The Forced Induction VR6 thread

The novelty soon wears off :lol:

 

I don't even notice mine half the time, your brain kind of tunes it out.

My recirc valve is passing air on idle, which would screw idling up. It also sounds like a dump valve anyway. :)

Therefore I would say tread very carefully with any kind of dump valve!

I'm terrible for it, I even make the little "schew" sound when I change gear in my girlfriends 1.4 pug 306, just to wind her up :)

Thanks for that, I think I'll give Forge a ring to check how it runs with a VF kit

I just had a recirc on mine when I had the Rotrex and it was loud like a dump valve! It sounded fcuking awesome, I miss my Rotrex :( The R32 sounds alright though I suppose, needs a turbo though! :lol:

The trouble is too many chavtastic weapons emit a gay little psssssshhhhhh, followed by a puff of blue smoke usually, which gives dump valves a bad name.

 

What you want is Darth Vader shouting RAAAAAAAAAAAHHHHH from under the bonnet, which only a socking great Tial 50mm can achieve :D

What you really want is a nice whooooooosh as the charger/turbo gives you boost to tell everyone you are booting it. All dump valves do is let everyone know you are changing gear. :lol: (and maybe stop your engine going bang)

I just love the sound of them when you feather the throttle through some corners and they're chirping away like mad, I blame it mainly on that old group B rally video link that someone posted up recently :)

 

Admittedly stuff like beaten up Fiat Coupe's dumping though the window of a mcdonalds drive-thru don't help, or rusty old Impreza wagon's gunning it past bus stops full of kids

[Kevin Bacon 5]

That chirping noise is compressed air travelling backwards over the compressor blades and isn't healthy for the turbo at all :D

 

A lot of people pay good money for that noise these days, but they don't realise the long term damage it's causing :lol:

Ah right maybe not then, maybe I'm getting a bit carried away with myself, my 8psi isn't exactly going to turn my VR6 into a Metro 6R4 :lol:

Another quick question, I've done a search but couldn't find anything...

 

I've had a look at the belts that came with my kit, I got two, apparently one is for A/C cars and a shorter one is for cars without A/C,

 

For a start they both look like the have 7 ribs, secondly they're ribbed both sides? Is this correct?

 

My mate has an OBD2 golf with a belt ribbed both sides, just concerned it will slip on the waterpump if I run it

[Kevin Bacon 5]

7DPK 1390 was the right belt IIRC, which was a standard VR6 AC belt.

 

1390 is the length in mm, 7 being the rib count, D being double sided and P and K = anyone's guess :D

 

It doesn't slip mate, don't worry about it.

 

The kit originally came with a Goodyear 6 rib single sided belt, which lasted all of 3 microseconds. The VAG belts last well.

Thanks Kev, wealth of knowledge as always

 

Nearly done with the installation then I can stop filling up your thread with my ramblings :)

[Kevin Bacon 5]

No worries, it's all related chat :D

Right everything is pretty much done, a million and one little bits I needed to collect, hoses, bungs, connectors etc

 

I'd just to know if anyone can recommend anything to clean the inside of the charger with before I bolt it on, it has been sitting around for a while and the chap I bought it off had lost the caps to stop any crap getting into it.

 

Carb cleaner? petrol? wd40 etc, or just give it a good blow through with an air hose?

[VR6Joni 0]

I'd give it a good blow through with an air hose, I wouldn't spray any thing in there as it has the potential to either build up Cr@p or harden the shaft seal which could lead to an oil leak down the line.

Cool thanks for that, exactly why I wanted to check first

Recirculating valve...

 

Little vacuum port at the top of it, run a hose to the abs vacuum feed like a Schrick (little green caps) or does it need a feed from somewhere else?

 

I've got it in my head to pop a Y piece into the line that comes off the FPR but I don't know why I'm thinking to do that :confused4: :D

 

Any ideas? Does it even need a vacuum feed, I've looked at pictures of engine bays for the past 30 mins but can't figure it out

Like this?

Like this?

 

That's where I've seen the picture, I knew I had it in my head for a reason :D

 

If I'm honest I accidentally deleted your very informative PM so I couldn't double check, Was that for the recirc valve then?

Yup!

Yup!

 

Coolio, Pretty much done then...

 

Test drive tonight :clap:

Awesome! You'll love it. :nuts:

Looks like the test drives tomorrow as some bits didn't turn up

 

Question though...Would I be an idiot to keep my Bonrath PR on? Forget the fact it's metal as I'd heat proof the underneath

 

I'm concerned I wouldn't be keeping the intake pipe 63mm all the way to the TB, would I be going to 76mm too soon and losing boost pressure or will it make little difference?

Did you not get a moulded plastic pipe with the kit that goes from charger to TB? I take it not...

I did but it's not in the best condition, been chopped and adapted a bit and I'm wary it may leak boost.

 

I would run the charger - silicon hose - metal t-piece with recirc valve - silicon hose 63mm-76mm - then my 76mm bonrath up to the TB with another silicon hose, should look and sound nice and probably flow better but I am aware I should try and keep it 63mm right up to the TB, is it that much of a difference though?
