hey,

I recently put on a predator hood from aerogear that has several open vents to the engine bay, and I also have a short open Air intake, is the water than can get during rain or whenever enough to hurt my engine seriously while it is running???

I still have my stock box, but I LOVE hearing my engine breath specially at high RPMs, let me know what you think.........

Thanks.

 

if u got snow, then it might melt in.
i was always wondering about intake scoops and hood scoops and fender scoops...how water doesnt get into the intake.

does anyone kno if the bypass valve for the cai is flawless?

 

The valve will only work if the entire filter is submerged!! Be cautious when going through deep puddles....go slow!!

 

i dotn get it.if the whole filter is under water then the bypass valve works?
what if its not totally submerged?

 

The valve uses suction to activate. For example think of a vacuum attached to a bowling ball. The vacuum will attempt to lift the ball (intake under water sucking water). However if there is a hole in the vacuum hose the ball will not bee lifted (filter under water but bypass valve installed). The valve will allow another path for the intake to draw air. Now if you just hover the tip of the vacuum over the ball it will still try to suck it up but will not lift it (simulating the filter wet but not completely submergerd and the bypass valve will still be closed).

Hope this helps...

 

To really have a problem with getting water in the engine with a full CAI, you basically have to get the whole filter underwater. If you're stupid enough to be driving through that kind of water, you deserve to lose your engine anyway.

With a short intake and vents on the hood you will not be at risk of ingesting water. Think of the Ram Air hood on a Trans Am for instance, that thing's like a freakin water scoop, but how many times do you hear of a Trans Am blowing a motor from water?

 

thanks for the clear up..

 

not yet but this is where i got it from if it might help:

The vent going down on the passenger side at the middle of hood is the one directly above my air intake.

 

That should not be an issue for you!! Unless you do some deep river crossings!!

 

DragonCTR69: "Actually a Short Ram hurts your performance more than it helps... (in most situations) "

How do you figure? Anything is an improvement over the stock air box and filter, unless you are talking about standing still on a hot day, in which case stock you might be better off, but other than that the air is cooled off enough to help performance some. Every 11 degrees you cool the air that goes into the engine you gain 1 percent whp (approx), so lets say the difference between the stock air box and the short intake is 60 degrees, thats only about 6whp. When you add the pressure that the ram intake gives you (assuming you are using a good filter) this equates to much better performance with the ram upgrade (unless you are using a huge apex dunk with a cat back systems, hence signifigantly decresing backpressure giving you a drop in performance).

 

what the hell u taking about?

 

what do u suggest for the short ram on the JRSC setup? they recommend the short ram

 

i dont think there s any problem getting enough air into the engine bay..its venting the hot air out that would be my main objective with hood vents..ive been considering having a custom vent setup done to the hood that would vent away from the front of the car towards the windshield..would that work?

 

Thanks for the info, but I bought the hood cus It looked cool, but my only real issue I was worried about was gettin water in the filter. Not really the hp or performance of it.

 

*cool, no need to spend more money*

 

So I should probably take the Short Ram off, put on the stock air intake and housing box, but remove the resonator and intake duct??? That Seems to me like the safest and best solution................

 

I have driven in a crapload of rain and unless you drive through a massive puddle that can submurge your intake then you shouldn't have anything to worry about.

 

Hmmm...normally I'm not one for vents and such on hoods and fenders, but if the vents can really be set up to be functional I might want to get one of those. I'm going to be running a B series with a rather large turbo so I will need all the engine bay cooling I can get.

Perhaps I could use some type of materiel under the hood to route the air from the front intakes through the intercooler and radiator then up and out the vents. samdawgsol, what was the hood made of? Metal...fiberglass...carbon fiber? I'd prefer vents that were more rounded off but I may be able to work the vents on that hood to be rounded.

 

Its made of fiberglass, and its an aerogear predator hood cost about 390(an extra $100 for shipping) on racinglab.com and use coupon code "PTCRUISER2002" or 2001 if that doesnt work and you get 10 % off the $390.

 

Don't Flame Dragon, the topic says "water can get into the intake". BTW: I disagree with your theory on the OE vs. aftermarket ram issue. The ram would theoretically deliver more volume as well as more volume because the "jet stream" has less to bounce off. There are (I think) 3 turns in most OE air intakes, while the ram doesn't have any. On the heat issue, if you dont cool the air that's going in there then yes, the stock one was better...but with a cold air box you'll be much better off (IMO). Check that out. Also, my rule of thumb on with aerodynamics is that the don't increase/decrease performance enough to worry about if you're driving under 130.

 

styler whats that around your intake?

 

Thats not my intake, I wipoo poo was...but it's a cold air box. It takes air from below the headlight, same place a CAI would but theres much less of a chance of waterlogging because the tube doesn't go directly to the engine. It's very efficient, and can be made from really cheap stuff (any kind of somewhat hear resistant tubing will work). It also protects the ram air intake from pulling heat (mostly from the exhaust manifold) into the cumbustion chambers (it seals with the hood). and no, it's not a baby hot tub.

 

Dragon,

Actually I kinda glanced at it but I really just read the topic. lol Whoops.

 

anyone else have a predator hood and what did you do about your intake?
