'ram air' idea... need input

i had an epiphany at work, probably very stupid, but an idea nonetheless...

is it possible to use a gutted TMIC on an NA (with a TII hood) as a ramair? gut the ic (remove the fins) and fab a bottom to it that goes to the intake piping? for a true ramair with the vented hood?

like i said, probably stupid, but worth an ask, right

sure it's possible but most people are not creative enough to even bother and try it,

with the bends that are necessary though i don't know how much velocity the air will actually have by the time it actually gets through the airbox and MAF to be worth it though...

I agree, but you never really know until you try it. IT does sound like a good idea and it is very possible that it may work. Additionally, it would be pretty cool to see an intake like that. I say go for it

well most of us just vent the RF headlamp cover and use an open element filter and box it in, i would tend to think this would be easier to do up and net better results but this could do it one up but would be tough unless you used the stock airbox as an inlet for the filter or you could make the TMIC fit a filter cartridge but it would get dirty fast...

Mounting the air intake directly on top of a stinking hot engine is dumb for exactly the same reason it's dumb to put an intercooler there. Do I need to elaborate further?

The whole point of ram air is to place the air inlet in a high pressure zone. Air doesn't actually "ram" itself in due to velocity but rather the boost created by higher pressure. The air inlet on the center of the hood, besides being directly above the engine where the heat is, is in a low pressure zone of the car. This will not ram in any air at all but will actually breathe less air ultimately even though some air seems to be flowing directly into the inlet. The highest pressure zones at the front of the car are the grille opening and at the base of the windshield. Keep the intake piping openings in these areas for best results. The low pressure zones on the front of the car are on the hood and the upper half of the windshield. What appears to work from a visual standpoint and would seem logical doesn't always work that way. Air is funny stuff.

No your not, your creative, you just didnt happen to know the high/low flow zones and ****, not really common knowledge.

Anyway in reference to the grill being a high presure zone. I have this thing from weapon r . i know its a bit of a ricer company but the product makes sense. The filter sits in the stock location and ha a thick plactic sheild around it, the sheild had a 2.5" flexing pipe attached which leads to a rectangular inlet which is placed into the grill. People laughed when i called it RAM air, may not be perfect but better than sitting lonely in the hot engine bay.

I was thinking of fabing a big pipe to go from the stock airbox to the front grill, lots of cool air there, and hig pressure, but you would need to cut a bit of metal.

Another prob would be actually mounting the IC up there. The TII mani has prvisions for the IC, but the N/A mani does not. Even with a TII hood, the IC may not clear.

Damn dude. Can you be a bit more negative next time?

I doubt the IC will fit up there.
