Water Lock And Cold Air Intakes

[V35 Matt]

i have the nismo R tune intake, which puts the pod right at the bottom where the cold air can get into it.

my worry is water lock. now i wont be driving through rivers, but puddles come up on the road and i cant do anything but drive through them. So whats the go with water lock. if 10ml of water gets in is the engine toast? or will the filter block out a fair bit and as long as i dont drive through massive deep puddles i should be ok. for reference, the pod is just above where the black grill/guards are on the front.

is it worth the risk? am i over reacting? do alot of cars have their intakes low and they have no worries?

Also, the R tune has a water lock bypass thingy, but as far as i can tell, it works if the pod is submersed and doesnt suck, it kind of opens up a to let air in and the water is therefore not sucked into the engine under extreme pressure.

What are your thoughts???

Go through a puddle then pull over and look to see if there is any splash around the pod.

If none then stress less

If there is water all around the pod freak out

And then make a splash guard.

i think if youre driving through deep water with enough RPM to suck water into the engine, then you dont deserve to own a car.

or you should buy a 4x4 like mine

then it doesn't matter what happens

lol do you go snorkling much??

i was thinking about this, seen it done on heaps of high performance cars, but i dont want to risk it,.. its alot safer to make a snorkle.

if you have the R tune, then it should have come with a water bypass valve. if you drive through puddles that go past the bypass valve then its a clear indication that you are in a river and its time to climb out the window.

otherwise, get the bypass valve and stop stressing.

[V35 Matt]

i have the bypass. i didnt put it on as it didnt make sence

What i dont understand is how it works

if the pod gets water on it will it suck through the pod?

or splashes dont worry it, and it fully submerged it'll get air through the bypass?

if the foam sucked the water out of the air i would understand but doesnt seem to work like that

Can anyone inform me?

[zei20l]

it will open if it cant suck enough (any?) air through the pod

but for that to happen, you probably just crashed anyway and youre in someones backyard in their pool. but the rivers are nice this time of year

[fcruz3r]

it goes on the theory that it requires a certain amount of suction power (think it's measured in cuft/in) to draw water from the filter. If the foam or bypass valve has a lower restriction rate, then if the pod gets submerged...it will suck air from the bypass.

Think of it was a straw with a small hole cut out closer to the mouth piece. If you suck hard on the straw...u will be drawing in air from the inlet. but if you submerge the inlet in a glass of water...then u find that you wont be sucking in any water as air is drawn from the hole

put simply, air follows the path of least restriction

or be an idiot like this guy>>!! i mean WTF>>> http://www.youtube.com/watch?v=nDrlWy6IAdM

but im sure you wont do anything like that.

[V35 Matt]

So we all agree that unless the pod goes under water, it should be safe enough to use the intake without the real risk of waterlock??

I wont drive into any deep water!!!

But alas i do want more music gear hahaha, so someone can buy the intake! please lol

[fcruz3r]

use the bypass valve as a safety measure since you already have it. But since we're nearing summer...its not an immediate problem

pics of the actual CAI will give potential buyers more confidence in the product that they will receive. Links to resellers ads arn't really that helpful....my 2 cents worth

What is wrong with that?

Where are the air intakes on the mid engine NSX? Certainly not in the bow wave he is creating.... so I guess the only issue may be water getting into the cabin if the seals are stuffed or water getting in the exhaust if he wasn't going quick enough.

Having said that, if I did have an NSX, I certainly would not be doing that.
