I have what i thought was a well sorted out air intake system. A a dominater aircleaner base and stacked nascar 14x3 filters. A large hood scoop and good seal . i felt my car was 2 to 3 mph slow for the dyno numbers, at 151.5. I had some problems and opted to run without the hood or aircleaner, just the scoop. The aircleaner showed a 1 hp los on the dyno, so i assumed it was quite efficient. But the car went 154.32, or 3.8 mph faster!
So i assume it muat be aerodynamics/airflow around the front end that made the difference.
