Let the tinkering get serious!!....

To say I'm hanging is an understatement Josh, but it's taken a lot of tangents to come up with the right solution to the DPF, and I'm hopeful this is finally it. Glad to see Gav working his magic on your beasty.

I took a video if the induction noise in my TDI, it gives you a fair idea to just how crazy it really is, and I drive it real quiet in carparks and other public enclosed spaces, but I'm certain there's a lot less restriction between the intake and the engine than VW delivered it with!

The filter I am using made a lot of difference to the induction noise, as it has an open front design.





I've gone back to a K&N oiled one, as I was finding some fine dust in the intake from the Apexi, even though I've been swapping them out at about 30k's. I'd rather possible MAF issues from the oil over dust chewing out the poor TDI's innards.

Nice tractor!

awesome induction noise! Looking forward to doing the same on mine!

Spent Saturday arvo making up a jig to fab up my experimental DPF dump pipe. My plan is to put the experimental partial flow core into the stock housing, fix up the restrictive outlet, and bolt it up to the 42DD mid pipe where their dump systems join. I based the wood jig on the Miltek delete pipe I have currently borrowed, and the stock DPF I have been cutting up.

And here is the challenge, to get a flex and 3" pipes between the DPF body, and the 42DD flange.







Amazingly there is a ton of room below the DPF outlet, and the only real concern is the final pic showing the steering that the stock pipe weaves around, when viewed from the front, directly underneath - the engine is at the top of the photo. The only point that gets close is right down near the 42DD flange, so I'm quite confident a decent pipe will fit with nice mandrel bends straight out of the DPF cannister.

Good stuff Greg.

Get that finished off this week and we can tune it the week after when I start up there!!

Job came through then ol mate? You gonna commute via plane for now?

I have to organise my custom DPF core Gav, but as soon as that is here and I weld it all up, she's all yours.

I can get cores made in different % flow, so am going to try a 50% and see how the DPF delete tune goes with it in place. Will still soot a little, but should be half as much as a delete car, and with all my extra breathing mods, should be less again, especially on water meth. I'd like to be able to offer a high flow DPF pipe that suits your "delete" tune, and hopefully it's something we can get clean enough to pass transport / public acceptance. That's the goal anyway....

Should flow OK, as the plan is 3" DPF out, 3" mid pipe and 2.5" axle back, all straight through. I want a funnel out of the bottom of the DPF, the stock pipe is just horrible, and crazy given the space there is!

The great news is these cores never clog, so there's no need for active regens, passive is plenty.

Fingers crossed!!!

love your work mate, you should have plenty business in years to come when all the DPF cars start dying and needing new ones....

Nice work, Greg.

pretty loud, my mk3 was similar when I had a pod on it but i ditched it because all my testing showed I got more power and better spool with the stock air filter.

anyway, good to see dome devlopment work going on

I'd love to see back to back dyno tests with the pod induction kit and the stock airbox
