Turbo Diesel & Blow Off Valve... Help! - Turbo Blow-off valve  

astro boy

diesel boost is quite abit different to petrol, mainly because there is no throttle body.

unsure as to why you would want a bov when it'e not needed?

there is a way to do it but it will give you aids

^^^What he said

Eehan

I merely want to do it, as I've customized the exhaust for a deeper sound, and I can hear the turbo in the background, I'd like to accentuation the sound of the turbo...

The bloke at Auto1 said that because Diesel doesn't have vacuum, that it wouldn't work as well, but I can wield something into the intercooler to get it working..

Google.

^^^^ this is pretty much it really as there is no butterfly to close then its not needed at all, throttle is controlled by the fuel pump so 0no damaging pressure is applied to anything on throttle shutoff, wont actually change the sound of any thing, you could try a screamer pipe for your wastegate if that made you happy.will accentuate the wastegate noise . .but added cost for no particular gain, other than noise.

I've been googling, and I can't seem to find anything on the web except from here, on how to install a BOV into a TD...

I know a few people have stated in earlier thoughts about installing one, and it's quiet and all, I have just never done this sort of stuff and want to play around/experiment...

I've been looking up on a dose pipe? What is that? I want to try and get the noise of my turbo spooling to be heard, as it is currently non existent.

Get a real engine, real turbo, real exhaust and you will hear it.

Christ mine is mostly standard but you'd think it was about to suck up cats off the sidewalk.

Stop trying to make your 4x4 into a pigeon/ricer, shits so fucking gay.

Go look how a turbo petrol engine works.

Then go look at how a turbo diesel engine works.

Now come back and tell me how the fuck you think it could possibly work.

Eehan

OR MJ80, You can piss off this topic if you haven't got anything nice to say... Great, cheers buddy... Much appreciated.
TwinCam16- Read my initial post, I was merely asking if it is easy and/or possible...

MJ80

I told you exactly what to do, champ, take your ignorant attitude and follow your own advice.

If you only want to hear the turbo spooling then up your boost. Simple. That will make it sound alot louder. I listen to factory Mitsubishi's with loud sounding turbo's. I can hear them no worries at all and that it factory everything, not even 10 Kilometers on the clock.

Also anything is possible with the right amount of money. If you want to hear a blow off valve then get a petrol car, If you want to keep the diesel engine and 4x4 then accept the fact that there is no point to a "show off valve" because there is no need to vent the pressure and there is no snapping close throttle body butterfly.

noremac82

put a screamer pipe on, every @#$! will hear you then.

waste of time and is a heap of wank. aids is sicker then your idea.

just download some blow off valve noises and play them in your cd player next time your feeling hectic

and next time click search. cause each week there is a different pole smoker that gets the unique idea of a blow off valve on their diesel vehicle.

Thanks everyone for your thoughts, I have decided to NOT go ahead with this, this was the purpose of the thread, thank you.

Mosus

blow off valve as stated would be pointless and stupid.
What exhaust system is on it?? i ran a 2.5 straight threw system on my 2.8 TD hilux no mufflers and you had all the turbo noise you wanted

asher

Good to see someone who actualy knows what they are talking about!!! Mosus is dead right. If you want turbo noise, it is very simple, NO MUFFLERS. Manufactureres try to stop this noise as most people don't want it, or appreciate it. I think you will be very happy with the increased turbo whistle you can hear from the system described by mosus. If you want the whistle you hear when you pass a turbo diesel truck up a hill, this is what you need. There is not a big difference in exhaust note, just alot more turbo whistle. If you don't believe us take out the piece of exhaust that attatches directly after engine pipe, ie. before the mufflers. I am sure this will deliver the turbo noise you are after. By the way speaking from experience not speculation, just like Mosus is.
On a turbo diesel the turbo muffles the engine noise, the mufflers muffle the turbo noise, I am sure you will be happy with a system like Mosus runs...

Blow off value on the colorado 180rwhp with a blow off value fitted not bad david

Explain how this was done and what pipes were tapped and where the throttle body is.

colin832

I would laugh so much if the guy who has done this to his turbo diesel has just wacked the bov on the pipe from the cooler and then tapped it to a vac source.

Fitting it doesn't mean it will work.

It's possible on the surf/4runners/hilux around the early 90's. I've seen some guides on how to do it, involves welding a little pipe between the turbo and the intake. I believe those engines may have a throttle butterfly, or if not, have something similar.

I'm still learning about turbo diesel so forgive me if that's wrong... but I did go looking for info about this a couple of weeks ago (purely for shits and giggles).
