The overall design and construction of the camshaft has been very heavily revised from the standard configuration. Areas of stress, rigidity and weight all gaining significant benefit. Generally camshafts are manufactured from solid blanks. TODA Racing VTEC KILLER Camshafts are produced from hollow blanks. Being hollow not only reduces weight but also improves valve timing accuracy through a reduction in flexing as the overall rigidity of the camshaft is increased.
Unlike a Vtec camshaft, the Toda Racing Vtec killer camshafts have two cam lobes, which are of the same size. The Toda Racing Vtec killer camshaft is designed to bed in quickly and have a low wear rate
Characteristics:
There is no longer a secondary (Vtec) lobe on the camshaft, the mid rocker arm is therefore redundant. It is removed and replaced with a rocker arm spacer. (PN. 14632-B16-000) The two pins in the remaining rocker arms are also removed. The oil feed rocker arm is fitted with a rocker arm plug to prevent any loss of oil. (PN 14651-B16-000) The benefits in a racing application for omitting the Vtec is the reduction of the valve train (reciprocating) mass and friction. The reduction in reciprocating mass and friction results in better engine response and increased valve train reliability. Furthermore, another benefit of disabling the VTEC system is the removal of fluctuations in the oil pressure system, securing reliable oil feed to all the main moving components. The factory “Lost motion devices” should be removed.
For best effect, Toda Racing Vtec killer camshafts should be used in conjunction with Toda Racing adjustable camshaft pulleys and Toda Racing’s 4valve throttle body Sports Injection Kit.
