: : The countoured plastic piece behind the front bumper(venturi panel)pushes the air up towards the intake. : the only panel is the splash gaurd. it is either horizontal (stock), or pointing down and back (JWT). This creates a vaccum which causes stalling while decelerating with the clutch pedal in. True, the only panel is the splash guard. With the stock airbox in place, the guard is in fact vertical, not horizontal. Thus makes no difference. Stalling occurs when too much air is ingested with the clutch in (that's why NA Z-ers place duct tape over certain areas of their intake to prevent this), not because of the splash guard blocking the intake. : A ducted louvered panel does nothing more then add a slight pressure increase on the top of the JWT airt filter. The panel you are talking about the is Stillen ducted panel which is not the topic of this discussion. The Stillen louvered panel is a different panel and should not be confused with the ducted. Your argument is true for the ducted panel as air is forced into the ducted openings by air flow going over the car which in turns create a slightly higher pressure in the intake area. However, the argument doesn't not hold true with the louvered panel which has an opposite effect when cut open. The placement of the louvers on the panel creates a vacuum. And a side effect to cutting open the louvers is reduced airflow through the radiator resulting in a slightly higher coolant temperature (of which I have tested with a consult). : If you open the slits on the louvered panel, the air being forced up towards the intake becomes turbulent and can actually escape out the panel. : all the air in the front end is turbulant. ALL of it. The only way to cure air turbulance is to build a cold air intake plenum : Paul at Avalon did testing with this on his old TTZ race car and noticed HP drop. : Where are the DYNO's proving this?
: It just doesnt make sense is all. Dyno's may or may not show a difference but one thing about dynos that doesn't help this debate is that dynos do not simulate ACTUAL forced air flow and pressures under normal driving conditions. Sure we have fans that blow onto the car but it's not enough to remotely recreate those kind of conditions plus they're generally there to help cool the car. Hopefully this will help clear up some air and made some sense.
