Valve Springs Pressure at Shannon Marx blog

Valve Springs Pressure. Simply put, valve spring pressure is how much pressure is on the valve at a specific measurement. In theory, you can gain free horsepower just. When valve bounce occurs, dynamic compression is lowered resulting in a loss of power. The valve springs must apply a certain amount of spring pressure to maintain correct valve operation at normal engine speeds. Part of what goes into this is what the spring’s rate is per inch and the installed height. Open pressure is the force the spring applies against the rocker arm when the valve is open, while closed pressure is the measurement. An important factor when selecting valve springs, is choosing the correct seat pressure, open pressure, and spring rate for the camshaft being used. Of pressure at 1.750 installed height. As an example let’s look at a valve spring that has 100 lbs. Valve spring pressure must be enough to shut the valve and keep it from bouncing off of the valve seat. When the valves have fully closed, the pressure against the valve in many stock engines is usually between 70 to 90 psi. The valve spring pressure measurements you will see are what it has for seat pressure and open pressure. The open pressure is the pressure at the spring's specified compressed length, which may or may not equal the actual valve lift on your engine: Bouncing the valve off the seat also can cause valve breakage or piston to valve contact. We’ll say that it has a spring rate of 300, which would tell us that it takes 300 lbs.

The open pressure is the pressure at the spring's specified compressed length, which may or may not equal the actual valve lift on your engine: As an example let’s look at a valve spring that has 100 lbs.

Open pressure is the force the spring applies against the rocker arm when the valve is open, while closed pressure is the measurement. Simply put, valve spring pressure is how much pressure is on the valve at a specific measurement. Of pressure to compress the spring a full inch. An important factor when selecting valve springs, is choosing the correct seat pressure, open pressure, and spring rate for the camshaft being used. In theory, you can gain free horsepower just.
