i was wondering if the vent holes on the '94-'98 mustangs hoods did any good in keeping the engine compartment temps down? if so i was thinking of drilling out some holes on the little honeycomb panel thingy in my hood all the way through the hood and then cutting out a peice of the underlining right underneath the holes. if it doesn't vent any heat it will at least push a little bit of air into the engine compartment. so is it worth it?

I would not put random holes where they are not suppose to be. Ford designed the hood so the compartment temps will never be too extreme. Just like Mitsubishi eclipses have a small raise in their hood. That’s because that is the hottest part of the engine. If your looking for decreased engine compartment temps go with an aftermarket hood that is functional and looks good.
In some cases an aftermarket hood can raise horsepower and torque this is because your air cleaner is always seeing hot air thus by reducing compartment temps = more power. However the increase will not be substantial. Replacing the thermostat is very helpful to your engine and i would recommend one. If you get one make sure you also get a new Temp sensor as well.

yeah, I wouldnt randomly drill holes in my hood if I were you. It wouldn't make that big of a difference, there's not a bottom of your engine compartment, so what good would some tiny holes in the top of your hood do?

lol no, not quite. thats where the timing belt cover goes. the timing belt is only a factor for the turbo eclipses/talons because of how the GST/X engine bays are reversed from the N/T versions. the turbo versions have a completely different engine(4G63) than the non turbo(420A) and the timing belt is there. in no way does it get hot, now, the front part of the hood is a different story, theres a turbo under there, thus why mitsubishi made the vented evo hoods like they are, to get more air to the turbo when its not moving.

show me some pics lets see them. I have been told by numerous people that it is the hottest part of the engine. I dont see how a timming belt cover would be so high above the valve cover that the hood needs to be raised in order to clear it.

The Eclipse Turbo's last year was in 1999. Numerous problems with the Turbo such as frequent overheating.

Very sleek this year and not as 'animated' as 99 and previous models. The ever present bump on the hood is smaller as is the rear spoiler which grew to great heights in 98.

Eclipses run hot from reading numerous websites and wonder why the buldge grew to hudge hights in 1998

reminds me of Homer with a pick axe as he slammed it into the hood of his car, making holes everywhere. It makes the car go faster!

scoops and vents relieve heat.
exactly Dom, just cuz there is an open bottom of our engine compartment doesn't mean that heat is going to escape through there cuz everyone knows that heat rises, it doesnt sink.

i find this post really funny. whatever you do, don't drill holes in your hood.

within a few weeks of me getting my stang (my first car ever, i was 17), i wanted to make "ram air" and did what you implied. i had to buy a hood scoop to cover the hole. leaves, water, crap can all get in there. if you want to help cool your motor, change to a 180 deg thermo, add some water wetter to the coolant, and wire in a manual fan switch for the track. i'm still trying to get the damned fan switch to work.

I'm not ignorant. I know heat rises, but driving down the road or on a track, there will be air moving around under the hood.... :rolleyes:

i really want to know where you got that from. the bump is the same height on all 90-99 eclipses and talons. whoever wrote that is a complete moron. the bump has nothing to do with the turbo heat. its to make clearence for the timing belt. lemme go take a pic.

actually thats why the evo hood is how it is. while driving, a vacuum is created by the wind moving over the contours of the hood. thus, when they opened the front of the hood on the evos, the vacuum sucks the hot air out of the front of the engine bay, where the turbo is. it works very well. but a n/a car does not need huge vents in the hood, nor a turbo car, cause its gonna be hot as hell anyways in that bay, a vent will only help a little.

oh and they were right though on the 98 spoilers, some turbo versions got the "turbo" wing which is like 3 inches taller than the stock spoiler. but it looks good IMO.
