Air flow into the rear side scoops?

[beeman]

I am planning on installing my air conditioning condenser in the passenger rear side scoop. I believe somewhere I read that there is very little air flow into the side scoops. Can anyone confirm this?

If the air flow is poor here, could I get away with a fully ducted fan to draw air over the condenser? I think I would only be in trouble if there are unusual flow patterns here such as reverse airflow.

No idea about the GTM, but I know the Aventador and Ford GT use a fan to move air on the side scoop. Not exactly sure if it's an AC condenser, but there seems to be a benefit/insurance of having a fan.

This could be for low speed cruise, or idling in any case.

If you don't use the FFR perforated aluminum mesh in the side scoop openings, you should have good airflow there. With an AC condenser, you're going to have to have a fan on the condenser no matter what so that it always has air moving thru it when the AC is on or the system will over-pressure and blow the pop-off valve and blow all of your refrigerant out.

Yeah the fan is a given.
I really think I remember hearing that air doesn’t enter those side vents, maybe they saw that in the wind tunnel?
Do you think I can get away with a Honda condenser (12"x14") and evaporator with the C5 compressor?

It is true that the GTM does not build positive air pressure inside the side scoops. This was seen in the wind tunnel early days of GTM development and I have seen this on the track.

You can grab fresh air in the area of the rear qtr windows as many builders have.

Airflow in the engine compartment and around the rear wheels is actually pretty turbulent but isn’t especially cool.

When planning i would take into account that all the air that hits your condenser needs to be moved by a fan from the side inlet. It’s not going to be free airflow like you get with the front mounted condenser but it’s similar to running your AC in a stationary car.
