Hello all , I've been hunting for a tuner who is up to speed on the 3 cylinders power potential.
The three cyl configuration can take a lot of punishment and a lot more rpm than were getting in the Cooper and the same engine in the BMW i8 is giving a 100 more HP .
The 1.5 displacement is at a class break for some forms of racing and that's where I'm going with this.
So where would you go to get a 300hp build?

Who is going to bother developing tuning gear for the 3-cyl Cooper? The majority of buyers presumably aren't after a performance gain, as they would have bought a Cooper S - and buying an S is likely to be much cheaper than tuning up a Cooper.

Not always the case. There are a few owners that are autocrossing the Mini non S. There are some handling advantages with the 3-cyl. Personally I think the aftermarket will warm up to the 3-cyl. ;)

There is serious potential in this little powerplant... the old saying "there's no substitute for cubic inches" is ready to be challenged...

So far, I've only seen the piggyback system... need some miles on that system to see how it fares... no reason to think it couldn't work.

What we really need is more tech info on that 1.5 in the i8. That's the magic. (did anyone notice the i8 is the Formula e pace car?)

Agreed

Yes there is. It's called supercharging!
Yes, you can substitute pressure for displacement. The goal for the 3cyl is to see what can be done with what you got.
This type of pursuit has great appeal to many people and the results could be very satisfying.
Higher power from greater displacement doesn't mean much on some tracks ,there will be surprises for sure.!

"We tried a 1 Series prototype fitted with the new water injection system recently at BMW's test track in Miramas, France.
In this spec, BMW's turbocharged 1.5 litre three-cylinder petrol engine is claimed to produce 215 bhp and 236 lb ft of torque.
At low engine speeds, the effect of the water injection process was barely perceptible. However, at increased pace around the test track's high-speed loop, there was greater smoothness and refinement to the engine at higher revs. This was in part because of the lower compression ratio, which in turn lessened the knocking effect."
