Oil to Air Sidepod

Subteam: AerodynamicsSubsystem: Side AeroAssembly: Lubrication AssemblyCars: CR25, CR26I

Purpose

The sidepod serving the oil-to-air heat exchanger on CR25 and CR26I.

Function

Captures and diverges air into the oil duct and oil cooler core. Separate from the water sidepod because CR25 split oil cooling off the water circuit.

Design Process

No part-specific design process is documented. The Side Aero subsystem design process applies: 1. 2D sweeps to find airfoil placement within a stack. 2. 3D placement of the stack itself, judged on whole-car downforce, drag, efficiency and center of pressure. 3. Compare against the current combined-run baseline rather than against an isolated case. 4. Accept only where the gain is outside the CFD margin of error.
