I'm just curious to know, do those deflector plates really do anything? I was looking on Colletti Motorsports, they make one for the Integra. Just wanted to see if ya guys thought it was practical or not. I've seen a lot of cars, especially the old RTR cars running them.

 

Anybody!

 

I don't know you be the judge. What they effectively do is entrap the outside air to the radiator and isolate that air to the radiator. The deflector plate just keeps the cool air from escaping into the engine bay. I believe duct has the exact same effect.

 

from my research a deflector plate is a part of a bigger aero system which includes escape ducts in the engine bay, an air dam, a splitter underbody tray and a rear diffuser, all direct air to a specific area, some to increase the effectiveness of the specific system (brakes, cooling, etc.) and some to create downforce.

it makes sense

however I would stay away from the vented versions since I think they do that just to make them look more ricerfantabulous I'm kinda partial to this one myself

 

I was looking at this same thing just the other day. It sounds like it would keep some air from going under the car and send it through the radiator instead. That's the theory anyway... The real question is: exactly how much air comes in through the bumper and then changes direction to go down under the radiator? It seems like there's not really anything to cause it to flow downward.

Maybe it's time to construct a wind tunnel...

 

Yeah, I'm not talking about the Upper deflector plate, I'm talking about the lower-bumper plate. I've seen the RTR's run them, and also CollettiMotorsports use them.

 

one of my competitors in SM who runs a turbo DSM has fabbed up a nice plate all around his radiator, to make sure his radiator is getting as much air as possible.

it sounds like a great 'DIY' idea and <U>I'd do it if I had issues with my cooling system... </U>
but mine runs perfectly so I'm gonna spend my time making ricerfantabulous C-Pillar bars and B-Pillar Harness bars.

 

You can use the lower and top deflector but what about the sides? For the system to work optimally, you should seal the sides as well. Otherwise, air will escape out the sides (at least on my car, there is a gap between the rad support and the rad itself). Simply put, air is lazy and will take the path with the least amount of resistance.

 

Well basically, Colletti made a design for the Integra's, which has two verticle ducts that go on both sides of the radiator deflector plate, So air can't go anywhere else, either directly through the plate or through the ducts for the brakes. It's pretty cool

 

it might not have any issues but can always work better

 

I was thinking about it a lot today, and I came to realize that it wont work on my car. The A/C lines are in the way of the radiator, so 86' that option for a deflector plate!
