if you have a stock motor forcing more air in the carburetor will only make the motor burn more gas to make up for the air to gas ratio in your brain box, you might get 1 to 2 hp but your going to pay in the gas price at the pump ,the gas is doing all the work not the air, i use a
MANUALLY OPERATED
scoop and hood louvers to get some cold air in and hot air out of the engine bay, with headers it get a little hotter then the stock manifolds, lets say a lot of work from cam to
Performance intake manifold a 4 barrel carburetor to a
supercharger. thats how it works not with a scoop only,,
