I finally got to test the hood design that I created. The photos show the Hood thermal sensors and the “antenna” Air sensor.

The sensors are set to record the temps in Degrees F and are in correct perspective, left is left vent, center is ambient air, and right is right vent.

The air is about 20 degrees above the ambient with the passenger vent being 5 – 10 degrees hotter. This is consistent and I believe that this is the result of the main cooling fans rotation. It is interesting to see how sitting in traffic the temps rise to about 30 – 40 degrees hotter because the heat is rising without the cooling provided by the cars forward motion.

Considering the size of the vents and the speed ( 88 feet per second ) of the air over the grills I have calculated the airflow thru the grill. It comes in at about 200 to 300 cubic feet of air per minute. This would be about the same airflow as that available from out heater vents on the highest speed position.

At faster forward speeds, the airflow would increase significantly due to a higher draft over the vents and the greater air pressure thru the radiator / faster fan rotational speed.

So this little ditty cools well, and the vents really shine when the car is NOT moving as the heat wafts up freely from below. At the track the cooling is handy when your waiting in line or between heats and the car cools faster due to the vertical venting of the under-hood area.

The hood has no insulation blanket as I did not need the weight, the sound muffling, or the thermal insulation effects. Hope this gets some others interested in the option of hood vents, though mine cost me only for the paint and some time / adhesive.

IT’S THE WEEKEND AGAIN< YIPPIE squared……..

WOODY

 

You REALLY go above & beond on everything you do!!
A real inventor, & proving your work..
A REALLY nice looking hood & works better then OEM also!!
JOB WELL DONE WAY TO GO WOODY

 

Woody! Does your creative mind never rest? That is an awesome looking
mod to the hood. So, are you going to have these fabbed up from Carbon
Fiber? Though I told my wife that I'd done my last mod, with the Devil Horns, I'm afraid I might have to break my word if this becomes a marketed
product. Fabulous!

 

Your looking at a steel factory hood, why waste the money, I just cut the hood and since my car is black I did a Matt finish for glare and other 'reflections'.

This was my first mod, its all in my gallery, look see at the projects there your sure to see something you like.

Weekend Woody loving life best as I can.................weeeee

 

You know, I do seem to recall that this was one of your earlier mods, now
that you mention it. So, you just cut two tabs in the hood, and bent them
down. Then fabbed the grills for the vents? How did you attach those to
the hood?

I must say, I'd have to buy a new hood to do something like that, as I'd
be too afraid that I'd screw up the cutting and have to buy a new hood
I like the recessed vents much better than I do a scoop sitting on top of
the hood. Those look good too, but the recessed look so much better in
my opinion.

You really need to market this idea. Maybe through one of the vendors
you've already worked on mods with? I know I'd be interested in buying
a hood that looks like this.

 

Woody - Where does the water drain when the car is parked and it rains?

 

I drove to the dragon in the rain, no problems.

THe ugly red hood is my fiberglas mock up and it is 1/2 hood wide so I could cut the vents into the mockup. Measure a mess of times and cut once or in my case 3 times. When I got it happy I marked the hood ( see the gallery).

Water just falls thru just behind the radiator causing no issues after a year and such. Not hard to reproduce but the first cut was more hectic measuring top bottom top ,,,,,,,,,,,,,,until I was happy.. The strakes are retained as a stiffener and there are braces so that nothing flutters when the wind blows past it all.

I like it as it is a negative hood and meets the intent of the law in VA. No pop up scoop to get attention and it uses a venturi effect to suck the heat, but vents heat when parked nicely. See it at Carlisle again this year, coming up soon..........yippie road trip again.. Be Well

Reminds me of Dr. Emmett Brown

X2... I'd buy this in a heartbeat.

 

Woody, you and I spoke about this at the Dragon. I think you did a fantastic job and can start on mine as soon as you would like, you still have some of that radar absorbing paint, right??

 

You are awesome Woody! Keep up the great work, I love reading everything that you do!
