Chapter 540 540. Vulnerable

Many drivers who have driven a turbocharged car should have heard of the term turbo lag.

What this means is that when the accelerator is depressed, the engine just roars and won't go away, because it takes a while for the turbo boost pressure to reach its maximum value.

During this period, the power of the entire vehicle can be roughly understood as the original displacement without turbocharging. For example, for a car with a 1.5T displacement, before the turbine is involved, the power is only equivalent to a 1.5T naturally aspirated car without the T at the back.

This is why many people don't like turbocharging or supercharging, but prefer the confidence of large displacement.

It is because a large-displacement self-priming performance car gives you a linear power experience, and you can experience the powerful feeling of large-displacement acceleration from beginning to end. Rather than in the early starting stage, I always feel that it is almost tasteless, and the motivation is weak and strong.

Compared with the converted 2.6T twin-turbocharged power of a rotary engine, the 3LV3.2 engine of the BMW M6CSL can be regarded as a large-displacement multi-cylinder self-priming engine.

Although in terms of absolute horsepower value, Xu Jia’s Mazda FC modified to 370P is not inferior to the BMW M3’s 343P. But in the initial stage, turbocharging has no advantages. It can even be called a disadvantage without establishing enough turbo pressure!

Not to mention Dongzi’s BMW M3, which is equipped with an SGM sequential gearbox that is rare among civilian performance cars. In terms of shift time and transmission efficiency, it can theoretically outperform traditional manual gearboxes in seconds.

This is why Dong Zai is so frivolous and confident. The car is better than the other person's, and the mountain roads are better than the other person's. Why should the car washer follow him?

"Three, two, one!"

As the driver's arm waved down, the BMW M3 in front of the car rushed out with a kick of oil on the floor. The advantage of the car's lightness and the transmission efficiency of the gearbox was instantly revealed. Even though Xu Jia behind him started at a very fast pace, it was still obvious that the distance between the two cars was widened.

"It's a pity that Xu Jia's starting speed has been left behind. Hong Kong Aberdeen does have some strength."

After Li Wenfeng saw Dongzi's advantage at the start, he said something regretful to Qin Hao beside him.

As the captain of the team, he basically drives all kinds of performance cars, not to mention classic performance cars like the BMW M3.

The ejection starting speed of Xujia Mazda RX7 is already at the limit, but the BMW M3CSL naturally has a starting advantage. This is a gap determined by the physical properties of the two cars.

But in a sense, it does mean that Dong Zai has two tricks. With Xu Jia's starting speed just now, if it were an opponent with other weaknesses, even if he had the advantage of the car, he would not be able to open up the gap with Xu Jia.

But as soon as Li Wenfeng finished speaking, the slight gap opened up by the BMW M3 at the start was instantly tied by Xu Jia. Going down the straight from the parking lot at the top of the mountain, before entering the first turn of the mountain road, Xu Jia's RX7FC was already almost touching the rear of the BMW M3.

The appearance of this scene caused a look of shock on the faces of the underground riders in the parking lot at the top of the mountain.

There is actually no power lag in the twin-turbocharger. Can the turbo pressure be fully increased from the start?

"It's too strong. This time I can confirm that Xu Jia is definitely at the level of a top professional driver!"

Qin Hao took a breath and replied to Li Wenfeng.

Many low-level underground drivers may have just seen Xu Jia catch up with the BMW M3 at the start, but they don't know how he overcomes turbo lag. But Qin Hao knew very well that when the throttle was pushed to pull the speed before starting, Xu Jia was actually building pressure on the twin turbines to ensure that the turbines could fully intervene immediately after the ejection!

The principle sounds simple, but the actual operation requires a demonic level of control over the speed and throttle. Otherwise, if the throttle is dry blasted, when the turbine pressure reaches a certain critical value, the pressure relief valve will activate to reduce the pressure in the intake duct and prevent damage to the throttle valve or bursting of the intake pipe.

Xu Jia needs to build enough pressure on the turbine, but he cannot pass it. The balance point can only be controlled by absolute personal strength!

Dongzi in the BMW M3 had a mocking smile on his face when he was leading at the start. But when he looked in the rearview mirror again, the mocking smile on his face froze.

Are you catching up now?

Dong Zai’s mind is filled with incredible thoughts. He has run countless mountain races over the years. With the advantage of the BMW M3, he is almost always unfavorable in the starting stage, even when facing mainland professional drivers!

Dongzi also knew that Xu Jia's car had been modified, because the exhaust sound was obviously different from the original one. But on mountain trails, horsepower has never been the decisive factor, especially when running down the mountain. In theory, two hundred horsepower is enough.

Even if the car washer's FC is modified to produce thousands of horsepower like a GTR, it can't be faster than him as long as it starts with a turbocharger!

Reality gave Dongzi a slap in the face. Not only did he not get rid of the gap with Xu Jia, he was directly pushed to the rear of the car by the other party. Can anyone really drive an FC so fast?

The straightaway in front of the parking lot is very short, and we soon reach the first C-turn in Tianming Mountain. After all, Dongzi was considered a professional gunner and had run in countless mountain races, so he calmed down the shock in his heart and began to cut corners quickly.

"Young bird (rookie), if you have the ability, you can make corners faster than me!"

Dongzi sat in the car and muttered to himself ferociously.

The straight road may be the reason why the car washer behind him suddenly changed his horsepower, so the acceleration is faster. The curves are the home field of mountain attackers like him. He doesn't believe that Xu Jia can be faster than him!

At this time, Dongzi stepped on the accelerator and started to accelerate before entering the corner. After entering the corner, he released the accelerator and sharply cut the steering wheel. Without applying the brakes to slow down, the inertia is used to throw the rear of the car out and drift around corners. This is the most common inertia-drift on mountain roads!

Inertial drift is basically something that underground racers can do when running hills, but the control of the vehicle's sliding during the drift process, as well as the grasp of the acceleration period when downshifting and replenishing fuel when exiting corners, will test the driver's driving skills.

Dong Zai is very good at this. Basically, the entire drift process draws a perfect arc, just like the scene in the movie "Initial D".

If you were an ordinary mountain driver, facing this level of drifting, it would be very difficult to be better and faster than Dongzi.

But unfortunately, Xu Jia is not an ordinary driver, he does not drift at all!

Also facing a C-shaped right curve, Xu Jia turned the steering wheel to the opposite lane on the left, then stepped on the accelerator and headed straight for the APEX (center of the bend) point in the center of the curve, using the standard left-right-left cut. Cornering way.

Even at the apex of the corner, Xu Jia's speed on the speedometer was as high as 130km/h. Compared with Dongzi, who was drifting with inertia when the throttle was idle, the top speed was only 90km/h. The cornering speeds of both sides were not at the same level at all!

Just after passing the first corner of Tianming Mountain, Xu Jia's front can be said to be close to the rear of the BMW M3, waiting for an overtaking opportunity!

This group of Donghai underground riders on the top of the mountain, many people were looking forward to it before running. This might be a showdown between experts.

As a result, I did not expect that the masters were indeed masters, but their strength showed a one-sided crushing. Why did the top five mountain attackers in Hong Kong seem to be vulnerable in front of Xu Jia?
