Snorkle intake backwards, better fuel economy....GU8
OK so the past three weeks i have had to drive 400km intrastate and i figured i would do a little test.
I figured i would see if turning the snorkel intake to point backwards made a difference and without a doubt, on the highway it has made a HUDGE difference.
I did two trips with snorkel forward, diesel from the same stattion, 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.
All runs were done with cruise control on the same road, under pretty similar conditions.
SO i have left the snorkel backwards around town, and i picked up about 100 kms out of both tanks.
Anyone else found this?

Hi WogRus,
Never tried it but the snorkel will be facing backwards tomorrow. Have a 400k trip to do so will be a good test, thanks for the tip.
Cheers

That's very interesting. I would have to guess, the computer would give extra fuel to burn with the extra air being forced in. I wonder what I'll find with my petrol, carby engine when I fit a snorkel.
My advice is: not to follow my advice.

well this is interesting... on thursday the 20th of june i will be doing my usual 1400k trip from Newman to Kalbarri via Coral Bay.
i normally get about 14 ltr per 100k and the last trip was after a service and the induction system cleaned out i average 15.5Lph ( mechanic said it should be better than before??? hmmm )
so i will turn the head around and do the trip and report on here my findings..

No loss in power that i noticed, but i do have an exhaust on the car and that helps i guess. It goes against what i would have thought, with the ram effect and so forth, but maybe, just maybe, the troll prefers it teh other way.
Added bonus, open the passenger window and the howl from the turbo and so forth is soooo addictive.

You dont get ram air as it stops at the filter and can only suck what it needs.
Need a few more results first I think

Might give this a go, very interesting. I suppose instead of ram air it would be collecting the vortices created by the snorkel head.
