As two generations of 5-series F18 and G30 players, let’s review the past few years.
From being nothing, I gradually became the top experiencer in my circle.
You can think of most of the vehicle and machine repair problems, I can name one or two.
Sure enough, BMW is a good car, training every amateur player to the direction of machine repair.
The growth and harvest are indeed not small.

Pay homage to the N20 era that was once far away

The first car is the 17 F18 525Li. At the beginning, this car is a more cost-effective choice, the price is relatively reasonable, the need for comfort configuration. Compared with the 3 series, the 5 series is more calm, the sense of strength at the rear and the broad rear row are full of inclusiveness. Inclusiveness means that this is a car with a wide age range for drivers, and people of all ages can find the parts they want on the body. It is usually a family vegetable shopping cart, which is suitable for business. I have to say that the matching of the ZF8 AT gearbox and the N20 was really outstanding at the same level, without the worries of Volkswagen’s double clutch and nervous gear shifts, nor the slowness of Mercedes-Benz. The emergence of power tends to be smooth and comfortable, and it can provide a good driving experience when you want to exercise, which is not very fast, but it is enough to make people feel satisfied. Most importantly, although it is a medium-power model, the N20 medium-power engine and high-power hardware and transmission are consistent. In fact, the data of the original factory 218Psrec 310Nm is very good every day. But it is true that it is not an express, at least in terms of flexibility. Slowly enter the pit from the appearance to the interior decoration, and finally to the power, watching other people’s cases to learn from experience, slowly moving closer to the M direction. Take the athletic route.

To commemorate the first time on the operating table.

Like many people, start from the appearance. Surround, hub, brake, interior, to power, exhaust. Is defined as a person who walks on the edge. After experiencing the recommendation of the insiders around me, the program changed several times, but did not run out of ideal results, and finally saw the case of cylinder explosion of the 28i high-power model, sounded my alarm, the hardware can not keep up with nothing. Many people look at the N20 high and low power similar things, such as piston compression ratio is different. There is a difference between the transmission shaft and the half shaft of the transmission system. But the most direct impact on the power performance is the engine belly parts. The forging upgrade of the piston connecting rod is the core, followed by larger turbines and smoother exhaust. This is going to happen step by step.

The masters disassembled step by step, and during the disassembly and disassembly, they also found that the aging of many rubber ring seals led to slight oil leakage, and there were also a lot of carbon deposits in the engine inlet, and many problems appeared over the years. This time, they all replaced it with new accessories and had a major operation.

In addition to the atmosphere lights, the interior features BO central horn, M LED steering wheel and M5 meter to add a little psychological horsepower. In addition to the extra comfort of alcantara in winter in the north, the small LED screen on the top can pay attention to the temperature of oil and water at any time.

The wheel hub is a home-made Daika custom-made 666m with snow tyres, because it is really difficult to drive in the north after it snows in winter. The appearance of the MT encirclement makes the overall style of the car on the road. When it is cold to get off the car to check the tire pressure, it shivers. Think about the cold. The background picture is in the BMW parking lot of brilliance in Shenyang.

The story of F18 is set aside. Today’s protagonist is the G30 525iM mentioned at the beginning of this year.

G30 525iM pick up car

The new car was marked, and I was more or less excited because there were many pieces waiting for it at home. Look forward to its change.

My obsession with the 5-Series is like the fanaticism of many friends around me on the 3-Series, from E46 to E9X to N54, to F30 Jump 04, to G chassis. As soon as G30 was launched abroad, I paid special attention to it. In addition to the interior reversal, what attracts me most is the appearance. In addition to the power sense of detail, the M sports suite car looks even younger. Different appearance kits give people with a wide range of ages more choices. Although the new car’s B48 engine is low-power, but bought a short-axle model is to improve the performance. The daily fuel economy is really much better than the N20, and it may also have something to do with the upgraded gearbox. This time, in order to run the straight-line acceleration race, the G30 lost a lot of weight, and the B48 cylinder block is stronger than the N20, which brings up the short-axis imported 525iM.

The license plate must also be renewed and inherited directly from F18. Appearance slowly to the base, after the brand came back the first thing to install the MP front lip, the first to get on the car modification, the car arrived before the accessories.

The 95 ethanol oil in the first box of the vegetarian car, most of the oil in the northeast is ethanol oil, because this gas station has only 95. So we just have to mess with it.

Wheels at the beginning or because of cost-effective (actual financial difficulties) choose domestic 20-inch BBS REV7 engraving forging. The quality is relatively reliable, and the color is DB gun ash. The whole thing is good.

The snow-capped mountains are big and simple. The 20-inch hub adjusts to a flush height with KV V3. The chassis adopts 55 bushings and connecting rods, which maximizes the handling ability without affecting the comfort, and makes the daily street more flexible.

Carbon fiber panels produce high contrast on white and highlight the level of movement.

The tail wing is equipped with domestic carbon fiber MP model.

The rear wheel has temporarily upgraded the CZV enlarged ventilator.

Advanced large turbines prepare for F4W

For a long time, I thought B48 had a lot of potential, but we didn’t find it anywhere, and even the result was not as good as that of N20. After changing several programs, they all ran for less than 6 seconds. Two turbines have also been replaced. At the beginning of the replacement of the turbine due to the exhaust side did not increase, is the so-called domestic processing “heart-to-heart turbine”. The intake efficiency is very high and the exhaust side port is very small, which leads to the connection between the turbine and the engine as a whole into a high-load pressure cooker, and the performance is naturally not fast. The G38 long axis 5 series of other programs is near 5.6with one step, and I have been staying in 6.xx before. Later, I learned about the TMC program, and the communication results of friends who have been brushed are very stable and fast. B48 riders in Chongqing, Shandong and Liaoning all report that the car is easy to drive. Then just one step in place, the need to change all changed, after all, want to get a place through the competition, a dream come true.

The first one to replace is the 100mesh header segment of mach5. It is said that this header segment is very good. Install one to try the effect, ah, feel sorry for the money.

It is true that the oil and gas separation mechanism of B48 engine is not good. After a long time, there will be a certain amount of sludge in the original turbine tube, and this phenomenon becomes more and more serious with the increase of mileage. The problem can be solved by adding an oil breathable kettle. At present, what we can know is the CR breathable kettle and the price is very conscientious. The bracket is fixed at the top of the shock tower, almost the original position, and there is no need to look for additional fixed points. I like the original installation very much, more or less obsessive-compulsive disorder.

Increase the pressure to install the CR oil breathable kettle, completely solve the problem of poor oil and gas separation of B48, if you do not install it, you will find that there will be oil residue in the turbine line.

After the installation of a large turbine, of course, it is necessary to increase the intercooler. The intercooler body of B48 is integrated in the intake manifold and uses coolant circulation to dissipate heat. Such being the case, increasing the volume and heat dissipation area of the coolant tank can effectively ensure the stability of the intake temperature. In theory, there is nothing wrong with saving interest. Various brands of CSF,WT,CR on the market have launched an intercooled radiator of B48&B58. After comparing the price and actual product parameters, it is found that SpeedTune, as a domestic brand, has a good performance-to-price ratio, because BMS can see the change of intake temperature in the app of the mobile phone. After the installation, I negotiated with the shop owner to withdraw if it didn’t work. Finally, when the outdoor air temperature was 30 degrees Celsius, running from static to 160, when the turbine was at full pressure, the screen recording of the phone showed that the air intake temperature gradually dropped from 57 to 38 degrees Celsius. I am quite satisfied with the result.

Snowtech 76mm enlarges the turbine tube, ST400 enlarges the turbine with TMC basic program, BMS wine spray and BMS plug-in, step by step to improve their ranking at the end of the car.

At that time, the TMC ZF8 gearbox program came out, and there was remote OBD brushing and writing. For the sake of grades and better response speed of the daily driving gearbox, the feeling of vomiting in BMW’s second liter and third gear was solved, and this detour did not go.

After looking for a lot of chassis reinforcements, I finally chose the M5 original car body rear axle chassis reinforcement beam, and I got the chassis kit myself. When this thing is fully loaded into the basement and the normal corner, it obviously feels that the butt of the car is more tight and there is no extra twisting and floating.

Overall, the side effect is still very OK.

After the masters finished disassembling and assembling, I wrapped all the wire harness and intake management with a “silver mask” myself, mainly to prevent the engine thermal radiation from affecting the intake temperature. In this way, the temperature in the tube is more constant when the wine is sprayed. With the large and medium cold of SpeedTune, the drying is done, and the actual test inlet temperature is improved a lot.

The turbine tube and the wine spray pipe are also insulated because the real temperature in the engine cabin is too high. I am afraid that there will be problems with the aging of the pipeline. I ask the master to do some details little by little, and I tell him what to do. Haha, thank you for your patience in installation.

I really can’t stand the original xenon headlamp. I changed the LED spoon lamp a month before the competition. The original angel eye was laid off, which really affected the temperament. Haha.

Driving on the Qipanshan road, I stopped by the side of the road to take some photos. As I am not a professional photographer, I can barely take a look at it. Haha, the back end of the car is very round but does not lose the details. I did not make the KWV3 shock absorber too low, because the road here will always surprise you. No, no, no.

In May, I took part in the shooting of the Shougang track in Qinhuangdao. This event was organized by Big Brother Nange. I drove all the way from Shenyang to Shougang. I felt a lot when I got off the track for the first time. Next time, I will write down the experience of the track.

After repeated performance tests, it has been proved that the tire wall of the rear wheel must be thicker in a straight line, 20-inch street walking is OK, but it is not possible to change the CUP2 in the running race. So we customized a lightweight 18-inch BBS RID style in r, which is very similar to STAR FKS, but it weighs as much as 6.8kg, which is great. The next step is to empty the unnecessary weight of the car before the race, adjust the tire pressure and get ready to do it.

I simply took a picture to commemorate that I spent money again.

The semi-hot melt grip effect of R888 is still very good, but the tire temperature requirement is too high.

378 brake disc can not install 18-inch wheels, had to mercilessly remove the 9660 and large disk, did not modify the brake wheels have lost their soul.

To be honest, the G30 had lost a lot of weight. As soon as the seat was removed, I was ready to take off to see what good things I had in my trunk.

F4W creates the record of the fastest G305 series

In this race, there are a lot of friends playing with cars and running together in a group, all of whom are TMC riders, which can be regarded as a small party for BMW.

I don’t know if I have to start with a group of photos and show me a rare opportunity.

Everyone’s modification needs are really different, as well as the appearance of the original factory.

Everyone is waiting for the race, communicating with each other how to run, how much ejection, how much tire pressure, how much alcohol, how many additives have been added, has always been these topics, because many people participate in the Shenyang F4W competition for the first time, including myself, very nervous, ah, afraid of not running humiliating,

For the sake of this competition, the front wheel is also specially restored, and it is still a flat tire. I don’t know if it will be a drag.

Posted a logo red font, festive.

The final time of running 01 was 4.79 seconds, which was my personal fastest record. When this result came out, I was a little confused, and very few BMW 4-cylinder engines could run this result.

This time in the ignorant circle.

After several tests, the results are very stable, exceeding the expected results are very satisfied with me,

By virtue of ET8.334, F4W0-200took the second place in this category in the morning and was refreshed by ATS in the afternoon, which is really reluctant, but I am still very pleased to refresh my own results. It can be said that the long-standing investment has paid off. At present, it should be the fastest B48 5 series in the country. I don’t know if there are any cyclists who are faster than me. This race is underprepared and lack of experience. I have learned a lot from the operation preparation work of the gods.

There are some errors between the test results and the race. Due to the tension of the first race, I was too busy to upload videos in time. It was too difficult to watch the lights and watch the video at the same time.

This picture record shows how I got faster step by step. I paid a lot in the early stage, and only I know the bitterness.

For a long time, I slowly moved from 6.x seconds to 5.x seconds, and now my score is stable at 4.x seconds. Only you can understand the long shunting road.

The results were uploaded by the car, G30-525i can be regarded as approval.

Brother Yu achieved good results in this competition. The autumn wind in Shenyang is biting cold. Everyone stood together, the excitement in their hearts and the rewards of long-term investment brought the distance between their hearts closer. Being a brother means doing it! Only they understand the way to change cars…
