Tomei Poncam EJ25 Camshaft Set 254-10.30 (06-14 WRX, 04-07 STI)

''VALC' profile features- Velocity, Acceleration, Lift, Control

  • Optimized 'velocity' and 'acceleration'
  • Designed for high power setups
  • Optimizes engine performance
  • Higher lift than other profiles of the duration
  • Reduced stress/wear on the valve train

The VALC profile allows the valves to open faster and for longer. This translates to faster lift and increased area under the 'lift curve' which in turn generates more power. (Greater area under the 'lift curve' = greater air intake)

With a conventional direct-acting valve train, the maximum lift is usually determined by the size/diameter of the valve lifter. Selecting a high-lift camshaft without taking this into consideration often results in the camshaft lobes travelling beyond the surface of the valve lifter. This causes the lobe to make contact with the edge of the lifter, damaging both components over time. Therefore, the ideal performance orientated high-lift camshaft needs to have a profile that maximizes lobe travel on the lifter without exceeding the outer edge.

VALC profile camshafts have achieved this ideal by deliberately reducing the maximum cam velocity to limit lobe travel on the lifter surface. (Maximum cam velocity = lobe travel distance on lifter)

High lift profile without taking lifter size/radius into account.

Compared to standard profile camshafts of the same lift, VALC profile camshafts are able to then then off-set the difference for even greater lift/performance gains.

Compatible with Variable Valve Timing
The camshafts work together with the factory intake variable valve timing for noticeable performance improvements across the range

Reliable Lubrication
Optimized oil feed hole diameter and design ensures a steady flow of oil to the journals.

Specially Made Lightweight and Durable Cores.
Specially made robust hollow cores for a lightweight yet highly durable camshaft.

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. Then the “TOMEI” brand was born through experience.

Pour the power technology in the race experience in product development in pursuit of low cost and high quality in basis to provide the name of the product called technology ….

We achieve this mission, is willing to work hard in the future to meet the expectations of motor sports enthusiasts.
