S3 PE1820 big turbo build

[Welly]

Sounds like you're thinking about reliability here! lol

Can you blame me, really?

 

[Welly]

Happy days, we're through the MOT after my bodge on the headlights to bring the level up.... :thumbsup:

Videos to follow soon.... hehehe

 

[Speedy Steve]

Glad to see it pass mate know get it out on the road and have some fun!

 

[scoobyra]

Is it done now then Welly? I can bring the black car up and we can see how it goes compared to yours.......until my vf34 goes bang again! lol

Yeah mate, all done as far as I can tell. Fingers crossed anyway... lol.

I drove it down to Weston Super Mare yesterday with the missus and the nipper. No problems on the way down or back. The DIS was claiming ~45 MPG on the motorway using cruise control at 80.

Yeah right. However I did do 100 miles to about 3/8s of a tank of fuel, so in all fairness that's not that bad.

Went out hunting last night, however didn't come across anything worth racing. Booo.

Good work! Who needs an RS Audi

P.s what's your 0-60 , estimated or previous K04 hybrid?

Not sure yet mate, I need to get it out of an evening to do this really....

I seem to have developed a misfire on peak boost - annoying.... lol

Changing spark plugs today, they have got a little hot so that's the first thing on the list to change.

Welcome back to S3 ownership... lol.

 

[Westy]

Good news mate. :sign_welcome: back

Wouldn't be right owning an S3 without a missfire lol

 

[Welly]

LOL, annoyingly true.

It will most likely be plugs or that damn coil wiring again. I might just bite the bullet and buy the repair kit....

 

[DaveA3]

put ur engine in a tt

I'll probably pop over to Bill's later on, so swing by

 

[Welly]

Yeah, I may well do. I wanted to get there yesterday but couldn't due to family issues.

I'll see you there about 8.30ish.

 

[Dane]

Safe as houses.

 

[Welly]

Safe as houses.

LOL, depends which houses.... turned out some ones by the Severn in 2007 weren't all that safe!!

 

[Dane]

Lol - your up a hill, your house!

 

[Welly]

Lol - your up a hill, your house!

lol.... don't I ****** know it, towing the S3 off my drive en route to Bill's was a nightmare...

 

[Welly]

OK, went out and bought some plugs yesterday. Got home, fitted them, took Bumble out again. Missing.

Boooooooooooooooo.

Checked the coil wiring, no problems there either.

Gave up with that temporarily and decided to find the fuel smell that I was getting in the cabin instead. I knew that the number 4 injector seat was damp.

Turns out that the misfire and the leak were the same problem.

The bolt for the fuel rail has stripped a few rows of thread inside the inlet manifold (A symptom I am starting to see around my engine bay now after the thousand times it's been apart) and had worked itself loose. Under boost it was just allowing air to escape.

Longer bolt installed, fuel smell gone, and misfire fixed.... Happy days.

 

[Westy]

Nice work mate. Stripped threads and snapped bolts are my worse nightmare.

 

[Welly]

Honestly mate, any aluminium thread that is in my engine by is now showing signs of having a hiding. Sadly, they don't last forever.

I had a very close call with my main rear suspension bolts. Got both of them cross threaded at one point but managed to rescue them and get them in straight

 

[Welly]

Well, it's been a week of driving it around everywhere now since the MOT.

A few small issues have crept up, but nothing massive, and they were all easily resolved.

Will be changing a few things this weekend for the better one hopes....

I am moving up to the next size WMI Nozzle. I currently run a DO5 nozzle, which is 5 gallons per hour. I will be moving this up to the next size, which oddly is a DO7 (7 GPH). They simply don't make a DO6.

This turbo is shifting 280+ G/S of air, and I think that the WMI is now less effective than it was based on this.

Will fit and see when Bill has time to sling it on the dyno, as when it was poorly, fuelling was added and timing taken out temporarily.

Also, I currently vent my PCV to atmosphere. My main breathing point is the stub out of the cam cover, and that then vents to the back of the engine bay.

The problem is that I get the smell of oil vapour in the cabin and it is very annoying I must admit.

Planning to formulate a new plan and reconfigure this so that it vents in a more controlled manner. Not sure how yet....

 

[Sandip]

Not sure if it'll work Welly but what if you plumbed the breather into the charcoal canistor and then vented it from there to atmosphere?

Not sure if what will work dude?

 

[Sandip]

Might have a bash it myself since my charcoal canistor is sat in the garage collecting dust lol

Your not running you charcoal canistor are you??

 

[Alex C]

Not sure if what will work dude?

having your PCV vent to the charcoal canistor

 

[Sandip]

having your PCV vent to the charcoal canistor

Sorry Welly, this is what i meant lol

 

[Welly]

Sorry Welly, this is what i meant lol

Ahhhhh right, no, I'm not sure how that would work long term, and also mine isn't even there any more.

I've decided I will leave as is, however vent the pipe further underneath the car. The problem is currently that the pipe isn't that long, and the gasses are just coming back up into the engine bay.

 

[Dani_B19]

I need to vent mine bettet, that smell is rank in hot weather lol.

 

[Welly]

Yeah, I've noticed it more since it's been warmer I must admit, interesting you say that.

 

[superkarl]

I've moved my breather filter right to the front of the bay right next to the battery, reduced smell alot. If i put the bonnet seal strip back on i get nothing, until I open my window.

Tuffty said exactly that about the rubber strip, BUT it's a trade off unfortunately.

Keeps the engine nice and cool and under bonnet temps right down without the rubber strip.

I have just bought a metre of 19mm ID hose, which should be enough for me to cable tie it down either at the front/bottom of the block, or at the back of the subframe.

 

[Welly]

From what I have read, reconnecting the vac feed under the inlet manifold through the one way valve should draw the gasses from the PCV into the inlet manifold on idle.... Obviously due to the vac feed from the mani pulling the gasses in.

Interesting.....

Sadly, this won't work without reconnecting the TIP.

The downside of it being a closed loop system is that it's either all or nothing.

 

[superkarl]

Yeh I still have the strip removed regardless of smell. It really is an improvement having it at the front behind the grill, the air flow effectively diluting the fumes. I can imagine having it really low will eliminate any smell. My only concern is mine as it is has oil on the filter, must be fumes condensing, so having it hanging down will probably drip.

 

[mk1chopper]

Do you still have an air box? or are you running a cone filter with the box removed? could you vent it near the filter so effectivly drawing the smell back in to the engine?

Sort of semi defeats the object of doing it though. Oil vapour reduces octane....

I'm considering running the pipe straight down through the old CAI for the stock airbox (The hole in the NSF side of the bay). That would get it out of the way, remove smell I would think, and also vapour would be diluted by passing air...

Sooooo many options

 

[Speedy Steve]

Mines started to smell more. mind that could be down to the warmer weather and actually driving it lol. Think ill move my filter down near the front suspension some where

It would seem then that the warmer weather does makes stinky issues worse....... That's one to bear in mind in future...

 

[Speedy Steve]

yep especially with the rubber strip removed!
