Jock itch (tinea cruris) is a fungus, the same one that causes athlete's foot and scalp ringworm. The groin area is the perfect place for the fungi to grow and cause a fungal infection because it is moist, warm and dark.
The camshaft lift is the resultant net rise of the valve from its seat. The farther the valve rises from its seat the more airflow can be provided, which is generally more beneficial. Greater lift has some limitations.
What is camshaft. A car camshaft is a rotating cylindrical shaft used to regulate the injection of vaporized fuel in an internal combustion engine. These are occasionally confused with the crankshaft of the engine, where the reciprocating motion of the pistons is converted into rotational energy. performance camshaft for a naturally aspirated engine will have a duration in the range of 270 degrees to 310 degrees or more: 1  270 degree camshaft described as a 'mild' camshaft. 2  310 or more degree camshaft being described as a 'wild' race camshaft.
