Some people- David Vizard for one- does nott like corrugated flex tubing connecting ANYTHING in an inlet tract. Reason is, airflow is extremely turbulent and is severely limited thru the corrugations. I think it was Vizard that said the effective air flow thru such connections is less than what a smooth tube that is considerably smaller than the inner diameter of the corrugations would deliver.
It may pay dividends to rejet a carb thats tightly connected by hose to any air scoop. Bonneville runners don't because according to one runner, "it messes up the jetting at high speeds and you burn valves". Factory hood scoops used porous foam to 'connect' their scoops and this may be why. An exhaust temp gauge might show this happening before you lose metal.
I might look into finding some flex tubing that is not corrugated, but that might be a little had to find. The fuel air ratio will not be a problem because the engine is fuel injected. I think pulling air into the engine from the side of the car is still going to be better than from under the car after it has passed through the radiator.
