[Refitting actual combat]Forging intra-abdominal Motec+ sequential gearbox (Part 2) Impreza STI (VAF) mountain climbing style

With sequential gearbox

After getting the output of the power system, the next step is the strengthening of the transmission system. In order to speed up the shifting speed and improve the power transmission efficiency, the car owner simply did not strengthen the original six-speed manual transmission, and simply replaced it with a Kaps Kotouc 6MT sequential transmission. In addition to the above advantages, the +ATS double-disc clutch can also strengthen the strength of the internal gears of the gearbox. There is no need to worry that the gearbox gears will collapse under the confrontation with the harsh track terrain and strong torque. However, with the sequential gearbox, how to configure the shift system is also very important. Tuner chose the Hydraulic paddle shift system. This set of shift systems adopts the design of hydraulically driven shift forks. Compared with the previous air pressure system , the pressure of the former to push the fork is more than 10 times higher than that of the latter. In addition to not having to worry about the forward and reverse gears, it can also get a faster shift response, and save more power, so it can be used without installing a large battery.

Almost all the interior of the car has been dismantled, leaving only the center console. There are also many shortcut keys on the steering wheel of the racing car. With the Motec computer, various functions of the car can be quickly set.

For the sequential gearbox to switch gears smoothly and effectively protect the life of the clutch disc, the key is to control the writing of the computer program, and this part is handed over to the Motec M150 supercomputer. According to Kenny, when the owner of the sequential gearbox presses the shift paddles on the steering wheel, the Motec computer will first determine whether it can go into or out of gear when it receives the designation. If the gear can be switched, it will execute the power interruption program. For example, the ignition is usually 100 times per second. At this time, it will only fire 60 times per second, so that the torque output of the engine will decrease, but the torque will not be completely cut off. The purpose is to allow the gear to be pushed in, and then Motec will give an order to Hydraulic to shift gears. The system starts to release the oil pressure to allow the transmission fork to perform the shifting work. After that, the ignition program will return to normal, allowing the power to be fully utilized. Such a complex process needs to be completed in less than a second, so the sequential shifting is required. When shifting gears, whether it can be smooth and at the same time reduce the wear of the clutch is a test of Tuner's skills. Fortunately, Kenny has rich experience in racing car tuning, so it is not difficult for him.

The Recaro Kung Fu Dragon racing chair provides excellent coverage and safety, and the fulcrum of the roll cage is less than expected, mainly to cope with the collision of the racing car. Too many points will increase the weight of the car.

The picture shows the Motec M150 main control computer and the Motec PDM30 power manager. In addition to the basic fuel supply and ignition adjustment functions, the former can also perform start-up ejection mode, partial ignition, automatic oil replenishment in reverse gear, and forward gear. Powerful function settings such as no oil collection and TCS anti-skid system control

When it comes to the Motec M150, a fully-replaceable computer, it should be recognized as one of the most powerful racing computers on the market. In addition to basic fuel supply and ignition adjustment functions, it can also perform start-up ejection mode and off-time ignition. , automatic oil replenishment in reverse gear, no fuel collection in forward gear, and TCS anti-skid system control. Opening control, actively reducing the engine power output when the vehicle slips, allowing the four wheels to regain grip For body angle.

At present, the maximum horsepower of this car is 423hp, the maximum torque is as high as 52kgm, and it has been fully output at around 4200rpm, which is just in line with the power requirements of the hill climbing competition. The transformation of the vehicle is quite successful.
