Thread: 1993 200tdi power loss after fitting safari snorkel

you havent got a kink in the flex pipe? I've seen that before

Take the snorkel head off and check down the external pipe for any foreign material down there, I have heard of packing getting stuck down there.

I have heard someone else in the UK also mentioning this years ago.I think the consensus was that the 200Tdi Defender uses a 50mm (2") inlet,and when you fit the Safari snorkel,which uses the original plastic mountings under the cover on the LHS,somehow the turbulence causes a lack of power.Hence when I fitted a snorkel to my 200Tdi,I used a stainless unit from Southdown,that does away with the original plastic inlet ducting.Also the ducting,because of its design,which just clips together,isn't really water tight,and luckily when I removed it from my vehicle,I also found that the ducting tube had rubbed through and had a hole on the under side,which I wouldn't have seen had I just fitted a Safari snorkel.

Thanks for that as it sounds logical.
I was looking at the under bonnet flex yesterday and its very small, in fact the smallest part of the system.
I have a spare wing inner moulding and will have to see if i can modify it for a larger pipe.

Personally I think they are a restriction but have never done a pressure drop test to confirm it.

On my 300Tdi Safari Snorkel I cut off the spout inside the guard (it steps down from around 75mm to 62mm OD0 and replaced the hose between the snorkel and air cleaner (which is only around 2" ID) with an 80mm ID hose.

That is one of the major differences between the 200Tdi & the 300Tdi.The diameter of the inlet is much larger on the 300Tdi,and at least with the Safari snorkel on the 300Tdi it uses its own connection for the inlet ducting,whereas the 200Tdi uses the clip in factory ducting and tube,which isn't sealed and can lead to ingesting water

Good luck with removing the factory inner moulding if you have a heater box fitted,as there is no room to manoeuvre it around.I ended up having to cut mine through the hole under the side panel,totally destroying it.But luckily I went this way,as that is how I found the hole rubbed in the convoluted ducting tube.

Are you talking of the snorkel inlet Wayne or where it goes through the guard ?

Either way, not good.
