i have heared of people who dont run dump valves on theyre cossies, is this true, wont this ruin the turbo?

liam

 

the general rule i beleive is......under 25psi and or a t4 turbo they arnt needed

sound a million times better without anyway

no it wont ruin the turbo.

 

If the Turbo has a weak part, then it will appear if running without a dv.

 

I run without one, no problems. Sounds sweet also

 

Leave the standard recirculating one on, don't fit a atmospheric type as they make the car sound too chavey.

 

no take the standard off so it chatters

 

will this b ok on a frs mk1?

 

do all cossie have this recirclating dv and where is it i have 4x4 saff tho

 

Yes, all Cosworths have it oe. It`s on your hot side of ic, a black plastic Bosch type

 

Best not to the FRS mk1 doesnt respond well to atmospheric DV's or no DV's (stalling bad idle & over fuelling etc)
Most people fit a forge 007P as an upgrade to the standard bosh recirculating DV, and an open cone filter if you want a woosh noise,

 

i hate the sound of dump valves myself. I have never fitted one to any of my turbocharged cars. My cousin had one on his rs turbo and it uesd to get on my nerves what a fookin racket.

 

Iv got a TIAL BOV on my 3dr and im very happy with it as its not loud and i all so get some chatter from the turbo

 

i run no D/V on mine at 27 psi, no problem.

sounds sweet............

ok guys no dv it is, i agree with the sound too, just wanted to make sure that it wouldnt ruin the turbo

 

I dont have one and its been running fine for 2 years at 32psi. Sounds awesome to
