Can the HP of the EJ22 be boosted by cam timing ?
First, advancing or retarding a camshaft is no substitute for having the correct camshaft. Advancing or retarding will only result in fine tuning. One of the things that you are changing when you move the camshaft in relation to the crankshaft is the compression of the engine. Let’s say you measured your cranking compression of a given engine and you came up with 140 lbs. When you advance 4 to 6 degrees the compression test will show and increase to 155 to 160 lbs. (approx.). This increased compression will increase your low torque. There are many excellent books on the market on this topic area. If any one is interested I could list those books on the airsoob list.
