Gnarley is right they do help in the Hp deparment.The only thing to watch out for when running a dry sump oil system is cold oil. The high flow rates of the oil can posibly break the pump or cause internal damage. make sure the oil is good and warm before you really nail it. But they are the best way to oil a engine if you are going to turn lots of Hp and Rpm.
