AT Power’s Peugeot/Citroen EW10 EW12 Belt Driven Dry Sump System
AT Power’s precision-engineered Peugeot/Citroën EW10/EW12 Belt-Driven Dry Sump System is a lightweight, billet-aluminium solution designed to prevent engine oil starvation during high-G racing conditions. This advanced system helps lower engine oil temperatures while unlocking more horsepower potential.
Key Features:
- High-Efficiency 3-Stage Oil Pump
- Dual-ported design with positive displacement G-rotors.
- Delivers pressurised oil directly into the engine while simultaneously scavenging aerated oil from the sump.
- Returns oil to a remote tank, increasing the engine’s total oil capacity.
- Reduces crankcase pressure by scavenging oil directly from the low-profile sump pan.
- Minimises oil drag on the crankshaft and lowers piston resistance, improving overall horsepower output.
Precision Machined for Maximum Performance:
AT Power’s CNC-machined billet aluminium oil pump delivers outstanding oil displacement:
- 14.3 L/min or 20.1 L/min @ 1000 RPM (Pressure Stage)
(20.1L/min required if piston cooling jets are still being used)
- 2 x 14.3 L/min @ 1000 RPM (Scavenge Stages)
Suitable for engine speeds up to 8500 RPM
Externally adjustable pressure relief valve (PRV) for easy tuning
