It's right under your last post. As I am running the PWJDM CF intake, it does suck a majority of the air from the engine bay where the temp is high. As we all know cold air is definitely better, and any way to get cooler air is always better.

Oh, sorry. I didn't realize you held a master's degree in Aeronautical Engineering. Proof of this degree will definitely change my mind, until then It's just another internet opinion cluttering up this thread.Originally Posted by Doppelgänger
Just because my car is an NA civic, has no relevance to anything. The engine still produces heat, like any other and that hot air can be released from there by venting. Being on the track and constantly pushing the engine throughout the rpm range, will produce a lot more heat than daily driving. As I currently do not have a vented hood, this is a cheaper alternative.

Please stay out of this thread, if that's all you're coming in here for. It'll be much better without your negativity.
When i walk through my house, if i saw a cabinet door open or a faucet running, id instinctively want to close it. When i see a car with it's hood not closed, i get the same effect. I thought riding around with your hood open was only something house wives did after they tried to check their oil and forgot to close it.
I can tolerate the (lack of) style, but dont piss on my leg and tell me it's raining. The kid pawning it off as a performance upgrade is insulting to people's intelligence.
reduces "under hood" temperatures by 55%.... why? cause race car!

Saying the mod is ricer bullshit is just that, the mod. I'm not outright saying you're such a title and even went as far as posting up a nice explanation of why that is a "dumb mod" in order to help you (and others) understand what is happening. Did you even bother to read any of it? I'm guessing not. No, I'm not some physics major, but I have been around plenty of people who are qualified to discuss this matter and have learned enough from these people. Clearly, however, you do have your degree in this field. So please take your time in replying with factual data to prove otherwise.
Furthermore, that "article" is a fucking joke. I laughed quite loudly at their "data" and how it was "measured". They didn't prove jack shit. Oh so air temperatures in the engine bay were a few degrees cooler. That doesn't mean SHIT. You can have a snow-packed engine bay and air temps at -13*F and still have an overheating engine if there is no air flow over the radiator. News flash- engines aren't air-cooled. Engines don't give a shit what the air temperature is in the engine compartment. What about all the mid-engine and rear-engine cars out there with engines in VERY tight compartments with little or no airflow? Think about it. What matters is the ability to move air across the radiator to keep the coolant in the engine at a proper temperature. A proper test would have been much more in-depth and would have measured coolant and oil temperatures across a set of conditions using a constant and the variable. The bottom line is introducing air into the engine bay without it passing over the radiator reduces the heat transfer and the ability of the radiator to do its sole purpose- remove heat from the coolant.
Also, don't feel too singled out, I've had this discussion on a number of occasions...friends and strangers, and on more than one occasion, people have thought about it and realized the misconception.
Because I am hard, you will not like me. But the more you hate me, the more you will learn. I am hard but I am fair.
Lastly- I am NOT knocking on anyone for *needing* a way to make an engine clear a hood. I know there are a very few exceptions to this, but even in those situations I believe there is a better way to make it work. As far as sourcing air for an intake, there are proper ways to do that as well without compromising proper air flow- trying to cool the entire engine bay is not one of these methods. A well placed and isolated intake is not a hard thing to do. And to top that off, most gains from aftermarkets intakes come from flow and design over intake temperature. Yes cooler air is denser and can make a slight gain in power, but not as much as you would think. Detonation resistance is more of a factor. But let's not get started on pumping losses based on air temperature differences.
