Outer Limits 4x4 Board

Here are some fotos and a bit of detail on how I did my snorkel.

The piping is welded up from 3 inch Aluminised mild steel, using mandrel bends and a 2.5 inch reducer in the guard space. I used wire reinforced rubber inlet hose for the ducting as per the Ferog.

We cut a 3 inch hole through the guard and die grinded it out to fit the greater diameter of the mandrel bend to get it close to the guard. This I lined with pinchweld rubber, left over from a job on a previous car. The snorkel is really tight fit into the rubber, stopping any vibration in the guard. The rubber hose on the inside of the engine bay stops and other movement. The upright of the snorkel is mounted to the A pillar with two tabs and six stainless ten guage screws. There is no movement in the snorkel, if I grab the pipe and shake it the whole car moves!

In total there were two 45 degree bends and one 90 degree bend. The cost of the snorkel was just under $270, the head was second hand from Surfection (thanks mate).

I got the work done by:
WINDSOR EXHAUST CENTRE
13 Windsor St Richmond 2753 (02) 4588 5533

I highly reccomend these guys for exhaust and pipe needs.

I then gave the pipe a couple of coats of Silver Hammer Tone paint. This is a thick plasticky paint that dries with a funky rippled effect that resists stone chips and hides surface imperfections.

I am running a uni filter in the standard air box having only removed the original cool air duct.

All in all I am very happy with it and as Emma said you can hear the induction roar nicely. The best is when you open the throttle fully at low revs and you can hear each roll of the cam opening the valves!!

Hehe...

(By the way, If anyone is interested in buying a bull bar, I am considering selling mine, $450.)

Good job Croz.

Can you notice any power change once you get a bit of speed up?

Havent noticed any real change as such. I might play with it on my next trip on the open road, to see what happens. Also heard that turning the snorkel head backwards is advantageous, might look a bit dicky though...

Wouldn't that create a vacuum (or low pressure) in the head and reduce power at highway speeds:?:

I thought people just did that if they were expecting to drive through a lot of heavy rain?

The snork head has a channel that rids water out of the ram at the back, so I dont think it would matter.

I have heard this more than once from different sources, but wont know till I try it.

backwards stops it from getting caught up on trees n stuff, most of the ones i've seen wit it backward were rockcrawling or not goin real quick, so no vacuum from speed.

also run it backwards for LPG !!!
to much airspeed causes problems !!!

nice job croz!! looks great for a home job, if i didnt know u did it id say u had it done

btw my mates run their snorkels backwards when we run dusty roads to minimise the amount of dust entering the filter.

also did you get your new suspension fitted? cos those rear leafs still look straight to me

bling bling croz get some purple polish on it give it a real mirror finish

Owen, the rear leaves are on order, bout another week and they'll be ready. I did the shocks tho, such an improvement, I dont get seasick driving my car around the burbs any more.

Emma, there aint nothing purple round here!!

hehe!

forgot to mention, looks sweeeeeeeeeet

wow... looks great croz!!! gonna be a while before i attempt to fit one to my rig but again... looks great. makes me a tad jealous...

Hey Croz....wanna come and fit one to my roza now please

Thanks for the compliments all, sorry Kell, I aint taking orders just yet...

PERFECT WORK, Croz !!!

Nice, work Corz indeed! I've made one up very similar to yours but my welding.... well yeah. Lets just say when you use normal gasless mild-steel wire on stainless pipe, the end result isn't that pritty, but eh, it does the job.

Now if you really want to cream your pants, run your flexible strait to the plenum, bypassing the air box and the box ontop of the rocca cover. Then stick a pod filter ontop of your snorkel where you have your air intake. It will sound like a rally car. Thats what i'm running at the moment and when ya gas it everyone turns and looks for the noise but they don't think it me. Its perfect!

DON'T RUN THIS SYSTEM OFF ROAD THOUGH. MY ENGINE LIKES EATING DIRT, I'M SURE YOURS DOSEN'T!

Dodgey Dave
Strikes Again

Just out of interst what did yours cost you to make?

Dave,

Mine cost just under $300, including the Head and paint.

Be very careful running the inlet as you described, the dirt is a real serious risk.

I remember once reading in Hot 4's a test on the different inlet setups and they found on a dyno that removing the inlet system to fit a pod can degrade the performance of the engine. There is a kidney shaped chamber on the inlet near the box that apparently has a vital role to play, not sure what it is but I dont wanna muck with it.

But true, the noise is awesome. I had once apon a time a stroked Gemini running twin side draught 40mm del'ortos (quad throttle) just with socks for filters on trumpets... that had a mean induction roar! Would love that noise offroad!

if thats too exxy for some and looks aint that important i have the plans to make a pvc snorkel for under $120. all parts are available from bunnings except for the head go to www.groups.msn.com/EXTREMEOFFROADPHOTOS and look around ya will find the details and some pics of what it looked like

You might risk cracking the mounts or the pipe using pvc, especially if you are on heavily rutted or rocky tracks, or if a large rock kicks up...

If you want a snork and looks aint important, make it out of the reinforced inlet pipe used for the duct from the snork to the inlet, it will conform to any shape and wont fatigue.

And this way you get the cool rally look as well. Check out Otis in 4WD Monthly.

Lookin nice Andrew, like it.
