NACA style ducts ??

[Sandeep]

Hi all,

I'm starting to plan on where I'm going to put my oil cooler(s) for my bug. Remember, I'm going to be circuit track racing it on every second weekend, as well as driving it to and from work, but I store it during the winters....

Its a 914 2.0 into a beetle conversion, and I'm going to be using some type of Porsche shroud system to cool... which means no stock oil cooler...

I'm looking at some type of front spoiler (Kamei) or something from Carbon Joe and I understand that with a front spoiler, there will not be alot of airflow under the car.

So my question is this... I want to mount the oil cooler(s) under the rear parcel tray, over the tranny, with some fans and a thermostat. Do you think I should use NACA style ducts in the rear quarter windows (I can get the quarters made out of Lexan) to aid the cooling or not ? The ducts would have pipe extending to the coolers. Should I use one duct per cooler or is that too much ? I haven't decided on the capacity of the cooler yet...more research to do...

The ducts would add to the overall 'look' and be functional as well...or do you think the fans will be enough ?

What do you think ?
