"This is a data graph of the impact of braking frequency, downforce changes, and braking system temperature!"

"Yifeijun completed the Singapore track test in three practice sessions, and now we can use this data map to make the final car tuning!"

Yamamoto Ukyo's tone was so excited that he could even hear the tremor in his voice, because Zhang Yifei had completed an impossible track test and had obtained a large amount of sensor data to produce this icon for data analysis.

Not to mention Yamamoto Ukyo, even Korsell looked at Zhang Yifei with a complicated expression when he saw the data map on the computer.

Because after practicing for the first time yesterday, Zhang Yifei did not just go out of the station and continue to run after a simple adjustment, but told himself a whimsical and crazy idea. Even with Cosell's radicalism, he thought that Zhang Yifei's idea was impossible to achieve, and now the facts are in front of him, and he has done it!

In addition to the driver's skill requirements, the street race also has extremely high requirements for the stability of the car, and the brake cooling system is the most important!

Because F1 cars are air-cooled, the layout of street races is destined to be not too fast in many corners. Once the speed of the car is not enough, then the air volume of the forward air outlet will be insufficient, causing the braking system to overheat, which will affect the braking effect.

That's why, when a F1 car is idling, two maintenance technicians are holding blowers and blowing air into the air intake of the car, which is to ensure that the air cooling failure will not overheat when parked.

And in order to ensure that the braking system can be cooled down quickly, there are up to 1,200 small holes in the brake discs of Formula 1 cars. In addition to speeding up the cooling of the braking system, these holes also have another important task, which is to quickly transfer heat to the tires and maintain the stability of the tire temperature.

Think about the average car, the tire temperature will rise after driving for a long time, but the temperature will rise to a limit, and the upper limit will be reached. Therefore, ordinary vehicles drive for hundreds of kilometers, and if you touch the tires, it will be hot at most, and it will definitely not reach the point of rapid burns.

But just after the F1 tires are finished, you can touch them with your hands to burn off a layer of skin, because the tire temperature requires hundreds of degrees Celsius, and the rubber on the surface of the tire needs to be melted to achieve a semi-solidified state similar to chewing gum, so as to ensure amazing grip.

It is difficult to reach hundreds of degrees Celsius just by the rise in the air temperature inside the tire. Therefore, an external condition is required to heat, and the vehicle heat source is only the braking system in addition to the power system.

The braking system can conduct heat to the tires to ensure that the tire temperature reaches the best road feeling state, but if the temperature of the braking system is too high, so that the rubber on the surface of the tire melts too quickly, then it is equivalent to the tire wear in normal races, to open an accelerator.

If the wear is too fast, the tire thickness will naturally become thinner, and the tire temperature will exceed the safe value, and the consequence of this situation will greatly increase the probability of a puncture.

That's why, before Alonso gave feedback on his car tuning, Korsell replied indifferently, did he want to blow a tire on the track?

There are two ways to solve this problem, one is to increase the air pressure and mechanical grip of the car in the corner, and reduce the dependence on braking deceleration, so that the temperature of the braking system can naturally be maintained within the safety line.

The other is that the artist is bold, through the extremely accurate empty throttle deceleration coordination, as well as just the right braking point calculation, relying on their own driving skills to play the operation of dancing on the tip of the knife, desperately controlling the critical point of the braking system temperature.

Previously, Zhang Yifei chose the first option, but too much downforce would affect the acceleration of the car. Alonso was confident in his skills, so he opted for the second option, to go to the edge of the limit with high risk.

Zhang Yifei chose a safe tuning plan, not because he didn't dare to take risks, but because he was very confident about winning the Singapore Grand Prix. Even if you lose a little bit of acceleration, as long as you are fast enough, you can still get on the championship podium in the opening race.

Later, Alonso's performance gave Zhang Yifei a warning that he just had an advantage in the night battle in Singapore, which did not mean an absolute victory. With this conservative choice, it's okay to run to the front row, but if you want to become a champion, it's really not very safe.

However, Zhang Yifei did not take Alonso's path, but chose another more difficult path, that is, through an extremely accurate track test, the temperature changes of the braking system at different points in time were recorded.

Then through a variety of different pneumatic, suspension, engine and transmission tuning, to constantly test where the critical point of this temperature upper limit is, so as to finally make a relatively perfect Singapore tuning!

Practice is the only criterion for testing truth! Isn't it true that the new track doesn't have any setting experience? Then rely on laps to run the data on the track, isn't that there?

This kind of thing is very simple to say, but it is extremely difficult to do, it was supposed to be a post-race data count, with 22 drivers working together to complete the historical data collection, and now Zhang Yifei has to rely on one person to complete the preliminary data analysis before the race.

It is not only a matter of engineering quantity, but also requires Zhang Yifei to make accurate control feedback on any subtle changes in tuning, and completely treat himself as a racing machine.

It is precisely because of the great difficulty that Korsell felt that he could not complete Zhang Yifei's crazy idea after hearing about it yesterday.

It's just that Kosell is also not the kind of person who likes to persuade hard, Alonso chooses to take risks, and Kosell respects his choice.

Zhang Yifei went to challenge the extreme difficulty this time, and Kosell also respected Zhang Yifei's choice.

The road is on its own, just be prepared to bear the consequences.

As a result, Zhang Yifei did it, and even what Cosell thought was impossible, he did it, which was a long time since the old German man felt this shock.

"Fly, now we can run as fast as possible with the least risk, you have created a miracle!"

Boss Prost opened his mouth to speak, his mood at the moment was surprised and happy, because Zhang Yifei's crazy decision, before the three practices, only Koser, Yamamoto Youkyo and Zhang Yifei knew about it, and he didn't know it very well.

Zhang Yifei understands Prost's conservative character, and if he is told, he will inevitably meet with opposition. Even if it is finally carried out strongly, it is equivalent to challenging Prost's prestige, which is not a wise move.

There is an old Chinese saying that history is used as a mirror to know the rise and fall. Prost is a good talker, but never think that he is good at talking, so he constantly challenges and vetoes the boss's opinion.

Zhang Yifei needs to maintain the balance between his decision and Prost's opinion, because his ambition is not to control the overall situation, or even to devour the Prost team, Zhang Yifei's goal from beginning to end is to aim at the technology behind the F1 team.

If there is no Prost as a "middleman", any F1 team in Europe will not give the Chinese the opportunity to steal the teacher, even if they buy the Prost team with full authority, it is useless, and political factors will immediately intervene, just like the later Geely acquired Volvo, unable to use technology and patents.

So Zhang Yifei cut first and then played, maybe Prost would be unhappy when he learned about it, but when the results came out, it was definitely a pleasant surprise, and he wouldn't care so much about it.

Of course, this premise is that the results are good.

"That's right, I think this flight can take pole position and Alonso can sprint to the top five!"

Team leader Henry is also very excited, the appearance of this test data is equivalent to removing the biggest stability threat point of the street race, and the rest is to see Zhang Yifei's driving skills and performance.

But the crew members are very confident in Zhang Yifei's driving skills and performance, at this moment, in the hearts of everyone, the ambition to defeat the Big Three and win the pole position is crazy, and the victory will belong to Prost!

The only person who was more surprised than happy may be Alonso, since this data map came out, he has been staring at Zhang Yifei's back with disbelief eyes.

After three practice matches, Alonso's results are very good, and if you compare it with his level last year, it is even better than the word "good"!

The fastest lap in the first practice was eighth, the second was sixth, and the third practice directly killed Ralph Schumacher to move up to fifth place.

This kind of result is qualified to compete for pole position and even end up on the podium in the main race. You must know that in the rookie season last year, the first brother ran down twice in the points area throughout the year, and never went up to the podium once.

With such an exaggerated result in today's opener, you can imagine how proud and proud Alonso would be with his character.

And in comparison, Zhang Yifei's results in these three practice games can be described as miserable, and it is not as good as the lap time of his rookie season last year. Even if Alonso has seen Zhang Yifei's lap time in the racing simulator and doesn't think that his strength is like this, he still has a sense of pride in his heart, looking forward to surpassing and defeating Zhang Yifei at the Singapore Grand Prix!

Now that he has learned the truth and understands that his so-called "victory" is just Zhang Yifei challenging a more difficult matter, Alonso suddenly had a sour nose and a feeling of wanting to cry.

Why is this Chinese kid so strong, and when will he be able to defeat him?

"Alonso, you go and compare the test data of the fly, choose the tuning plan that suits you best, and the qualifying round will start soon."

Cod didn't feel the change in Alonso's heart, on the contrary, he was very excited to let him dip in the light.

Although the team data is shared, there is no such thing as a stain, but in fact, this test data was completed by Zhang Yifei alone, and Alonso did not make any contribution.

Keep your head down and learn, or do you persevere to the end and prove yourself by limiting your control?

At this moment, Alonso looked at Zhang Yifei, and fell into a deep contradiction in his heart.
