Glad to see you've got a MANTEC on the way (you first posted on this topic in Sept 2013). Muppet is 1/2 right and 1/2 wrong - YES the rearward facing head doesn't affect engine breathing (was discussed earlier in this thread) - and NO it's not the Mantec that's unsuitable suitable for Australian conditions, it's the tiny D2 airbox and filter!! i get size envy everytime i see a BMW E36 318i or new VW Beetle airbox.Quote:

To me that suggests that the Mantec ID is too small, but that's just my opinion :) And obviously the UK is a lot wetter than here!
thanksfor the clarification muppet .... good for Australian conditions eh! :p
All jokes aside though, if the snorkle head is installed correctly water is not injested into the snorkle pipe and the water in the snorkle head will drain away.

Muppet.... Interested in how the ID of the Mantec makes a difference to the effect of rain.
If the snorkel isn't physically big enough it's going to restrict the flow to the engine, which means it's going to be 'sucking' a lot harder to get the air in, and thus is more likely to draw rain in.
There was some discussion about if it was sucking the water out of the guttering or off roof racks but I didn't follow the discussion to its close.

In my opinion Mantecs are too small (being 2.5" thin wall pipe) for anything other than a stock td5.
So I made my own... 3" and follows the line of a mantec, but with a pre-cleaner on top.
Flows nice, looks nice, is nice... and I can say I made it :)
Do you have pictures of your snorkel?
I have the same thoughts about the diameter and thinking about building my own.
Just in case you missed it I repeat - if the snorkle head is installed correctly water is not injested into the snorkle pipe and any water in the snorkle head will drain away - just as it does with the safari snorkle.Quote:

Here's a somewhat crappy photo (cropped from a full photo of the car), I will take more when I do a build thread.Quote:

You have not considered the effect of pipe length in your hypothesis.Quote:
