CAI, Hydrolock, and alternatives.

Like in all my posts, actual questions are numbered and at the bottom.

Let me open this up by stating the following. I love driving through puddles in my car! During the spring, it rains a good bit, and I make sure that I find every puddle gathered in ever crevis of the road and I run through it at speed. These puddles are normal city puddles, so they are (realistcally) at most 6 inches deep. Of course when you plow through them they create a lovely spray up the side of the car.

This fascination with puddles (probably developed when I was a small child, and increased with my work in rally racing) means I can't get a CAI, or does it? I figured the stories of hydrolock have been blown out of proportion, but I also figure that my bad puddle habit means I am only increasing my chances of doing such to my engine. I thought, that with the snorkel gear already in place, the option for the Volant air intake (or similar style) would be available for the SVT, but I appear to be wrong. The only thing in similar style I can find are the K&N and the Focus Sport short rams that have heat sheilds and do a "semi - enclosure" style of seperation.

My questions are:
1.) Knowing I can't break my habit, is the short ram my only option?
2.) Are there any Volant Air equivalents for the SVT that utilize the built in snorkel system
3.) Is there anyway a standard CAI and I can live in happiness without the fear of the evil Mr. Hydrolock?

Sorry for the long post, haven't posted in a bit, and wanted to be as thorough as possible.

I've been pondering the same such type questions - I'm at work but on my home computer I have a link to a good volant-ish alternative for the SVTF.

from all the reading I have done here, I would say that the overall opinion is that with any CAI, hydrolock is a risk, albeit a slim one. Add your fascination with puddles into the mix and a slim risk might shift to small risk.

So, you might have a very small risk of actually ingesting enough water to cause damage, but it's still a risk and, like I always say, "Freakier things have happened".

A CAI has not been shown to have more than a 1-2hp gain (if that) over a short-ram intake. With a short-ram you eliminate the risk of hydrolock.

To me, a risk (no matter how small) of destroying my beautiful engine is not one I'm willing to take.

But it's all up to you....

What I really want to know is if there's a way to modify the volant intake for the standard focus for the SVTF

If your considering a CAI then I would invest in a shield. Wether you buy one or make one doesn't matter but I would get one none-the-less. Also, be prepared to clean the filter often because as you know that water has a lot of dirt in it and will dirty the filter fairly quickly. I clean mine about every 6 weeks. Other than that, a short ram would eliminate the risk all together. Hope this helps.

idk why anyone would bother wasting the money on the short ram, unless you have a functioning hood scoop as soon as the engine heats up you lose power rather than gain.

summer months would be a bear. man volant needs to make a kit for the SVTF soon =/

Yeah, that is the other side of the issue. I live in GA, so summers are oft in the 3 digit zone. this makes it difficult to say "yay" to a short ram, but I haven't seen many hood with a functional air scoop over the air intake area of a short ram.

Also, if you did have a functional scoop over the short ram, wouldn't a downpour cause the same amount of issues as my puddle splashing craziness?

I don't think it would be nearly as big of an issue on the short ram w. scoop. Especially since you would have to put some sort of screen over the scoop to prevent debris from coming through. Water intake would be minimal, whereas the CAI is so close to the ground that it would be completely submerged in some of the standing water on roads where I'm at in Michigan.
