http://www.amsoil.com/storefront/bf.aspx Does anyone know if this is good for racing(doesnt mess with oil pressure)? They show iit installed on daily commuter vehicles but no weekend-race cars. Also, the "original" kit(BMK-11) they have the bypass filter mounted remotely; oil is tapped from where the oil pressure sensor is with a T-valve, and oil is filtered through the Bypass filter then goes back to the oil pan. They say only 10% flows through the bypass filter. Well, on the Dual filter system(BMK-13) the Bypass filter is parallel with the regular filter, and the oil goes to the bypass filter first. wouldnt this be a bottle neck for the oil(more then 10% going through the bypass filter)? The bypass filter is suppose to filter out smaller particles so im thinking its harder for the oil to flow through there.
