what is the tights center ling should a cam be ground on to us factory EFI coumputer system in a 93 lx. Also what c/l should be used with a super charger at 6/7 pounds
ide always use a cam of 112-114 LCA for fuel injected and or supercharged application to prevent loss of cylinder pressure due to ecessive valve overlap, tighter lca's are used for two reasons, desired higher operating rpms where there is less time to fill the cylinder thus making it advantageous to hold the valves open as long as posible, and lousey cylinder heads, with poor flowing ports its important to hold the valve open longer and have more overlap so that the exhaust pulse can help pull in the intake charge from the poorly flowing intake port, as the quality(port velocity/flow) improves with different head designes(stock vs afr's) the required durationcan decrease and the LCA can increase for the same operating rpm, improving torque, hp mileage and throttle responce, this is just a breif decription and there are ALWAYS exceptions and misunderstandings of the principled involved, hope this helps
