If any of your believe (certainly used to by looks of this thread) that the high comp american or jap cars run big boost on pump fuel your massivley mistaken.
And most are horrendous to drive as to make half decent power with such high comp and run pump fuel they need massivley OTT exhaust housings and cams compared to a big boost low comp engine.
Sorry to pick up this subject again, what you said is true but only some in diesel-like engine speed's (5000-5500 as many ford engine tuners like to tune them
)
Like you know, all things in life take a certain amount of time to take place. Detonation occurs when the fuel as enough time to heat up. that said, we can easily have a 2L engine 9:1CR and produce 900hp on pump fuel, simply by increasing rpm!
Depends completely on the engine architecture. Evo - YES. Cossie - NO.
