It deffo needs some explanation for people about the current "oooh, high compression is mint, why dont we all run the usual 35psi 600bhp spec just with 9:1 compression and it will be fantastic and perfect on pump fuel" myth.

Need to explain, though its going off on a tangent a little, that you need to spec engines as a whole, and its not just comp ratio.
Ie a 250bhp per litre ideal spec pump fuel low compression turbo engine and a 250bhp per litre ideal spec pump fuel high compression turbo engine will have a very different turbo/cam/etc etc spec.

Need to explain why upping the compression a bit doesnt make up for lowering the boost a bit, if all else is equal.

Need to explain the effects, or lack of, of compression on boost threshold, esp in comparison to cam and turbo changes.

Basically it should be all about dispelling the common myths etc IMO.
