does the brand of d.v affect the sound produced? mines from well lane turbo centre and i think it sounds too long, if i put a bailey d.v will the sound be differant?

sorry if its obvious....

dre

 

yes and yes and dont put one on!

 

i get an urge every month to drive without it, but i end up puttin it back on after an hour

sounds sooooooooooooooooooooo gooooooooooooooooooooood!!!!!!!

 

nooooooooooooo it donttttttttttttttttttt

it sounds like your a bus!! and it makes the ride so jerky!

 

fpmsl

i didnt really notice a differance in ride quality

 

i disagree. i think they sound awesome and they also have a purpose on high powered turbo applications - or so i understand.

I love the sound, wouldn't change it for the world.

 

I guess your both 16 ?

 

21, with a degree in computer science and philosophy.

what's the problem with atmospheric dump valves anyway. it's a sound at the end of the day. does it do vehicles damage?

 

I beleive it can in some circumstances cause the turbo to overspeed and that can in turn do damage.

I run 25psi on my Stage 2 hybrid T3 and don't/won't use a DV. ERST's do not respond well to the addition of a DV. FRST's are better but as has been said so many times they serve bugger all purpose on most road applications.

I would honestly not bother but it's each persons choice. I'd rather spend the cash on something that enhances the performance though

 

My understanding - which will probably be shot down in flames, but at least i'll be put right by the amount of knowledge on here - is dump valves were originally designed for very high performance engines running huge turbos with big boost figures.

Dump valves - atmospheric as opposed to recirculating were designed to alleviate the pressure on the system as high boost was unsuitable when a gear change happens. I've heard rumour of it stopping the fins on a turbo from shattering under high pressures but i honestly thing that's twaddle - either that or a very early problem within turbo development.

As for the sound. you can get valves that recirculate and give an atmospheric dump but i'm sure die-hard performance enthusiasts will lean towards completely recirc valves for obvious reasons.

I didn't realise there was so much of an anti-atmospheric feeling on here.

 

Dump valves were invented by Saab in the 70's as a Noise Surpressant device. The chatter was deemed to annoying for road applications, so they fitted a reciring d/v.

Do they do anything for the preformace, turbo life or reliability of your car?

Nope.

Do they sound stupid?

Yup.

Dump valves are also really bad for the MFi Escort Turbo. You'll notice the car runs alot better without it.

 

*hardware*

STUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUDE NT!

 

so why not get a dump valve with a hardish spring in it so u get the best of both worlds. will "chatter" down to about 0psi then dump

 

Ex-student. Two job offers, one with a rentacar company, one with an investment bank.

I like dump valves, i guess its just a matter of opinion!

 

what, 16 and driving an rst? hmmmmmmmmm

tis a matter of opinion. 99.99% of people i know LOVE the sounde of a dump valve. As far as im aware it seems only some people on here who loath them. At the end of the day i get fed up of lil 15 year old pikeys asking "is it a replica", so i just show em!



BTW it wasnt a "do you like dump valves" thread, if u read the 1st message i asked if differant valves make differant sounds...

 

I was driving when I was 11 So you could be 16 for all I knew Anyway that was just a huge generalisation of things that impress people in certain age groups. No harm meant

If your worried about the noise it makes stick a tin can over it , or go ask your 99.99% of people you know if they have one you can lend to try it out.

But the short answer is yes.

 

and i answered!

yes and yes but take it off anyway!

 

Dump Valves are

 

i've got a forge motorsport on mine and it still chatters its tits off.
when i took it off, as i'm not a fan. i lost 3psi so i put it back on and it went back to normal

 

dump valves are cool

no point arguin it over tho cos ya can love em or hate em

 

it doesnt really

its just cos you want to hate them that it "feels" better lol

 

never believe anything Mr McBell tells ya

 

aaahhhh the broom handle mod!

BROOM BROOM!

 

when i take mine off the only differance it makes is the revs stop dropping below 900 rpm when you change gears at full boost... with it on it just dies... i presume its because my d/v goes on for too long, its abit like ptschhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh hhhhhhh at full boost... thats why i want to try a new one

 

not thats cus its aint a double piston one which the rst needs! as it has a metering unit!

get a bailey one if ya have to have one! dv26 i think it is!

 

have you never herd of d/v elecrtonic controlers ive had one on for years and never had any bother on my erst stu sels them
at the end of the day its a matter of choice, i love d/v
and remember ford put one on the cozzy standard with just 5/7 psi
this arguments been going on for years ,
everyone has a differant story as to who invented them, i was told by castle performance that thay were invented for the ford rally team to help the big boost cars change gear faster so the impeller doesent slow down inbetween gears, but i suppose some one will have another story
at the end of the day loads or sold and every mag you pick up has a fetured car with one on, if you went back a couple of years everyone hated cone filters but now ther accepted/ its just choice guys

andzz

 

Give me your address I'll send you my Bailey DV26 which is correct for your car. Still sounds stupid though....

 

i like d/v's i had mine before the damn movies came out, mine came from grahame goode along with a monster 57i, at just a tad under a grand. Sounds like a bomb hitting the street when i change gear, and I fookin love it. Dont think the OAP's like too much but who cares. It is def a love it or hate it thing, philsaph4x4 (my boss) stripped his off when he got his cossie. I'm no 16 year old either, so its not an age group thing in my case, i just love the sound.

 

aint nothin wrong with dv's u miserable old baxtered's!

 

yea there is! thats the point!

 

better sound like a bus then like a dolfin......

 

you payed nearly a grand for a dump valve and 57i? i knew GG was expensive but DAMN!!!!

 

They must have seen her coming. Did they suck air in through their teeth?

 

who's joke is that! lee hurst! i had an asthmatic i lost me house!
