The size of the opening has little effect on cooling ability. It is notably more important to control the speed of the air THRU the radiator. Radiator core depth should be given some serious thought.Too much speed and the air does not have enough time to absorb the heat as it passes thru. Inlet duct design is more important that opening size. Choose the opening that you want and then work on the cooling. Even the design of the leading edge of the radiator fins is a concern. Fan diameter, pitch and RPM should be carefully considered as well. A larger grill opening will reduce both mileage and speed. Perhaps a concern at this point is to give some consideration to the design of the leading edge of the grill 'screen'. A 'non-aerodynamic' leading edge will create turbulence and inhibit smooth airflow thru the radiator. Don't overlook the possibility of a front spoiler that would vector air flow up and into the front of the radiator = speed, down force and cooling. Those high areas between the nose and the front fenders are going to give you quite a bit of turbulence. If you made the front spoiler go between the centers of those two 'upswings', and put a vertical edge on both sides of the spoiler you would both increase the cooing and decrease the turbulence = more speed, mileage and cooling.

Anther approach to all of this is to consider not driving over 100 MPH, LOL.

Kerry, it's nice to see back working on the car. It's looking good.

Hi Kerry
The 7th time is a charm!!
I like this design!
The proportions are much better.
With that much visibility through the mesh all the items behind it will need to be blacked out so they disappear, and the grille stands out!

Congrats on a successful venture.
So what’s next on the list?

Steve

That's looking really good Kerry. All that effort to design and build this car deserves a custom cloisonné emblem somewhere in the grill.

I agree Bob. I plan on some kind of emblem at the top junction of the middle bar and the grill top. It would also cover the center hood trim intersection with the grill.

Will, I don't think it will ever see 100 mph At least not with me driving it.

Steve, the only reason you see anything at the bottom is because its up in the air and the camera is down low. On the ground it will be dark.

I've seen examples of this in high performance applications. The best I've seen was in John Britten's V 1000 race bike. He used ducting to create high speed laminar flow into the tiny radiator which was mounted at an angle, not vertical. The mounting angle caused turbulence as the air impinged against the fins. The air pressure against the fins greatly increased their heat shedding ability. This trick allowed him several advantages. He was able to use a tiny radiator to save weight including the volume of water in the system. Also he was able to place the radiator out of the way under the seat to decrease drag. Long story short, if you mount the radiator at an angle it can be smaller. Better aero and better cooling.

The radiator is from a 65 V8 Mustang with AC. I suspect it will do fine with my 250 6 cylinder.

Finally, FINALLY got the roadster outside for some decent long range photos. I'm a bit biased but I am VERY happy with the grill, decklid, new door tops, and all the other minor and major things I've done since I last had it outside two years and two days ago.

It's good to see it outside in real light. Thanks for posting, Kerry.
