Tomei - SR20DET VALC Poncam Camshaft - S13

The development target for TOMEI’s camshaft PONCAM was “The new performance in all stages”.
Without giving partial character to the engine or relying on the setting after it is put on, it enables gaining power only by changing camshaft itself.
Not like the performance of wide angle-high RPM camshafts that gives special but partial character to the engine,PONCAM gives smooth output character and quick response which is required in today’s tuning scene.
It provides the performance of tuning camshaft in every kind of driving situation, though, it won’t make you feel stressful by falling into the unstable idle.

Tomei Poncams for all S13 SR20DET models. Because they are designed to be compatible with stock valve springs and 'bolt-on' type turbos, Tomei Poncams are the best drop-in camshaft solution for the SR20 powertrain.

Utilizing cutting edge VALC profile technology, the Poncam 258* camshafts combine the stable idling and low midrange of a 256* camshaft together with the top end performance of a 264* camshaft. In addition, they also feature the highest lift amount that's compatible with the stock valve springs for increased flow rate and higher power output.

Features:

• Pre-Set Valve Timing
• Stable Idling
• Compatible with Stock Valve Springs
• Noticeable Linear Power Gains
• Works best with 'bolt-on' type turbos

Specifications:

Intake

VALC Valve Lift Profile _{Velocity, Acceleration, Lift, Control}

The new 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' = increased air intake.)

VALC Features:

• 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 Valvetrain
  

The Best Performance for Drift Driving

As mentioned before, the development target of PONCAM was raising performance in all stages. In ‘drift’ driving, driver controls the vehicle’s sliding angle with a delicate accelerator work, and installation of POCAM enables ‘drift’ drivers to control the vehicle much easier with its sharp response to the input. Moreover, according to its better controllability, driver can raise the entering speed at the corner that succeeded in gaining sliding angle distance at the same time.
