What Is a Dry Sump Oil System?

Traditional wet sump oil systems utilize an oil pan that stores the engine’s oil directly within the engine’s crankcase area. The wet sump oil system uses an engine driven oil pump with a submerged oil pump pickup within the oil pan itself. From a packaging standpoint and cost it checks all the boxes for not only OEMs but for traditional enthusiasts for street and mild performance use. However, wet sump oil systems are far from perfect. Since your five to seven quarts of engine oil is directly beneath the reciprocating assembly, the spinning crankshaft and connecting rods can aerate the oil, and having air in your pressurized oiling system is not a good thing! Additionally, under high G-loads such as accelerating, braking, and cornering, the oil pump pickup can become uncovered in a wet sump oil system, starving the engine of oil, often during high rpm use. Also, not a good thing! The answer is to convert to a dry sump oil system where most of the engine’s oil is stored in a remote oil tank and the oil pump is external to the engine and scavenges the engine’s oil from the oil pan, reducing aeration and windage losses.

Convert Your LS Engine to Dry Sump Oiling with a True Bolt-On Conversion Kit

Piecing together a dry sump oil system for the LS V8 has been frustrating for most racers. Picking up a dry sump pump from one source, brackets from another source, and then finding a suitable oil pan that’ll work and figuring out all the plumbing needs. It’s a hassle, we get it. We’ve been there too. That is why Speedway Motors’ engineers put together this complete LS engine dry sump kit that includes LS specific pump mounting brackets with a quality 4-stage dry sump pump (three scavenge stages and one pressure stage) that features an adjustable pressure relief valve to control oil pressure needs. The pump features three AN12 scavenge inlets, one AN16 scavenge outlet, one AN10 pressure feed, and one AN12 reservoir inlet. The billet pump comes with an anodized finish, a 49-tooth HTD belt pulley, and is compatible with optional fuel pump drive kits from Hilborn, Waterman, and others. The included ATI balancer that drives the pump is SFI 18.1 rated and 10 percent underdriven for high rpm use. It uses GM's mid-mount accessory drive spacing (98-02 F-Body and GTO) and is compatible with mid-mount accessory drive systems, including those with an AC compressor, allowing an LS dry sump with AC setup for those wishing to retain their AC system for drag and drive events or other street use.

A Dedicated Dry Sump LS Oil Pan Allows Lower Engine Placement

Of course, the pump is just the beginning of what we used to create our LS dry sump kits. A dedicated dry sump LS oil pan was designed in-house here at Speedway Motors. This aluminum dry sump pan provides additional clearance to drop the engine’s weight down for better center of gravity, while the pan features three AN12 scavenge outlets for quick and efficient oil removal from the engine. Additionally, we provide an AN10 pressure inlet to connect to the pressure stage of the kit’s oil pump. The natural finish oil pan includes mounting hardware, and our one-piece neoprene pan gasket for quick and easy installation on your LS engine. Compatible with popular LS applications including LS1, LS2, LS3, LQ4 and 5.3 engines, this dry sump kit will not work with LS4, LS7, LS9, and LSA applications.

AN Hose and Fittings Included for Oil Pan to Oil Pump Connections

There’s no need to sweat sourcing the proper AN fittings or hose or even trying to figure out how to route the hoses from the pump to the pan. We have that all figured out for you already with a custom hose support bracket, AN fittings, hose, and even internal hose support coil to ensure maximum oil flow without hose collapse. Simply add your choice of remote oil filter mount and optional scavenge filters to complete your oil pump plumbing. Additional AN fittings and hose for your oil tank and filter inlet/outlet will be required and is solely dependent upon mounting locations for each individual application.
