Comparative CFD Analysis: Original WL250 vs. New WL250MSHD
This analysis compares the aerodynamic performance of a baseline 70″ Original WL250 and the new and improved 70″ WL250MSHD wing across various angles of attack (0°, 5°, 10°) and speeds (60, 100, 140 MPH).
The comparison focuses on the fundamental forces of Lift (downforce) and Drag, and the resulting power required in Horsepower.
Downforce (Lift) Comparison in Pounds (lbs)
This comparison shows the downforce generated by each airfoil, which is the critical force for cornering traction.

Detailed Comparison of Forces and Power
Aerodynamic Performance Comparison: MSHD vs. Original Airfoil
Drag Force (D) is the resistance opposing the car’s motion, and the Power Required to overcome it is a direct function of drag and speed.
Lift Force (L) acts as downforce in racing, pressing the car onto the track for improved traction and cornering grip.
