There was a test done years ago by one of the land rover mag that said some knocked 6hp off

^^Believe Pete Bell came to similar conclusion on the dyno. You never actually own a Defender. You merely look after it for the next generation.

forget the ram air principle with a raised air-intake.
You get due to the bends whirlwinds and due to that lost all benefit of the "ram air", on the contrary even. Only way to get best performance for an air intake is a tube as short, wide and straight possible. 28/02 - Loss of a good friend...

My insurance company (Adrian Flux) actually class it as an 'off road' modification, and subsequently charge more! Grrrrr Euro-Leafing to infinity and beyond..... |

What??
How can you define a modification on an off-roader, off-road?  28/02 - Loss of a good friend...

It won't be Adrian Flux but the underwriter of your policy, the company Adrian Flux has used.

^ Can't find it anymore, but some time ago I did some calculations to find out if there is ny difference in wether the safari snorkel head is pointed forward or to the rear, and found that the vehicle velocity is neglectible compared to the linear air velocity in the snorkel, thus the ram air effect of the forward pointing snorkel head is as good as nil.

I'm looking at fitting a snorkel to my 300tdi and found this thread. Some interesting posts here about ram air effect, also very interesting about Adrian Flux charging more for it as that is who I am with
To change the subject slightly I've found the below snorkels on fleabay and wonder why there is such a massive price difference and if I am missing something. Surely a snorkel is a snorkel, and a snorkal is just a long, filterless tube that collects air higher than the intake can. So what makes some worth 2 or even 3x as expensive as the first one below despite looking (pretty much) the same and doing the same job (presumably)? The only obvious difference (at least visually) is the geometry at the intake level. Does anyone know of any other reason (besides branding etc) that they are more expensive?

Well, it depends.
Do you want your snorkel made out of takeaway box plastic or proper plastic? The last one is a Mantec one who are always going to be the most expensive manufacturer because hey just seem to be, but arguably they are the best quality. http://www.mantec.co.uk/ The first two look like safari snorkel copies. A Proper "safari" snorkel is made by Safari in Australia and designed to put up with being used in Australia so use proper plastics. http://www.safarisnorkel.com/docs/product.htm It may not make much of a difference as you say ultimately it is just a fancy tube, but when your up to the point your snorkel is now needed do you want to be thinking about weather the plastic has cracked on the back where you cant see it due to poor design or someone banging it in a car park or would you rather know that it is safe and well designed to go up to the windscreen in water?

Does everyone remember hiclones - people used to spend time saying it made no difference and if it did, manufacturers would fit them...until they started fitting them.
Personally in the real world, i think the net is 0 or +0.1 in favour of the RAI, but it isnt going to make you faster or more fuel efficient, just counter some of the negatives from having something else in the air flow. In settings with dust or water, then it will give you a positive effect, but negligible. For me its always safari - i will be on my 5th - Remember, they are designed to be a sealed system, mantec isnt plastic one isnt...unless somethings changed These cheap copies just arent worth the effort to fit them Mike |
