeit in a slightly lesser state of tune"


Now, I'm far from being an expert and have limited knowledge and info about this particular case and tuning in general, but if the actual mechanics and physical parts of the engine are identical to that of the i8, this would mean that with a performance tuning of the ECU a whole lot of power could be unleashed!

Cooper 134 hp VS. i8 231 hp... Even if we could only tap into 20-40% of those potential gains in performance (due to other restrictions and components that are not part of the engine, eg/ exhaust, air intake, etc). It would make our Coopers and absolute Hoot to drive and potentially rival the performance of a Cooper S. Too good to be true?

If i were a tuner, I'd be digging deeper into this, because it 'sounds' promising.

(Now it's when I wait for someone to burst my bubble and tell me I'm an ignorant ;) )

Is the 230hp not due to a petrol engine and electric motor working together?
