pod filter

[mikinoz]

you may have more more KW - but I have no DPF to plague my mind of lost KW's...

I have 2 more mods in mind that I am keeping to myself until I can see if they make a difference (in the interest of looking foolish mainly)...

I hear ya mate, but APEX'I know their stuff. It's designed to flow air smoothly on the inside where it counts. A front cap isn't a silly idea though...but you have to wonder why APEX'I do it this way to begin with. These filters are all the rage with the Supra crowd, and are a dry filament that doesn't kill / upset the MAF as oiled ones can do. Downside is they are a throw away $80 item.

I've considered a 100hp NOS shot too....

Given that you are 'only' running 2.0Tdi........might it be worth considering air boxes from other larger engined VW TDi's?

The T4 2.5TDi airbox takes air in direct from the outside on the drivers side fender and down at the bottom of the box.....the air runs pretty much in a straight line from the intake all the way to the inlet manifold......the filter itself is fairly massive and I had one filter that lasted 60,000km and still the air filter monitor didn't trigger.......the UK boys have been modding their T4 TDi's out to over 100kW without running out of air too...

so the place i got a quote off for a pod filter said they had to ring a supplier to find out info and would get back to me
so i gave him a call and said he cant get the part

so...

My other thought is that bigger DPF's if not already out there will be forthcoming from VW, and perhaps upgrading to one off a Tourag or something would give a much lower pressure drop whilst doing the right thing.

I don't know whether the DPF on the Transporter 2.5 TDI like mine has better flow than the 2.0 GT TDI or not. The motor in mine (2.5l 128Kw, 400Nm) didn't rev out as well as the GT TDI I took for a test drive (mine seems to peak out at about 4,500rpm), but mine did have better torque at low revs (below 2000rpm).

The Touareg and some Audis have an optional 3.0l V6 TDI motor that produces 150+ Kw and 500-550Nm of torque, so the DPF off one of those might flow more than yours. I have vague memories of a larger capacity Audi V8 TDI too, and maybe even talk of some monstrous Audi V12 TDI.

There is also the 5.0l V10 TDI from the Touareg, but I'm not sure whether that has a single or dual DPF system (it is basically two 2.5l 5 cyl R5 TDI engines stuck together, and may have 2 separate exhaust systems).

So there are a quite a few VAG engines that might be potential donors

All very interesting. In the end it comes down to flow benefit vs hassle / cost, and I'm sure the cost of a current DPF will be a factor. Thanks for the tips all the same, will put my ear to the VW ground.....


Guys ditch the Maf grid once you change the airbox, my car hasn't missed a beat, economy is still 850k's per tank which is clockwork for me, and I've Vag-com-ed it every arvo and there are no errors at all. Idle quality is as per stock, with no hunting or hesitation. Pickup and revving the car is noticably better, mabey it's largely just the sound, but it sure seems extra willing. Can't wait to sort out the other side of the turbo now!

Could you test this empirically by timing how long it take to go from idle to 3k rpm in neutral or similar? It'd be interesting to develop tests for this observation at least!
