I use the cyclonic, just looking at it after a bit of driving I can see how much dirt has not gone into the air filter. A top spin would probably work even better but too expensive for me.

I'm a fan of the cyclone head. You can see it filling up with bugs and crap as you go, and its easy to remove, tip out and put back.
@LockyourHubs4WDing 3 жыл бұрын
That's probably why they're so popular on earth moving machinery etc. I also can't see the cyclonic seperaters providing too much addtional air flow restriction as they fill up, unlike an addtional filter.

I've had my Patrol Cab Chassis for 18 months, and been using a Cyclonic Pre-filter Head for the past 12 months. I find my Filter is much cleaner, and need to empty the cyclonic head about once a month of fine dirt/dust particles driving around Sydney. When raining, if heavy I would need to watch the cyclonic head and empty captured water on a daily bases, if light rain or drizzle for a day or two, water would collect over two or three days, but would evaporates after a day of no rain, even quicker in summer. A Cyclonic Pre-filter Head is a no brainer for me

Are you going to do more parts to this video? I’m so interested to see them tested even more! As you said, dust and water ingress would be great to see tested! I don’t think anyone had ever done a proper in depth video on this? I could be wrong! I love my Donaldson but personally I don’t see it pick up water but I never get big rain down south Australia. Other than that it’s perfect for bugs and sand in my personal experience! Love the videos keep them coming!

Awesome mate. The Donaldson sure did better than I expected. In saying that, as they do seperate up to 75% of dust before it enters the engine air filter, I think it would be a great addition to the 4x4.

I couldn't believe how well the Donaldson worked either! I had to double check the footage when I was compliling the results, I though it must have been wrong. We'll check how well it works for dust and water in upcoming videos, but I'm impressed so far!

Super great awsome stuff. A part from the sock I would have stated those results with the forward ram head being the winner. I have had the debate with way too many people with rear facing very expensive SS snorkels trying to explane that a rear facing head is a bad idea due to the negative (sucking) pressure that it causes. Thank you for demonstrating that. Do you know where the idea first came from? Well I understand it came from off road and mud racing and it was not for a performance issue. It was to stop lumps of dirt and or mud from going down the snorkel and into the air filter that was thrown up by the car in front. 🤗
@LockyourHubs4WDing 3 жыл бұрын
I think now unless you're driving a mud bogging comp 4x4 you would be silly to go with a backward facing SS snorkel. Though unfortunately they still seem to be selling plenty.

We'll see how they fair in comparison with the competition with dust and water. Interestingly, I drove in moderate rain today with a forward facing ram head, for about an hour and a half. Checked the (sealed) airbox, there was about 30 or 40ml of water in the bottom. Not nearly enough to cause an issue, but it makes me think in torrential rain for a big drive, could be a different story.

The cyclonic admittedly look different, though the flow shouldn't drop off as they fill up with dust unlike other options. You'll probably end up laughing as they're replacing their dusted motors and your cyclonic seperator has done all the heavy lifting for you!
@smashedhulk8492 4 жыл бұрын
I think the distance of a rearward facing snorkel to the body would change this due to the potential for higher pressure. While the Safari snorkel has a similar standoff to the body compared to the pipe, I think the design of the Safari Snorkel is improving inH20 vs. the pipe. How much, I don't know.
@LockyourHubs4WDing 4 жыл бұрын
The intersection between the wind screen and the roof is a low pressure area at speed. I'm not sure if our "backward stainless emulation!" is far enough away from it to to negate the effect. But going by the forward vs backward ram head figures "less than 4 inH2O" I would say not a lot. I think the main issue with the backward facing snorkels air flow is the plain cut off end, right after a bend.
@spencerm106 4 жыл бұрын
I believe what you are seeing is Bernoulli's principle, it's creating a low pressure after passing over the 90 degree chamfer and making it harder for the engine to breath. I keep trying to explain to the yuppies that insist on the those snorkels, generally find them in patrols with 6" lifts and 35" wheels. The end needs to be cut at an angle. That's why the ram head works fine backwards as it's angled. Snorkels are designed to act as a ram head and face forward. My preference is for the Donaldson's as a pre filter because the sock covers need more maintenance and shouldn't be left on all the time, only when needed.

Thank-you very informative 👍 Just installed 3 inch mandrel bent exhaust to 1 HZ with safari turbo/front inter-cooler. and have just ordered the new release Safari Armax snorkel for 100 series. based on your findings and manufacturers claims, should be lot more power with air flow in and out ! and with tune to readjust AFR safely even more benefit ?
@LockyourHubs4WDing 3 жыл бұрын
I had no idea Safari were releasing as Armax for 100! I must check if they do one for the 80. The 1HZ was never really designed for a turbocharger with the pre-combination chambers in the head. Though if you only use moderate boost and keep check on the egt temps, with a decent tune, it should be fine. It's just a shame the 105 didn't come with the 1hd-fte!

To test the differences between the two inlet styles, the reverse facing stainless style and the ram head, you either need to test as I did or a stainless body with the ram head and then backward facing head. That way the only variable is the inlet and let's you work out which one works better.

I’m putting a snorkel on my Tacoma in the next month or so. Your video got me to decide to put on a cyclonic pre filter. What brand would you recommend? And what diameter tubing should my snorkel have. I have a 2.7l 4cyl Tacoma. Not a huge engine by any means. I was planning on doing a hilux 167 snorkel but noticed the diameter of the snorkel is a lot less than the ARB and the Dobinsons snorkels that are available for my truck. Is this something I should worry about?

The prefilter is a Donaldson. If the snorkel you're looking at is designed for a smaller engined vehicle, it my well hurt performance with airflow restriction. It's especially a consideration if you might be modifing the Tacoma further down the track.

@@robkay9227 I did look at that after watching a video by, let's just call them "Bury my Diesel" :) Stating that the smaller cyclone head was the best for separation. The Zook has a 3.2L v6 petrol with a redline at 6,500rpm (And being a petrol, especially when driving sand dunes, I sometimes have to do a spot of limiter bashing...). So with a VE of around 90%, that equals around 300cfm. This cyclonic head is rated to 320cfm by Donalson, and the smaller size, is only rated to 170cfm, so that would definitely strangle the flow. Later on, I look into the smaller vs larger cyclonic heads.
