hey all

before i bought my rs i asked the chap to refit the dump valve as i wanted to see what it was like to drive with one on. I have been searching up here and there and i quite fancy the idea of just normal "chatter" as i get a lot of pissed off looks from people when driving out of work or into town as most old people seem to literally s**t themselves when im driving towards them! Some people have said taking the dump valve off will reduce the lifespan of the turbo etc but is this true?

also what is everyones opinion on dump valves or chatter? comment away

[THEHOG~]

i am not really sure on the differnce.

i am not all that on this loud hiss sound.
but i would have it on to help my turbo.

but i love this sound

would be better on a higher powered car i supose.

I have been running mine at 30psi for a year now with as much 'chatter' as i can get and its still going strong...

I prefer chatter, loved the way mine sounded. But really wanted the original airbox fitted, which no longer makes any noise. So refitted the dump valve on mine.

[wildheart]

Dump valves arent needed on a T2 so wil be no problem at all.

[slaney21]

ok cheers guys

just need to get a new pipe now then

They do sell individual hoses

[slaney21]

o god lots of hoses everywhere!!! dont know where to start

[JamieFRST]

Just phone and speak to them they are very helpfull.

[slaney21]

ok bud will do. cheers

i love the chatter noise but it does brake the turbo eventually cause its turbo stall where the air goes back through the turbo. but yea chatter is better than dump valve lol im having chatter! for a little while anyway

[dangerousdave]

mine makes this noise with the dump valve installed!! i thought something was wrong as it was hissing out the breather pot when i first started it up!! .... til i noticed the dump valve was locked shut

It doesn't break the turbo.

[landanimal]

i have been told by a few people who have had a 200sx that it does eventually and if it dioesnt its not good for the turbo i have never seen a turbo broken from it but i have been told.

Chatter Rules............ Dump valves are for Gays.....

Simples......

Yes it does

[Harris]

my car is 19years old with the original T2 with 112k miles and its been chattering for most of its life and it hasnt broken.It doesnt even smoke or use oil and runs 13psi happily. Many things can contribute to a turbo breaking.

The idea of a dump valve is to basically release pressure that returns to the turbo when you come off boost without a dump valve this pressure, excess air whatever you want to call it returns to the turbo and over time should in theory damage it. Although you may be lucky and it might not. I would always say I love the sound of a chattering car but I just spent £400 odd on mine so I would prefer to know its gona last longer and have a dump valve... I've got a universal induction kit on my car to and that makes its own gorgeous little woooshing noise, its brilliant my mum hates it.....PERFECT! lol

[M1K3Y_B]

Its all about the Chatter

[Fezzy Turbo]

Okay lets clear this up......

Yes there is a back pressure that pushes back on the blades of any turbo. The dump valve will release this and give you the sounds. Now this back pressure is there with ALL turbo's but the most "at risk" turbos are your high pressure turbo's. With a T2 it is small, compact and shouldnt really be pushed past 12psi (standard turbo), thus making the turbine blades at "less risk" of back pressure breaking of the turbine blades.
The "chatter" (nothing to do with wastegate chatter) or flutter is the blades of the turbo "stalling" or slowing down, the same as a helicopters blades make a noise. You hear this very well on a FRST when you add an induction kit, as there are no restrictions from the turbo to airfilter, unlike an ERST and the airbox doesnt get to muffle the noise.

This has been a public information announcement for FT.com, by some old Scottish guy

[Ruishy1]

Cant beat the sound of turbo stall

m old Si turbo running 14 psi made a great noise with the induction kit

[essexmarc29]

i built my 2i turbo just for chatter .people said to me,stick an mfi lump in for 200bhp.but no i stuck to efi.got chatter and 200bhp ,well roughly lol

[Max M4X WW]

I do like the whole chatter kills turbo's thing.

But standard car's do it - You just cant hear it usually.

[filtra]

Neither - both are look at me, I have a turbo.

Heavily insulated airbox or recirc DV.

i dont do it for the attention, i just love the whooshing and whirring nosies only a boosted car can supply

cant wait to get my mr2 fitted with the chargecooler and get the boost up to 16 psi

[RS Joe]

:) ok cheers guys

just need to get a new pipe now then

You can also just get an alloy blanking plug, incase you decided to refit it later.
But Imo... Chatter is the only way to go!

[slaney21]

ok so just to clarify,

will having a t2 without a dump valve kill it over time then a t2 with a dump valve??

i want to keep the dump valve on mine but want a slightly quieter one

[RS Joe]

It should do no harm at all... Otherwise Ford would have fitted them to the cars themselves.

[noel1982]

Right i'm going to add to this subject all modren cars are fitted with recuirculating valves to stop the damage on the turbo escorts use a twin piston valve ie DV26 or DV36 fiestas only need a single piston valve ie DV24 or DV34 my 76000 mile FRST had damage to the blades when i bought it so vince @ cr turbos done a great job and brought the turbo back to life My advice always have your valve on

Thats because modern cars have bigger turbo's than the old T2 a FRST has. And after 154,000 miles my T2 has zero damage, zero leaks and is quietly gathering dust in my lock-up

[crazycage]

i run a dump valve on my fezz but i run a gt28 and wouldn't want to risk the damage as there not cheap
