Sorry.....The thingy that goes wooochhhhhh then.

its cool, things that go wooochhhhh are nice to hear.... to be honest I don't know what it would be on a new TDI really. there's no "blow off" valve either. But in the context of a new diesel and induction noise, i get what your talking about.

I've often thought it might be a bit of a 'choking' sound as the throttling flap for the EGR valve closes a bit when the accelerator is let off to start sucking exhaust into the inlet.

[ForceFed]

Thank you for your explanation. Seems more logical. I'll go with that.

Can't be the EGR flap Aydan, mine is hanging in the breeze, yet the noise remains, and is in fact stronger without it.

I think you can actually hear the VNT vanes "flutter" on back-off, it's amazingly apparent with my new x-force K&N "open front" pod, and you can pretty much get the typical ricer blow off valve sound between gears if you short shift. I have to say that my TDI is borderline ludicrous now and I get guys driving just in front of me looking back, for it sounds like the suction noise on mad max, but without the supercharger whine. I'll have to video it, it's a bit much really, but rather funny for a tractor! Aty least I am sure I have a low restriction inlet!

Keep up the good work FFed, you and Poyta have made me make more of an effort on the appearance front, been out with the spraypaint a little myself. Appreciate the action in the oiler section : )

[gldgti]

yeah second that. Props for you guys doing something... anything.... to your diesels. its nice to see something happenning around here.

You can actually hear the VNT vanes "flutter" on back-off,

I can't imagine it Greg..... the vanes being all the way on the exhaust side of the engine.... I just can't resolve that one could hear the noise made by the vanes at all... But, I'm sure you get the compressor making all kinds of strange noises when the engine slows down suddenly but there's a lot of boost backed up in the inlet pipes....

anyway, here I am going off topic again.... sorry.... don't take my post as inflammatory, just trying to find the real explanation for this cool noise

The turbo definitly flutters, ive had the intake off one at the turbo listening for a noise and there was big flutters, although this turbo did turn out to be stuffed

[Greg Roles]

...actually good point Aydan, you're right in that it wouldn't be the VNT side of things, but I think it is the VNT vanes affecting the inlet impeller speeds, there is a definate flutter, and I can play with it to get that full F&F Paul Walker sound. I will video it for you, it's very obvious on "tinker TDI".

back to the beginning, i have a tdi as well. im getting eibach sportlines, already have 18's. but am wanting to get the rears squished a little by a spring man iin newcastle. im wanting to drop them down another 10-15mm.
i understand it will reverse rake slightly i like it

how much room is there between suspension components in the back. should i stick to 50mm?

HELP!

[ForceFed]

I guess you could always just chuck them in and see how you go. Eibach Sportline and H&R Race have similar specs I believe. I'm running 235/35/19 with not too many troubles, odd little scrape here and there but nothing major.
