Phantom of the Opera
In the other threads with Skunk and BJ I said I would tape some pennies across the rear of my BB add-on repro hood scoop....
the scoop has the entire underside of it hollowed out from the OEM hood, so it's all hollow, somewhat similar to some hoods I seen at car shows....but not identical....
I will stick pix of the exact install on my site when wife gets back and processes them.....
The rear slot opening of the hood bulge is 1.75 tall and ~18" wide.....it is 5.5" from the rear edge of the hood, the car is a '72 and so has the stock wiper door and grill panel.....
at ANY speed up to 110 the pennies taped and suspended in the middle of the opening, just sat there totally vertically on average, just an occasional flutter back and forth just as if doing 20 mph in the hood, there is essentially NO AIR coming up from under the car giving any appreciable lift on that hood...none what so ever.....
pix will include a shot of the front of the car....and with the pennies as hung for the test, and the underside best as I can pix it.....
I can't understand why there is insignificant airflow through that scoop, and would have to be also about nil along the back edge of the hood also, where that gasket I don't have is supposed to be.....
:shocking::beer:
OK, took pix yesterday, and just put them on the site, 4 recent additions.....
