About a year ago there was a huge discussion on this either here or on zilvia. In the end it seems like propping your hood like that might help a little when you're sitting at a traffic light. That functional "mod" is not helping you at all.
And why would you staple a $10 piece of molding to JDM bumper?

| well that makes sense, if you're gong under 10mph or stopped that it would help with cooling the engine bay, because heat rises and can escape much easier through a bigger opening like having the hood propped up in the back. But when moving the pressure is much higher on top of the car than under it and it would seem that air couldn't fight physics and go from low to high pressure. |
a cowl-induction intake system orginated during the muscle car era and was combined with an enclosed plenum from the hinge edge of the hood that included the air cleaner and increased colder/more dense air flow to the engine, thus increasing horsepower. i do not understand the venting concept, since, as ken stated above, pressure is higher above the hood than within the engine bay.

At low very low speeds and stopped it will happen. But I can do that and feel warmer air there anyway without a propped hood, because that area is heated by the engine.
I tried the hood prop at various heights and didn't see any noticeable difference in the heat the engine ran at when it reached operating temps. There was a noticeable difference when I went to a 25% coolant mix and water wetter. It changed by about 10 degrees consistently. You can't really tell if a 2 degree or so difference in temps is due to a different air temp, driving condition, or a hood prop... The temps are constantly changing by a couple degrees so I can't say that if my engine ran a couple degrees colder once or twice that it was because of the hood prop. I haven't had a noticeable difference in temps since it's been backs to stock hood height.
The only way I can see this actually working is if you made a cover/skid plate type of mod for the bottom of your engine bay to not allow air to travel out the bottom to low pressure, and force the air to build up more and more pressure and velocity from swirling that its only option is to escape out of the area between the hood and windshield. Even then, if there is a high enough pressure built up in the engine bay due to air not being allowed to move anywhere else, airflow INTO the engine bay will decrease dramatically because more air will choose to go around the radiator instead through it and end up either under or over/around the car.
This topic is giving me a headache.

You have no idea what your talking about. I have a T3-T4 on my SR. After 20 minutes of normal driving i can light matches and cigarettes off the turbo with no problem what so ever.
Guess what the turbo sits right next to? Oh just the BMC. When you shim the hood it allows heat to escape instead of building up under your hood. When I had my black primer hood if it rained there would always be a dry spot on the turbo side. That and i can see heat rising from the hood when ever I stop.
Its not meant to suck in air, Its simply to let the bay vent better under low speeds or stops.

i run an rb which are notorious for over heating, and i've yet to have any heating problems after 2 years of driving
what you need is a good radiator, good fan set up and good ducting, not some mickey mouse'd attempt at cooling.

The hood prop keeps heat within the engine bay when the car is in motion and vents heat when the car is stopped. Think about your sunroof...
When you prop it open, you feel air entering the car, right? That's exactly what's going on when you prop the rear of the hood.
Also, you all do realize that the hood prop deal came from the Honda scene right? It was done to bring in air into the ITBs of NA set ups since the trumpets would be in the rear side of the engine bay right by where the hood would be propped.

The hood prop thing is basically an AIR EXTRACTOR similar to the ones on hoods like the Ford GT, etc...I actually didn't even know that was a "ricer" invention, w/e..I did it just for cooler hood temps.
Driving around, my temp gauge DOES read a little colder now and I drive it every day.

O yeah, I forgot to mention-the fan blows a TON of air through the engine especially with the original clutch fan. Go ahead and stand near your engine at idle and rev it, it blows massive amounts of air at higher rpms. A lot of this air will blow past my turbo and out through the back of the hood now, as opposed to when it was sealed closed and the air exiting through the bottom of the car. Again, this is definitely not a "useless" ricer mod just because Honda guys started it.

explain how the lip is functional. seriously everytime i see that "lip" |
easy, it keeps the air out from under the car at high speeds and allowing the vehicle to have constant force on the road which would give you more control and grip. Without a lip or no weight up front you can "hover" over a giant air pocket under the vehicle where the steering would feel delayed and the front tires would have less grip. Even the OEM lips are basically a plastic strip that hangs off the bumper but about 300 bucks for me

I never said it was a ricer mod. I said it was used by Honda guys to get air to their individual throttle bodies. The vent actually brings air in, and since the intake manifolds on Hondas is closest to the firewall, that vent was actually effective in bring cool air into the velocity stacks when the car was in motion, which is when it was most necessary.
Again, like I said before, at a stand still, over course air is going to vent. Hot air rises and since there's a vent at the upper most part of the hood, hot air will escape from that point. But that's at rest. Once the car is in motion, it's a different story. Also look at all the cowl induction hoods that all the muscle cars run to bring air into the carbs. All work under the same principle. bring air into the motor, not vacuum air out from the engine bay.

if it is even minorly fuctional in stopping air from traveling under the car it would increase the force on the front of the car from an itial stop as now the force of gravity has a larger surface to push against. If it folds in anyway(which it clearly is doing even at a stop with its ugly ripples) then it will not maintain a constant flow of air over or under it and create turbulance. enough flexing and it could cause the front end to Lift instead. as intead of being l the flex has caused it to / and force going <- will create lift.
-hood prop
if it does vent hot air, wouldnt a flush hood w/o washer sprayers do almost the same thing. getting any water on their(special on your ebay turbo setup) is going to be a reall bad idea real quick. it still doesnt vent at a point under load(maybe under 10MPH) and in reality I can do the same thing taking my hood off at the track.
most of all if you cant keep it cool enough under the hood during daily driving conditions.... you have bigger problems than just hot air.

Ok, first of all can we keep the insults to a minimum, and give me a little more constructive criticism? Calling me a 3rd grader without a brain doesn't help me and just makes you look immature. I'm in college and I can read just fine. I agree with you guys how the lip will not be beneficial when it's bent back where it will just make matters worst..I just think it will keep air out of the bottom of the car at high speeds if it doesn't bend back with the support of an oem lip behind it or L-brackets, etc. Yeah we don't drive F1 cars on here but we still run 10 inch wide wheels and racing coilovers for DD right?

| What I don't like about the HD lip is the ripples in it. There's one at every rivet location. Even painted there would still be ripples visible. The thinner more flexible "diamond lok" would at least eliminate some of those. A smooth body shouldn't show ripples anywhere. As for the hood prop,I just know I'd get distracted and not tighten the bolts down enough and get on heck of a concussion eventually*s* |
yeah the ripples do look like crap I think I'm getting sick of it anyway. I will do the diamond loc lip cuz it looks cleaner and lower the hood like another inch.
I'm thinking about filling the tiny holes I left with a little bit of bondo and using some touch up paint I hope it works wonders..

I'd like to get the OEM jdm lip but its like 300ish but it will cover them holes up.
yeah this **** is gonna come off soon, looks more low budge than ricer/race/etc. interesting for ****s and giggles tho

i never woulda thought the cowl hood created an intake, but now i see how it works
even if the lip was held by L brackets, it wouldnt be helping you out. Sure it would pervent some air from going underneath the car, but it would just create an *** load of drag cause of how tall it is, and the flat shape
you already messed up your bumper, so you can try http://forums.nicoclub.com/zer...age=1 the diamond loc lip, which looks a LOT nicer, or you can shoot for the ebay one
if your getting the ebay one though, it might look a bit off with 16" OEM wheels
either way though, good to see your fixing it up, and good luck with whatever you do next

I thought this shineautoproject lip was the greddy replica but I think they are a little different...the shineauto lip kinda rounds off at the bottom of he main center opening on the bumper. The greddy one looks kick *** but I still like the one shineauto makes.
EDIT: this is a c-west lip replica, not the greddy.

First off, the faster air moves, the lower pressure it has.
Second, as the volume of a set amount of gas increases, the pressure decreases.
I could see the hood prop thing working to suck air out, because of the faster moving, lower pressure air moving over the back of the hood and up the windshield. For example, next time you have a soda with a straw in it, blow across the top of the straw and the liquid will rise up the straw. I could see propping the hood high enough or using a cowl-design to induce a swirl behind the propped hood, underneath the flow of air headed up the windshield, possible forcing some fresh air down to the engine and the engine vacuum doing the rest of the work. I think a wind tunnel test on this would be awesome.
The lip-kit theory is supposed to make the front of the car lower than the rear of the car aerodynamically. Since only a fixed amount of gas is entering underneath the front, as it approaches the rear of the car it has to expand to fill the greater amount of space between the road surface and the bottom of the car, thereby creating a lower pressure zone and helping the car stick to the road. If sideskirts were utilized I could see this possibly working, if the front were sturdy enough to withstand highway speed winds. A perfect example would be NASCAR racers, note the lack of a rear valence.
Everyone has their own opinion, but R&D looks cheap sometimes, if no one did anything different we'd still be walking everywhere. 
And I hate doing this, but there are several things wrong with this post:

-LIP if it is even minorly fuctional in stopping air from traveling under the car it would increase the force on the front of the car from an initial stop as now the force of gravity has a larger surface to push against. |
I think you meant to say inertia from the static air that just happens to be sitting in front of the car when you start to drive, which will be a negligible amount. That's like saying it's harder to START walking cuz you're wearing a big coat.

If it folds in anyway(which it clearly is doing even at a stop with its ugly ripples) then it will not maintain a constant flow of air over or under it and create turbulance. enough flexing and it could cause the front end to Lift instead. as intead of being l the flex has caused it to / and force going <- will create lift. |
even if it flexes 45 degrees it's still lower in front than it was previously blocking some air from entering below the car. I can see where you're coming from though, thinking it would "wedge" air under the car, but I think the path of least resistance in this case would still be around the sides of the car.

-hood prop if it does vent hot air, wouldnt a flush hood w/o washer sprayers do almost the same thing. getting any water on their(special on your ebay turbo setup) is going to be a reall bad idea real quick. it still doesnt vent at a point under load(maybe under 10MPH) and in reality I can do the same thing taking my hood off at the track. |
You are correct, the lower pressure would pull out air from the below the hood through the sprayer holes, but cmon... those holes are tiny, they wouldn't be that effective at all.
Sorry for picking on you, those things just stood out for some reason.

My point was with the vents is that...... in reality none of it is really all that effective
specially if this guy can get away with a stock hood. venting is a bit silly when it screws up the natural flow of air over the engine to begin with. Where a running engine gets hot or not..... hell you can go to the junkyard and pick up an oil cooler off a truck and achive much much better performance for at or around 20 bucks.....

O please-I agreed to SOME of the things that were mentioned like the lip being non-functional if bent back all the way but i do think the hood prop idea works. I honestly believe that driving at 60mph with a propped hood will vent a lot of hot air from the back and the sides of the hood, as the air is blasting through the front of the radiator.
dstrcto's input was EXACTLY what I was talking about earlier with the lip and hood, I agree with him 100%. I did take into consideration everyone else's opinions but we will all have our different opinions on the matter and we'll just keep it that way.
I took off that HD lip and lowered my hood to stock, it just kinda grew on me that the mods were looking like crap. But i'm picking up the Gracer lip (on the white kouki above) tommorrow so that's the end of that.

I wouldn't count of it for much though. Lip spoilers do reduce the amount of air passing below the car increasing downforce, but it is a function of velocity. To get any practical effect out of it you have to be traveling in excess of 70 mph. On the downside you are increasing the frontal cross-section of the car, increasing total drag. In other words you are decreasing your gas efficiency.
Personally if I were you I would have made mounting brackets and attached the HD lip below the bumper so I wouldn't have to drill holes in it.

Cars are all shaped different, so there's no set speed that the lip will be functional at. For most cars, gas wind resistance become a factor at 55-60mph. Also, look through the article I posted on an earlier page...A lip accounted for 25% of the gas savings in the tests they did. So it will actually help gas mileage, you're not changing the front area really, but the decreased air under the vehicle helps out much more than any minor increase in surface area. It's kind of like when you supercharge, it's a parasitic drain on the engine...but the charger produces way more power than the drain.

Aerodynamic drag increases quadratically. As an example lets assume that at 60 mph there is 25 mph there is a pressure of 25 psi. At 120 mph there is a pressure of 100 psi. Going back down to 30 mph, pressure is reduced to 6.25 psi. Even a slight reduction of speed drastically reduces the effect of aerodynamics.
They saw a 3 mpg gain from all their mods driving at 70 mph, about 0.75 mpg gain from the lip. The average speed of a daily driven car would be far less. If we were to assume that a 240SX would get the full benefit of the gain and the driver drove at 70 mph at all times, based on the 15 gallon (or so) tank on a 240SX we would see a gain of about 11.25 miles per tank, a savings of about $1.60 with a base 28 mpg and $4.00 gas.
Realistically the OP will probably see a $0.20-30 savings per tank assuming the lip works perfectly. In a few years the OP might actually break even on the HD lip.

a lip will improve handling too, I saw an episode of "Topgear" on BBC where their race beamer lost the front lip and the front wheels were skidding around the turns..I think anything that will keep the air out from under the car can be classified as a functional lip, and a HD lip that won't bend back at high speeds can do just that IMO.
BTW, the car is back to normal: I applied some bondo on the holes and dabbed some leftover paint I had from painting my bumpers and sideskirts and it looks great-no one will never be able to tell that there were holes there unless they were 6 inches away. OEM never looked so good!

| C'mon guys lets make it easy. Get a tissue and tear it into tiny 1" strips and scotch tape it at different points by the back edge of the hood. Drive up to speed and we'll see what happens to the tissue. A few stray threads would also work. |
wouldn't the threads just blow straight back and up the windshield? <Kinda like how the air would escape I would imagine..

| Well thats the point, the movement of the tissues would settle the whole issue on what the air is doing, getting sucked into the engine bay or if air is going out. Best of all anyone who disagrees one way or the other is free to try it out for themselves which will help take care of the e-thugs and benchracers.
