[改裝實戰] 0-100km/h: 8.35 seconds (Part 1)Honda HR-V Turbo transformation

vehicle/Wide name turbo

The improvement of the power and speed of the car has always been a car change plan pursued by many enthusiastic men. After all, for them, driving is not just about moving from point A to point B, but also hopes to have more fun in the process. Exciting, and because of this, the owners of this Honda HR-V will seek the opportunity of turbo transformation. After going through a lot of challenges, they finally realized this plan a few days ago, so that the car has a reborn acceleration performance.

R18A engine with external turbo

The overall structure has not changed much

Although the Honda HR-V is a moderately sized SUV model, although there is still a certain amount of sales in the domestic market, it was originally expected to be equipped with the same 1.5T as the fifth-generation CR-V when it underwent a minor facelift in May 2019. The earth dream engine, but such an idea has not been realized in the end. Taiwan Honda still uses the R18A engine that has been published for many years in the power system. Of course, in terms of fuel consumption performance, maintenance costs and car manufacturing costs, the use of R18A is The right choice, but for owners who love speed, there is no strong power to drive.

Taking this small facelift HR-V as an example, the original power data is 143hp maximum horsepower and 17.5kgm maximum torque, and the transmission system is Earth Dream's CVT stepless gearbox, foreign original 0-100km/ The acceleration performance of h is about 10 seconds. Generally, it is enough for daily life and can meet the needs of 70% of car owners. However, if you want to have a more agile acceleration force, you may not be able to achieve it, and if you want to increase the speed To increase the power output by a wide margin, adding a turbo system is the fastest and most effective way, so this HR-V Turbo was born.

The store that installed the turbo kit for this HR-V is Guangming Turbo located in the middle. It has very rich experience in the modification of the R18A external turbo system. According to the store, the R18A engine structure carried by the HR-V is similar to The Civic 8/9 generation 1.8L models are not much different, including the intake manifold, exhaust head section and software system, all of which are almost exactly the same, so the hardware modification is not difficult, such as the most important exhaust head of the external turbo Section and Down-Pipe section, you can directly use the products developed for the Civic 8/9 generation in the past, and this exhaust head section still retains the installation hole for the first oxygen sensor, and the Down Pipe can also be used. Reinstalling the original EGR exhaust gas recovery pipe is a fairly complete set of products.

Although there are similarities, there are also differences. For example, the tailpipe after Down-Pipe is completely different from the Civic 8/9 generation, perhaps because HR-V has AWD drive models abroad. , so the middle exhaust pipe is not arranged straight to the rear of the car, but is first wound to the left side of the vehicle, and is discharged under the rear seat to the right side of the rear of the car, so when modifying the middle tail exhaust pipe, it takes a little effort After several revisions, it can be ensured that the exhaust pipe will not be stuck to the car body or suspension system after a period of time due to thermal expansion and cold contraction, or due to factors such as reducing the height of the vehicle. The exhaust pipe adopts the design of full straight-through + exhaust valve, which can take into account the quietness of long-distance driving and the smoothness of exhaust during intense driving.
