In the 1930's, the plane came from aerodynamics limitation in their race for speed to refined monoplane configuration only limited by their engine's power.

No, top speed in level flight is ALWAYS limited to the point where engine power (and efficiency in getting that power into actual thrust) matches drag, no matter how old the aircraft is.

Nowadays, a fighter pilot just slam the throttle and race toward his maximum airplane's Mach as the aerodynamics is much more refined than in the 40's. He will even raise the airplane nose to reach less denser air to increase it's speed !

No, the modern fighter pilot has less to gain by dipping the nose because the power-to-weight ratio is so much higher now.

Just slamming the throttle forward could prove so lengthy that the engine cooling system would hve difficulties reaching it perfectly level (especially in the middle of a mission deep into enemy territory)

No, any pursuer could slightly dive as well, but it would be an advantage for the aircraft with less increase in drag with speed.

Diving is simply a convenient way of speeding up.

Nothing personal Tomcat, but either you need to read-up about aerodynamics, or you are trolling.
