I did a comparison a while ago in a rather long thread that compared the 109 to the Spitfire (maybe? many threads that start about other things turn into 109 vs Spitfire debates) I will try to find it. Data was taken from the 109F-4 data sheets for cruise and from a page in one of Alfred Prices books that was supposed to copy recommended speed/altitude cruise for the Spitfire using various rpm/boost settings and giving the fuel burn for each.
