Riding a Kawasaki H2 to chase the high-speed rail, the school beauty was moved to tears

As soon as they started, the attention of Peko, Martin and Ma Wang was all focused on Qin Chuan.

To be precise, it was on Qin Chuan's car. The three of them knew that there was something wrong with Qin Chuan's car. They knew that there would be no clues during the warm-up lap, but they still wanted to take a look.

The cars rumbled through every bend, the group was very loose and the speed was quite slow.

But every audience member present knew how fierce the competition among these people would be.

Under the helmet, Peco's eyes were full of sharpness. He suffered a great blow from the mistake in yesterday's sprint race, but today, he adjusted himself and wanted to hit the championship.

Qin Chuan's racing problem also gave him an opportunity.

The cars passed one bend after another, and the fans in the stands were excited again.

The warm-up lap ended quickly, and Qin Chuan's car finally reached the finish line again. He stopped at the pole position, supported himself with his feet, and began to lower the rear shock absorber.

One by one, the racing cars returned to the starting point. After a moment, the rear shock absorbers of thirty factory cars were all lowered and positioned in their respective positions, quietly waiting for the start command.

The entire starting point was instantly filled with a tense and depressing atmosphere, with the roar of violent engines everywhere.

"Thirty cars have returned to the starting line. The race is about to begin. The Portuguese Grand Prix is ​​ready to start. The red light is on!"

"Wait, there seems to be a problem with Oliveira's car over here, and the start is suspended."

In the commentary booth, Wei Ran's voice suddenly stopped, and his attention shifted to Oliveira who was starting from the middle of the pack. The driver who was about to start the race also relaxed his momentum and turned back blankly.

Oliveira's right arm was stretched out and raised high, as if there was a problem with the car, as if the rear shock absorber could not press down.

This episode did not delay the race for too long. Soon, Oliveira's team staff came up to deal with the problem with the car. It took less than a minute to solve the problem. However, since it affected the start, he had to start from the door of exit P channel due to the rules.

Oliveira was naturally very angry about this, but this was the rule and no one could violate it.

After the little episode, five red lights came on and the race was restarted. All the drivers held their breath and looked straight ahead, pressing down their right hands slightly. The engine speed soared to the limit, and the beasts under their crotch roared again.

Start and continue.

"Okay, red flag waved, green flag withdrawn, five red lights on!"

Wei Ran and Xiao Zhang also quickly got into the mood. Their expressions instantly became tense and their faces became extremely serious.

At the same time, all the fans around the starting stand fell silent. Some were holding their phones, some were just sitting there, all staring at the group of cars getting ready to start at the starting point.

The red light above Qin Chuan's head was shining abnormally, and the eyes of hundreds of thousands of people at the scene were all focused here, quietly waiting for the red light to go out.

Finally, after remaining on for a few seconds, the five red lights suddenly went out.

At the moment of extinguishing, the group of racing cars that had been roaring suddenly became violent and burst into a roar.

Thirty racing cars shot out from the starting point at the same time, like beasts out of a cage, and were ejected together.

The group of cars officially started off, like galloping wild horses.

"The red light goes out, the race begins! Qin Chuan's start was very fast, almost leaving the others in the dust. Peko was not slow either. Martin's rear wheel slipped a bit, but he regained stability on the way to the second gear. The competition in the front group was very fierce, and everyone pushed the speed to the limit!"

Thirty racing cars were ejected at the same time. Xiao Zhang and Wei Ran immediately began to explain the starting situation of the group of cars. They spoke very quickly, and their magnetic voices continued to come out.

On the track, Qin Chuan lay low, and after a launch start, he gradually increased the accelerator with his right hand and quickly shifted gears while pulling his legs back. He did everything to the best of his ability and in the most detailed way.

The car shifted into second gear, then third gear, and went downhill. When the car shifted to fourth gear, Qin Chuan's upper body suddenly straightened up, his line of sight instantly turned from the front to the side, and he began to brake to prepare for the turn.

Looking towards the center of Turn 1, while his sight shifted in advance, his right hand touched the brake lever and pulled it hard, with the first pull using 70% of the force.

The car that was originally rushing forward madly suddenly stopped after this force, and a huge force was transmitted along Qin Chuan's two-fingered arms.

Qin Chuan exerted force with both arms, and his left foot was also not idle. He quickly downshifted from 4 to 2. The engine sound that was originally bursting out suddenly hummed twice and the rhythm immediately changed. At the same time, the rear wheel left the ground.

The whole process lasted just over a second before the car tilted into the turn.

Braking into the turn is complete.

Entering Turn 1, Qin Chuan leaned outward with his upper body, hung sideways and was the first to enter Turn 1, rubbing his knees, then quickly stepped on the accelerator towards the center of the turn.

All the movements are done in one go and at an extremely fast speed. This is the rhythm of the highest group in MotoGP.

“Qin Chuan was the first to enter Turn 1, leaving Peco behind him with no chance at all.”

"Peko is the second one to enter the corner, Ma Wang is the third, and Martin is the fourth. The group behind is very chaotic, everyone must be careful!"

On the commentary stand, Wei Ran and Xiao Zhang looked nervous as they watched the cars entering the turn after the start.

Martin made a small mistake at the start. Although he stabilized later, he was overtaken by the horse king at the moment of the start. Apart from that, there was not much change in the top four.

Before Turn 2, Qin Chuan quickly shifted up gears after exiting the turn, and at the same time, he moved his upper body toward the seat, from second gear to third gear, and then squeezed the brake lever again. His straight body began to move down as the car body stood upright, and he hung sideways into Turn 2, looking towards the center of the turn.

Every time he enters a turn, Qin Chuan not only looks at the inside of the turn, but also pays attention to whether anyone is attacking from the inside.

It turns out that there is no such thing at the moment, and this is also their tactic.

Sprint at full speed from the start and don't give others any chance.

After a whole afternoon of adjustments yesterday, the problems with his car were improved, but the improvement was not so thorough. According to the simulator data and John's estimation, the car may still have problems later.

So the plan they made was to lead the opponent away as much as possible in the early stage and not give the opponent a chance to fight with them.

To put it simply, it means allowing Qin Chuan to achieve pole to win.

Lead the whole time and don't give those behind you a chance to get close.

They studied it yesterday and found the problem with his car.

The problem with his car is still the tuning. Ultimately, it is still the tuning that is the problem. However, this time it is not directly related to the tuning, but indirectly related.

That is, the tuning caused a problem in another part of the car, which caused overall problems with the car.

He adjusted his car himself during the test race, drawing on some of Stoner's old data for tuning. Although there are big differences between today's cars and those of Stoner's era, he has actually adapted quite well.

This can be seen from his performance in the early part of the sprint race. He didn't feel there was anything wrong with the car even when he was chasing all the way.

But in the later stage, Qin Chuan's car's grip was sometimes good and sometimes bad, which made him nervous when turning.

After returning, John found the cause of this problem. The problem was with the tire pressure.

Tire pressure, that is, the air pressure inside the tires of the front and rear wheels, is crucial in the race and can affect the driver's performance and grip.

In simple terms, tire pressure is the amount of air pumped into the tire. The more air pumped into the tire, the harder the tire and the greater the internal pressure. On the contrary, the less air there is in the tire, the softer the surface. This is the tire pressure.

His car tuning increased the temperature of the car's tires, increased tire wear, and the rate of increase in internal tire pressure continued to rise.

Tire pressure is something that greatly affects tire grip. Anyone who has raced on the track knows that the tire pressure should be lower when racing on the track than when commuting in the city.

One of the reasons is that when the tire pressure is low, the tire will deform. This deformation can increase the tire's grip. For example, if a sphere is very hard, then the area it contacts with the ground will only be one point, but on the contrary, if it is slightly softer.

Then, under the influence of weight, the sphere will deform slightly, which will increase the contact area with the ground and thus improve the grip.

Therefore, in order to increase the tire's grip area, the tire pressure for racing will be lower. This method is not suitable for driving in urban areas, because too soft tire pressure can easily damage the wheel hub when passing through some gravel roads, and it is also inconvenient to carry passengers.

Another reason why the tire pressure on the track is low is that the track requires intense driving, especially in a race like GP. The tire temperature often remains around 100 degrees in the later stages, so it is no problem to use it for cooking.

During the race, tire pressure will gradually soar as the temperature rises. The so-called thermal expansion and contraction is very applicable to tire pressure. Qin Chuan's racing problems mainly lie here.

His tire pressure was very low in the early stages, almost at the minimum tire pressure requirement of the race, but the tire pressure was very high in the later stages, causing him to lose some grip.

This stems from his tuning problems. His car tuning will accelerate the temperature of the tires and increase the tire pressure more quickly. This part of the tuning stems from the core Stoner part.
