Roof Scoops Purpose

However in an effort to shave every spare pound off my 93 hardtop i have decided to remove the whole ac system.

Roof scoops purpose.

Deep 6 rally team merch and also random car sticker. Hood scoops are for cooling the engine or engine components. I have read the answers below and they only tell half the story. Hood scoop functions cool air.

For rallying like cid498 said. After all most race cars use plastic windows sealed against the doors and air conditioning isn t an option. In most modern vehicles internal combustion engines breathe under hood air or air ducted from under the front bumper through plastic and rubber tubing. Anyone has idea.

The large roof scoops used on world rally cars and race cars are usually there to provide fresh air for the driver. For rally cars a hood scoop is used to create high air pressure in the cab of the vehicle to help reduce dust from entering and improve visibility. I do like the draining mechanism though. Ok its for looks and for some of the cars its got their functions midengine uses it for air intake since their engine does not get enough air from the back not like front engines do they put theirs on the roof or sometimes you see them on the sides nsx and mr2 got them customized.

If this was the real reason then every track race car. All they are is a fresh air inlet for the cabin if you ve ever watched any. I might be wrong then but another thing is it creates downforce. The roof scoop is unlike any other roofing ventilation.

Just a quick video on how i installed my roof scoop and vent on my 2004 subaru sti thanks for watching. The proven effectiveness of cross ventilation has been well documented but often neglected. Roof scoops for some rear or mid engine cars are used for the same reasons a hood scoop to flow air to the intake for the motor or an inner cooler. The tailored ventilation system purpose built for the harsh australian climate.

Not sure if it would work on my application since the scoop seems to be purpose built to only work in light rain at most at drift events. Roof scoops on street cars are lame. The high operating temperatures in the engine compartment result in intake air that is 28 c 82 f or warmer than the ambient temperature and consequently less dense. It is a complete system which creates cross ventilation within the roof space.
