I'm usually a pretty cluey bloke when it comes to cars but I can't figure out how a reverse scoop like u see on A9X toranas work. Is it the air escaping from the engine bay creating a vacuum that makes the air from the outside suck in to the scoop, or does it work the other way round where the scoop itself creates the vacuum, making the air from the engine bay escape through it?
Am I making sense? Although it would look stupid, wouldnt it work better if the scoop was around the 'right' way? Tags: None. Some of the reverse scoops you mention are just to allow the engine etc to still be covered by the bonnet, eg BA Boss falcons, and for others i know in some states that rules, etc dictate that you can't have forward facing scoops, i know i've seen it but i can't quote where sorry.
How does the coevette power bulge function? Does it actually get cool air to the engine or just vent the engine compartment? Many thanks in advance Phil. Your email address will not be published.

The intercooler scoop picture of the Mitsubishi Lancer Evolution is misleading. June 5, at am. July 21, at am. I love the bump just wished it had a true function instead of just a rising moon them. Please search the web for pics and let me know if it can be done.

This allows the scoop to not only funnel cooler air down into the engine but enjoy a ram-effect where air is actually pushed into the engine. They are roughly delta-shaped with gently sloped ramps and curved walls.
This is because the NACA was a federal agency developed them in s for the aviation industry. NACA ducts are common on road race cars. These are called reversed scoops or cowl-induction scoops. If a reversed scoop is mounted close enough to the windshield, that high pressure will force cool air into the scoop.
