hi posting here to get a few more opinions.my frst is running 16PSI (hybrid t2) and was wondering if i'll have any problems with the dump valve removed? it's running about 230 bhp with usual stainless zorst and filter plus plenty of other bits.it just drives much better without plus i get the chattering

what dya reckon ?

 

if you have 360 bearings in the turbo then you could do without a dv otherwise with a dv.

 

dump valves are supposed to be good for turbo'd cars but if you dont like the noise get a recirculating type which doesnt give a whooooooooossshhh sound

 

they are supposed to be good but the one on mine wasn't very good, it was impossible to just cruise at about 70mph without it constantly hissing. the car drives so smooth without it. the turbo i have is from turbo technics and i'm pretty sure they use 360 degree bearings. i've heard that it can cause the compressor to shatter

has anybody had any trouble with this or does anyone constantly run an rs above 16psi with no trouble

obviously i don't want to break my car but when i want to give it stick there's a thought in the back of my head that say's EXPENSIVE DAMAGE

 

I have a Dump valve on my Stage 1 cossie, soon to be stage 3. ill be fitting the dump value when i go stage 3,

I do like the Chatter better then the DV sound,,,, but DV's are ment to reduce turbo lag on gear changes as it keep the turbo spinning.

Better to be safe then sorry !

With out a DV it can f$ck the blade up, as they (may) break ! ! !

I ran 30psi boost on my T34 on my 3door for at least 10,000 HARD miles with no dumpvalve and was no noticable damage or wear.

Real main reason for DVs in the first place was to muffle the chatter noise.

Then atmo ones started being sold to people who liked that noise.

Im going to run DVs on the GTR even tho i dont like the noise because the turbo is an enourmous one rated to 950bhp and will be running at least 30psi and i dont want to risk breaking it...

 

thanks for the advice

spoke to turbo technics and they reckon it should be fine
