Running without a DV- benefits other than noise..?
As title really..
I know a few have done it, NS04 in particular, as he runs a VF35 as do I, which iirc is up to running without a DV..?
I'd only consider doing it if there was a performance advantage from doing so, so that's the question, is there..?
Cheers guys..

As chris says, downs sides apart from potentially recking the turbo are..?
Finally, to temp try it out, if I made a blanking plate to bolt between IC and DV would that be ok. As my boost gauge is tee'd off the DV I presume that wouldn't work, but just for an easy try out of no DV would that do..?
Now where's me tinsnips..?

The only thing I'm not sure about (and I'm yet to look at it properly) is what about the small ~5mm vacuum?/boost hose that comes off the DV, which my boost gauge is tee'd into..? Is that also bunged, if so where do I plumb my gauge to..?

Of course, doh..!
I'm definitely going to give this a try, are there any implications with regards to fuel maps etc..?
I take it they do sound quite 'interesting' running without one..?

It was fine, I never took any notice of noise etc. I only ran it for a few thousand miles then added a dump valve purely due to the fact I thought the car should have one ??? I think I notice the noise more now. Always reminds me of the "3 stooges" as its a sort of "woo woo woo" noise

What's the theory behind blanking off the DV?
As a BOV is used just for sound...and to make your car run rough
The Recirc makes the car run smooth.
Blanked off.....theory?

Just running the oe inlet, but tbh I'm doing it for the performance first.. Still I wouldn't mind hearing any vids/sound clips that might be knocking to see what I might expect, lol..
Those bungs look like nice bits of kit. Lol, I used plastic pluming bungs when I did the VTA, but they only come in 22mm max. The DV outlet pipe is ~32mm iirc..?
Thanks for the info Danny..

Sounds like the 'squirrel mincer', the P2 test on Top Gear

Hmmm, just given it a go and it sounds like someone smothering a duck.. Not loud, but that's down to the oe air inlet pipework/resonator etc...
Car does feel sharper on full bore gearchanges, but the thing that I'm a bit concerned about is my defi is now showing a peak of 1.7bar, 0.1bar above usual peak..! KL is silent. Could this be a 'false' reading, as all I've done to test out removing the DV is pop a plate between IC and DV, leaving all other pipework as it was- ie DV 5mm hose still attached to inlet manifold with gauge tee'd off..?

if you dont run the car with a dv i presume your using the standard dv as wont this cause alot of stress on the turbine shaft due to the exhaust wanting it to spin one way and the backpressure from the throttle body been closed wanting it to spin the other ???
