The change of knight errant to golf R20.

Domestic golf GTI is the most successful civil performance car in China, but Polo? Forget GTI. And higher than GTi is the R series. Golf r series, born out of the fourth generation of golf, started the turbocharged version EA 1 13 in the sixth generation, and Borg? Warner's K04 turbocharger has an output power of 256 HP (China version). According to the tradition that the R series is named after the displacement, the R series of the sixth generation golf is called R20. Dynoking Automotive Technology Research Institute is famous for refitting high-powered Japanese cars. When there were no successors for Japanese high-performance cars, Dynoking Automotive Technology Research Institute applied high-power modification technology to the golf R20, changed turbines and rewritten computers, and 500 horses were gone. Let's make do with 400 horses. If you think the change is too radical and tasteless, you can drive the original R20 without leaving. It doesn't matter. There is also a slightly revised version of Daily Street for reference.

In terms of appearance, both golf R20s are pure original. The sensitivity of Shenzhen law enforcement agencies to modified vehicles is the highest in China, with at most one vehicle. Many car owners have given up the exaggerated aerodynamic package and chose to use the original appearance, pretending to make soy sauce from the checkpoint in a low-key way. Fortunately, the original air force kit of Golf R20 is domineering enough, and the three barriers show surging momentum. The key is that the driving license is like this. So there is no need for shape modification. Let's lower the body. This is the best shape modification. The so-called "one low covers three ugliness", using hinge shock absorbers to reduce the height of the car body, making the car body lower and stick to the ground. R20 is already very powerful, so there is nothing to complain about.

Figure: The low cover covers three ugliness, and the whole wheel arch is the most beautiful.

What are the concepts of 256 horses and 400 horses respectively? Running on the road is actually the difference between easy overtaking and easy overtaking. /kloc-the gap of 0/50 horses should be put on the track, and the strength of 400 horses can only be fully exerted after the third gear. The boost value of 1.4Bar makes the push-back feel handy, and the acceleration force does not seem to be weakened by the accumulation of gears. On the contrary, when the compliant turbine intervenes, it feels like "stepping on more and more". Isn't it quick to modify it a little? If you have tried it, you will know that the power of reaction is not just digital horsepower. For the displacement of 2.0, the K04 turbine will enter the best state after 2500 rpm, and it will not be tired until 5000 rpm. This speed range can just cover the needs of daily occasional walking, and there seems to be no time difference between the depth of the throttle and the action of the pointer of the Pivot booster table pointing to the 0.9Bar booster value.

Figure: From the cleanliness of the engine compartment, we can see the difference between the two R20s in power modification, one is violent and the other is introverted.

How can the original K04 turbine satisfy the owner's appetite only with the boost value of 0.9Bar? So we found the 480 horsepower Owen turbine. Owen, a relatively unfamiliar name, may be more famous in WRC. A great deal of experience in OEM turbine for WRC racing car makes Owen Turbine eliminate the lag of large turbine in low-speed response, and the torque output is very smooth when accelerating. Only by pushing back from your seat can you know how violent EA 1 13 is at this time. It is said that the blades of the turbine body using ball bearings can be rotated by blowing with the mouth, which shows that the rotation smoothness is amazing. Without intra-abdominal reinforcement, this turbine can easily output the constant pressure of 1.4Bar and the instantaneous pressure of 1.8Bar. Thai computer technicians used Dimsport's adjustable computer to intervene the Bosch MED9. 1 of the original car. The ECU readjusts the working parameters of the engine. At present, before the engine is strengthened in the abdomen, the horsepower output setting is relatively "conservative", and the estimated horsepower is about 400 horsepower.

Figure: Only the "simple and rude" GruppeM intake kit can be seen from this angle.

With the addition of turbines, this R20 is equipped with peripheral evolution components of the intake and exhaust systems. In terms of air intake, GruppeM large-flow air filter provides clean air for turbine block, and Forge air intake pressure relief valve allows high-pressure air to be discharged faster than the original pressure relief valve, which is the only choice to protect turbine blades and throttle valve after turbine pressure rises. The other part of Forge is the intercooler of Forge. The original intercooler of PQ35 platform is placed behind the water tank, and the air is blown to the intercooler after passing through the water tank, so the cooling efficiency is not high. Therefore, the front intercooler of Forge is placed in front of the water tank and connected in parallel with the original intercooler in a sandwich way, which greatly increases the cooling effect of the intercooler and makes the pressurized air have a better cooling effect, which can make the engine block bear a larger pressurization value and directly improve the engine output power without changing the compression ratio. In terms of exhaust, in order to ensure the smooth operation of turbine blades, the owner chose Milltek's full-face low-resistance exhaust to let the turbine run freely without overheating. But close to the sound of direct exhaust, it is better not to go home at midnight.

After the sudden increase in power, the first thing that is "implicated" is of course the transmission system. The clutch part of DSG gearbox has shown fatigue when dealing with the output that is 40% higher than the original 35.7Kgm. When the clutch needs to be re-engaged, such as reversing with a paddle or starting with a large throttle, the engine will slip for a short time because of excessive torque output, which will affect the power transmission efficiency. The refit shop said that the whole world also wants a set of DSG reinforced clutches, but we haven't found a completely satisfactory product yet, so we have to "take the lead". In addition, the 4Motion of R20 adopts Haldex's fourth-generation friction central differential, and the driving will focus on the walking characteristics of front-wheel drive. When the horsepower output is enhanced, the tendency of the push rod to bend will be more obvious due to the characteristics of leaning to the front wheel. Therefore, Haldex's central differential computer with a fixed distribution ratio of 50:50 was upgraded, so that the rear wheel can get more power, and the rear end can move outward more dynamically when cornering, which improves the characteristics of R20 itself.

A slight change in the golf R20 means that I won't fight with you. Because the owner usually uses it as a means of transportation, there is no core upgrade of power. Only the intake system of EA 1 13 engine is optimized, which makes the engine breathe more smoothly, the dynamic response is faster, and the daily driving is more handy. The scooter has 256 horsepower, which is actually quite enough. There are only two modification projects, namely, APR activated carbon fiber intake kit and Forge pressure relief valve. APR is an activated carbon fiber intake kit designed for golf R20. Its carbon fiber gas collection box is placed in front of the original air cleaner filter element, which directly sucks fresh air from above the air deflector in the front of the engine compartment to avoid inhaling high-temperature air in the engine compartment. The inhaled air has lower temperature, higher molecular density and lower combustion temperature, which is beneficial to horsepower and engine life. Forge pressure relief valve can be said to be a must-replace item for Volkswagen Turbo Car, which has faster response than the original pressure relief valve and effectively protects the turbine and throttle. Catching up on the mountain road and changing R20 lightly depends on the advantages of small turbine and quick response. In the case of short-distance acceleration and frequent cornering, it will not be thrown out by the high-power R20. On the contrary, because the throttle control is easier to grasp, you can boldly cling to each other in corners.

It seems that European cars don't like big interiors. On the one hand, it is the interior of European cars with strong integrity. On the other hand, maybe it's European culture, so it's not easy to add any foreign languages. Even if it is added, it will use some existing space in the car, unlike Japanese cars standing directly on the dashboard. The interiors of these two golf R's haven't changed much. On the one hand, Golf R makes the interior exercise enough. On the other hand, from the perspective of transportation, there is really no need to make them too fancy.

Figure: The corresponding Pivot booster value table runs counter to the usual red color of other brands' high-performance series, and the symbol of R series is blue pointer.

Run as fast as possible. Anyway, after fast, Endless's new six-piston caliper braking system makes R20 return to rational speed. Japanese brake brand Endless believes that even European car owners will not feel strange. Although the street has changed a little, the owner firmly believes that braking performance is very important for daily driving safety, and the fast car that can be retracted freely is a really reassuring good car. Therefore, even if it is only the original horsepower, I dare not neglect it. The owner replaced the iconic blue single-piston caliper of R car with a new ring brake suit which is also blue. The callipers cut from forged aluminum alloy have excellent rigidity, MX72 brake pads, extremely rigid callipers and AP? Racing? With a diameter of 355mm, the braking effect is reassuring. Is the Japanese car in Europe not authentic enough? I'm sure R20 owners will laugh at this view. Who knows the endless sense of overbearing feet? Horse brand SportContact2 can only start a lock-up protest with a half-foot brake. Replacing the front wheel brake and keeping the original caliper of the rear wheel to avoid the body center of gravity shifting to the front wheel when braking, and the braking force of the rear wheel is too large, which causes the rear wheel to lock and trigger ABS and cut off the braking force of the front wheel that has not reached the limit. This is actually a very wise modification method.

Figure: Endless's new six-piston caliper is different from the previous caliper design of the brand, lighter and stronger, equipped with 355mm APRacing brake disc.

Figure: There is a groove on the brake disc to discharge brake dust, and the head of the brake disc box also has a groove to prevent the brake disc from expanding with heat and contracting with cold.

As for the modified R20, the degree of power modification is directly proportional to the upgrade of the brake system. Power sword refers to the "magic car" level, of course, it needs a magical braking system to be fast and safe. Does the owner choose to go directly to AP? Racing competitive six-piston brake caliper Pro? 5000+。 AP？ The competitive series CP5060 calipers of the racing car are equipped with track brake pads, and the braking force can be said to be increasing. In other words, when the brake disc and brake pad are still cold, it is best to reserve a little more braking distance. When the temperature is high, the brake pad will get better gradually. By the way, you should also be prepared for the harsh noise when dragging the brakes at low speed. After all, if you want to use overbearing braking force to slow down the car to a safe speed in the shortest distance, the material formula of brake disc and brake shoe must be high friction and high temperature resistance, so it is acceptable that the performance is slightly inferior at low temperature and low speed. What's more, can you use the hot melt adhesive formula of MAHONEOVA? AD08 also likes a slightly higher operating temperature.

Figure: AP? Racing's competitive series does not emphasize fancy, but all show people with aluminum alloy primary colors.

In the selection of shock absorbers and rims, we can also see the richness and frugality of car modification. The street style takes the people-friendly route, and the collocation of BC shock absorber and Filota rim in Taiwan Province Province is only one R20 BilsteinB 16? PSS 10 shock absorber with Japanese rays? Less than half of C345 forged rim. However, whether visually or in actual handling performance, the difference between the two cars is not as obvious as the price difference, and it is only fulfilling the marginal effect of "a penny for a share, a penny for a share". The support force of BC top-class street shock absorber is stronger than that of entry-level model, but it should be because of the internal design problem of shock absorber, the damping response of shock absorber is not fine enough, and occasionally it will bounce slightly, so it is impossible to walk steadily with the body. By contrast, what about Billstam? The body dynamics of B 16 is similar, and the supporting force of the body is almost the same as that of BC when cornering, but the shock absorber has a more crisp ability to deal with fine jump. Both sets of shock absorbers are confident enough to twist the car body into a bending center and chase, run fast, brake and twist the steering wheel on the mountain road. The four-wheel drive system makes the tires in four corners compete with each other and controls the torque distribution of the four wheels when turning. Of course, even the most intelligent and high-performance four-wheel drive system in the world can better use up the limit of four tires, but it still cannot exceed the natural physical limit.

Figure: The rim should be fully supported and lowered. In this way, even if the wheel eyebrows are rolled out, there will still be friction when turning.

Two golf R20s belong to the category of express trains. Although there is a gap between the performance of the two cars, it does not mean who is better than who. It's just a matter of orientation. The high-powered R20 is guided by its suitability for venting passion in such a safe and open environment on the track. Whether it is the power system, the walking system or the braking system, it is composed of parts that are slightly higher than the high-performance parts on the street. Reasonable, fast and extremely balanced in all aspects. Whether it is accelerating or decelerating or cornering, it is worthy of being a master of the track. For the R20 with low output, the owner did not blindly pursue any big data, but started with the basic skills according to personal needs, highlighting the strengthening of braking performance and lowering the body route. Daily driving is handy, and the use cost is not as high as that of a high-powered car. The ideal state is to have two such cars at the same time, running the track with high horsepower and walking with small horses every day. Two kinds of pleasure, if you can have both, wouldn't it be quick?
