Snorkle intake backwards, better fuel economy....GU8

[nissannewby]

What sort of driving were you doing prior to your comparative trips? I know mine will be better if it gets to sit on a set speed day in and day out but driving around town I use more fuel.

Snorkel forwards helps a tiny bit but facing backwards doesn't make it any better. Factory snorkels are restrictive so spinning the head won't make a different. What I noted in my first paragraph will though.

I turn mine around when u remember and when I am in convoy on dirt/dusty tracks only to try and reduce how much dust enters but not sure of the fuel and power diff. Had it facing backwards for a couple of weeks and can't say I noticed any diff in either, the thing was like said before the turbo whistle did sound awesome but the misses didn't like it.

The driving was all compared on the highway, exactly the same route and so forth. The comparison has taken a whole month to do so far, now on tank 5 see how we go

That's what I mean. I can do the same in my 4.2 it will always be better over long distances. For eg I have moved house and the mrs drives my patrol to work. It uses less fuel while the distance is further simply because she can sit on a set speed all the way to work now instead of stop start traffic b

ok sorry you need to go back to page 1

All the test were done on the same bit of road under similar conditions, all were done on a highway run, ie, the comparison drop is for EXACTLY the same conditions, road and the like over 4 trips ie four full tanks.

I did two trips with snorkel forward, diesel from the same station, similar day conditions, managed 12.65 average at about 120 kph,

Did two trips with snorkel backwards, diesel from same station as always, similar day conditions if not slightly cooler, managed 10.2 l/100 at about 120kph.

Air density/pressure may play a small part , cause we all know on cool crisp nights the Patrol flys
I'm not sold on this but you say its better ,Its better. but I just cant see how.

What ever your smoking. I want some. You sure you didn't fit Hi-Clones as well?

Come on guys, why would i be bothered to post if i didn;t find any differance.

[mudnut]

They're just jealous, that you get better mileage.
