I have one bought from evasivemotorsports.com (great guys do do business with!). i am looking at the design and don't really see how air can be channeld or how it will improve any airflow. it looks like just a plate of c/f for engine appearance (which is why i bought it). i just fail to see how it can direct or cool anything...can someone explain this?

 

It helps to cover the gap in the bumper/front support by the hood latch, where air flowing in through the bumper mouth can escape and go up and over the radiator. It's not something you'll notice, unless running very high speeds, but anything you can do to prevent it can help cooling.

 

more of "the look"

 

huh?...pics?

 

uhhh.

 

Like Tony said its not really channeling air, its trapping it and not letting escape over the entire engine. Not really sure how well it works but it looks nice.

 

okay...if it's not letting cool air into the engine...then people with short rams like the k and n typhoon, popcharger, gruppe m, and afe are sucking in higher temps???...that kinda sucks....(typooon owner here...)

 

well theres no possible way it is going to trap all the air plus the air that comes in everywhere else, it wont effect it. It is just letting cool air cool the radiator it wont effect the short ram.

 

Having performed many tests (especially on the 240sx) with a proper cooling plate on the upper and lower half of the 240sx, at hwy speeds, we have seen a 25 degree temperature drop in the air temperature after it had passed through the radiator. This is extremely important on FI when considering that the air has to pass through the intercooler, a/c condenser, and finally through the radiator.

Also, on a stock PPW 350z, you can see how much air escapes the "path" through the radiator by looking underneath the hood right where the latch is mounted there is a good amount of dirt.

I attached a quick pic to give you an idea of airflow w.out the cooling plate.

 

I want at least five. One for the top and one for the bottom of the radiator. One for the bottom rear of the car...as an air diffuser. Finally one I will convert into a big wing to get some downforce.... I wonder if they have stickers?

 

its all for looks, If you look on our hood you will notice that it has rubber seals all around the hood latch area.

 

i'm just sitting here thinking about it, and it seems like natually you can only cram so much air into the bumper area before more air doesn't really want to actually go in it anymore and will just get turbulent and possibly not actually go into the bumper area.

Like if the air was water and you poored all this water into the bumper, eventually it fills up and you can't put anymore in it.

So having the gap there lets some of the air out into the engine bay. If you have a vented hood, it'll work out really great for cooling because the cold air will come in, then leak into the engine bay, warm up a little, then flow out the hood vents. Otherwise where exactly is the fresh air coming into the engine bay? Just little spots here and there?

 

a huge pocket of low pressure air gets trapped under the car at speed. thus you get a good cycle of air being pulled through the radiator and back under the car. if you look at any race car, there is a reason they create a closed box for the radiator inlet. you can get positive pressure in the tract, thus meaning more air, in turn more medium to carry off the heat. vented hoods and fenders also help create more of that low pressure behind the radiator to help draw more air through it.
