thats exactly wat i said but i just didn't go throught the detail like you did

I just bent the end of my hood today, from all the ice.

If it was spaced, i wouldnt have, lol.

someone should put an IAT sensor in that area, and an actual test to see if air is flowing IN or OUT.

with my old ITB setup, years ago, we datalogged quite a drop in IATs after i spaced the hood up 1''.

it does and is proven to work. please research a bit before you state things as fact. it looks fine sometimes, sometimes people dont like it..i understand that 100%

with my new setup, i HAVE to do it (F-D, engine is just too high)


wont bother me a bit. looks fine IMO

your explanation makes no sense at all. air flows over the hood, then over the windshield and so forth. air does not hit the windshield and bust a 180 degree turn into the hood. wtf are u talking about? haha.

ever seen a wind tunnel test? ever wonder why the hood at the oem position is already slightly tilted up to help flow with the windshield?

in any case, tilting the hood a bit up allow hot air to seep out. why? hot air rises. durr? to do a test, after running ur car, pop up ur hood and what do you know, hot air rises to your face.

now, add some spacers, run ur car hard, park ur car, and place ur hand over the back of the hood, what do you feel? hot air seeping out of the raised hood.

simple phsyics people. don't over think it.

i did it and it works. its ugly yes, but shlt, i rather have it ugly then my car over heating. i rather tilt the hood, then having a dark vador style vented carbon fiber hood.

if your car is going to overheat cause you don't have hood spacers then you might want to check wats wrong cause a car shouldn't overheat over an inch of tilt on your hood

actually your not really 100% correct. how do you think all the little stupid leaves and crap sit down in the crevise of a dry windshield (and they will) when your cruising down the highway. you could lift them right out, or blow them out sideways with your mouth pretty easily sometimes..but driving around holds them down. there is positive pressure at that point, pushing down into the low spot between the windshiled and the hood..its "simple physics" as you put it. cowl INDUCTION really is what they say it is. more air goes over the windshield... but some is forced down.

Its retards like you who put giant wings on their cars and 'know' they'll get mad-tyte JDM downforce to let them drift like crazy.

<U>Do yourSELF a favor, and test it.</U> Put some washers under the hinges, then tie some little strings (plastic-bag thickness, 1/8"x2") around the area, then go cruising. You will see them flop all around until 15-20mph, in which case they'll start reverting back into the engine bay.

If you want another example that you'll love to mistakenly call '***-backwards', look at the muscle cars from the late 60's and early 70's. Cowl-induction hoods weren't just for looks or to fit twin quads on a high-rise manifold - they actually worked. Air gets pushed in there. People who don't understand it are usually thinking of how liquids move, not gases.

saw an arguement about this on the del-sol and civic ek h-t furom up above about it not working. my car has been getting hot under the hood latley as well so i decided to give it a try. IT WORKS! it looks stupid but it works. durnig stop lights after a hard drive my temp stays normal. so thats how its gunna stay at lease till i buy a hood with a vent on top.

Yeah, just like mentioned above. All those old muscle cars and even current drag cars, don't have the cowls on the hood for looks. It does help whether people admit it or not. Everyone is so quick to yell rice even though some things are truly functional. It has been proven that WHEN DESIGNED RIGHT body kits improve aerodynamics but these days body kits are rice. Rice Rice Rice STFU.

The only thing people are failing to consider is cowl hoods are usually isolated from the engine compartment, therefore the engine is creating suction in that area and <U>drawing</U> air off the cowl. It obviously doesn't work better than a normal scoop either considering the most refined door slammers in the world (pro stock) all have normal hood scoops.

Furthermore, the engine bay of most cars is going to have positive pressure due to all the air trying to come in through the radiator opening so it's going to take a fairly significant amount of pressure to overcome that.

Then again, many cars (my own included) have a air vent that to the best of my knowledge draws air of the cowl. At 60 mph there is a decent amount of air coming through there with no fan assistance.. that doesn't happen without positive pressure.

I really don't know which way the air flows, just throwing some things out there to think about. If the air is flowing either direction it'll cool the engine bay obviously and it is doing that so who really cares?

What I meant by that is how easily air changes direction. The only time you'll see an absolute vacuum in real life (as in not in a chamber, etc) is when something suddenly accelerates to a few times the speed of sound, or something moving the speed of sound suddenly creates a huge blockage. Air will always fill a gap, and move into it quickly when its a lower pressure area. Water will splash out of the way, simple enough to watch a boat cut through waves. With a turbo car, you have enough blockage in the grille to mean air won't flow into it all that fast, and the way air flows undeneith a mass of air not in motion, you get suction pulling it out the bottom as well.

Only way to tell is do the test I described. I do know that they guy who made that Kimini mini-cooper h22'd car did it with his hood, as he put a big hole in it. Air moved easily out the hole, but then started moving sideways and even forward in some spots due to the pressure zone at the windsheild base.

I'm not sure if this has been said or not, but there is no air being forced into a cowl induction hood. The cowl induction hood simply takes advantage of the swirling of air where it hits the windshield/cowl area. Air there is denser and is sucked through the cowl induction part into the intake of a car.

1st of all, i am wingless..

and u sir are a dumbass. I actually saw a discovery channel special on the old muscle car. and the reason why the vents were faced backwards, was for the looks. haha.

i'll try to find a link somewhere. and please, stop pulling information out of your ***..... wind goes over the hood, then over the windsheld.

putting spacers on the hood, allow heat to dissapate out the raised area.

so however it works, the right explanation (mines), or the wrong one (yours). it doesnt matter. it sill cools down the engine.

ur explanation makes no god damn sense whatesoever. "wind hitting the windsheild, and then making a 180 degree turn down the windshield into the hood. hahahahahahah.lol.

the windshield is angled at a way to allow airflow OVER the windsheild then to the top of the car.... Again, look at the windtunnel test... I really don't see any air hitting the windsheild and reversing back into the hood.

god this guy is a ******* idiot. you go do some damn research. tell them to add some hood spacers and then go do the wind tunnel test again. the reason air isn't going back into the hood in that video is cause its sealed off you dip ****. your probably some stupid *** high school kid that thinks he knows everything.

same can be said about you dumb ***.. even if there hood was tilted with spacers, air will still flow over the windshield.. its common sense.. Something you obviously do not have.

i dont know who the F else belives that air will hit the windshielf, and instead of going up and over the windshield, it will "bush a bltch" and head backwards against AIR FLOW.

HAHAHA.. Just admit you were speaking out of your AZZ and were just making up shlt to sound like you know something. Just look at the wind tunnel test. there is no way in hell the "air flow" will bust a 180 degree against air flow and against the law of physics..

Its like throwing a ball against a waterfall and expecting the ball the climb up the waterfall.

why dont you do urself a favor, climb up the highest mountain, and jumb on the clouds. tell us how bouncy it is.

air does go inside the hood, take for instance your air vents, where do you think the air is coming from that you are feeling going inside your car? the vents are clearly tucked away under the hood.

nobody said ALL the air will go down... most flows nicely over the windshield. BUT. there is a pressure area at the base of the windshield. this is a true statement.

there is positive pressure at the back of the hood, causeing air to want to enter that area. there is also however, slight positive pressure under the hood at speed, causeing air to want to escape.
