Mode of operation optimised for maximum performance. Optimal Gear Shifting Ranges

I have come across some postings that touch with this topic indirectly via a side conversation. However, I would want to explicitly address this matter to enquire about people's own experiences.

During performance mode, I like to approach the maximum engine speed in the first and second gears when driving in urban areas, for obvious reasons. You have the opportunity to harness the engine's powerful sound and experience rapid acceleration right from the start. In my opinion, this is the optimal way to operate the automobile according to its intended design and purpose.

I would want to know the ideal shifting ranges for each gear. If you want to get the most acceleration from one gear to another, is it more advantageous to reach the maximum engine speed (red line) for each gear or is it preferable to shift slightly before reaching the red line, around 6-7k rpm? There exists a table of diminishing returns while approaching the red line and shifting up, as the gearbox needs to locate the next gear position. If the engine speed is far beyond the proper range for the gear, performance is compromised owing to the resetting of engine speed.

I am interested in knowing the ideal RPM ranges for moving gears 1 to 3.

In fact, I believe that due to the naturally aspirated engine, the power only becomes significant at higher RPMs. Therefore, this approach encourages reaching the maximum engine speed before changing gears, especially when the objective is to achieve rapid acceleration.
Although I have yet to use launch control on my vehicle, I believe it will enable each gear to reach the maximum engine speed before changing.

Personally, I use little pressure on the accelerator while shifting into 1st gear, and I avoid using excessive force when accelerating after making a bend. I have no desire to be included in a video that showcases the failure of Cars n Coffee events.LOL (laugh out loud):
I will shift into 2nd gear and rev the engine to 6-7k RPM. I refrain from pushing my automobile to its maximum speed.

Occasionally, I will accelerate the automobile to its maximum engine speed, but I have not familiarised myself with the optimal moments to change gears. During my time as a drag racer, I learnt that shifting gears at 7500 rpm, solely based on the engine's power output, was not always the optimal choice. To get such information, I would examine the specifications and curves of the cam. I have not previously engaged in such activity with this particular vehicle. In my opinion, it would be more advantageous to shift the vehicle at a point below the redline, when it is still generating power across the range, rather than waiting for it to nearly level out or reach the redline.

Greetings

The most advantageous moment to use the engine speed x is when the speed in the subsequent gear surpasses it, at this point the maximum engine torque is accessible.


The range is from 6200 to 8200.

If you want to determine the optimal shift locations with precision, the most straightforward approach would be activating Dynamic Mode in your vehicle, selecting the Automatic gearbox setting, accelerating vigorously, and observing the computer-controlled shifts. The computer is programmed to optimise the optimal shift spots in each gear during Wide Open Throttle (WOT).

I have often engaged in the WOT (Wide Open Throttle) technique in Dynamic mode, and it consistently causes the vehicle to shift either directly at or in close proximity to the engine's redline.

What is the reason for it not to? That is the location of maximum power.
