raised hood

[91CRXsiR]

im thinking of adding some washers to my hood bolts to make the hood a little higher so i can get more hot air out of the engine compartment. what is the safest/best way to do this? would i have to take off any weather stripping?

[sykikchimp]

that's gonna look like shit.

[tnord]

do you have a turbo or an SR? if you don't, then heat really isn't that big of a deal.

if you don't have either turbo or SR and still want to do this, please explain to me why.

[boosteds14]

dont turn into a ricer
it is so gay

[sykikchimp]

to be constructive..  

The better way to help remove hot air from under the hood (say if you did have a turbo, or something) would be to invest in a Cowl Induction hood, or buy a hood with vents in it.  The purpose of both hoods is to creat a low pressure zone around the opening the will essentially suck the hot air out of the engine bay, and bring air up through the bottom of the bay.

If I havnt told the board before, I was (and still am partially) a Toyota Camry owner. I posted on Toyota Nation for quite some time. I thought it would be different here, less flaming a more welcoming bunch of people who hold back their critisisms and allow people to make mistakes. Wow, was I fucking wrong.

1. i like the look of the hood slightly raised i prefer doing small things to my car rather than modding it w/ body kits and etc..

2. i don't see any downside of this performance wise if anyone has one that would help.

3. sometimes when i take the car on hard runs i have to turn on the heater to draw heat from the engine and it gets really hot in the car so if this would help so i don't have to do that why not?.

... i'd rather not get aftermarket hood because i don't want al those vents and stuff looks don't suit my taste . i like the plain look. because my car is black the little gap wont be very noticiable i don't think.

oh and the comment on rice . thats really funny. rice = anything that you do to your own car thats not stock. am i right?

If your engine is overheating then some thing is broken, raising your hood isn't a reasonable fix. If it's not overheating your just wasting time and making your car look goofy.

[S13CRAVE]

na man, rice is different than that. &nbsp;if i put a new exhaust on my car that looks and sounds good and is good for performance, it isnt stock but it isnt rice. &nbsp;but if i went out and bought a bunch of APC stickers and a double stacked wing without any sort of performance benefit, that is rice.

Don't forget those mufflers made by hyamiya or whatever

[240meowth]

while u r @ it, &nbsp;extend your fenders furthur out, so you won't need the z3 fenders for vent in the bay...

ok ok, enough sarcastic comments. &nbsp;but raising the hood like that isn't safe unless u use new bolts that's cut to the right length. &nbsp;also, you won't benifit much from it, your car should be able and is designed to handle the heat that it produces. &nbsp;but for example, after a long hard run, you can leave your car on for a minute or so to let the engine get enough oil and cool down from the hard run.

[rotaryknight]

hey prob saw this modification in Option Magazine or YV or Car Boy. &nbsp;Yea it does work but hey you know what you're not in Japan and that's not cool here.

so uhh... bodykits and other non-functional mods are rice... &nbsp;i get it now. &nbsp;time to make fun of all the s13 silvia conversions and such....

damn there's a lot of rice on this board.


anyways, if you want to raise the rear of the hood you should just get new longer bolts of the same thread and diameter so make sure your hood is securely bolted down. &nbsp;you're probably already aware that a bunch of people will make fun of you... so if you're still gonna do it you might as well do it right.

your windsheild washer nozzles will also be pointed slightly higher too <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt=':p'>

now that u mentioned... i do feel kinda bad for getting a s13 silvia front w/ a KA... maybe i should start a poll, yest i will!

[twofortysx]

I agree that if you are having over heating problems that you likely have a problem. &nbsp;I take my car on hard runs all the time (90 miles @ 80+) and have no overheating issues. &nbsp;

You might want to get it looked at.

[SR20DET S14]

man just skip over the bad replies n just do it man. that really helps ur engine cool down. my friend on a supra NON turbo did it and it helps it a lot. i'm planning on doing it.

washers will do the job just fine.

[silviasichigo]

Look when you do this all you have to do is break the plane of the rubber seal. If you look there are two ways nissan designed the rear water catch. There is a small lip there to prevenent water coming in. Unless you have an SR-20 Or an RB-20/25/26 then you do not have to worry about water coming in. The engines mentioned above have the coil pack cotroller at the back of the engine I relocated mine.Even so they are water proof too.I have had this done from day one and you can barely tell that the hood is lifted up in the rear. This works does it work well? I don't know but I do not have a cooling problem at all and I do have an SR. You should careless wtf these people think. How many of them are you going to see on a daily basis.

Go to my Silvia then look at the front Pass pic it is the last one you can barely see the gap. (http://community.webshots.com/user/silviasichigo)

[camppain]

i didnt read everyones comments since ithey werent very informative.

but think of this raisinng your hood will cause the following problems. if im understanding how u want to do it which is on the front correct?

if so u will have this to worry about:

hood vibrating causing noise at high speeds

hood accidently popping up slamming into ur windshield at high speeds

reducing the aerodynamics of the car. (i think)

im am absolutely postive about the first 2 the last one i could be wrong.

but i wouldnt do that from the 2 simple facts i stated. your hood was not meant to be propped up like that.

again im basing theese facts on how i interpreted the way u are going to do it

[silviasichigo]

What I think he means is at the mounting brackets at the back by the windshield. The two bolts on each side. What I did is remove the bolts, Then I out two 22Guage washers on each bolt.Screwed it back down. What that did is break the seal that the weather stripping provides and lets the hot air escape right up the front of the windshield. Since I have an open Grill in the front of my car the air is sucked right in and pushed right out the back.

ohh ok i see what ur saying now <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'> thanks for clearing it up. in that case as long as it isnt done to high i dont think it would be stupid. maybe u could get a body shop to fab some fiber glass around the sides of the hood that run along the fenders to close that up to make it more stock ish so it looks like its made that way? just a thought......

i wouldnt do it but thats just me i would go with a vented hood.

[silviasichigo]

Yeah me too I just did it because it displaces alot of air until I can afford a CF or FG hood. Good Idea though.

[Anubis]

someone might have already said this, but when you wash your car in future or when it rains, all the waters gonna run into the engine. Then i dont think you'll have to worry about overheating anymore. But now its all water damage talk.

[silviasichigo]

Actually if you look closely you will see a few deterents for water in to your compartment. First is the weather stripping which is guaranteed to fail so they made a lip to flow the water towards the fenders. Finally that Black grate at the bottom of the windshield channels water awayfrom the engine bay. We are talking MM when you add the washers so it will take a massive amount of water to flood the compartment.

[adey]

Okay... uhhh I've never considered doing this to my car, and I don't plan to, but what's the big deal? I've seen it many times and never have I thought it looked "ricey" or stupid. A little out of place, sure, but FAR from rice!
Give the guy a break, it's not like he's asking for opinions on a 4 vs 5 foot long Arospeed decal on his door or anything...
yeesh.

and to the camry owner: it is your folly to believe that ANY internet commnity is free from flaming and similar derogatory comments. That Naivite will soon wear off though.

[91CRXsiR]

i just really wanted to know if it was safe , because some one mentioned that if it were to be in a front end collision the hood might come flying through the windsheild .. that wouldn't be very nice.

but wouldn't the shape of the windshield just slide the hood upwards?

[sykikchimp]

Hood should fold up in a front end collision, and wrinkle up so that it won't go through the windshield. having the rear jacked up 1-2cm isn't going to effect anything.

[JeffNJ]

In response to the post that mentions the idea of this mod being to raise the roof just slightly enough that the seal between the weather stripped and hood itself is broken, thus allowing hot air to flow out without causing any serious ill effects because there are other means of water displacement that are still in effect, I ask only this then: &nbsp;Why not leave the hood exactly where it is and remove that back piece of weather stripping "guaranteed to fail" anyway? &nbsp;Would that not just acheive the same effect?

[silviasichigo]

If you would open your hood you would notice that the weather stripping is just below that lip I was talking about. There is a hump on the hood that makes contact to the weather stripping right behind that there is the lip. Even if you remove the weather stripping their is still a sill with the lip keeping water out and air in. When you place the washers in you are not only trying to Break the gap of the weather stripping you are trying to break the sill on that lip.

[misnomer]

OK, to be productive.

The engine bay is exposed to the elements from below, shit will get wet. I wouldn't say it's not going to potentially be a detriment to introduce more areas for water to enter, but it's nothing significant.

If I remember correctly, there is a rubber weather stripping going alon the backside of the bay. Raising your hood a couple of milimeters won't necesserily clear this. Best bet would be to simply remove it. This entire paragraph could be false, go check out your car to be certain.

If you're just going up a couple millimeters, there is no need to replace the bolts themselves, but be careful if you're going higher. This will also change the contact point on the clamp at the front, it will wear different and could potentially cause you problems.

All in all, as somebody else said, unless you've made some modifications that require additional ventilation, your car shouldn't be overheating. I'd check out your cooling systems as soon as possible. If something is wrong, sure lifting the hood a bit will let it stay a bit cooler, but I'm not a fan of bandaids. If there's a problem, fix it. Don't do something to make it less significant.

As far as all this rice debate goes over raising the rear of your hood a couple of millimeters. . . pull your heads out of your asses.

[nrcooled]

I have been looking for a way to get my engine bay cooler once it heats up I do notice a slight drop in hp. &nbsp; I may give it a try to keep the bay cool but only when I take it to the track
