Valve Spring Spring Rate at David Mcgraw blog

Valve Spring Spring Rate. When the valves have fully closed, the pressure against the valve in many stock engines is usually between 70 to 90 psi. the valve springs must apply a certain amount of spring pressure to maintain correct valve operation at normal engine speeds. Of pressure at 1.750 installed height. Of pressure to compress the spring a full inch. simply said, valve springs control an engine's mechanical rpm capability and must be properly matched to the camshaft. an important factor when selecting valve springs, is choosing the correct seat pressure, open pressure, and spring rate for the camshaft being used. We’ll say that it has a spring rate of 300, which would tell us that it takes 300 lbs. the valve spring rate is vital for designing engines that perform efficiently across a broad range of operating. If you purchase a camshaft that raises your engine's powerband from a maximum rpm of 5800 to 6500 and don’t change the valve springs, your engine's maximum powerband rpm is still 5800. as an example let’s look at a valve spring that has 100 lbs. changing the rate of your valve springs can be used to fine tune performance based on your expected rpm range. performance cam grinds require higher spring rates, which is the amount of weight required to compress the spring at a given distance.
