Description

One of the biggest weapons in oil-control technology is the trap-door baffle within an oil pan. Unlike static baffles, trap-door baffles open and close to allow almost unrestricted one-way fluid flow, while effectively limiting flow in the opposite direction. The baffle assemblies are arranged in a way that allows oil to move from non-pickup areas to the sump pickup area, through the use of baffle doors that have wire hinges that open approximately 1/3 of the way (so the door can close quickly without allowing too much oil to pass through). The simplest of all the Moroso baffle designs is the Street/Strip and Drag Racing oil pan that only needs to control oil in two directions, forward and backward (under acceleration and deceleration). All of these oil pans incorporate a horizontal baffle that allows oil to move toward the pickup while accelerating, and prevents oil from leaving the pickup area while decelerating. Road race baffling is designed in consideration of lateral forces as well (for left & right turns). The Diamond baffle is a trap-door system that has a square arrangment of trap door baffles, rotated 45-degrees. Each side has its own door that opens inward (towards the pickup) so the pickup is always fed.
