I was only worried about the original Safari ram jet snorkel head and NOT the pre cleaner getting snow in it, because that is what it is there for. But that Sy-klone unit looks pretty kick ass!

They're reasonably priced as well, I paid under $100 for the model I have this past summer, zero maintenance so far. Never had it pop off in the bush. I didn't buy the mounting kit, I used a heavy rubber tube with a couple of hose clamps, works great, looks proportional with the vehicle as well.

did the size come close to the factory snorkel or the safari one?
I have a Safari Snorkel, the 9000R pre-cleaner that I'm using has 3" diameter mounting hole so it was too big to go in where the safari intake was removed.
What I'm calling a rubber tube is actually a deflection joint we had left over from a bridge job with a 3" ID, which is a little bigger than the snorkel, so I wrapped 3m rubber splicing tape where I wanted the rubber tube to stop to seal the gap, hose clamped it there stuck the Sy klone unit in the top and clamped it there as well. It's not beautiful but it works and you don't really notice the size difference. The black tape you see is covering the bottom hose clamp, kind of stuck out like a sore thumb without it.

This is off the topic but related; I drove back from California yesterday thru much rain/snow and the smaller Donaldson pre cleaner I put on recently, filled with water 2 times. Got so I would empty the plastic (fish) bowl when I unlocked/locked my hubs... Never happened using the larger sized pre cleaner-seems the force of suction pulls the falling rain drops into the pre cleaner and it builds up fast in heavy rain.
Strange looks from pedestrians when they saw they water in it too.

Yep, I really don't really care that much I guess.
I have a sump on my snorkel(s) to catch any water that get into the head. With the deep water and severe splashing we get sometimes I figured it was worth doing as a test if nothing else.
I have not captured much water in the sump even when doing days of multiple crossing or for that matter even when purposely creating as much splash as I can (playing). However when the rig was on the trailer being towed through rainstorms I did catch a surprising amount in the sump.
This was with a forward facing snorkel head with no water diverting baffling. With a forward facing head that did have a diversion baffle, I ran the highway through all day rainstorms with no water collecting in the sump at all. This setup also had no water in the sump after days on the trail and dozens of water crossing (but not a lot of sever splashing) during the Trek

Did you have them size the pre-cleaner? I found a calculator on line, and it says the 13BT will need 636 CFM, using standard values. Could probably bump that down to a 2 in the volumetric efficiency section, but that still says 424CFM. Air flow (CFM)

greg,
have you ever checked the factory or safari set up for flow?

If you run a 1HDT or 1HZ with with turbo then the safari snorkel will not allow enough airflow. I know they are building a bigger snorkel for the 1HDT and the 1HZ turbo - but for over 12PSI it still wont flow enough air for the engine = right from teh mouths of safari to me.
Merry xmas!

Louie,
Right now I´m running a afari head on a 3"SS tube snorkel. That will not allow enough airflow for my HZ once the turbo is up and running?

I can't say for sure because I really don't know what that would flow, but I doubt it would, and I doubt that your airbox and airbox to turbo routing is sufficient as well. Don't egt me wrong it will work but will be restrictive especially if you run over 12 pounds.
Whe I told safari that I was running 15 pounds they said they won't have anything that will flow enough air for that. So I am making a 4 inch aluminum with custom airbox and large diameter Unifilter for max airflow - I also feel I'll be able to seal it better than the factory set up.
The new safari 1HDT snorkel will suffice up to 12 pounds iirc.

I would put my bet in the air box .. and maybe a nice upgrade would be the 100 series air box .. that's much bigger ..

Great info., thanks for posting this. I know it helped me to get the correct size pre cleaner on my BJ74.

Glenn-BJ74, thank you for your work with the calculations on this

so, now i have issue with the calculations and real life application.
if the flow needs a 4" pipe then how do you allow for the 3" pipe from the airbox to the turbo? the turbo inlet is 2 1/2" how do you increase this to allow for the needed airflow?
in reality, the greatest restriction will be at the turbo inlet on most Toyota diesel applications. next is the tube from the air box to the turbo.

Crushers, pose the question to them and see what they come back with.
