A dump valve on a diesel does no good at all. If you do want one however it can be expensive due to the way that a diesel engine has no vacuum as theres no throttle butterfly (not normally anyway). It has to be done by using two microswitches. One on the injector pump, on the throttle and another one on the dump valve to make it work. Im not sure how it all works but from what i can make out when you've been on full throttle and let off the switch is released form behind the throttle and works the dump valve. Like i say no expert on it but i think you could probably get a kit fitted for about £300.
There is a guy selling them on ebay mate.
Excellent value, looks cool and sounds terrific.
Fast & Furious.
The only snag is that it's hard to locate the throttle plate (that's the pressure the DV is meant to relieve, between the throttle plate and the compressor)
What engine have you got mate cos quite a lot of dervs have a vacume switch on the throttle so you can connect that to the dump valve so it opens at closed throttle.
You can normally get a vac feed from the brake servo (wont affect brakes at all)
Basically there is a micro switch on the throttle which tells a solenoid to open the feed from the brake servo which in turns opens the dump valve. Quite easy when see it all together and working.
www.thedervdoctor.co.uk has done loads of Peugoets 1.9dt and HDI's, he even fitted one the diesel land rover . The kits might be a bit pricey for no gains at all but the noise is to die for and well worth it
Lorries make the same sort of noise because its the pressure relief valve blowing off on the air drier after the compressor has built up pressure to about ten bar. nout to do with the turbo.Can also be heard when the clutch is let back up as the hydraulics are pnuematically assisted.
lmao For the cost of a Diesel DV you could put that in to some mods that will actually result in a hike in power, unfortunately if you go down this route and avoid the DDV you will be missing the opportunity to make yourself look like a total asshat tbpfh
Don't listen to them mate - they're all killjoys.
Jelous of your turbocharged hypermobile.
They don't want it to sound proud and virile. Just because it doesn't need a DV doesn't mean you shouldn't fit one, right? Like spoilers and bodykits.
Follow your heart.
