Dry sump oiling systems are crucial when it comes to providing reliable lubrication in the most adverse of racing conditions, brutal launch forces, cornering Gs, and potential weightless scenarios mean the engine would otherwise be starving for oil.
We stopped by ARE Dry Sumps at PRI 2016 to see what’s new and available for oiling systems; specifically with the LS engine platform.
“Basically we make 11 different versions of dry sumps for the LS engine. On a car like this, that’s really low to the ground, we use our ultra-shallow pan which we call a Stage 3 system,” explained Gary Armstrong.
“It mounts straight to the block on the LS engine, it uses three scavenges; one is a roots, and it has adjustable oil pressure so you can feed engine oil out of the bottom of the dry sump tank consistently.”
On display in the booth was an Aerolite prototype car, powered by and LS powerplant and equipped with an ARE Dry Sump system. With it’s specialized oiling system Armstrong stated; “You can hold 3-4 lateral Gs that these cars will hold and have no starvation problems.”
With in the neighborhood of 1,000 pounds of downforce, these prototype cars must have some serious stiction when it comes to cornering and road-holding.
“It would basically drive on the ceiling if you wanted to, (but then you’d need an inverted oiling system) we’ll have to work on that,” Armstrong joked.
