WRX/STi 97-07 High Capacity Alloy Race Sump Stage 2
The Hyperflow WRX Stage 2 racing sump is a semi dry sump (6L Capacity) which provides exceptional oil surge reduction for the Subaru WRX / STi. This innovative design allows us to control oil surge within the sump and has a stonger oil pick up strainer and supply tube incorporated, as well as a gating system. This concept utilises a series of chambers which reduces the longitudinal and lateral movement of the oil, reducing oil surge under high G force operation on and off the track.
Traditionally the oil pickup has been an engine component and the sump is fitted around the strainer, this is no different on the Subaru engine. This creates complications when it comes to controlling the oil surge due to cornering, acceleration and braking force, as there has to be a large hole in the top baffle to allow the sump to fit around the pickup.
To counter act this Hyperflow MY07 WRX Race Sump have developed a novel Semi Dry sump (majority of oil is stored separate to the engine) to provide exceptional oil surge reduction for the 2.5 l Subaru WRX. The innovation allowing us to control and minimize oil surge within the sump and has been the incorporation of the oil pickup strainer and supply tube as a part of the sump, combined with a one way gating system to control lateral and longitudinal oil surge. A patent has been applied for on the HyperFlow Race Sump for the WRX.
