Snorkel for 4BD1

[OLR-067]

In the next month or so I will be looking to fit a snorkel for the zuzu. Just wondering what others have done....prices, suppliers,type etc...

I got the local exhaust place to bend mine for me and then powder coated it. Fed it straight into the Donaldson air box.

Paul,

eventually I will be doing a mock up using pvc pipe and bends. Then take it to pipe/tube bending place. I will probably just kill rust mine.

I'd be a bit sus if you want to run a standard defender designed snorkel, as they were only designed for a 2.5 litre motor. Thats why i went for twins. I got one from a wercker (200tdi safari passenger guard) and one new from england (drivers side guard safari copy). You also need all the inner guard intake pipes off a 200 and 300tdi defender (from the guard vent to the aircleaner) and bore another hole in your donnaldson where the current water drain is located. My english copy safari cost just under 290AU at my doorstep, they are available through a few people on pommy ebay. Some may twin snorkels are overkill, however i had a very noticable difference in power when i hooked them up.

defender snorkels for tdi's vary in size

a safari has 90mm throat which should be fine for an 4bd1 i would have thought.

other brands have smaller throats i believe but i havent personally measured them.

Earlier safaris were smaller, as the 200tdi 2nd hand one i got from a wrecker was only about 75mm if not smaller at parts. The newer safaris are the larger 90mm, same with the coppies, but the pipework inside the guard you need to run one isn't.
I got the small 200tdi one first, so i had no choice but to run 2.

I just got a safari that plumbed into the drivers side and fitted a 4BD1 N'A air intake reducer/rubber, this fitted straight onto the snorkle outlet and enabled the 3" donaldson hose to fit upto it without a worry.
I'm still dubious about the twin snorkle thing. Stranger things have happened though......................

[rar110]

Paul, one thing I just remembered about the steel snorkel on my previous Isuzu County was the additional engine noise echoing back up the snorkel and out right beside the driver side window.

I did similar to Larns about 4 years ago only used a cheaper non-Safari snorkel. It suspiciously like it is only good enough for the smaller Landy engines. For what I used my machine for (mostly slow bush work and gravel roads) top end power was never an issue. However I have always felt that it strangled the 4BD1 above 2500rpm, quite noteable on highways dragging a heavy trailer. I'm going to experiment with the 3" hose taken off the Donaldson inlet and see if it runs harder.

......for a V8:eek:

In theory, in theory mind you, wouldn't a turbocharged 2.5 putting out similar power to a 3.9 use a similar amount of air?

If anything I would have thought a turbocharged engine would need more. Ignore this if you have turbocharged 3.9 diesels putting out massive amounts of power.

A bit late here, but I have a Snorkel fitted to my 4BD1. From Memory it was a Safari, suited for the V8's.

Cheers.

I tend to agree with Jeff - the turbocharged 2.5 probably puts through as much if not more air than does the N/A 3.9. However, the N/A engine is probably more sensitive to a restricted intake than is the turbo - given a restricted intake (within reason) I expect with the turbo it will simply mean the wastegate will close a little and the turbo will make up for it. Of course, if the turbo has no spare capacity... but if that were the case, there would be no more power to be gained by "tweaking".

I am guessing that perceived lack of top end power from the fitting of a snorkel may be as much due to increased drag as to pressure drop, although this will have some effect.

A point I would make is that fitting the pipe to the snorkel in place of the dump valve does not seem to me to be a very good idea - for two reasons - firstly, the Donaldson system expels a large proportion of the dust it traps though this valve, and secondly, where the normal intake points at the element, the element is protected against damage from incoming objects (grit, water drops) travelling at high speed, where opposite the dump valve, the incoming air will be directed straight at the paper.

Mine is made from Vinidex stormwater fittings. I sent photos to Echidna and he was going to post them on the forum.

[Blknight.aus]

is this the point where I offer to take lots of pics of the ones at work?

...and be thankful you don't live in Soviet russia where such an activity could see you 'disappear' to a labour camp in Siberia:p

Surely if you just maintain or increase the same internal diameter of the pipework an exhaust or PVC snorkel will suffice, as long as all the joins are sealed properly and the ram or cap disperses any rain water anything else is just purely asthetics.
