It seems in the world on mini's as in Mini Cooper, there is a camshaft called a scatter cam. It changes the timing for cylinders 2 and 3. I've heard of changing the timing to have 1 and 4 firing at the same time as well as 2 and 3 on 4-cylinder motorcycles but never changing just 1 and 4 or just 2 and 3.

It doesn't seem that changing the way timing works on just two cylinders would have much benefit but I'm probably not looking at it right since it seems so many Mini Cooper owners want this done. So what am I missing here. Please make me smarter.

What is a scatter camshaft?

Why would you only change cylinder 2 and 3?

What are the ultimate benefits to using this type of a camshaft?

Why do they call them 'scatter cams'?

TIA and Cheers!!
