Inside and Out - civics with hoods that stick up when closed

I have been looking at alot of like "JDM" rides and meets from like everywere. And I noticed alot of these civics hoods stick up at the back near the windshield. Whats with this??

Here is a example

it's for "better airflow" :eek:

I think it looks stupid

MaD JDM y0!!!... aparently it is primairily for when you have ITB's that it is beneficial for

That was not even a minute sinceI posted this to your replymxs lol.

But I see what your saying, I agree with you...looks like the hood is off.

ya i noticed that a couple times in Honda Tuning and never new what it was for. Learn something new everyday.

I normally dont like stuff like that but I actually think it looks kind of sweet.

it's supposed to help venting of heat from the engine bay... only with the tiny holes in the front of our cars... I don't think it would do much besides create more drag

it is used by some hardcore drag racers to help with airflow on primarily boxier cars

your all wrong (mostly), the actual purpose in the beginning was to give under hood clearance for larger swaps if you don't want to hack into the frame of the hood. swaps like the K20 in some vehicles, H22 in other models. it can serve as a sort of vent, but not very efficient at that.

p.s. They use varied sized metal spacers via extended bolts.

i have seen them used on turbo'd cars so the heat can get out from under the hood.

Or you could do it the ghetto way and use washers. And I think they look stupid also.

washers are just too much of a hassle, you'll need like 100 of them, j/k

and some turbo'd cars do have them for venting purposes, but it's still not that effective, unless your ac is removed to increase the fresh air flow through the bumper and grille.

its true about the engine thing i did that to my old da when i swapped in my b20b it didnt fit so vuala

Exactly. I had a friend who drove a heavily boosted eg hatch with the a/c removed. Whenever he'd drive it for more than 20minutes or so, it would get crazy hot and you could feel it on your legs inside the cabin. He propped his hood, and it did an astonishingly good job at reducing the temps inside the cabin.

I'm sure someone will argue with here, but we've already got a thread full of that floating around here somewhere..

I've also heard people say that you can get a similar effect by simply removing the weatherseal in the cowl at the top of the hood. That's about 3/4" of extra airflow, with the hood staying at the stock position.

Very true. The same guy had that done as well.

I should dig up the specs on that beast

yeah, if the rear of the hood was already raised, then the wheather stripping is unneeded anyway, so might as well throw it out to increase the effect. i bet that would be an awesome defogger for your front windshield in the winter. lol :D
