Pros, cons and method of drivers side snorkel on GQ

I am soon to build my snorkel, and whilst thinking about it all, i wondered about a drivers side snorkel. i think there is just enough room to squeeze the 3 inch pipe between the brake fluid bottle and battery (might have to squish the battery tray side inwards slightly to clear the wires).
Having the snorkel on this side would benefit air intake temp as the intake pipe will be well clear of the exhaust. Downsides i can see would be that i would have trouble accessing the linkages on the carby to clean them and/or lube them.
What are peoples thoughts, or has any1 done this? I'm doing this on a dual fuel, so my air cleaner is easy to just turn around and point where i want it to.

The only downside would be vision champ. I do think that it is a large downside too.

what about other cars having it (cruisers come to mind) having it on that side? is it much of a problem for them?

I think your nuts.
The vision is a big problem for a road use.
The factory plumbing is good for the left side (but can be improved)
Use metal heat shield or blanket on the exhaust (not heat tape)
Heat shield under carby.
Upgrade your cooling system.
Go EFI....

I was looking at the same idea tonight. You could have flexi pipe so you could take it off to get to the carb.
With vision couldn't you position the pipe in the right spot on the pillar so it blocks your vision the least?

You certainly could place it in front of the pillar to give you the best vision.

all our troopies at work have the snorkells on the drivers side and i have never noticed it impeding on my vision, sits directly behind the pillar so can hardly see it. does have a bit of an annoying whistle if you have the window down on the freeway tho

hey i'm hearing about people using 3 inch pipe for their snorkels and stuff and the arguments being it'd look way to big on the car, well why not run 2 1 1/2 inch pipes, one on top of the other kinda thing, it wont stick out the side of the car as much or you could even use 2 inch pipes which would give you the overall diameter of 4 inches, now thats some serious air flow!!!

Hi,
You can't just add the diameters, it's the cross-sectional area that matters.
So two 2" pipes gives you less airflow than a single 3" pipe.
Cross-sections are:
Code: Select all
1" 2026 mm2
1.5" 4560 mm2
2" 8107 mm2
2.5" 12667 mm2
3" 18241 mm2
3.5" 24828 mm2
4" 32429 mm2
4.5" 41043 mm2
5" 50670 mm2
To look at it another way - every time you double the diameter, you get four times the air flow.
Having said that I don't personally believe that a single 2.5" is too small for a TB42, because it is quite a low-revving motor, but others may disagree... on the other hand I think the passenger side is a better place for a snorkel for the same reasons stated by others.

im
running twin 3" snorkles on mine, vision isnt a problem

another thing that was pointed out to me was that access to the dip stick would also be a problem, the was i was thinking of doing it, so after all this, i think the way to go is passenger side, go into the gaurd early, then go inside the gaurd down to the existing hole so that i dont have to cut through any strengthened bits if the gaurd, and make a heat shield to suit my extractors.

Can I order one of those too?

Sounds exactly like the airflow snorkel on my SWB maverick. Goes in early, then there's a pipe inside the guard that goes to the stock hole.

looking at the pic in ur avatar, yes, it goes in earlier than the hole on the inside, but i'm thinking of going in basicly as close to the A pillar as possible.

Yeah.. I think the only thing in the way is the electrical aerial so if you don't have one of those (or don't mind ditching it) then you can probably do it. I am just trying to remember if there was anything else structural in between and I think that *maybe* there is also a metal piece to support the mudguard that would make your job more difficult.
You might want to take a look inside before you start buying materials.
