Title: safari snorkle problems
Post by: andygod on December 04, 2006, 11:54:37: I have a 3.5 efi v8 fitted with a safari snorkel; if I try to drive with the air scoop pointing forwards the vehicle cuts out. The engine is fine with the forward facing scoop when the vehicle is stationary. Because of this I reasoned that the scoop was having a ram air effect and pushing extra air past the airflow metre. The simple answer was to reverse the scoop so this I did and things have been fine for a while. The other day whilst laning in Wales we had high winds blowing from behind which had the same effect on the snorkel. This resulted in me having to disconnect the snorkel in order to get the engine to run properly. Does anybody else have any experience of this problem and any fixes? Will a mushroom top fit a Safari snorkel?

It needed to have a snorkle fitted but in the end I made my own.

In researching this on the internet, I found that the majority of LPG owners had the scoop at the top of the snorkle facing rearward for the engine to run correctly.

Post by: thermidorthelobster on December 04, 2006, 21:33:22: Basically, because the amount of gas sucked in depends on the venturi effect which in turn depends on the amount of air coming past the mixer, LPG systems are very fussy about the air flow. So much so that on a system without a snorkel, if you stick your hand over the air intake so as to slow the flow down a bit, the engine will probably stall as the mixture gets all messed up.

It's possible to tune an LPG system so it will work well with a snorkel, but I'm told it's not that easy. The easiest solution is to have a system of disconnecting the snorkel (eg by taking the air box lid off) when you're running on LPG, and make sure you're on unleaded if you're wading. Things like the vapouriser won't like water too much either.

???

Post by: Range Rover Blues on December 05, 2006, 01:07:42: Yes, you'd get a better balance of air flow (a bit like a boiler flue).

Personally I'd love to fit multi point to Blue but i havn't the cash right now, I want that tank out of the boot too :evil:

Then disconnect the snorkel when on road and run on petrol when the snorkel is connected. I use petrol off-road becasue I get more torque and far better throttle response.

Post by: ChrisW on December 06, 2006, 12:44:40: I think Andy is looking for a cheap quick fix that can be fitted and forgotten and that doesn't involve fiddling about under the bonnet everytime you go off road or near water :wink: hence the question with regards to whether a mushroom top air intake would fit onto a Safari snorkel :?:

Post by: Range Rover Blues on December 06, 2006, 12:47:13: Sorry, I didn't think that a Mushroom top wouild be cheap enough :oops:

Anyway, no such work as Can't.
Title: safari snorkle problems
Post by: Lee_D on December 06, 2006, 14:18:06: Yes in the snork if possible, many 101 owners do this and it sorts problems on standard Air filter systems. Worth a try.

Post by: andygod on December 06, 2006, 15:51:43: I think I'll get a mushroom top and give it a try, thanks for your ideas and help. I'll let you know how I get on just in case anybody else has the same problem. :P
