The Hyperflow WRX "Semi Dry" race sumps come in stages 1 and 2.

Both models of sump have larger capacity, a standard Subaru sump holds 4.8 litres of oil, the Hyperflow models hold 6 litres.

The stage 1 sump has a gating system incorparated to stop longitudinal and lateral movement of the oil under high G force cornering.
The stage 2 sump has further improvements in that the oil pick is part of the sump itself allowing even more baffling to be installed to stop oil surge. The oil pick up is installed from the under side of the sump.

On both model sumps top and bottom plates are CNC machined from solid alloy plate, the top plate seals to the engine block with continuous section O ring, all side plates are from laser cut thick alloy plate and all components are machine welded together to give a professional finish.

The bottom plates has cooling fins machined in to it to give extra oil cooling benefits.

We recommend the stage 1 sump for street applications and the stage 2 sump for motorsport applications.

You can choose between a polished alloy finish or covert black.

Drifting, Competition, Street and Circuit
