pok nik said:ok, ok...lets get back to business...wat can firmer valve spring do? can it actually increase torque, coz i ve heard sum1 said that after changing firm v.spring, the rpm goes up faster...
Oderf said:it helps to reduce the "valve float" phenomenon....at high rpm sometime the valve spring cant keep up with the fast movement of the valves...so at times the valves not even properly closed yet but they already pushed open...so, the combustion chamber weren't properly sealed during the explosion resulting in power loss....
