WK2 Snorkel

[Hutch]

I am with Wanderer, been in a convoy when we drowned a vehicle, never want that to be mine. One thing I can say when u stomp on it their is plenty of induction going on, you can certainly hear it....
Seen a marginal increase in fuel but I think is my driving, have a 600 km trip on Friday so it will interesting to see the mileage from that.

If someone has a Dyno I am happy to supply the car...

This can't be replicated on a dyno.

Hi Craig..Too true..but comparing Dyno with OE vs whatever snorkel would give and indication of how the donk is breathing regardles of air ram effect which supposed to be one advantage of a snorkel...I'm interested in the results that's all..I do know someone who didn't like the Airflow snorkel head on an early model Jeep and replaced it with a more cosmetic one (Safari I think) and almost straight away replaced it with the Airflow one because of negative resuls..So snorkels while spelt the same ain't necessarily so...Remember the Castrol GTX commercial way back "Oils ain't oils Sul" well coming from a engeering background I like objective data which can only be had via instrumentation and correct procedures...Subjective does ease the mind though so like I've said "If you're happy then that's what counts"..Me?? It's the numbers.

Hutch..Any diesel workshop that does preformance tuning ie remapping or chipping would or should have one

Also I think on this thread someone did or used to do performanvce tuning an found that by altering the air intake plumbing length & bends, the vehicle lost 65kw..Too lazy to look back but I think that's the gist.

Actually, Craig dyno can be tested in real world simulation. When my Commander was the Airflow mule it was dynod in a wind tunnel in front of a giant fan spinning at different rates. Michael and his guru had worked out fan volumes to imitate real life.

I can't remember the figures anymore and seemed to have lost the (secret at the time) test results but it was about 8% more power and 10% more torque, the same as what the chip gave me. I took chip out and gained 10% improvement in fuel economy once snorkel was on.

Wanderer - haven't had one fitted yet, there wasn't wasn't any ready when we did the Cape and Kimberley last year so I'm conserving cash flow until 2016 when next big trip is planned. Until someone proves science behind the other brands though the Airflow is the only one I'll trust.

Hey mate, in my experience it would have to be an inlet restrictor to lose that kind of power. Single digit percentages either way is what you are looking at, even doing it wrong on purpose.

Also on numbers, by how much does the install of a snorkel increase your cars wading depth?

It's not just the wading depth. Many a diesel has been fine in puddles that resulted in a deathly bow wave by water coming up at front and over bonnet. Got caught in a river on the Cape last year, had to take more of a run to get out it than I'd realised on the way in. All was good, bow wave must've made an air pocket but it was a scary few seconds caused by a depth marker not at the deepest section .

Power loss...I'd have to wade back through this thread to find the post stating that..Not my figures but you have a point.

Wading depth??..Well not enough to do turn it into a submarine like you see on Youtube..not really what a snorkel is for on these vehicles..I'd say stay with what Jeep say to be safe..The engine may be safe from gulping water (the advantage of having a snorkel) but the electroincs are often not especially if water gets into the cabin..The big advantage is if you hit a puddle too fast and the water goes up over the bonnet or in a water crossing a bow wave or a return wave from the approaching bank comes back at you (saw this happen on the old Jardine River crossing Cape York & stuffed the diesel..a tow away) or a hole you don't know about and the nose dips...I'm not sure how long these vehicle can stay static in water above the recommended wading depth but past experience is if you do stop then in about 2 minutes you're in trouble (saw this on the Gunshot - Patrol mind you and all bar fish flowed out)...None of these SUVs are water tight...I tape up drain holes in the doors if a crossing is siuspect (after walking it) and have had water up to near the top of the wheel arch on my Commander but I didn't stop....I had a South African friend (happened in South Africa) stall and his started to filled with water almost straight away..Stuffed everthing, diagnostics lights and all alarms on and big bucks to fix..So short answer is I don't know and am not about to find out on purpose..So play it safe & the snorkel serves as an insurance policy and besides most of my driving is desert where the snorkel again comes into it's own..cooler air up off the sand and the bulldust is less.

Also don't take me wrong I'm not bagging Stu's snorkel but I do know the development that Michael puts into his Airflow snorkels..& yes I have a photo of my Commander on the Balfour Track with water above the wheels & I had an Airflow snorkel to save the day and my undies
