advice needed can i fit a blitz car dump valve on 200tdi

hi all i have a 200tdi engine in my rangie bobtail. i am have the turbo up rated to stage2. now i know i need a dump valve to get rid off excess build up of pressure. but do i need a certain 1 or can i just make fit agood blitz one from a car.

You can't fit a dump valve to a car with no throttle valve. It is bloody pointless.

Ignore wammers, he's a grumpy fecker.

You need to completely strip the turbo first and take the head off...its a lot of work but well worth it. Please post pics as i intend to follow your progress carefully.

i got a friend who is doing the work on the turbo by putting a bigger impeller in to give more pressure into the cylinders .he said it will go like stink. but he said i need to put a dump valve on as if i dident the pressure would just build up and then bend the conrods if it cant blow off . so have not done this b4 but im always willing to try new ideas.

May I be so bold as to ask the reason for you attempting to build an explosive device?

Are you on ****ing drugs son??

numpty….

Go twin turbo then watch the ****er fly!

ive always wanted to get more power. so my friend who builds turbos suggested this to me.he said normally you would bore out the bores to suck more volumes of air in but this way by up grading the torbo you push more air in which is a cheaper and not so much work to do to achieve good results. he has done afew on thease engines and the ones who he did it for could not beleave the great improvement. so at the moment i am revamping the rangie and have the engine out at mo to do some modifications to it.

your mate has a lot to learn.....could start by how the internal combustion engine works and its varying forms.

trial and error is the way forward if the result is good and works i will let you all know the out come. will load a video of it on here when its done if i dont blow the ****er up.

He may build them, but sounds like he is not to up on the tuning or of designing them.

If you want to tune a Turboed Diesel, the rangie diesel is not the one to go for, beyond a remap and a larger intercooler, there is little else that can be done...

A larger impeller will do little to enhance performance - basic Thermodynamics will prove that.

just asking the question then saint v8 my m8 has a large intercooler now would this make much diffrence as ive always thought they were a waste of time.

Take the intercooler off completely, reduces weight and drag.

Cooler air is more dense, therefore there is more energy in it to burn.

A Turbocharger heats the charge air quite considerably and the intercooler cools it down and makes it more dense and better to burn whilst maintaining the pressure (the higher the pressure the more dense the air for a given volume) so with a larger more efficent intercooler, you will have charge air at pressue AND be cooler and therefore more dense and as such when it burns will be more energetic, giving you increased performance.

A larger impeller will not increase the charge pressue, only the amount it can compress in one go, but given the volume within the system is set, this oversized impeller will spin slower (due to the inertia within it, and also due to the back pressure created by trying to force more air into a fixed volume - think of an air compressor slowing down when the pressure increases), this will cause a restriction in the exhaust, causing a back pressure in the cylinders, reducing the efficency of the engine further, unless you increase the inlet port size to handle the increased charge air volume....

Everything in Thermodynamics is a balancing act across the equation...increase one thing, and you have to balance that out somewhere else....

A larger intercooler will assist in cooling the charge air and increasing density...a bigger turbo will do little.

I would say run 2 Intercoolers, just to be on the safe side, and for more power go for a HKS BOV rather than a BLITZ job. I hear they electric supercharger thingys are meant to be really good as well, so if you can get a couple of them in line of the intake the old M51 should be making close to 700bhp on standard boost. Good Luck

What about ram air? That works well

And water injection for the amount of boost you're going to be running you'll need that!

Intercoolers? You need charge coolers! Much more efficient
