can you really run a VF34/35 without a DV as i love that noise...

 

there was a guy that posted up a couple of weeks ago asking about how do u get that noise. dont think he found out. sound like the wrc cars very nice soundwonde r how it can be done

 

Mine does that
YouTube - no dump valve

 

Some turbos are strong enough to handle it, others aren't.

 

but can you run without one with VF34/35 ?

 

Just find out how much it is to rebuild your turbo first.

You'll do bearings very quickly running with no dump valve.

 

when i had my evo 6/7 its safe to run without one. so i was wondering is it okay to run it without on the vf34/35

 

From what i have gathered th VF series turbos are not strong enough to run without a dv and you will damage the compressor blades. On the other hand the TD05 will run no problem without a dv, as it is much more robust.

Banny

 

Whats the standard turbo on an 04 STi UK

 

TD05 16G

 

So get it done...

 

a 04 sti should have VF34/35

 

i run my vf34 without a bov for a while but my mapper told me to get 1 asap as the vf ain't strong enough

as above, the TD series should be


but on that , i do know quite a few that run vf without bovs , take your chances i suppose

 

so, if your car has been mapped with a vta valve
would you need an udate to the map or would you be able to take the valve off without doing anything to the map ??????

you guys have got me thinking of doing away with my hks ssq now

 

you'd need the map tweaking

 

My TD05 chatters on lower boost but up high the forge dump valve gives a nice tshhhh but I didnt know they were strong enough to take it without one!

 

dam, i thought as much

 

Do you not get a vaguely similar noise to that with a Cold Air Induction Kit using the OE Re-Circ BOV or Forge equivalent??

I absolutely love that sound though and its VERY tempting as the car is still under warranty!!

TD05 with restricted DV

shame vf cant handle it .

 

My old starlet GT turbo did that after I mounted the air filter straight off the turbo. Great sound

 

So which is it then

 

Def VF35

 

my dumpvalve has just lost its appeal

a friend of mine recently put a fmic kit onto his 94 l-plate ra. had a simple baileys bov on the car, and its a very similar chattery noise. he bloody loves it, although its not exactly the same as the above, you can tell.

depending how much i give my car, with my baileys bov, i get more of a whistling hssssshhh noise than a pssssh noise if you understand me.

 

So I am assuming that its not just as simple as plugging up the dump valve?

I've got an STI8 IC on my classic but still the OE TD04,decat, panel filter and ECUTEK mapping.

If I plug up my DV I take it I'll get the noise - but not for very long?

 

Get a noisy worn clutch release bearing, they make a similar sound!

 

this is my uncles engine bay now his car makes the same noise as the one on the video its had alot of work done to it but unsure what!! but he doesnt have a dv like on my car he has what ever is fitted to the ic pipe what is it? iv but blue arrows to it

 

looks like a HKS SSQV
