WebJul 6, 2006 · ANSWER Lobe separation affects valve overlap, which affects the nature of the power curve, idle quality, idle vacuum and the range of the power curve. Duration, lobe separation and valve overlap all affect each other. For example, if you want to increase the valve overlap without changing duration, you can decrease the lobe separation angle. WebMar 16, 2010 · Lobe separation angle (LSA) directly affects valve overlap. As the LSA is decreased (called a “tighter” LSA), the overlap increases. An LSA of 108° is considered tight; 115.5° is considered wide. Tighter LSAs may produce more peak torque, but will yield poorer idle characteristics. A tighter LSA will also move the power range down in rpm ... coronary philips
