BOV for Laura 1.9 PD

karan561 · 10th September 2009, 22:35

Had called up Ranjit ( AR Motorsports ) he says he has done a couple of installations of BOVs on 1.9 TDis ( Octavia ).

He is pretty confident about the istallation of the same on the Laura.
Will go and meet him personally over the weekend.

I am just hoping that it would be a BOLT ON job so that if any point of time i want it back to STOCK i can get it done with ease.

@Karan - Do let us know how things pan out, I have a 1.9 laura also, and would like some other work done and I am also in Mumbai.

What is your main reason behind the BOV? Because I don't think a BOV is really required.

For the sound...the bling!

Hi Karan,

I've got a GReddy Type RS BOV that I had got earlier this year. It is a universal fit..Let me know if you're interested.

I am not sure if it would fit a TDi motor. I strongly recommend that you do your research..

Cheers..

@karan-watch the work closely. I dont think a BOV is necessary or even possible on a diesel. If it works out, let me know. I'd like the bling too

Correct.
Someone answer this : Which car comes with a BOV from the factory?

vdiatech · 12th September 2009, 22:26

i am sure, lot of TC'd petrol cars come with OEM plastic BOV's to serve the actual purpose of a BOV. These may not be fancy and not used to amplify the wooosh sound. you may not even notice them

Also, I think a BOV is very useful in a turbo setup.

My twin turbo Nissan 300zx came with two "bov's" they are called re-circ valves. Ideally if a BOV is really required then the factory would provide it. A BOV may be required on a modified car, but on a stock car, not necessary.

At the end of the day. if you want a BOV get it, don't worry about requirements really.

A BOV, actually, is not very necessary. It's for the sound that usually people go ahead with installing it. Unless your motor is churning excessive power and boost, you don't need it. It just sounds really cool, when you come off the throttle!

Why don't you go through the Pete's website? There are a few project cars there and one of them is a Laura PD. I'm sure it has a few modifications and may even include a BOV.

AFAIK, the BOV releases the pressurised air that is trapped between the compressor of the turbo and the throttle which shut when the driver lifted off the accelerator. If not released quickly, this can damage the vanes of the turbo compressor. Diesels dont have a throttle.therefore, Only petrol turbos can have BOVs. Please note BOVs are different from wastegates, which are present on every turbo, diesel or petrol.

It just does not make sense to me.

The turbo is stock therefore there is no increase in boost, no other mods are made to the air intake system, the stock recirculation or bypass system works fine and there is no back pressure on the turbo unit. The BOV makes the car sound like a vintage steam engine and is loud enough to make a long drive a nerve wracking one.

Instead, I would suggest a pete's box, CAI, RD ECU or other useful mods which generate more useful power.

For cosmetics think of a spoiler, side skirts and other body kit. Perhaps even a custom 'bling' paint job.

Cheers,

Diesel motors have a DV. Petrol motors that are turbocharged have BOVs. There is a difference. Look it up.

Precisely!

People use diverter valves in petrols too.

There is a difference between a DV and a BOV. DVs are generally used on turbocharged, yet, stock cars. Correct me if I'm wrong?

my T'chd fiat coupe ( prev car ) had an oem plastic dump valve, i had replaced it with a shiny forge re-circ dump valve. it was petrol, factory turbo charged, 20v car
