"Don't talk about these things that you don't have," Chen Geng scolded with a smile: "Hurry up and take me to see it...... How about the measured transmission efficiency of this gearbox?"

"Very good," after a pause, as if "very good" was not enough to describe the transmission designed by Mr. Fernandez, Anderson added: "Very good, we measured this transmission on a horsepower machine and the result is that this transmission has an actual transmission efficiency of 92.63%. ”

"92.63%?is so high?" Chen Geng was a little surprised.

According to Chen Geng's design, the transmission efficiency of this sequential gearbox is 96.5%, but limited by the materials and processing level of this era, Chen Geng's previous calculation is that 91.5% is considered good, even if this is a competitive gearbox that does not care much about the cost.

In fact, limited by processing capacity and material level, in this era, the efficiency of the transmission system is not very high, even if it is the most efficient manual transmission, the transmission efficiency on civilian models is basically not up to 80%, only about 75%, and the transmission efficiency of AT automatic transmission is even worse, basically hovering around 65%.

Why do American large-displacement cars use a large number of automatic transmissions, even if it is a 3AT with only three forward gears? It is not because the engine power of the old United States is large enough to be squandered and wasted: a 300-horsepower engine, even if the efficiency of the transmission system is only 65 percent, the final on-wheel power is still 195 horsepower, and the on-wheel power of 195 horsepower is not small in any way.

"The main thing is that your design is fantastic. Anderson smiled from ear to ear, as an automotive engineer, he certainly knows how much a well-designed, more efficient gearbox can help a racer in a race, and even a 1% increase in transmission efficiency can lay the ultimate advantage when two racers are at the same level and the car's engine performance is similar.

Chen Geng said happily: "Then what are you waiting for, hurry up and push the car out, I'll drive a circle and try it." ”

"Great!" Anderson was also excited, he was also very busy, and he was also looking forward to how the Corvette C3 with a 9.2-liter displacement heart would actually perform.

........................

In order to be more adaptable to the fierce competition, Chen Geng's Corvette C3 to participate in the Grand Prix has been strengthened in an all-round way, in addition to the power system, body structure, suspension system These key systems have been strengthened in a directional manner, Chen Geng has also specially lowered the body, no way, the original C3 chassis is too high, high can be used as a light off-road vehicle.

The engine exhaust system designed for high-speed use has not undergone any sound reduction and backpressure treatment, and the direct result is that the engine noise is scary, coupled with the huge working noise brought by the spur tooth design of the competitive sequential gearbox, resulting in this piece is all the roar of this car, and many customers who come to buy the car simply do not buy the car, and they come out to see the excitement.

When Chen Geng drove back, he was going to talk to Anderson about his feelings about the car and some details and directions that needed to be adjusted on the car, but before he got out of the car, the onlookers who ate melons enthusiastically flocked up, and Chen Geng's ears were instantly filled with all kinds of questions......

"Fernandez, is this car modified by you?

"Hey buddy, I also have a Corvette C3, but the sound of your engine is not the same as the engine of my car......"

"Dude, why is your car's gearbox so noisy? Wow...... You also have a roll cage in the car?"

"Dude, I heard that you modified this car yourself, can you help me get one?"

"Hey, hey, Fernandez, can we go and have a look at your tuning shop?"

"Dude, this devil's claw mark pattern on your gate is so cool, do you have any stickers to sell? I'm going to buy a few thoughtful ...... on my car"

This guy is obviously crooked......

............

Listening to this voice, Chen Geng was suddenly a little confused: Can anyone tell me what the situation is?

Thankfully, Anderson rescued him.

Seeing Anderson, who struggled to squeeze through the crowd and squeezed in front of him, Chen Geng asked loudly, "What's the matter?"

The surrounding environment was too noisy, and Anderson had to shout at Chen Geng: "Boss! These guys are very interested in this car we modified." ”

"That's it?" Chen Geng asked in disbelief, knowing that the American car culture leads the development and trend of global car culture, and no one can match it in car modification, which can be seen through dozens or hundreds of professional car modification companies and professional car modification parts manufacturing companies in Detroit, but the madness of these people is still beyond the limit of Chen Geng's imagination: how can they be so excited?

"That's it!" Anderson nodded heavily, looking at the doubts and incomprehension in Chen Geng's eyes, he had to say loudly again: "There are very few, many people who have never even seen a car converted into a professional racing car up close, so they are very excited. ”

I see!

Just like the Republic more than 30 years later, although the car culture and car modification culture have also developed to a certain extent, in the eyes of ordinary car owners, modified cars, especially professional racing cars modified to participate in high-level competitions, are still very mysterious in the eyes of ordinary drivers and fans: the engine that has been greatly strengthened and upgraded, and the competition ECU system has been replaced, the transmission with great noise but high transmission efficiency, and the suspension and suspension system that will not be damaged after flying and landing many times in a row......

Compared with the "straight king, corner death" modified by various private small workshops, the "civil science modified racing car" that sacrifices most of the performance to strengthen one or several aspects, and only knows how to "pile up" on the top, this kind of accurate calculation by high-level engineers, In the most scientific and reasonable way to carry out all-round strengthening of the car, all these things, can attract the eyes of car enthusiasts can not pull out, even the cage roll cage system designed by finite element calculation can make these car enthusiasts with a heart to become a racing driver for a while, and then pointed to the roll cage mouth like a river for three days and three nights......

So the reaction of these people at the moment is really normal, this is the normal behavior of car enthusiasts after seeing professional racing cars, just look at the FAW-Volkswagen CRC team held a public event, those fans gathered in front of the golf car, you can know that it is no different from these people.

Knowing what's going on, it's easy to do, Chen Geng shouted to Anderson: "Go, get me a megaphone!"

The loudspeaker was quickly sent to Chen Geng's hands.

Chen Geng stood on the hood of the engine, holding a loudspeaker and shouted: "Gentlemen, gentlemen, don't get excited, listen to me, I know what you want to do, it's okay, we will try our best to meet everyone's wishes, but for now, please be quiet." ”

The effect of the loudspeaker is very good, and Chen Geng is now standing on the hood again, facing everyone, these excited Lao Mei who are almost swinging down finally quieted down one after another, and they also realized that if they continue to make such noise, it is estimated that nothing can be done in the end.

Seeing that everyone finally quieted down, Chen Geng finally breathed a sigh of relief: "I know everyone is interested in this car, OK, I don't hide anything, this car is what we are going to use to participate in this autumn's modified car Grand Prix, this car is built by a number of top engineers from Ford, Chrysler and General Motors, representing the highest level of American car modification technology, I dare to say, if this car fails to win the championship in the end, it must be a problem with the level of the racer." ”

"Ha ......"

Lao Mei laughed in a group, although Chen Geng's words were obviously bragging, but Lao Mei likes to brag, and besides, this is not called bragging, this is called self-confidence in his own skills and level.

Chen Geng: "If you want to know more about this car and our modification level, it doesn't matter, I will arrange for the staff to organize a systematic visit to our racing car and the 'devil's claw' modification department, so that everyone can see our strength...... Oh, by the way, an advertisement, if you want to modify your car, you can also come to us, we will provide customers with a package of modification solutions according to the needs of customers, I guarantee that at the same price, our modification program must be the most competitive, modified racing must be the most in line with your requirements. ”

"Really?" As soon as Chen Geng's words fell, someone immediately shouted in surprise: "Mr. Fernandez, can we really visit your refitting workshop?"

"Of course you can," Chen Geng smiled and nodded, in any country's racing car modification industry, the real top tuning factories, are rarely allowed to ordinary people to visit, 75 years just established the world's top racing technology provider British Prodrive company, even racing drivers are not allowed to enter their own tuning workshop, these American car enthusiasts are also pitiful, even allowed to visit a professional racing car tuning factory are excited to be like this. But now, Chen Geng feels that this is a great opportunity to attract customers: "Not only can you visit, but you can also see a V12 forced air-cooled racing engine developed in cooperation with Honda Motor Co., Ltd., as well as our own competitive five-speed sequential transmission. ”

"Wow......"

Hearing Chen Geng's words, everyone was amazed, although they didn't know what the performance of these two things was, but they were very powerful things when they heard it.
