The cause of engine failure
With the past few years spent on developing go fast parts for the 4B11 a dry sump system was once again a necessity. The motor may be new but the nature of an engine has not been changed. High RPM launch control, Cornering, Launching, Braking, any one of these will upset the oil level in your car. In drag racing what we experience is 2 step launch control for 2 – 4 seconds (depleting the pan of oil) a multiple G-force launch, moving the oil to the back of the pan. Now, let’s pull the parachute! What little oil is left is pushed to the front of the motor. You can see why we resorted to overfilling our engines and immediately shutting them down after crossing the line. Overfilling the engines just would end up filling our breather tanks, causing other problems. All of these problems together can cause the oil level in the pan to run below the oil pickup, causing the pump to run dry and destroy your engine, oil pump, or turbo.
