Point Of Roof Scoop

Why would someone put it on the roof instead of the hood.

Point of roof scoop.

If this was the real reason then every track race car would have a roof scoop as well. The idea of roof vents existed for hundreds of years with natural vents employed in chinese buildings during the tang dynasty natural ventilation ducts in the buddhist monks caves and wind catchers incorporated in arabian architecture. Scoop measures approx 19 x 17 and 3 5 tall. But if you re just after that snappy rally car look install the scoop by itself without cutting a hole in the roof.

Wide mouth helps to feed air to your roof vent but a small air escape in the back of the scoop reduces noise and lift when roof vent is closed. Yes the roof scoop will give some air flow in the cabin however there are far more efficient and aerodynamic ways of doing so. It doesn t even look good. Vent roofs with steeples towers or cupolas can be found in different buildings from barns to cathedrals.

I understand how hood scoops work but it kinda defeats the purpose if someone mounts it on the roof the piping is to long from the roof to the engine to make any power gains. It is attached directly to the decking along the bottom of the roof slope and above the underlay on the sides of the roof. The contractor shall verify nailing spacing of roof sheathing or strapping and shall report deficiencies to site manager. Due to its location the air enters clean with no dust and it contributes to keeping the temperature down as well as to keep positive pressure inside the cockpit preventing dust from entering by other car openings.

A roof scoop consists of a small opening at the front of the roof designed to allow some fresh air to enter inside the car. The main reason for having a roof scoop on a rally car is to actually pressurise the interior of the car slightly. The roof system as identified in the scope will carry a five year rdr labour guarantee and a manufacturers 10 year warranty 7.
