Fair point, didnt mention heat, higher CR means working the fuel harder, which also generates more heat.

Would be much appreciated if you would write that essay mate, you obviously know far more on the subject than the likes of me do, it would be a really useful thing to have in the technical archives section and im sure lots of us would be able to learn a great deal from you.

Weird that you say ALS is all about heat though, surely its largely about flow as well, and the point of the ignition retard is simply to avoid over reving the engine?

Again though, an article from someone like yourself would be greatly appreciated.


Maybe something you could do for us all when you get a spare half hour?
