Purpose Of A Roof Scoop

Just a quick video on how i installed my roof scoop and vent on my 2004 subaru sti thanks for watching.

Purpose of a roof scoop.

This small increase in pressure works wonders to keep out dust and sand from the rally stage. Getting back to aerodynamics today i explain how hood scoops and bonnet vents work for road and track. You ve probably noticed that if your car windows are open fresh air gets sucked in. Anyone has idea.

Any dust floating around the cabin will seriously inpeed the driver s vision and make it much harder for the co d. This is because there s a negative pressure created by the vacuum bubble behind the trunk. On a rally race car a small roof scoop creates positive pressure in the cabin pushing dust out of window. I have no idea what good a roof scoop could do.

The main reason for having a roof scoop on a rally car is to actually pressurise the interior of the car slightly. For a normal street car it s just gives it look to make it look more aggressive. So a car that has the engine in the front the purpose of the roof scoop is merely for looks. For rallying in those cars such as the wrc cars they perform a function but i don t know what.

It cools off an appropriate spot when you start to get hot headed. If the car was a rear engined air cooled engine car like an old vw bug it could be used to force cooling air over the motor. The only other reasons for a roof scoop are to cool rear mounted heat exchangers radiators or to provide intake air for a rear or mid mounted engine. To flush out the.

Re read what i said its for the passenger area of the car. Also on mid engined cars the roof scoop is the air intake. I explain the basics of how the airflow works around. In almost every case a large naca duct will provide more than sufficient airflow without increasing drag raising the boundary air thickness or causing turbulent airflow.
