My main topic of discussion is -- does direct injection always net the "end-user" better fuel economy?
Let's take two engines, both 5.3. One is a Direct Injected Gen V 5.3 and the other is a regular port-fuel injected Gen IV 5.3. Both equipped with Variable Valve Timing. The DI motor has higher compression.
I know in terms of performance, that is a no brainer... but how's about fuel economy considering everything else is the same.
I am in the beginning stages of a new project and at a choosing which path I am going down. I am trying to decide if the DI engine could net better MPG.
