I have the pd160 Cupra tdi it was standerd with just a jr cone filter fitted a d when u let off ur throttle on that at 2 k revs that makes a dump valve type sound and defo does not have a dv fitted. The tdi engines require a constant pressure behind the turbo if u dump the excess boost pressure in the system ur turbo is going to have to start building up all pressure again there for u would lose power completely not a good idea on a tdi engine unless ur running extreme power ie 300 bhp plus
 
Lol nice multiple quote reply. Can't remember differences in turbo think its on Wikipedia lol but there is no need to change the air induction on a tdi as it has too much air intake already with the standard box

;)


It made me feel dizzy

;)


Panel Filter perhaps but going by info/feedback on here the standard filter was just as good. I can only recall one member who fitted an induction kit to an FR TDi.

cheers mate, i'll give that a read in a sec

so anyone who is running a DV on a diesel is either pretending to make themselves sound better, or has some serious power? - probably a nice idea idea actually

this one i saw definitely had a DV though, you could hear it from the other end of the car park, it was loud enough to interupt conversations with people standing a couple of meters away because you couldn't hear them over the TSSSSSSSSSSSSS
 
on a side note, i've just remembered something else the garage told him (him being my mate Dale)

they had a picture of a leon on the wall inside the garage that had its windows tinted (that they'd done) as a sort of promo - the guy who was looking Dales car said "thats a diesel we remapped the other week" and Dale said it had a full K1 kit on it. did the diesel ibiza ever come K1 kitted? or is this further proof that the garage just had no clue

EDIT: sorry for all the questions, i dont know much about diesels, or leons

The K1/Aero/BTCC kit can be bought from a Dealer so any Leon could have one on it. Latest model FR+ Supercopa comes with it as standard.

Yes any body running a tdi engine with a dv is trying to make them slefs look and sound good but not having a clue how the engine works or they are running some serious power under the Bonnet but even still then I would not fit one.


Also U said about air intake in my opioin I would change the standerd air filter to a cone filter to produce more air intake

Ah right, really? thats good news, thanks for your help mate – hopefully the kits not too expensive, because Dale needs it

Well that’s it mate - they suggested an air filter and DV in order for a stage 1.
As I say I’m not too clued up on diesel engines. Thanks for your help

Also, fancy trading cars? I’m serious. I’ve always fancied a yellow 6L

Not a dv no. but I would change ur standerd filter to a cone filter the air flow is a lot higher Flowing than ur standerd filter. I would also serjest to get a jr cone filter or green stuff over the others look at my thread under this and u will see mine

i got that now brotha ;)
but what i'm suggesting, is me and you trading cars
 
Its not coming to an abrupt stop, when you let off the accelerator you’re closing the throttle body and reducing the air flow massive amounts. The blow off then opens and is dropping back pressure to stop the air forcing itself back out past the turbo in the opposite direction.

With the turbo being an impeller that will cause the turbo to slow down rapidly, and if there is enough pressure it’ll cause the turbo to stop and spin the other way. So you drop the back pressure straight away, allowing the turbo to freely spool, then when you’re back on the power the turbo can jump back into action and continue to draw air in – so with a performance blow off, you drop pressure quicker and more efficiently, meaning your throttle response improves since you’re turbo is more active, and you probably get a slight acceleration increase since you’re not having to waste time spooling the turbo back up, reducing the ol’ turbo lag

That’s the way I understand it anyway.


No I was on about the funny noise you get on a tdi with a straight pipe, that's the impeller chattering due to air on either side not being equalised, I don't know much about dump valves though, I think that's obvious lol :D
 
Blow off valve opens when the throttle body closes. And diesels dont have throttle body, right? So it's impossible for blow off to work on a diesel unless it's operated electronicaly which is a bit pointless at the same time.
Company talking rubbish imo.

That's right on that model of car but on some this that's not the case but it will make u lose performance on any tdi engine there for making it a pointless mod
 
I disagree with the tdi engine being a high pressure induction system

Yeh but it's forced induction and the filter doesn't prevent any air getting through till you've spent a fortune on other things. You'd be lucky to ever need rid of it really.
The cone filters sound good on the likes of a VR6 etc but I can't see any point on a tdi.
 
I am not going to say putting a cone filter will actually gain any power but it defo does a better job than the oringal filter due to it gives better air flow I know all the argueements about this subject there's pros and cons to both sides of opioins. So it ends up as a personal choice to what people want to do with there air intake system. Me my self I belive Jetex (jr) cone filters are the way to go.
 
Yeh but that's the point, it doesn't do a better job, there's nothing to gain at all unless you're seriously tuned to an extreme level.
If you want to have your cone filter that's up to you but it isn't a good thing. Most of them let to much through and the fine particles hit the turbo and the insides of the engine.
I can't see why you would fit one other than tidying up the engine bay but there has to a better way.
 
I have tested versions things todo with induction on the tdi engine people say they let fine particles through the filter but so does the standerd filter I test this by passing power chalk through i blow mechine with both filters stoping the flow for 5 mins I measures how much chalk had passed through both filters and with in a 5 min period the standerd filter had let 1.9gram of chalk power through the filter less than the jr. But at the amount of chalk that had passed through that amount of 1.9 gram was minimal

Second test I put both filters in front of the blow machine again with just normal air flowing and test which filter would fill up a large ton plastic bag first the jr cone filter filled up the bag in 74 seconds while the standerd filter filled it up in 102 seconds there for it does restrict flow of air
