Selecting a camshaft for a given engine’s purpose usually involves a compromise between low- or high-end power options. This is true for normal aspiration as well as boosted applications. The lobe separation angle (LSA) is one of those factors where engine builders have to make a choice between those priorities. LSA measures the angle (in degrees) between the maximum lift points, or centerlines, of the intake and exhaust lobes. Thus, it directly affects the amount of valve overlap; that is the brief period of time when both the intake and exhaust valves are open. If they're not open for sufficient time, air flow suffers at mid to high rpms. Keep both open for too long and boost escapes out the exhaust.
Our 276° Widelobe Cam is a must for making high-rpm power in turbocharged (or centrifugal supercharged) street and race engines. Powerband comes on smoothly and seems endless. Idle quality is lumpy idle but still delivers excellent street manners. Low-end torque is diminished slightly but low midrange is left intact. "Rip" from 3500 to redline is VR6-annhilating amazing. Head flow work is hugely beneficial for maximizing peak gains. Specs. 236° @ .050", .444" lift, 114° lobe centers.
Note: Heavy-duty valves spring required for OBDII 2.0l 8v ('95+) engines
