Guzimke, If You Put Them Under The Bumper You Will Feel A Lot More Power.
I thought about running the system that way originally, but then again, I had a "space" problem running the Ducts down under the bumper...I don't have a lot of room in the engine compartment with a 383 in a Dart..the ducts are 3" diameter and I didn't want to flatten them..
Also, the longer length needed for the ducts, plus the extra bends needed on those same ducts would negate a lot of the gains...Supposedly you lose about 25% of any initial gain for every 90 degrees of bend...
And last,with my car being a daily driver, I was worried about feeding a lot of road debris into the carb.
For me, it just made better sense to place it where it is..
If it was a Race Only car, I'd pull the headlights and run the ducts there.
