cold air induction L88 hood

musclcar-------, Anytime you can provide cool dense oxygen rich air to the carb you are helping to support better combustion,which affects power output.Granted the HP gains will vary with different modes of air delivery ,rammimg the air from a high pressure area will give you the best HP gains.Whichever form you use it is best to diffuse the air thru your air filter.And like camarojoe said the hood scoops, lumps and bumps did look cool.Your setup sounds like it will concentrate the cooler air around the carb a little better.A little gain here and there and it does add up and give the look you want.----JoeG

I remember reading some time ago that for every 10 degree drop in ambient temperature entering the carb there is generally a gain of approximately one percent in horsepower. I'm not sure what the baseline temperature would be and at some lower temperature it seems there would be a point diminishing return. Has anyone else heard of this?
I also remember that GM had built the first wind tunnel for aerodynamic testing among the U.S. automakers which led to the development of what I think would be the first cold air, cowl inducted, hood used on the '67 L-88 Corvette.
