ok ricey or not

ok is it ricey if i add a stick on hoodscoop to my car and cut out undernieth it.... reason for this is is after 30 minutes of driving my intake tube even gets too hot to even touch......

In reply to KATYB:

Only ricey if it doesn't function

Agreed

Horribly, horribly ricey.

yes

ricey

Who cares? If you're doing it for a reason then it's okay in my book.

Always seems like the devil is in the details on things like this. Finding something that looks okay, positioning it well and doing a good, clean installation usually make a plan come together. Only really looks ricey when cheap, badly made and designed stuff is randomly stuck on with no rhyme or reason.

so ricey even tho there is a function to it? even with the cai my air intake temps are climbing into the 120 to 130 rang.

ok in all truth also i will prob not stick it on but more epoxy and blend and paint the hood in a vpattern

What car is it? And what will the scoop look like? I would use a NACA duct.

It's going to "look" ricey to casual observers, whether it is functional or not. How about ducting cold air from somewhere else, like the radiator support or fenderwell?

Right now, where you live, aren't the ambient temps reaching 105? Meaning, a change to 120 isn't that much and 130 doesn't seem extreme.

If you want to do a hood scoop I think something that does air extraction, like a "cowl hood" would be better than something forward facing. There are also vent sections sold that would probably work well and be less noticeable vs. a scoop.

That's my 2 cents, no hands on research done by yours truly.

There is more than one way to skin a cat. There are probably better ways to get the intake temperature down with out having to cut into your hood.

yes reaching 105... but these reading were taken last night around 1 in the morning when it was 82 outside.
93 civic its my 03 mazda6 s... i had yet to decide on the scoop... but was thinking one around 18 to 22 inches wide. 1 inch tall opening. and putting a naca duct on each side. air filter intake is in the drivers front bumper right behind the foglight.

I don't think it will make a huge difference unless you seal the intake tube to the hole. I don't think just expecting the cold air to get its way to the intake is going to work out.

weather sealing strip has already been removed at back of hood to help with cooling. and headers are wrapped just so frieking cramped in there.

tuna there is a plate separating the filter from the general engine bay.... 1/8 aluminum with rubberfoam sealing to tube.

I guess the question I'd have is if it is better to pressurize the under hood area with something like a NACA duct, or extract existing air from the under hood like what I mentioned. I don't know which is better. Maybe both even.

cold air makes its way to the intake... problem is heatsoaking of the manifold and intake tube.

Why is the tube hot? If it is pulling fresh air in there should be a cooling affect. I would consider a low mounted air inlet that is directed to cool around the air intake tube looking something like this:

From CARS

which is pretty much how it is. sealed from engine bay. air drawn in fron fog light and ventings in the wheel well. well its not perfectly sealed but deff blocked off...... trust me..... if you see someone with a mazda 6 v6 out on a hot day after they have driven a bit open the hood and touch things...... becareful touching the hood it sometimes gets hot enough to burn you. even without sunlight.

ok im gonna experiment and see how much cooler things get with the hood completely off.

FTFY

I've run into this with HVAC ducts in construction equipment. Sometimes we need to route them through the engine compartment.
Before you go cutting up your car, you need to first measure the "air" temp at the inlet and outlet of the intake tube. Just because the outside of the tube is hot doesn't mean the air temperature rise through it is significant. If you are getting a significant temp rise, then you need to insulate the tube. That would do the most to reduce temp rise in the duct. If you're set on cutting sheetmetal, you first need to understand that this would cool the engine compartment, not specifically the intake tube. If you still want to go that route, you need to know if the engine compartment is in a positive or negative pressure under the running conditions you are concerned about. It will most likely be in a positive pressure under most conditions. If positve, you want to provide a way for the hot air to escape. If negative, you need to find a way for colder air to enter.
