Tomei began operations in 1968 as a race car tuner in Japan. Over the last 40 years Japan has emerged as one of the leaders in automotive research, racing, and culture. Tomei products have been utilized in nearly every motor sport imaginable. Tomei's racing heritage means their research and design team have first hand knowledge of the extreme demands racing puts on an engine. Using only the highest quality materials means that Tomei's products can handle the intense strain and heat a purpose built engine will experience whether it be on the street or the track. Tomei's attention to detail is second to none. All of their products are thoroughly researched and engineered to achieve optimal efficiency. Because of even miniscule differences in measurements can cause catastrophic engine failure, all Tomei products fall within strict tolerances. Tomei machines all of their engine components to enhance airflow and ensure proper fitment and seal.Adjustable up to 10 degreesEnhances look of engine bay with unique finish.Constructed of Duralumin and lightweight billet Aluminum
Fine tuning is the key to maximizing any engines power output. Seemingly small adjustments can have huge effects on an engines performance, behavior, and reliability. The Cam pulley is used to rotate the camshaft which in turn will push the valve down. The timing of the valve depends on the positioning of the camshaft and the cam pulley. If the valve comes down before the piston reaches top dead center, the timing is considered advance. If the valve comes down after the piston reaches top dead center, it is considered retard. The adjustable cam pulley allows you to change the valve timing which is normally fixed. This is similar to a variable valve timing system except the timing on variable valve timing engine is variable depending on engine speed and changes while the engine is running. An adjustable cam pulley can only be set at one position/angle and can only be changed when the engine is not running. Changing the timing means peak power will be reached at different engine speeds. This allows you to calibrate your engines power band to your individual driving style. Tomei camshaft pulleys are made from lightweight Duralumin and Aluminum. These materials are an ideal choice for their lightweight and durability. Tomei camshaft pulleys are anodized to dress up the engine bay.
Rated up to 1000 HP and 10,000 RMP
Mr. Seiichi Suzuki initially forged Tomei is a tuning factory for race cars back in 1968. From that day on, Tomei achieved excellent results in various motor sports categories. Tomei was then recognized for its technology, performance and reliability that we had cultivated into our own design products and had a large support base from motor sports end users and tuners.
With the new market trends and demands, motoring enthusiasts wanted better performance to suit the new modern lifestyle. This trend helped set the stage where originality can play an active part in the motor sports scene and personal motoring lifestyle.
