427 Cobra hood scoops

[my427cobra]

Hi Jdata. Yup.

The static tuft test will at least visually tell me if the fans move air out of the fender wells/vents while the car is at a stop.

I know it does because as I said , while sitting in the driver's seat I can reach my hand forward and feel the hot air coming out the vent.

The temperature testing is more related to my plan to install a hood scoop in a month or so and see if the scoop contributes anything to cooling the top side of the motor.

I'm working on a couple of ideas to mount a camera to capture the tufts on the hood. Probably a camera mounted on the top center of the windshield frame.

And to capture the tufts at the vent, a camera mounted to an old wind wing that I have.

I'll use yellow yarn which should show up very well against my Rangoon Red paint color.


Cheers
Greg

News Flash: Tuft testing update!
I hadn’t really thought about doing any tuft testing quite so quickly, but it was a beautiful morning here on the central coast so I was headed to the Pismo Derelicts Saturday morning car show.

So yesterday I taped some yellow nylon string ( hereto : The Tufts) to the top inside of the side vents (that is inside the engine compartment, not on the outside of the fender).

Four tufts per side vent, one tuft per vent vane. I made the tufts about 6” long so they would be visible if blowing out the vent.

I did this initially to do a static (car at rest with the engine off) fan test to see if the puller fan on the engine side of the radiator would push the tufts out the vents.

It did but weakly.

So I fired up the engine and that’s what the fan needed. Amps.

The tufts now fluttered out the vents.

Here’s a pic of the tufts on the inside of the vents.

This morning I headed to the car show, only about a 10 min ride from my house and enjoyed a coffee and a chocolate buttermilk muffin. It’s important to keep your energy up during such critical testing.

After a couple of pleasant hours meeting with friends, car guys and looking at a lot of fine rides, I headed off on my usual 2 hour ride along the beaches , to land’s end at Avila Bay and through some winery canyons.

Then I remembered, the tufts were still taped inside the vents.

Well, I leaned out the driver’s side at about 45 or 50 mph and low and behold, the tufts cometh. They were waving at me as they fluttered out the vents and that was with no fan on.

Picture to prove it. Sadly , NO. For the moment you’ll have to take my word for it.

But yesterday I was experimenting as to how to take pics of the side vents.

My idea was to mount my digital camera or GoPro to an old wind wing and take pics that way. But the angle wasn’t right. And the camera mounted to the top center of the windshield frame wasn’t the right angle to take pics of the hood tufts once I mount my hood scoop.

So back to the drawing board, or beach as it turns out.

While driving back past the beaches on my way home this morning, I realized my problem.

I was thinking too old. The young kids on the beach were young.

And Eureka. I saw the solution: a SELFI STICK!!!!!!!!!!!

A selfie stick could be reached along the side of the car by a passenger to take a picture of the vent tufts while the car is moving, or by me on the driver’s side if I’m stupid enough. And once my hood scoop is on, a passenger can use a selfie stick to reach over the windshield and over the hood scoop inlet to take pics of the hood tufts.

Stay tuned.
Cheers
