 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. ①)
which in turn generates more power. (Greater area under the ‘lift curve’ = 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 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. (see fig. ②)
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) 

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.

20161130_12Combining multiple spring rates into one valve spring dramatically increases it’s natural frequency. This improves the spring’s harmonic resistance which also helps reduce the chance of spring surge.

Standard oil tempered chrome silicon wire is widely considered to be the best material for manufacturing springs. However, these valve springs are made using an enhanced version of the material. Paired with our highly optimized valve spring design, these springs offer increased maximum rpm as well as improved resistance to fatigue and valve ‘jump’/’bounce’.

 

20161130_18
‘The ‘Shot Peening’ process involves the spring’s surface being ‘shot’ with countless steel pellets/particles. This forms a layer of residual stress on the surface which improves the spring’s resistance to fatigue.

 

20161130_20
‘Hot Setting’ is when the spring shape/form is set in high temperatures using a far greater load than intended. In doing so, the spring is able to maintain and consistantly deliver a high level of performance over a long period of time.

 

20161130_22
20161130_24Nitriding is used to further harden the surface of these valve springs. The process invloves the springs being treated with nitrogen which, once absorbed, causes the spring’s surface to compress and harden. This process was sepcifically employed to reduce spring fatigue when using high lift camshafts. The graph (left) shows the failure threshold of common valve springs compared to our own Nitiride treated version made using enhanced Oil Tempered Chrome Silicon Wire. Our test results showed a 50% increase in fatigue resistance making them compatible with high rpm applications.

20161130_31Oval wire valve springs feature greater compression than regular valve springs, allowing them to work with a wider range of ‘lift’ settings. This makes them compatible with both stock AND aftermarket high lift camshafts. (VR38/VQ35/KA24/4G63/4B11/G4KF)

Using highly durable oval wire allows the valve springs to compress even further whilst still retaining sufficient force. Compatible with many high lift camshafts, these springs provide reliable performance even under load at higher RPMs.
