Outer Limits 4x4 Board

Ok so i have a DTS aftermarket turbo setup on my TD42T in my GQ....

i took the factory airbox off the back of the motor and put a pod filter straight on the pipe from the turbo. It sounds way better.....

Therefore..... i want to piss off the DTS airbox that seems to go there and back again, but i have a snorkel...

so is there a cylender style in line filter that would be similar to a pos filter with a 2/1/2 inch opening at either end that would be suitable to hook my snorkel up to that anyone knows of?

any help or ideas of filters setups i can try would be great.

screwy

Make one out of 150mm PVC drain pipe, 2 blanking ends ( make one a screw end so you can open it up) and a couple of 3" flange/tube fittings ( I got one from autobarns or make them) each end. A K&N pod type in the middle and job done

2.5" is probably getting a bit small for a turb'd TD42 depending on what youre trying to achieve

I agree 2 1/2 inch is probably a tad small. I'm part way through making my airbox for my pod filter. I searched for ages for a paper filter that'd fit and flow enough air for big engines and they don't exist. The pipe style like clanky explained is good if you have the space but making a box with a perspex lid so i can see when the filter needs to be changed.

yeh.... well the factory pipe coming off the turbo is 2.5 inch.
It used to come out of there and into the airbox and the snorkel used to come into a second spout in that airbox and it looks like its making its way around the country and back lol.....

I have a 2.5 inch pod filter on there atm temporary till i work out how to get the snorkel back on, you can hear it sucking like no tomorrow so your right its probably not big enough....

i guess hense why i raised the topic....

BMC do a nice pod in a box setup that can be sealed easily, i think there three inch, but can be reduced

I don't think I'd be wiling to compromise filtration for a cooler noise.

I'd be keeping some sort of proper filter housing.

no shit..............

hense the whole purpose of this post.......


to put a cylender style sealed filter in with pod type setup rather then my " take up half the engine bay sqaure one "

Pod filters in cylinders do not filter as well as the square box you had in the car. Neither of them filter as well as a proper centrifugal filter like a Donaldson Cyclopac, even more so with a snorkel, where the pod just ends up copping everything that comes down the snorkel.

Pod filters are for road cars, not 4WD's.

How do I know this? I trashed a motor with a pod filter.

You can buy a 2.5" to 3" tapered reducing stainless fittings http://www.atlasmetals.com.au/Stainless ... ttings.asp
This will sort you out
The filter both myself and my bro have run for the last 50000kms in our diesels is an RU2820 K&N. Have done the Simpson, The Cape, Fraser and the high Country twice with no dramas and this was inside the PVC tube homemade housing. No water in - hey the fittings are designed to be water tight - and seals better than a factory plastic box. Cheap too.

I like the Donaldsons and the Fleetgaurds etc but they are just too big.

im happy to settle for any cylender style air filter thats " inline" directly with a 3 inch fitting on either side. A cyclone filter may do what i want.

basically, i want to " FREE UP " my air intake from the massive about of extra piping and restrictions that are currently there, without reducing the filtration effect....

a cyclone inline barrel filter may be good, im wondering what models of car and any aftermarket style ones there are that i can run......

Did you get a discount??

Is that to big? You can get multiple outlet direction options with the donaldson..

maybe too big..... dont suppose there is an easy way to find out the dimensions....

Its not just the dimensions, you need to match the airflow to the filter and they are just too big to suit a tub'd 4.2 - been there done that - no room under the bonnet for me

Just another option, one of the turbo mobs were using a modified factory pre-filter in their turbo conversions. I think it might have been turbo glide:



Not interested in a ZD30 box?

It is pretty hard to find a filter housing that'll fit and flow enough air so oiled filters are a better option. I know they don't filter aswell but they filter enough if kept well oiled and I have a foam prefilter over the top of my k&n and hopefully it keeps enough dust out. I got a prefilter for the snorkel if i do extensive dust. The better fuel economy should help towards the stroker kit when my engine gets tired.
In the end how much dust/dirt driving will you actually do?

Well this rig is not my daily driver, i use it for very few road trips, and wont do any dirt driving in it, and very limited mud as well.

it is 90 percent used to smallish ( less then an hour ) road trips to tracks and then driving rocky tracks.....

it simply doenst get exposed to massive high volumes of dust....

that said, im a firm believer that my filter setup works well currently, but i feel its very restricted and isnt direct to the turbo, so i want to make it free and efficent.

any type of cylender style filter housing with a 3 inch hole in each end would work well.

I cant use the ZD30 filter housing behind the headlight as i have duel batteries and there is no longer enough room.....

Im thining i can slap the pod on the top of the snorkel if i ever do really rough conditions to act as a pre filter.....

2 things

a) Your turbo can compensate for restrictions, I wouldn't stress. It'll work the turbo a little harder, but unless it's already on the edge of it's envelope, that doesn't matter. It's not the same criticality as n/a systems.

b) Read these then measure rather than guess
