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

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. 🤗

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.
@LockyourHubs4WDing4 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.
@spencerm1064 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.

@@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.
