A car that makes its peak tq from 2000-5500 RPM such as my old 335, had great acceleration at any given RPM but peak power came around 6000rpm even though it redlined at 7k. It was great on low speed races but it was not once you stay get to speeds (higher rev range). The perfect example is the AMG cars VS M5. AMG cars are faster at lower speeds but the M5 smokes most of them anything over 120mph. Why? Because it accelerates for longer period of time with its higher redline. Same example can be used with s2k vs other cars that had twice the tq such as the z33 also ferraris vs lambos. Every manufacturer has its own way of building an engine, its just a matter preference what you are into. Me higher redline and higher peak hp > than bunch of tq and lower rpm peak power.
Both are very important and depend on each other. The thing that will not change is that higher RPM peak power = less tq and vice versa. Again TQ wins races is not an accurate statement.

Regardless of if it has more HP or torque, a certain weight requires a constant force to achieve a certain acceleration. The amount of force required to achieve a certain acceleration is a value bound by the laws of physics, and regardless of how much HP or torque the engine is outputting doesn't matter in achieving that. If you want your car to run 11's or 10's or whatever, that
requires a certain amount of torque at any engine speed you want to produce the amount of power necessary to propel that vehicle at that rate...
I'm unsure of how either TQ or HP would win a race since HP is a value obtained by calculation of TQ and engine speed. If you have the opportunity of having your engine stretch out the same torque curve over a higher RPM range, then of course you would since it would be producing more HP at the same torque values. So in closing, what argument is it? It's not a battle between HP and TQ, but rather, how highly you can produce that Torque #
