Spoiler aerodymics rear spoiler design and construction
We look at how spoilers work? We also explain the difference between a spoiler and a wing. Spoilers are generally closer to the body of the car and help diffuse the air.
Wings are mounted much higher up and have an aerodynamic effect of creating downforce
Principles of porting an engine and big valve conversions
The inlet and outlet ports on the engine block are usually larger than those of the manifolds that connect to them.
This allows for scope in the manufacturing process to allow for mismatched alignment.
Generally the engine ports are larger in the upstream flow direction avoiding turbulance but power gains can be made by matching these up.
