Dans Turbo Build

[dan944]

As promised. Moved the IC a little and changed the pipe work today as wasn't happy with how it was sitting.
Pics to follow.

I'm no expert just curious, but shouldn't the exhaust hanger on the left be attached to the box and not the pipe. Is that going to stress the Flexi joint as it's supporting the weight of the box ?

[dan944]

Hmm. This seems valid. Makes sense. Possibly as it was too far and they've just used the one that was there and overlooked this.
Power flow have the lifetime warranty so I think that will be brought up if there's any deterioration at all.

Thanks for pointing that out though.

[Call the midlife!]

Here's one before the hangars got welded in. It's gonna have to do for now as forgot to take one of the finished product.

I didn't want to rain on your parade, but thought I would mention it. Like I say I have no exhaust fabricating knowledge so it could be perfectly acceptable for all I know.
I just think with that big can rattling around on the Flexi it might be an issue down the line. Lifetime guarantee though  at least it won't cost you if it needs repairing.

[dan944]

Thanks for noticing.  Only 12 month on the flexi though.
Wish this rain would bugger off!!

Might be worth asking the question now then.

[dan944]

So, I have finished everything I can do up until this point. I have some questions to clear things up.

Vac lines. Again!! 

I currently have:
Blue solenoid to vacuum block.
Block to gauge
Block to EMU
Block to pipe that comes from fuel cage and normally goes to charcoal canister (which now doesn't exist)

So looking at it today realised that's not correct can I have some help in correcting it please....again.

Shnazzle has his loom built so you shouldn't be long for your ecumaster black

[dan944]

We'll see :s

Depends if I can sort these bloody vac lines. Haha

You deleted the fuel vapor canister? Are you sure you want to do that? And if you have, have you put a 1-way valve on the line from the fuel tank to allow pressure to be released?

The vacuum for the VSV is a good place to tee into to get vacuum. Basically the opposite end of the VSV from the canister.

Have you left the PCV system as it is?


Added a pic. You can see the T off from the back of the VSV (top right of pic) and then another T bottom left for the boost controller. Instead of that, yours would go into the block. Much tidier

[dan944]

Deleting the canister was pretty much a must.
So I need a one way in the line from the tank to the solenoid. Correct? Because to me that makes sense.
Also there's a line from the solenoid to the TB by the looks of things. Is that correct?

[dan944]

[dan944]

I've put the one way valve in the pcv it otherwise it's standard.

I need a one way valve from the tank to the solenoid.

I've plumbed the solenoid to the vac block.

This made sense as it's taking the same route as the canister was but with the vac block In line.

Now I'm confused again.

Is there a way I can check if it's routed correctly? :/.

P.S. also do I need to block off the pipe from the TB to the solenoid or does the solenoid do that job?

[shnazzle]

Lots of confusion here methinks

PCV with check valve: good. Pcv should be OK low boost but why risk it right?

Now VSV...
Have you just removed the canister but you're still connecting the VSV to the pipe that goes to the fuel tank  unfiltered?

Interesting question on the need for a check valve. I suppose if we're not trusting the pcv,why would we trust the vsv to hold boost? Helen's car doesn't have a check valve on the vsv line from intake mani to vsv (it connects to the intake mani, not throttle body).
I guess yes, if you want to be 100% safe, add a small check but it may be overkill.

CV system has the pcv valve on the cover and connected to the intake mani, and a breather pipe from the back of the cover to the front of the throttle body. So blowby gasses are sucked up the crankcase by the intake manifold vacuum to be burned again and the "space" is replaced by metered air from the breather hose (top of throttle body), so the crankcase is never under pressure.

When the mani is under boost, the pcv stops pressure being built up in the crank case. The pcv isn't always  strong enough, so you add a check valve.

The turbo creates suction on the breather pipe, which creates a vacuum, but only to a certain point. At higher boost levels, it overcomes the vacuum of the turbo and blowby goes into your intake. Not good, so need a check there too.

[dan944]

So much confusion. I apologize but there is something about vac lines that fry my head.

Canister removed, then line from blue solenoid (vsv?) to vac block, vac block to tank, unfiltered. The other pipe on the solenoid I've left to the intake mani.

Then I have ecu and gauge also on the vac block.

Crank breather at the back has a filter on it and other end is blocked off.

Picked up a Bosch innovate wideband for £59.99. Better than the £99 at RRR

Which sensor Dan? Brand new?
LSU 4.2 or 4.9.
If 4.2 I would send it back or secondhand.

[dan944]

It's the 4.9, brand new. Comes under BMW sensor.

Got a picture?

[dan944]

[1979scotte]

Next question is the connector the same as the ECUmaster?

[dan944]

They use a Lsu 4.9 so can only assume it's correct. If it is wrong when I get there then I'll buy the one from RRR and return this one.
Part numbers match as far as I can see though.

[1979scotte]

It's all good then.
That's very cheap.
I wanted an IAT sensor from RRR started out at 25 ended up at 40 with vat and delivery.
Reminded me why I bought my Det3 elsewhere.

[dan944]

I'll get the IAT from them as it's only £30 as I'll be collecting. Also I got confused by the different types when I was looking to buy one so £30 I can deal with.
