I am thinking about replacing the Dump Valve on MY97 STI TYPE R, has any one used or herd one of these so called loudest dump valves in the world (up to 150db), they are made by TurboXs abd are sold through
www.potn.com.

Sorry did noy mean to post twice

I heard they are meant to be loud! But do you really want to be like the ford boys

siwrx

theyre an australian company and are adjustable so good for idling problems, supposed to be stupidly loud.

I definatley dont want to be like the ford boys, but I want a different/original type of sound that will turn heads and impress

600bhp would impress. A loud dump valve IMO would not.

I thought about this but if you raise the volume I presume its by forcing the air through a restricted hole so the pressure must be higher inside I.e. its not doing its job properly releasing pressure quickly.

Surely you could connect it to a device that made a farting noise? Now THAT would turn heads....LOL

FASTER MIKE!!

well i`ve got one on my uk turbo and it sounds amazing supposed to be 120db@ 13psi. the reason that they are so loud is because of the big **** off trumpit on the end
have a look on turbo xs for more info.

so if you waqnt loud then RFL is the baby

mike

StickyMicky

omg
you bring the level of the impreza down to dirty stinking maxed up uno turbo levels when u fit crap like that

as the bloke above said
600 bhp would impress
makeing your car sound like its got a flat tyre does not
cheap tacky crap

It seems like I have started an argument here.... Thanks for the info I am still unsure what to get. Its a pity you cant get the wastegate chatter like the wrc cars!!

HKS one sounds good, well I like it. OH and it works well.

TyPe~~R

Hey Faster Mike do you think its actually too loud. Its a tricky question, but is it a pain going off all the time or just loud but good......if you know what I mean LOL

Turbo_Steve

Well...you could do what I did: get the HKS (it's loud and sounds cool) and fix it so it doesn't go off all the time.

This was achieved using a 2 port solenoid, a pressure switch and a normal switch for inside the car.

Connect the pressure switch to a vacuum line and set it for about 9psi. Then connect the in-car switch accross it to "override it" and force the dumpvalve on. Connect this in series with the solenoid. Then you have a system whereby you have NO dumpvalve at low boost, unless you flip a switch to get all the silly noises (or if you are driving in a way that will abuse the turbo....i.e. sudden throttle movements etc etc).
BUT in the event of high boost when your dumpvalve is "Switched off" the pressure switch will ensure the solenoid enables the vaccuum line and triggers the dumpvalve, protecting your precious turbine.

I only did this because I value the sleeper status of my car, and so tend to drive it mostly with the dumpvalve switched off.
In the event of a bit of "traffic light grand prix" with a ford/r5 GTTurbo or whatever, or if I am "driving spiritedly" I will switch it on, as it enhances my drving pleasure and gives the 'badge' boys something to gawp at.

It's all a taste issue. Everyone knows what an impreza is, so why pretend?

some well stuck up opinions on here eh?

FASTER MIKE!!

no i don`t think it`s too loud, but then i think it sounds good, as do most people that have heard it. as for the coments about bringing it down to the ford/gt turbo level they are just snobs
if you want the WRC chatter then leave the std dump valve on and get an induction kit as this makes a cherping sound

mike

TyPe~~R

I have the standard dumper and an apexi induction kit, but I get no sounds like that?

FASTER MIKE!!

mine did with a K&N kit on but it was`nt that loud well not turbo xs loud
