In a thrilling episode of Engine Masters by MotorTrend Channel, the team delves deep into the heart of engine performance by testing various camshafts with different exhaust durations. They focus on split pattern cams, where the exhaust duration exceeds the intake duration, to uncover the impact on power delivery. With custom camshafts featuring a 268° intake lobe and varying exhaust durations, the team sets out to push the boundaries of performance limits. By exploring the effects of extreme exhaust duration splits on a small cubic inch big block Chevy engine with high compression and top-notch cylinder heads, they aim to unlock the secrets of optimal camshaft configurations.
As the team tests camshafts with 272°, 278°, and 284° exhaust durations, they meticulously analyze power numbers and torque curves to decipher the subtle yet crucial differences in engine performance. Through intense scrutiny, they uncover how changes in exhaust duration can influence torque delivery and power output across different RPM ranges. Delving into the intricate trade-offs involved in altering exhaust duration, the team navigates the delicate balance between sacrificing bottom-end torque for heightened top-end power. They ponder the repercussions of early exhaust valve opening on cylinder pressure dynamics during the power stroke and speculate on the potential outcomes of further increasing exhaust duration on overall engine performance.
With a keen eye for detail and a thirst for uncovering the nuances of engine behavior, the team embarks on a quest to determine whether there is such a thing as having too much exhaust duration on a camshaft. By pushing the limits with a cam featuring a whopping 284° exhaust duration, they compare power numbers and torque curves to previous tests to gauge the impact of extreme exhaust duration splits on engine dynamics. As they scrutinize the results and delve into the realm of resonant wave phenomena, the team grapples with the complexities of optimizing camshaft configurations for peak performance. Amidst the roar of engines and the thrill of experimentation, Engine Masters delivers yet another exhilarating exploration into the realm of automotive engineering.
