Makes more sense now. Explained very nicely.
If I ported a set of heads, and didnt make any adjustments to the wastegate at all, would the boost level shown to me on the gauge actually drop a little by itself, since there is less of a restriction through the heads into the cylinders?
Would I have to raise the fuel pressure to compensate for the now changed air/fuel ratio (in favor of air), just like it has to be increased when colder/denser air is applied?
As I'm kind of understanding, the intake charge temperature and the density seem to be two seperate issues. The cooler air is less likely to cause a given octane to detonate under compression. The density determines how much air is packed into the cylinder, creating the air/fuel equation that ultimately needs to be balanced. Just that both go hand in hand.
Am I on the right track with that?
