Cold Air Intake 4 Mk3

[SupraSaver87]

I have a little theory there. I have NO CLUE if it would work well, or just again...make the car unique and look better. But here it is:

Would it be possible to run a metal tube just behind the stock front spoiler (The lower part of the bumper....houses the running lights) and then weld on some type of metal heat sink style stuff on the outside of the tube.

With this setup I could see there being a SLIGHT decrease in PSI, however the lower temp achieved by this system could POSSIBLY make up for the longer pipe, and if tweaked, I could see this working VERY well.

Are you talking about a turbo? because the intercooler would be doing more cooling than any finned pipe, Although it may help a little if before the intercooler when the air is still hot. And on an NA, Your not going to get the air any cooler than it is from outside, Because it would be the same air cooling it.

on a turbo that job has already been taken by an intercooler, but he might have something here, if you have the intercooler setup already you can put a heatsink behind it to shield it from the radiator heat, that can work right ?

but pple jus use a spraybar that basically d@mn near sprays frozen air in front of the intercooler helping it cool your system,

those things looks nice and functional, it looks like a nos purge when used

Blocking air from your radiator is never a good idea...Its far more important the engine get cool air than the intercooler. There is no need for a heatsink anyway, frontal air flow would take care of that.

LOL....

a real cold air intake uses a long tube that extends close to the ground since cold air drops to the ground and hot air rises (its science)

that's sig material right there....

Reminds me of the one part in Anchorman where Will Ferrell is explaining how men are smarter than women.

Can we understand heat dissipation and air density relation to temperature, first and foremost, please?

I made a heat shield for my subaru because the ecu was pulling timing from hot intake temps on a 90+ degree day in traffic.
It's made of aluminum, and ::shocked:: it works.

ever stand in front of a fire? stand close. feel the heat on your face?
Put your hand 8" away from your face, blocking it from the fire.
Does it block the heat?
now, do that with, oh, a piece of tin flashing. does it work?
do it with a shoe, a rock, a branch, leaf, piece of glass.
it reflects the heat.


The small amount of heat dissipated onto the intake side from my aluminum heat shield is maybe, MAYBE, 5% of what was originally surrounding the filter.
I need to conduct some tests with a thermometer, but according to the heat on my hand, it's an incredible difference, and I haven't seen the car this happy from intake temps since the winter.

for reference, here's the setup on my Subaru.

That is a beautiful setup you got going there...I like the heat shield. I think I am going to fabricate myself one once I get my K&N air filter, well its that whole system or w\e that you get. Cold air intake, all that jazz.....so yeah, maybe it will look as clean as yours....but somehow I doubt that.

[supra90turbo]

thank you suprasaver!
It's not that hard, though. All it takes is a cardboard template, some tin snips (not really recommended, as they leave rough edges and are a little hard to work with, but they worked)
Other than that, some good weatherstripping from the junkyard, a bit of time, patience, oh and careful hands.

not dissing you, and dont take the reply the wrong way

im kinda thinkin it workd for your subaru beacuse your engine bay doesnt looks as cramped as the supra, maybe thats why the hot air from the engine or other parts has enough time to cool down before it hits your shield,

not dissing but that a good job that works for your subaru, functional and looks good

if i do the same thing with the supra, one of the ends is gonna hit the radiator thats why i was hesitant to use any metal, cuz i was sure that it was jus gonna conduct heat, and dont for get that theres only a few inches of clearance from the intake and the engine, and the intake from the radiator

thats why next thing im gonna do is to move the filter jus behind to fog lights

[supra90turbo]

it'll work the same.
There's plenty of room in the corner to do that. It may take some thinking, and creative fabrication, but it'll work.

It has nothing to do with the "hot air cooling down before it hits the filter"
The heat shield redirects hot air away from the filter area.
The shield, and get this, actually shields the filter from heat!

Trust me, it works.

It works a thousand times better than putting your air filter above the manifold and next to the fan, where it gets 195* air fanned onto it.

nicely said... my idea was something like that but it was just tossed to the side... i mean what do i know, im just a kid...
