thought i would share it with everyone.

when the air goes into your engine compartment, where does it go after? the only place it can go is down under the car.

why not modify the cowl under the back of your hood to let the air go somewhere other than under your car?

(hint, heat will exit there also)

 

45 people look no one says anything, no one has an opinion or anything constructive to say hahahaha

 

yeeeeeeaaaaaaaah, i got nothin'

 

Why you get a heat extracting hood...

 

this is like making a heat extractor without changing the outside of the car. just a diff way of doing things

 

im cnfused. it sounds like your talking about a cowl induction hood or a heat extracting hood.

 

under your stock hood there is a black plastic piece that goes along the bottom of the windshield, there are ways to modify it to make the entire structure act like a heat extractor

 

......... This thread is fail........ If you want air to leave other than under the car buy a cowl induction, heat extractor, Or other type of hood... will fix your problem...

 

drive wit the hood off?

perhaps?

 

well, too many posts in here. Time to give us the answer.

if you take the whole thing off you risk getting rain down there, so I know that's not it.

 

I know what your talking about. The solution is not a new one look here for the honda/import boys solution.....

 

if that's what it is.....i'll pass. not worth a couple degrees to look like you were in an accident or your hood is broke.

 

lol thats why the import boys do it and not us....

 

A cowl induction hood works because there is a high pressure at the base of the windshield and it forces air down into the engine bay, so is this going to let air out from under the hood, or shove air into engine bay?

 

I've heard of big boost Solstice and Sky's modifying the piece of trim that runs along the bottom of the windshield for this purpose.

 

x2. I'll keep a little bit of extra heat in over having my hood aligned all funky like.

 

its just an idea i was throwing out to see where it went. ive got plenty of custom one off stuff done to my car im just letting someone else in on an idea, just sharing a bit, alot of people do it, just something to think about but apparently no one hear likes ideas hahahaha

 

no the info was appreciated, like you said, it's nice to throw it out there and source everyone's brain. there might be an aerodynamics genius in the house present that can enlighten us on how the airflow over and into the engine by would work..... you never know.

 

thats all im trying to do but it seems like more trouble than its worth hahaha o well

 

I don't think ducting heat down would be as easy as ducting heat up since it rises naturally.. hence the whole hood vent craze.

I do know though that some vehicles are designed for specific hood/underhood configurations. These encourage proper airflow through the intercooler, radiator, and engine bay in general which helps cool things down. Aircraft are the same way. If you take the cowl off an airplane or change the plastic/rubber ducting and idle it, it may overheat. You just don't get the airflow into/through the places where you need it.

The plastic piece that sticks down under your car's front bumper is a similar device. I've actually heard of people's engines getting hotter when these pieces are broken off/missing.

 

do you know how fast heat rises in the atmosphere? not very fast. maybe a couple miles an hour. Do you know how fast the air is flowing into the engine bay? well, how fast is the car moving? At almost any speed, the fact that heat naturally rises is a non-issue when dealing with aerodynamics. HOWEVER, i do still agree that it would be better to make the air go over the car instead of under it.
