Benifit of snorkle ram

Oh!

It was also too high, wasn't aerodynamic and it was still ugly!

At least the safari head forces air into the diesel motor.

And did I say it was ugly?

I doubt that the ram effect warrants it. With every angle in the inlet tract you lose a significant amount of pressure. (I did the numbers for a workshop dust extraction system). Then the rate of induction is going to be pretty high regardless.

The main motivation was because it was Ugly!

Anything else is a bonus

Beauty in the eye of the beholder!

The ram heads on some later model 200(?) series, now they are ugly! :-)

One model Land Cruiser (I think 80 series) had what looked like a football on top of the snorkel pipe.
It was there to cover up/disguise the top hat/centrifugal dust extractor hidden inside.
Now that WAS ugly!

What he says sounds good too!

A forward facing opening - moving forwards. Has to go somewhere!!!

You can't beat physics - but physical attraction can take a beating (god there ugly!)

Nope. Wishful thinking.
Think about it, or go have a look at your intake. Yep, I have a snorkel.

"With a naturally aspirated engine, a forward facing scoop can pressurize the air intake"

The amount of boost you can get for this is insignificant. Some years back I saw some research on this. It was done for racing cars. To get a significant boost the mouth of the scoop had to be equal to the cross section of the car and you would only get the significant boost over 100 km/h.

With figures like that you are not going to get much boost with the mouth size of the snorkel scoop at the speed that our 4WDs travel.

If I could I would definitely face mine rearward. Makes no sense to try to catch objects in your intake
The ram air thing is all marketing.

Air has density. It has mass. It is thin water. Ram air effect does work. Any positive pressure to alleviate engine vacuum is of some use.
However, the odd Eagle entering the intake will detract from the performance I suspect.

Face your snorkel rerwards means trying to create a vacuum on the entry!
Having a turbo will overcome that though. They can do that.

I've also read where flying mud and water from wheels spinning gets caught by the snorkel, clogs the air filter and potentially wrecks the engine. More common than you think, the article says.

Are you talking about a forward or rear facing ram head?

Either way, I can't really see mud and water being thrown from the wheels and entering the open face. Sounds a bit like a "Hollywood Bullet" to me.

Also, the Rams are designed to expel water (albeit not a bucket full). How else would you use them in the rain?

Would love to read that article.

Michael that's a bit extreme it may apply to mud racers but they usually position it out of harm's way but you do get a lot of wally's who can't help but smash their way through mud or water without thinking first or sitting in a bog with a rooster tail of crud shooting over their roof so some do deserve the repercussion of their actions. The average person who has some common sense won't have any problems.

ram tubes are an entirely different thing to a scoop head on a snorkle.

Ram tubes are about tuned intake length ........ they are known a proven to work, the math and the principles are well documented ..... as are the reasons they don't work when not done correctly.

cheers

If you are looking for another reason to change from std snorkel then your snorkel is probably in two parts and the join is poorly sealed and too low for those doing deep water crossings. Is it worth the $500 to change??

I just changed the ugly hat it was wearing! Definately not a $500 changeover

The snorkel body remains as original. Mine isnt in two parts, it is a single main body, a good sealing with sika flex in any joins will sort out possible water leaks.
