Vauxhall/Opel X20XE/C20XE Belt Driven Dry Sump System


AT Power's unique Vauxhall/Opel Belt Driven lightweight precision machined billet aluminium Dry Sump System is designed to prevent engine oil starvation (surge) due to G-force levels experienced during race conditions, lowering engine oil temperatures, and freeing up more of a race engines potential horsepower.

The 3-Stage high efficiency dual ported Oil Pump with positive displacement G-rotors, supplies pressurised oil directly into the engines oil system whilst simultaneously removing the aeriated oil from the Sump Pan returning it back to a remote oil tank, increasing the engines oil supply capacity.

With the oil being drawn (scavenged) directly from the low-profile Oil Pan, engine crankcase pressures are reduced minimising the oil drag on the crankshaft and lowering Piston resistance which in turn improves the engines horsepower.

AT Power's Vauxhall/Opel belt driven Dry Sump systems are supplied with a CNC machined billet aluminium high efficiency 3 Stage Oil Pump, offering outstanding oil displacements of 14.3 L/Min @ 1000 RPM from the Pressure Stage & two x 14.3 L/Min @ 1000 RPM from the Scavenge Stages, being suitable for engine speeds up to 9500 RPM & featuring an externally accessed pressure relief valve (PRV) for ease of tuning and adjustment.



Pump displacements stated are for guidance only as pump efficiencies can be affected by multiple external factors.

These Vauxhall Dry Sump Kits are designed for use with "Race Conrods Only" and are NOT suitable for use on Engines fitted with the standard OEM Conrods.

These Kits are available with a choice of Intake or Exhaust engine mounted oil pump and supplied with engine oil feed (Oil-In Assembly) adaptor kits, Oil Pump Pulley, pre-machined Crank Shaft Pulley, either 3/4" or 1-0" wide 'L'-Section drive belts & a low-profile CNC machined billet aluminium Oil Pan with multi directional scavenge turrets for the easiest routing of oil lines.

Available in a choice of 18 different anodising colours. Anodising-Colour-Swatch
