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

As Qin Chuan's car drove out of the P room, the staff, technicians, and engineers of the KTM team all came to the instrument.

Today is the only track open day before the race, and the car tuning for tomorrow’s race must be completed within today.

On the track, Qin Chuan drove the latest rc16 and accelerated wildly. The roar of the exhaust and the noise of the wind were transmitted to Qin Chuan's ears along the helmet.

From the moment he drove this car on the track, he felt the difference between this car and his previous satellite car.

It was very subtle, but he was still keenly aware of it.

The most intuitive slight feeling on the straight line is the improvement in rear wheel grip.

No matter what kind of car it is, the tire temperature has not completely risen after it leaves the P room. In this state, the rear wheel of the car has slight slip. On this car, the rear wheel slip is smaller than that of the previous satellite car. .

The appearance has not changed, but it seems that the frame has changed quite a lot, especially the swingarm connecting the rear wheel.

This is the key to determining the grip of the rear wheels of the car.

The grip of the rear wheels increased. This car was definitely faster in a straight line than his previous satellite car. He kept his eyes fixed on the front. Turn [-] was about to come. Qin Chuan did not think about it anymore. He believed that this car gave him There will definitely be no less surprises than you expected.

The car turns into an orange straight line in the camera.

Before the first turn, Qin Chuan reached a tail speed of 344km/h. For a straight line with a length of only 0.8km/h, this tail speed was undoubtedly very terrifying.

At the braking point, Qin Chuan held the front brake lever with his right hand and quickly downgraded five gears with his left foot. Sixth gear changed to first gear. He straightened his upper body, shifted his gaze from the end of the straight line to the center area on the right side of Turn [-], and tilted the body. Enter the corner.

After the engine sound changed for five consecutive times, the car's rear wheels came off the ground and landed again, then tilted the car into the corner.

When the car enters the corner, Qin Chuan's perception is fully open.

There was no difference in braking, even worse than that of a satellite car. Qin Chuan knew that this was a tuning problem, but the stability in corners really surprised Qin Chuan.

The cornering speed has not increased, but the stability is obviously one level better than that of a satellite car, which means that it can achieve a lower inclination angle and can fight to the extreme when fighting in corners.

The orange racing car flew along the apex of the bend, and Qin Chuan's elbow joints rubbed gently against the ground.

The car reaches the center of the corner, and then exits the corner. Press the button with your left hand to lock the front shock absorber, and then turn on the gas with your right hand. With the help of the gyroscopic effect, the car gradually becomes upright and begins to exit the corner.

The increase in rear wheel grip also slightly improved the cornering speed. Qin Chuan dared to use the accelerator vigorously. From the corner speed of 140km/h, when the car body was completely upright, the vehicle speed had reached 210km/h.

After trying curves and straight lines, Qin Chuan also gained a new understanding of the upgrade of this car.

It is stronger than the old model in both curves and straight lines. Although everything is very slight, these slight improvements in GP are the key to victory.

But don't be happy too early.

In addition to these two places, Qin Chuan did not know about the tire eating situation of this car.

Tire eating is the speed at which tires are consumed. If this car does not increase the tire wear rate after the rear wheel grip is improved, then it is a top-notch car.

If the tire wear rate increases, the advantages brought by the previous items may be weakened.

There are many factors to consider when improving a racing car. You cannot draw conclusions just by looking at the final straight-line speed. Otherwise, with the R&D investment of Benda and Yamaha in recent years, they would have been able to catch up with Ducati on the straight line.

When it comes to the horsepower that an engine explodes in a straight line, one of the factors to consider is the wheel horsepower.

Wheel horsepower refers to the real horsepower that the engine exerts on the track through the frame, chain and rear wheel transmission, rather than the crankshaft horsepower inside the engine.

No matter how much the engine is improved, the rear wheel supported by the frame cannot provide much grip, and the horsepower on that wheel will decline.

Therefore, to improve the car, we must consider these two factors. After these two factors are resolved, there is a third factor, which is tire eating.

The increase in rear wheel grip will accelerate the wear rate of the rear wheel tires. If this is not controlled well, it will lead to weakness in the rear wheel. The rear wheel tires will be worn too seriously, which will lead to serious reverse upgrades in comparison with the overall speed.

When these three factors reach a balance point, the truth is to improve the straight line speed of the car.

This is why after Ducati’s power improvements in recent years, the other factory teams have had a hard time following suit.

Not only did Yamaha and Benda invest a lot of money, they even hired the engine consultant from F1 Ferrari next door, which didn't help. If one of the problems in these three areas was not solved, the car would not be able to increase its tail speed.

After running for thirty laps, Qin Chuan came to the conclusion that this car does not eat tires, but it does not save tires. It is similar to the previous old rc16, but the overall improvement effect is very good.

"How's it going? Are you still getting used to it?"

Back in the p room, John was the first to come up and ask Qin Chuan about his experience. Time was tight, and Qin Chuan did not waste time. He directly told the other party his most intuitive feelings, mainly some shortcomings, so that he could be trained and modified.

After collecting his feelings, John immediately went to deal with the car's problems, while Qin Chuan came to the instrument to check his lap time.

Feelings are feelings, the competition depends on data, and fast lap times are the truth.

At this moment Pedrosa also came up.

"Qinchuan, your adaptability is very good, but there is still a big difference between your lap time and Pentax. I will let Pentax go up and run with you later. You can follow him and see where your shortcomings are."

Pentax?

Qin Chuan thought of the Westerner about [-] meters tall who was in the p room with him before. He also went to the track and has not returned yet.

"it is good!"

Qin Chuan also discovered that his lap speed was much slower than that of Pentax. This was due to his lack of experience on this track.

When Qin Chuan came back, the ktm boss had already left. He had many things to do, so it was normal not to stay here.

After Pentax came back, the two took a rest, then got on the racing car and drove out of the P room again. Unexpectedly, this time Pedrosa also changed into a leather suit and followed them on Pentax's spare car. behind.

On the track, Qin Chuan followed Pentax, and Pedrosa followed Qin Chuan. The three of them were about five car bodies away from each other.

Pedrosa followed behind him, Qin Chuan's pressure also increased a little, and the speed of the car began to gradually increase.

At the same time, Qin Chuan also had the idea of ​​being curious about Pedrosa's strength.

One of the five legends of motogp who is only 158cm tall, what is his strength?
