Tomei Camshaft ProCam EJ25 Dual AVCS- Intake 272-10.80 (TA301C-SB02D)

Tomei Camshaft ProCam EJ25 Dual AVCS- Intake 272-10.80 (TA301C-SB02D)The Procam is designed for large turbo setups and high rpm use, making it ideal for drift, track and drag applications. The profile of these camshafts were designed to aim for maximum efficiency of the valve opening and closing duration.

The Procam is designed for large turbo setups and high rpm use, making it ideal for drift, track and drag applications. The profile of these camshafts were designed to aim for maximum efficiency of the valve opening and closing duration. These PROCAMS were designed with a quicker valve opening time and a gentle closing time to provide stability to the valve seat rings. This lightens the stress applied to the all the surrounding components of the valvetrain and decrease unwanted noises.

Each and every profile with varying duration and lift listed below are designed to perform the best during 4,000-10,000 RPMs.

By utilizing the combination of the best strongest raw materials and the leading CNC camshaft grinding machine in the industry, Tomei has managed to create a camshaft of the highest in quality and accuracy down to the last micron unit.

Features:

• High spec profiles for professional tuners /applications
• Designed for high power setups
• Requires high-performance valve springs
• Optimized 'velocity' and 'acceleration' Higher lift than other profiles of the duration.

The general purpose of engine tuning is to change the torque characteristics of the engine by changing the cams duration timing and cam lift amount for maximum torque and horse power. However tuning the engine is not only based on that. When going into finer details by maximizing the Valves efficiency is not just about timing and height lift but to also maximize the intake efficiency. The high valve lift allows huge amounts of air in but at the same time it mechanically damages the valve train and gains added friction loss. Longer cam durations and big cam lifts give deliver more power at higher engine speeds but it also gives a rough idle and at low engine speeds. Tomei engineers worked hard to produce camshafts that will deliver a well balanced profile at 1.3-1.5 times more than the stock camshaft.

Every camshaft is carefully built through these production processes. Plus, strict inspection will be given to them and only the highest quality products are shipped. Coating the surface of camshaft with manganese phosphate in order to protect from damage even when the camshaft has not lubricated yet. This has done by steeping press process that produces 0.5mm to 15 micromillimeter thin of manganese phosphate coating on its surface to prevent from direct contact with other metal parts while realizing smooth operation.
