Project Air Scoop
A few days ago I fit a sheetmetal air scoop below my front license plate right under the 78 valance opening...well, I whacked it driving out of Kragens driveway...I knew that plastic would be better...the following pic's show my new scoop....
Sheetmetal scoop
New plastic scoop from dust pan....
This air scoop has reduced coolant temps approx 5 degrees...small gain,but an improvement....and the plastic version is more forgiving...

This will be the next thing in the Ecklers catalog for sale. Good job on the scoops. If it works and does a good job,

I'll let you in on something that will complement you scoop. Getting the ai out somewhere else will allow that scoop to give you waaay higher temp gain than 5 degrees. The engine bay in a Corvette is notorious for holding air, and creating a large hot pocket above the firewall, just beneath the windshield line.
At that upper edge of the hood, where is seals down in front of the windshield is a lip, or ridge, maybe an inch wide. I can post a pic if you're confused.

On that rib, ridge, lip...whatever you want to call it, make some vent holes. Nothing huge, but several inches side. Maybe two 5"x1" vents in that top lip. Cover it with wire mesh, and rivet it in place. It's on the belly of the hood so you can't see it from the outside unless you are sitting in the cabin.
Doing this will allow that scoop to bring in more air and force hot air out of those new vents. I think you could expect a 15 degree drop in temp at speed.

These pics show my 69 cowl hood...note yarn is "vacuumed" into hood opening...second pic is at 50 mph....
Understand the idea...
Thanks, Rich

I drilled one inch holes across the raised area on the bacl of the hood. The hood keeps its rigidity but allows hot air to flow out from that area where heat builds up. It does not change the running temps while the car is moving because of the high pressure at the base of the windshield, but it does allow hot air to escabe in stop and go traffic and while sitting still. Popping the hood after stopping is an easier way to accomplish this.

This is what first got me into this thinking.
On the Corvette I have I have not done this. I changed to a good stat, and a chemical coolant and I run at 180 allt he time. My first Vette though got the cowl vent treatment, and it helped a lot at speeds up to 35. Couple that with a scoop in the front under the radiator, and I'd bet it'd work to twic those speeds.
what kind of coolant do you use?

Rich,
Looks great but I do have one suggestion........I think I'd make the brackets attach from the inside. I mean have the brackets come from the inside of the scoop. That way you cannot see them on the outside of the scoop to make for a cleaner looking installation. I know the only time you would actually see it if you get drunk
and fall down in front of the car though.

and fall down in front of the car though.Those are temporary...was in a hurry to get scoop tested/resolved...plus,I'm using existing valance bolts(2) just outboard of air scoop...I'll fab up better ones to work from inside...these were off the shelf,pre-drilled,etc...
In fact..I can make some from the 18 ga metal scoop I whacked !!!
Me ...get drunk ???
Hurts at my age....rich
