This product is intended for turbocharged engines.
When installing on a naturally aspirated engine, the optimal valve timing will need to be set using adjustable cam gears.

For further guidance on valve timing optimization, please refer to the installation manual and/or the 'Valve Timing Calculator' available on the TOMEI USA homepage.

Please note that all adjustments and/or tuning should be conducted based on the specifications of your particular vehicle/engine setup.

''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' (see fig. @) which in turn generates more power. (Greater area under the 'lift curve' = greater air intake)

Conventional profile
High lift profile without taking lifter size/radius into account.
 
Unlike the valve opening, the VALC profile ensures that the valves close at a slower rate, helping to prevent common valve train related issues.
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. isee fig. Aj
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.
A
High lift profile without taking lifter size/radius into account.
VALC profile camshafts have achieved this ideal by deliberately reducing the maximum cam velocity to limit lobe travel on the lifter surface.@iMaximum cam velocity = lobe travel distance on lifter)@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.
