This links to the turbo section, there is an engine section too. I did not know all of that.

And yes, I have had a day off, so spent most of it PHing.

How Stuff Works said:

Therefore, you get more power from each explosion in each cylinder

If the air/fuel mix is 'exploding' in the combustion chamber you have problems. The air fuel mix in the combustion chamber burns, if it explodes then severe engine damage usualy follows fairly quickly.
