Radiator wind deflector ..wing...thingy ?
Hi All,
Sorry couldnt post a pic, but if you have a look at some web pics of original 427 street cars, like Bruce Camberns CSX3170 as an example, there is a horizontal panel in the center of the radiator opening. Looking at other originals, some times this panel is angled up suggesting that it is a deflector. Does any body know more info about these ? was it to reduce flow to the radiator for cooler climates or direct air to some other vent purpose ? How was it adjusted ? cheers to all Dave |
I've always liked the look of the splitter in the nose Dave.
Don't know the purpose of it but looks good anyway! http://www.clubcobra.com/photopost/d...edium/0513.JPG http://www.clubcobra.com/photopost/d..._Fords_008.jpg Cheers |
That's awesome BJ, is yours a panel, or a tube, hard to tell from the pics but yes, like the look as well.

Panel in the shape of a wing,radius at the front to a point at the rear, about 100mm wide.
Cheers |
My ERA's re-creation is also wing shaped and it's fixed in position. Seems the exact purpose and effectiveness of the originals has been debated forever. They don't seem to have any effect on engine cooling I'm told. Having an airplane wing in the nose would not seem to be the thing for ground hugging aerodynamics. Since the Street Roadsters were not intended to have an oil cooler maybe it was thought to help direct the air from that lower opening back towards the radiator instead of it moving up along the line of the radiator slope or something. However the area of the oil cooler is blocked off by a panel on my car - not sure about the originals.

My guess has always been that the originals' radiators slope backwards at a fairly significant angle and the splitter was intended to deflect the flow of incoming air so it entered the radiator perpendicular to its surface for less turbulence and better flow through the fins.

Hi guys. if you have a radiator that stands straight up. With the grill opening lower compared to the total heigh of the radiator. The air is mainly directed to the lower portion of the radiator. If you have a plate that splits the grille opening and is mounted on the inner end in the middle of the radiator. It will split the air evenly over the radiator surface. As you know the hot water enters the radiator at the top. With more air directed to the top of the radiator. This can help cooling. This also helps when you have a doubble pass radiator.
If the splitter plate angles upwards at the radiator and the air flows well through the core. The flow over the splitter can increase downforce very slightly. Competition radiators made by PWR can be made with the fins in the radiator on an angle. That way if the radiator is tilted back on the same angle, the air will flow straight through the fins without causing uplift. Bender |
Front down force, I have tried it with and without and the nose stays down with the panel installed. Very noticeable above 150.

oooh, Bruce, i'm a big fan of you and your car, its my screen saver actually :), yes even from downunder in Oz !
Would you have any pics of the splitter and how it adjusts? cheers Dave |

My radiator leans forward at a good angle so I made the number plate to lay down at speed (60 k ) and stand up when stopped. Damn plate reader cameras have stymied this for me.

Where can I get radiator wind deflector?

I formed the shape out of hard foam material and then fibreglassed, came up a treat!

I suspect an aluminium louver will disappear from the back veranda :)
