diesel NOISE REDUCTION!!

hi,
i recently bought an Alfa GT JTD. it is absolutely stunning, a pure dream of a car! i love it to bits, but there is just one problem... the noise the diesel engine makes is driving me CRAZY!!
Everything else is perfect... is there anyway to reduce the noise level the clattering engine makes?
Someone PLEASE HELP!!

Cheers.

go even faster then you can turn the engine off when you get there and enjoy the silence for longer.Yes,I agree at first the idea of a diesel Alfa was a weird idea but I save money compared to the dull Audi I had before.Now and again I think,has it got noisier? But I'm sure it has'nt

What he said.


If there were no downsides to driving a diesel we would all drive them.

oh yeah the new ones are ok, but if you want it to sound as quiet as a petrol, like the guy above seems to want, there is only one thing to do

i personally dont mind diesels or the noise they make, but prefer petrols, and the extra revs you get.

guy above thinks his diesel is noisy, should try the old 1.8 peugeot diesel (we had a 405 with this engine, noisy, yes, but by christ it shifted), or even better, the perkins diesels in the maestro and montego, now they where noisy

Remember them well, we used to have a Montego diesel pool car at work. We used to hate the thing with a vengeance. Also had diesel Citroen BX's which were reasonably fast but were horrendous. Nowt like modern turbo diesels. Got to say my next car is back to petrol, don't do the mileage to justify a diesel

Not much you can do. It will clatter on short distances. Once the engine is warm the clatter is almost completely gone though.
The only diesel engine with good sound i know of is the 3.0d in my fatherx BMW X3. That is one hell of an engine. Not thirsty at all - heaploads of power and it even sounds good if you floor it. In winter even that one will clatter on startup though.

I must admit the diesel noise is a bit, well horrid but I have t agree that is better than the french and german (VAG) equivilents. I fitted a K&N hi flow filter (not an induction kit) which has made the turbo suck noise more satisfying while keeping it looking standard. TomFromTelford has fitted a sport exhaust to his too which makes it sound much better. He has some soundbites of it on youtube somewhere which make it sound much better!

Althernatively you can just do what some of us do and use it as an excuse to have more than 1 Alfa!

BMW E12 M535i, JC racing diff, Gaz coilover, Powerflex.
Alfa 156 GTA, Q2, Super sprint, CF2, EQ, KW coilovers, Eibach rollbars, Powerflex.

If you want a quiet diesel, the only one available is a Honda. I used to have a 2.2 diesel Civic and it was really quiet. New VAG common rail units are not bad now either

the honda ctdi's are pretty amazing for there lack of a typical diesel noise, and apparently the i-dtec is even better.

wonder if they would sell there secret, or even tell us what it is for that matter.

There's an explanation on their website. Click on the "discover Honda diesel" link on the centre column, and then click the change button and read the text above the engine for how. Music will drive you mad after a while though...........

On my GT I have found a button that almost elliminates the noise. It's a standard fit.


It's located next to the radio.......it's called "volume+"

Add to that "Top Gear Driving tunes" and your well away!!!!

I just changed the exhaust for more growl less tick/clatter.

if you get a lo of ticks on initial move off that could be the aux belt tensionors.

These would do the trick and have the added bonus of removing missus induced earache..

A modern Alfa Diesel is actually pretty quiet. Had a ride in a mates 1.9 JTDm 159 manual. I thought....hmmm, can't be good. But in fact, very very nice sound, tappetty at idle - and a HUGE punch from 1st to 5th on the box. Awesome, I loved it. And I also loved a ride I had in a Diesel VW Phaeton, one of the first in NZ, this thing is sensational, with the big and the little turbo, it moved like ... well.... a freight train on Steroids. Yes, I do prefer to sniff petrol, but a mature European Diesel by Alfa or VW is not totally bad.....

I agree, I love the sound of my JTD 16V, cant understand why anyone wouldnt.

Doesnt sound as good as the 2.4 though.
