Intake fixes, boost power?

yeah aluminum absorbs heat more than most materials, plastic is a better way to go and if you really wanted to you could even wrap it, though it wouldn't be pretty it would further insulate. Looks like a pretty clean install, even have the gasket for the hood, over all I like it. Do you have a scoop in the hood to get air in that box or is the opening between the fender and the home made box to allow air through behind the headlight housing? Ideally if you finished both sides to seal the box off from engine bay air and had a functional scoop in the hood would be great. Only other thing I would say would be ideal if making your own would be less bends from the intake manifold to the filter. Overall you have my approval.

this is how i did my intake
its all plastic and im workin on a heatshield tryed to make the bends as smooth as possible and bought a filter that had a funnel built in to try to get the maximum from the intake keeping the intake a little long will help with the torque in the lower rpms and we know these cars need that shorting the intake will help with engine response and shift the torque curve till later in the rpm
my vent in the making in the hood
need to clean it up but i did it quickly cause i like to

outside air, maybe in fender or below driver side headlight. Anyway it
still looks pretty kool.

The thing is... You want condensed air to come into your intake to gain power. If the air is colder, it is more dense. If the air is hotter, it will expand.
Air that is inside the engine bay is
A. Hot. put your hand on your valve cover/intake after running the car, it acts as a heater.
B. The air in your engine bay is already expanded from the running motor/moving parts and the fact that the air is trapped under the hood.
I am not an engineer but these are all things I have read/heard from engineers. Having a cone under the hood will sound nice, may produce better flow into the intake, but the temp/denseness of the air is bassakwards of what you want.

yes it is but the benifets are still there thats why theres heat shields and cold air ducts the hot air is already hot when its being sucked up so its already expanded thats why you take steps to insure you get cooler air and you keep that air charge cooled for every 11 degres you make your intake air temps cooler you gain bout 1 hp

Thinking condensed and expanded is great, it allows you to understand that the air once through the throttle body expands creating more air, so the colder the air leading up to the point is the more air once expanded. Ideally outside air is what you want, but a lot of people don't want to cut too much or even show that they have mods. By making a box that is able to be insulated from the engine bay heat, and sealed around the edge you essentially block off that hot air. Now you need to find a way to get cold outside air into that box and you will get much better results. If you use that silver insulation on the side of the box and a gasket around top and bottom of your box, then have a inlet of some sort to allow cold air you'll get great results.

that's why I like your general set up, you have a heat shield to help with that, you only open it where cooler air is coming through, and you used a gasket to seal the top. Granted could be sealed off more and letting only outside air in, but it still does a good job of it due to that heat shield. the air can even heat some, though not much as the engine is sucking it through, in the piping, the less bends the faster it moves and the less time it has to expand before the intake. I know you used plastic instead of aluminum to help prevent it heating up there, which is great too, could even use header wrap it you wanted to go extreme on it. Like I said before, generally I like yours, could there be some improvements? Of course, as is the case with most everything, even professionally made, but that still uses a larger majority of potential than most I've seen on here.

I agree with you both, THAT particular set up is pretty clean. Like you said Rich, it could be improved by air being directed in, but the fact that it is sealed off like it is makes for a pretty nice intake.
I was mainly referring to people who take off the stock intake box and fit a cone filter RIGHT there were the panel filter sat originally. Either way, for being a custom job that particular intake is pretty clean sirs

Water can't ever get there unless it at the top of the fenders! The air joggles under the drivers headlight which will separate the water and the air! Same source as the factory inlet scoop but larger now!
