Good read regardless of which side of the fence you are on. Pretty Land Cruiser specific but good info I think.

TeriAnn those bonnet bulges, when on a diesel, are for the intercooler and not just for looks. Just for your info.
(well mine is)

An intercooler mounted at the centre top of the bonnet sitting over the middle of the engine??

Where I come from a top centre mounted hood scoop is usually sitting directly over a pair of double pumper holleys. Or at least a double row of IDF Webers. Laguna Seca raceway is nearby and and during the week of the Monterey Historics and Pebble Beach concourse some very amazing cars become a very common sight.

Sorry I just think it is sad when a factory adds a pretend hood scoop to make a vehicle more "sporty". It's kind of like a decal that says "4X4 off road" makes a vehicle more of an off road vehicle.

You would think that Toyota would have mounted the air intake of their 4X4s higher than they evidently did. Or at least had a factory snorkel option. Heck, even my car had an available factory optional snorkel when it was new.

An if there's a count, I'm pro snorkel.

Actually yes!






but I digress. off topic from me finished

I can't believe this thread is still going! Wil's attempt of explaining to me the benefits of a snorkel where I see it as useless is what started this whole thread (Thanks Mark!).

As for an update, I agreed to the Taco snorkel and I must admit... it looks really freaking cool!!!

So it's official... the ladies really do dig it.

If it "looks cool" then it's not really useless is it? After all, it's useful....
























for looking cool!

Hello,

A snorkel is very useful...

Look what did a friend of mine with his 4Runner:

that's pretty deep. Looks like he almost got boned. Wish we had more diesels here in the states in small/mid size.

This makes no sense to me first you said you haven't been in a bow-wave situation with a truck but you have on your enduro and then you tell about how you plunged with no opportunity for a bow-wave...

Poorly written, maybe...

What I meant was, I've never been in REALLY deep water with the truck, only somewhere around 24". I have been in really deep water with the bike. During that Hare Scramble, I had to go through that hole 4 times. I also had to go through a flooded trail that was somewhere between 24-36" deep and a few hundred feet long. There was a bow-wave there, but I'm not sure if it helps the bike since the intake is more than half-way back. The front fender was under water, not sure where that put the water level on the intake.

My main point of the whole thing was to say that my bike ran regardless of the spark plug/wire/boot being under water. And that sometimes crap happens, and you find yourself in deeper water than you expected, and a snorkel is the ONLY thing that will save you from instant catastrophic engine damage. Period.

Yes, this is what Subaru does with all their turbocharged engines as well. The hood mounted IC works fine as long as you're moving. When you're stopped, it acts as a chimney and becomes an interheater. So, it has it's disadvantages. However, the setup is also cheaper, easier to design, lighter, less turbo lag, and less pressure drop than a front mounted intecooler. It's also less prone to damage.

The Subaru rally cars usually convert to front mounted coolers for higher horsepower.

I'm going to end this war right now with this link. :safari-rig: The debate is over. Abandon ship, and god speed to you all.

This will be one for the record books. (mommy, where's my woobie?):REExeSwimmingHL:

I can now say that I HAVE been in VERY deep water with the truck. Water that would have in fact drowned my bike for sure. I measured 36" high water mark on the truck, and that is after the bouyancy effect on the truck body. I expect water depth was more like 38-40".

A few things became apparent:

1) As I suspected, a modern electronic gasoline vehicle in good repair and with zero electrical preparation, can in fact ford water this deep without any problems.

2) The factory intake system in the Disco is capable of handling water depth which is as high or higher than I ever intended to attempt.

3) I still want a snorkel anyway. It would make these events much more safe and fun.

4) And it was only luck, not driving skill or engineering that prevented engine destruction. One wrong move, or undetected hole would have meant certain drowning.

5) There was some evidence of water entering the airbox. It appears it actually got in via some pathway through the sides of the box, not through the intake. I'm guessing the fan slung it onto the box and it got through the seals due to inertia. A snorkel won't prevent this, so something else has to be done in addition to the snorkel.

Fans throw water everywhere. If your intake is anywhere under the hood, fan splash can probably reach it. Most air boxes are adequately sealed against air infiltration, and if air can't get in, neither can water which is more dense. To check for air infiltration in the air box, open it up and look for dust tracers around the seals.

After browsing through this thread, thought I would post up a link for my homemade Snorkel Conversion I did for my Tahoe. Complete writeup is here. Anyone want me to post the same writeup on this site complete with pics will be happy to do so.

Have not had the chance to test it in high water yet, and it does NOT seem to work as a chick magnet like the earlier cartoon.

But it sure is cool! One of my favorite mods, an instant conversation starter.

You bet! Please post it up in the Domestic section. It would make a great addition to ExPo, plus only registered users can see attachments on that other site.
