Internal Snorkel mod.

[makeitfit]

Decided it was time to make a snorkel for the Trol. I just don't like any of these massahoosive external ones that go ALL the way down the wing plus they're stupidly expensive:/
So how hard can it be ?
Bought some 3" silicone hose off fleabay in sexy black 2m long £38
Then set about cutting up the air filter housing as follows:


This will be the new way in ish

So next job, drill a dirty great 85mm hole in the bulkhead where these holes are

Here you go, and then file off the edges nice n smooth

To make a nice collar through the bulkhead I found this in me garage It's a 4" soil pipe adaptor for a 1 1/2" waste pipe, ideal

Here it is in place ready to drill the b/h so I can bond it in place

I drilled a big hole in this too so the air intake will fit through it a bit like this

So as that worked so well I bonded it in place with Tiger seal and a few screws to hold it in place till the goo cured. That'll be totally water proof in an hour or so

Next steps will follow in post 2 as there appears to be an image limit per post :/
Back in a bit lol

Next the air filter box needs some modifications Basically cut off the bend bit and then cut off the square end, as that bit will be in a new position on the box.

Then I grafted on the square bit onto the box and riveted it in place , again using tiger seal to seal it all up.

Then I cut a bit of old tread plate to blank off the old intake hole. Again, rivets and tiger seal do the business

Refit the filter box back on the Trol

Here you go , plastic pipe back in place and it lines up a bloody treat

Next stage will be the silicone hose connection and then routing it through the dash and up the A post.
It'll then go onto a roof scoop made out of a bonnet scoop like a scooby or similar
Watch this space for the next instalmen

So far so good, I like where this is going,
keep pics comming please, unfortunately, A snorkel is a snorkel
Or is it

[makeitfit]

Will do but it's come over all night time here lol

Right then , did a bit more today and got the inside sorted pretty much. Took out the glove box and the grab handle in readiness for hole cutting

With the air vent out and working from under the dash, there's just enough room for an 80mm hole It does get close to the grab handle but not too much.

Again much filing and smoothing required so you don't damage you pipe Then gently insert your pipe into the hole a little wriggle and twist a bit , then ahhh it's in

Pull it through slowly so it can be passed above all the heater blower gubbins and then carefully out the B/H collar . Then you get this the other side .

Back in the glove box zone I got a suitable zip tie to hold the ducting up out the way of the heater controls and keep a nice gentle curve.

Then the glove box innards need to be trimmed a bit to allow for the ducting, didn't loose too much of it, still room for man things

The ducting is now up the A post and zip tied to the roof till I can get to the scrap yard and liberate a bonnet scoop. Got the exposure all wrong but you get the drift.

Opened the back window and took it for a test drive
Sounds sweet

WTF..
I'm with you on not liking the big long snorkel along the 1/4.. But f**k me you have to be kidding!!! (clearly not..)

I dunno about anyone else but there is so much wrong here.

1 - you cut threw your firewall... Compromised the integrity, and a massive defect..

2 - you ran it inside the cab!!! What happen when the thing back fires?? Or a valve sticks open slightly.. It's a highway to disaster..

And 3 - how the f does that look better than the snorkel along the 1/4????

1 Aye, just the same as heater hoses, wiring loom, air con etc ?
2 Not had a diesel back fire yet, but thanks for the warning.
3 Ah well each to their own lol It'll look neater when it's all clipped in place properly

This Member is in Wales UK and does not have the same ADR restrictions that we have here nor does he have access to ANY of the after market off the shelf stuff that we have in every shop we go to in Australia. His specialty is Outside the Box.

I agree i am not a big fan and when looking at it i have to say the Turbulence noise through that hose inside the cab will be massive Loud! If you have a Turbo it could be wicked though! If you have a Turbo i soooooo want to here it spool from inside on a Audio track please!!

Interested to see how you finish it off mate.

Cheers MR

I have seen this on another forum on a TD42 running in excess of 200hp in a GU. The only difference is I think he has just run it into the cab and it stops where it come through the firewall. The owner reckons it was loud as with the turbo drawing so much air he put a filter on it which apparently quietened it down a bit. MR im pretty sure a member of said forum have a look I think at tye1986 build thread on patrol 4x4.

I've done this mod on my old Nisaan Terrano, and that was turbo charged. It does make a nice drone in the corner of the truck but not obtrusive at all. Remember the intake will be a scoop on the roof as on Subaru Impreza for example. The silicone pipe , although flexible, it's still pretty hard to bend and relatively smooth inside. The new route in is now nice and smooth compared to the stock Patrol intake box in the wing and then the twists and turns into the filter box. I'll be doing a pressure test when I finish it so I'll be able to give you guys an empirical answer to how much drag there is in the pipe compared to the stock intake
This is also legal in the UK and listed on my insurance modifications list.
Thanks for the back up by the way "mods" cheers. No offence taken by the way , I am welsh after all lol
