Today I wrapped up scoop test..no gain/loss at lower speeds as expected..
I removed scoop and took license plate and mounting bracket off....I had no idea that it was closed off behind bracket on the 78...
so I cleaned/painted plate bracket/Scoop and put everything back...
I'll run with the scoop for awhile for the 4-5 degree reduction..

Thats a great Idea!! I wonder if building a scoop across the entire valance panel would make an even greater differance in cooling.
I'll have to fab something up to test here with the forecast for 100*+ for the rest of the week.
Great work rihwoods

Just got back from running at 70 mph with A/C on...temps leveled out at 200 and just sat there...so back to the drawing board to redesign this turkey...it's the mounting I have to work out..don't want to drill holes in valance..also,I'd like to make one from plastic..
Here is pic..hard to see temp gauge,but it is straight up...

Went to Pep Boys this morning and came and noticed I almost whacked it..

Great project! This is fun...I can experiment with the 78 and use the 69 for the pucker factor... Curious now about this "ram " air effect...and running the original A/C condensor....the 78 C/B is 5 years old...think I'll go ahead and re-set calibration on the clutch fan....

Way more than I expected. Not sure why it is cooling it off that much.
Drove around Sunday morning and could never get the fans to come on. Even sitting at stop lights. Average drop was 10 to 25 degrees. I'm going to have to plug this thing in the winter.

I'm thinking about making it out of the remaining pieces of the original hood, and glassing it to a used valance panel. I'll think of something.
You may have one of the best ideas for cooling down our cars yet.

Maybe I should take those 2 10 inch electric fans I was using for the radiator and move them to the two openings behind the front wheels to help remove hot air from the engine compartment?????

I'm just thinking back to Rich's "tuft" tests. At speed, his car (okay all our cars) is taking air IN from:
the cowl
the side vents
the grills/front/below the spoiler (obviously)
So where is all the air GETTING OUT? Other than a couple hundred CFM that's getting inhaled/combusted, I'd guess that most of it is leaving through the bottom of the engine compartment, then below the car and out the sides??
I dunno, is all this getting-more-air in just increasing the high-pressure area under the car? That can't be good for high-speed stability/aero.
