Description
Tomei Camshaft Procam RB26DETT Set [Intake & Exhaust Cams]
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 equates to greater air intake)
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 traveling 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 maximized lobe travel on the lifter without exceeding the outer edge.
VALC profile camshaft have achieved this ideal by deliberately reducing the maximum cam velocity to limit lobe travel on the lifter service. (Maximum cam velocity = lobe travel distance on lifter)
