But you already have a scoop... The front air dam

 

unfortunately it will not work that way...the internal air flow was designed to flow straight in and out the bottom...you can watch this with a fogger system and a high powered fan...i have these since I used to be in many bands and have done some testing...and the air that enters the front air dam is not really routed to flow out the side vents...of course I can't accurately simulate winds over 60mph or even close but still...when watching the fog enter the front..it is dispersed through the bottom of the car...the side vents act as a means of heat escape by turbulent air created in the bay while at cruising speeds...it's not purposely routed that way from the front air dam..at least I hope not because from the little testing I have done the fog doesn't even make it to those vents when being somewhat forced through the front of the car...

also when i shut the hood...after testing ..opening it shows how much air is actually trapped in the bay...it was like a plume of smoke..so there is an actual FUNCTIONAL need for hood vents...

i'm no engineer...but i did sleep at a holiday inn express one time..

 

try opening the hood and doing your fog experiment again. You might be able to throw some beach towels across and simulate where the vents would be.

...but then I doubt your fan is strong enough to blow air past the radiator which will result in the air bouncing back and under the car

 

it made it through the radiator..and I have another means to bypass that just to simulate the air flow...

I actually tried it several different ways because i figured since it's not a windtunnel the radiator may have slowed the air flow down enough to collect in the bay..but that not the case...if I bypass the radiator, it still collects heavily in the bay...and eventually will leak out the vents but dumps alot of it out the bottom undercarriage..

you did give me an idea....i have some cardboard that i can use and cut out a hood prototype and simulate vents...that may work...

 

keep us posted :D

 

I must have been looking at AlexCiseros' ricer version for engulfing low flying birds in a way that you look at those trick posters, because for a minute there, I saw a Maranello. It then got me thinking. How does that hood work. I haven't been one of the fortunate to have seen what lies beneath the hood of such a car (in person anyway).
I would think that a small - ish scoop, or recess I suppose, in the very front of the hood, like the aforementioned, would force cooler outside air into the engine bay, mixing with the hot air, resulting in an overall cooler temp surrounding the engine. The hot air would LEAK out the side vents and under the car rather than flow in any linear fashion since there wouldn't be an actual channel for the air to flow. I wouldn't think you'd have to worry about any type of lift from air escaping from under the car because it will be moving around in such a random way that there will simply not be any directional force. Besides, the air passing under the car would be moving much faster than the air escaping and would probably "pull" that air with it.
Then again, I am actually talking out of my ****.

 

Bump for discussion

 

Leg Motorsport hood...

 

Yeah but I think that hood is designed to get air in not extract it. Looks bad *** though.

 

The hood has vents to let air escape as well. I will look for the pic that shows air flow.

 

Ah hah. I wonder what that bad boy costs.

 

Found them

 

Sweet............

 

Before shipping from japanparts.com. The Yen has gone up since the last time I price checked when the FRP was $973.

As of today:

FRP: $1107
CF: $1572

 

Damn it.

 

Unfortunately it is not cheap I want this hood but very difficult to justify the price.

 

Yeah the heat this summer is rough and I am getting some major heat soak when I drive hard.

 

I know it seems kind of ghetto but you could put spacers in to raise the rear of the hood to let air escape until you come up with a solution.

 

nice hood. nasty price.
