Dry Sump System Installation Schematic

The AT Power's Mitsubishi Semi-Integrated 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 existing 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.

This compact design utilises the existing (OEM) Oil Pump belt drive system, eliminating the need for any external drive belts as seen on the traditional belt driven Dry Sump Systems.

The Integrated Scavenge Pumps simultaneously draws (Scavenges) the aeriated oil directly from the Sump Pan into a remote oil tank increasing the engines overall oil 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.

The fully Integrated Scavenge Galleries between the Dry Sump Pan and Oil Pump reduces the quantity of vulnerable external oil pipes and potential oil leak paths along with the additional installation costs of external oil pipes and hose fittings

This product features our high-quality Billet machined low-profile Oil Pan with Turbo drain features, Front Cover and integrated 3-Stage high efficiency dual ported billet machined oil pump, featuring an externally accessed pressure relief valve (PRV) for ease of tuning and adjustment.

This compact design also eliminates any front-end packaging issues in the engine bay and eliminates any risk of an auxillary drive belt failure.

With the addition of an Oil Cooler, the system will reduce Oil temperatures and improve the durability of a race engines life, providing the optimal installation for the serious Mitsubishi racers.

The standard Exhaust system will require modification to prodide clearance around the Oil Pump.
