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.
CNC BILLET COMPRESSOR WHEEL
Significant improvement over traditional cast compressor wheels. Machined from aerospace grade materials, these highly durable lightweight compressor wheels feature thinner blades with a larger surface area for significantly improved airflow and turbo spool.
Our friends at Seoufulracing, Mr. JAY KIM, was kind enough to make detailed installation guide video of our TOMEI TECHNICAL TRAX ADVANCE LSD for the Hyundai Genesis Coupes.
With TECHNICAL TRAX ADVANCE, he said
“LESS UNDER STEER”
“MUCH FASTER EXITING THE CORNER”
“VERY STABLE AND PREDICTABLE THROTTLE CONTROL”
“OVERALL MUCH EASIER AND PREDICTABLE TO CONTROL”
He also said,
“SHOULD BE ONE OF THE FIRST THINGS TO
INVEST FOR ANY TYPE OF MOTORSPORTS YOU ARE INTO”
