Honda K20/K24 Belt Driven Dry Sump Systems


AT Power's unique Honda K20/K24 Belt Driven lightweight precision machined billet aluminium Dry Sump Systems are 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 Honda K20/K24 belt driven Dry Sump systems are supplied with a CNC machined billet aluminium high efficiency 3 Stage Oil Pump, offering outstanding oil displacements of 20.1 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.



These Dry Sump Kits are suitable for use with K20/K24 engines.

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

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, 3/4" wide 'L'-Section drive belt & a low-profile CNC machined billet aluminium Oil Pan with Turbo drain feature and multi directional scavenge turrets for the easiest routing of oil lines.

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