new hood project

[myrodr]

well i started with cv hood+ 72 grand torino sport hood to make one! welded it myself did ruff fill. hood is now at my painters shop. hope to post pic s of car when done.

[guspech750]

Oh yea. Looking forward to seeing the finished hood!!

Can't wait to see it. I think when customizing a Marauder there is a fine line between classy and "too much". I love to see classy.

[myrodr]

thanks for the post on my project. i think the lines of this scoop match well with hoods lines

[05crownsport]

Can't wait to see it...true hot rodding stuff.

[Mercguy04]

looking forward to this project. I hope it come about.

[myrodr]

Here's some pictures I took as I was fabricating my hood. Hope it gives you a good idea of how nice the lines compliment each other.

[guspech750]

Looking quite cool!!

I wanna see on the car

[Guittard22]

sweet looking hood :) How much you end up spending on the 72 grand torino hood?

[myrodr]

got lucky paid $50 for torinio hood under side was very rusty,

[bugsyc]

I like it.It's going to look great.Waiting for completed pics....bugsy

[justbob]

As picky as I am... I think I love it!

[TAKEDOWN]

Can't wait to see it on your MARAUDER!

[FastMerc]

That looks pretty dam good so far!

[massacre]

Yeah, that's nice work!

[Black_Noise]

not bad, but what happens when it rains? Free engine wash?

I am waiting to see this on the car, always like seeing different options of scoops on an MM

[Mercguy04]

I love it.
More & more photos please

[Pat]

OP didn't mention if it's supposed to be a functional scoop, although the Pic's would suggest it is. What function(s) do you envision? The inner frame structure has been deleted, will the metal scoop provide the missing rigidity?

I do like the design.

It would be interesting to see what intake tract modifications are being added to utilize the air coming in the scoop. Otherwise it will have the same effect as the cowl induction hoods, cramming more air into an already high pressure engine bay impacting cooling efficiency.

[Mercguy04]

If you could figure out some way of draining the excess water, like rubber tubbing
somewhere near the wiper motor assemble running left and right, that would help
with some drainage issues Assuming the hood is for show.
As to the use of the air intake. There was a post a while back about a guy that made a
flap closing switch that closed the cowl induction
.

Hope this suggesting is helpful. I don't know how you are going to route the air into your CAI, That is a whole other issue.
I certainly don't assume you don't already have some sort of plain in the works
already. I am just making suggesting, I hope you don't mind.
Thanks

Hood with no holes, no air coming in or out. Hood with holes, air coming in and out. Yeah I could see it impacing cooling efficiency. POSITIVELY. Heat rises, it's science, I don't have time to explain it.

At a standstill this is true but not while the vehicle is in motion.

Once the car is in motion a high pressure zone is created at the front of the car and at the base of the windshield. Air is drawn through the radiator due to the air passing from the high pressure zone in front of the radiator (notice the plastic flap under the support?) to the low pressure engine bay. Once you add a scoop to the hood catching air or an opening in the rear of the cowl hood then you are increasing the pressure in the engine bay and reducing the flow of air through the radiator (along with increasing front end lift).

Ever wonder why the GT500 uses a heat extracting vent and not a scoop or cowl hood? It's because the air passing over the hood creates a low pressure zone which draws air out of the engine bay increasing the flow of air through the radiator improving cooling system efficiency.

It's science. :beer:

The inner frame structure has been deleted, will the metal scoop provide the missing rigidity? The inner frame was removed,to install inner structure to match hood scoop. I may make this a ram air later,if cooling efficiency is reduced i can use block off plates that ford put on the scoop. i do like knowing others concerns ,but i did think about all the things that the change could cause.

You seem to be getting upset and I don't understand why. :confused:

The Super Snake hood you are showing is not open at the rear and the front scoops lead to four very small holes over the airbox.

The only really functional parts are the vents open to the low pressure zone on the hood drawing air out of the engine bay.

Good afternoon Sir.
I tried this system on a Cadillac STS V and the problem I incountered was there was not a system in place for the rain to go except into the engine
compartment, on the eletronics. Good thing they were moisture resistant
I finely had to remove the hood as I was not able to deal with this problem.
The only other way I can see is to look at a MB 500SL openings and see how they are dealing with this issue. See photos for problems and a possible resolution. Maybe not.
The other issues are not involved as you can see

This may be one way of dealing with this problem.
It is only a suggestion. Mod it may be and option.

I agree Mr. Bolsen,
But where the covers are placed, they are not in the same place as would be the Original hood inlets, nor were they placed in a position for the Caddy.
That is why I replaced the hood. It went to AZ Not a lot of rain there
for the most part. The Red hood would have the same problem.
The Caddy Hood was built in California, again not a lot of rain there.
The 03 Mustang hood did have a servicable soluation for this problem.
But was restritive in it air intake that was the problem with that Mustang.
the new Snake is very useful. Would something like that be useful for
our applacation, I think I would need to study it and then decide if it would
work. I think it would. Thanks for writing

BAM!!!! :lol:

[Siege]

I understand your science, for what it is worth. Using air to draw out air. I've de-watered flooded compartments on ships using the same technique, except with water. :D

What we're really talking about is Bernoulli's Principle http://en.wikipedia.org/wiki/Bernoulli%27s_principle

http://upload.wikimedia.org/wikipedia/commons/7/78/VenturiFlow.png

The faster the flow of air the lower the pressure and the slower the flow the higher the pressure.

For those of us that are supercharged and have heat exchangers mounted in front of the radiator there are also gains to be had from sealing the heat exchanger to the radiator and adding a heat extracting vent on a low pressure area of the hood. Increased airflow through the heat exchanger will translate to lower temperatures.

Here's a good diagram of the pressure areas of a car:

BAM!!!! :lol:
You know what's really funny? While researching the Super Snake hood some owners are reporting that the 2011 hoods don't even have the front scoops open. Talk about form over function! :lol:

We used eductors like this to empty flooded compartments. Water goes in at about 300 psig at the supply end, pulls water from the flooded compartment thru the suction end, blasts it out the discharge end. I've also de-smoked spaces using this method when power is killed in that section of the ship.
Memories. :beer:

that is not a super snake it is a kr and it has a functional ram air and heat extracting the gt500 just has vents

[Siege]

I haven't been able to find any pictures of the underside of a GT500KR hood but as long as it's sealed to the airbox then it is functional and won't disturb airflow in the engine bay.

While looking for a picture of the KR hood I did come across this about the Super Snake hood.

http://www.teamshelby.com/forums/index.php/topic/71913-well-i-guess-this-answers-the-2007-2009-functional-hood-question/

Anyway, sorry to derail the OP's thread. Definitely excited to see how it turns out!

yes the kr is sealed with the outlet going in to the sealed air filter area the hood air box also continues to the vents where it draws the hot air from the under hood area out from a couple 2" holes in the air box

[myrodr]

Got the hood back from the painter Love it!!!! Hope you guys enjoy viewing it as much as I do having it on my car!
