I am playing around with different options on installing the intercooler in the trunk. let me know what you all think. Oh, by the way I fired up the new turbo install today, man does it sound sweet.

I'll be the a-hole on NACA ducts.
To quote: The purpose of a NACA duct is to increase the flowrate of air through it while not disturbing the boundary layer. When the cross-sectional flow area of the duct is increased, you decrease the static pressure and make the duct into a vacuum cleaner, but without the drag effects of a plain scoop. The reason why the duct is narrow, then suddenly widens in a graceful arc is to increase the cross-sectional area slowly so that airflow doesn't separate and cause turbulence (and drag). The NACA duct and spoiler combination seem to be a cross purposes. A spoiler creates drag, the NACA duct is to eliminate drag. The NACA duct also exists to suck air in where there isn't enough pressure to push it in. Yet, the purpose of a spoiler is to hold a pile of air on the rear of the car, which equals the pressure you need to push air into the car. You either need one or the other. To have both seems functionally 'rice-like' -- such as putting a wing on the back of a FWD car. I'd go with a 930 look. Push the intake back to the base of the spoiler, and set the grill/intake so it is below the surface of the decklid, like a shallow funnel. |
