TOMEI ADJUSTABLE CAM GEAR EJ20 EJ25 SINGLE AVCS EX RH Supply

EASY VALVE TIMING ADJUSTMENTS WITH PONCAM

The Poncams valve timing has been preset at 110°. This Valve Timing has been calculated as the best setting for both performance and drivability. You can adjust the engines performance by making adjustments with the cam Gear carefully. This easy adjustable system is a great advantage over other conventional designs.

The engines output character can be changed just by re-adjusting the close timing over the intake valve as shown below.

• Turn Cam Gear to anti-clockwise (advanced timing): torque at low RPM
• Turn Cam Gear to clockwise (delayed timing): torque at high RPM

The standard Valve Timing is set to 0 on the scale. When you adjust the scale to + – 3 on the scale (3 degrees) that will be + – 6 degrees on the crank angle. The maximum range is + – 10 degrees on the Cam Gear which is + – 20 degrees on the crank angle. Please don t move the adjustable Cam Gear from zero position until the engine adjustment has been completed. If the cam Gear has been fitted without being setup on the initial key position then the engine wills not operate normally. If the valve timing has moved too much from the setting due to engine vibrations then the operation of the engine will get worse or in worse case scenario the pistons may hit the valves.
