A stage 2 camshaft improve modifies valve timing and carry, growing an engine’s horsepower and torque output, significantly at increased RPMs. This usually includes extra aggressive lobe profiles in comparison with a inventory or stage 1 camshaft. The facility enhance varies relying on the precise camshaft profile, engine displacement, and different modifications. As an illustration, a V8 engine may achieve 50-75 horsepower, whereas a smaller four-cylinder engine may see a 20-40 horsepower enhance. It is essential to recollect these are estimates, and precise outcomes can differ considerably.
Enhanced engine efficiency is the first advantage of this modification. By optimizing valve timing, a stage 2 camshaft improves airflow into and out of the combustion chamber, leading to extra energy. This may result in quicker acceleration and elevated high velocity. Traditionally, camshaft upgrades have been a cornerstone of engine tuning, permitting fans and racers to extract extra energy from their engines. Selecting the best camshaft is essential, as improper choice can negatively influence driveability and reliability.
