Have you ever wondered about the term JDM when entering the car tuning world? It is short for Japanese Domestic Market, yet it represents far more than that. JDM has become one of the most influential tuning car trends that blends performance, style, and deep respect for Japanese automotive craftsmanship.  What is a JDM?The original meaning of a JDM refers to cars and auto parts that were built solely for the Japanese market. These vehicles/parts are built with unique specifications, trims, or features that are not available in export versions. However, in today’s tuning culture, JDM now represents an entire...

  Arashi has recently introduced a new iconic design combining Daruma with Arashi turbocharger. We’ve chosen Daruma as the icon because Arashi shares the same value as its spirit. The Daruma doll is known as one of Japan’s most popular talismans, symbolizing perseverance and good luck, and representing persistence and realization of your dreams. The doll usually has round shape, bold facial features, and signature wide-open eyes.  History & Origin of DarumaA Daruma doll is a Japanese traditional doll modeled after Bodhidharma, the founder of the Zen tradition of Buddhism. Bodhidharma was a princess who became a monk and is...

Turbocharger is one of the engine parts that enhances power and efficiency without increasing engine displacement. Among various turbocharger designs, we’re doing a comparison between single scroll and twin scroll turbochargers since they’re more common on the market.  A turbocharger works when exhaust gases from exhaust manifold propels the turbine wheel and jointly drives the compressor wheel to spin and compress air into the engine for greater power.   What is a Single Scroll Turbocharger? With single scroll turbochargers, exhaust gases from all engine cylinders feed into a single inlet housing (spiral chamber), these gases spin the turbine and propels...

Turbocharger surge is an unstable aerodynamic condition in a turbocharger compressor when there is a disruption in the balance of airflow through the turbocharger. This imbalance causes a rapid reversal of airflow in the turbo compressor, leading to unstable operations like oscillations and distinctive fluttering noise. If such conditions remain, it may reduce performance and potentially cause premature turbo failure.  Causes of Turbocharger Surge 1.      Operating Outside the Compressor’s Stable Map Region － Low Mass Flow Condition: When the engine is running at low load or during rapid deceleration, the airflow through the compressor may drop below the optimal range of...

Turbo oil leakage can result from a variety of factors, in this discussion we’ll pick 5 common factors for oil leakage – clogged air filter, poor oil return, leak in the exhaust system, increased crankcase pressure, and a collapsed turbine piston ring. A turbocharger should not leak oil under proper installation; however, oil leaks may lead to catastrophic damage to the bearing systems. Clogged Air Filter An air filter keeps dirt and debris from entering the engine. A clogged filter can lead to several problems, impeding the engine to work properly.  Cause: A clogged air filter restricts airflow into the...
