My lord Alex, they are going to take some getting used to after the other tyres! Have you consciously had to adjust your driving style!
OOOOH, the manifold is on!
Have you driven with it yet? If so any first impressions?
Leftfield question, have you ever tried running a secondary air feed to the ITG through the inner wing to front fog light?

The additional fuelling... I assume this is setup as a returnless system? can't see an FPR or return line?... how is the extra fuel provided as the TFSI's have an FPR built into the fuel filter IIRC... has the feed been tapped off that pre-HPFP?
<tuffty/>
Sensible approach... swirl pot might end up being the way forward... would potentially make the fuel system less complicated and you would be in control of it all... its something I have considered for mine tbh
<tuffty/>
Out of interest... what grade plugs are you using?
<tuffty/>
Reason I ask is I used to runs 8's and had cold start issues... changed to 7's and was good... I believe 7's are std on 8P S3's anyway

It makes you wonder how the hell the engine runs when you see that. I can't believe how bad it can get in so few years (given it's not the first time your engines been apart for attention).
VAG must have determined it was acceptable wear & tear to have signed the design off.
In how many thousand miles is that build up alex?
Makes you wonder if catch can actually helps much in these engines given the design (no cold start valve to wash fuel past the valves), and the re circulation of gases etc. Every little helps I guess.
Wonder if it's all TFSi engines or whether high performance turbo cars are any worse than others (that said, based on V8 engines probably not). Great pics and a real wake up call to high mileage owners of unloved cars.
Roughly 30 000 miles since the bottom end rebuild.
So hypothetically a car of 60k could well have buildup twice as bad! That's not good..
are you getting it all cleaned off again alex?
I'm guessing it's not cheap to clean up and that the head has to come off to do it?
That looks very good Alex, do AMD do it themselves or send it away?
Wow, there is like a bronze piece on top of the valve that was AWOL previously.
Amazing job, but it does make you wonder whether the pitted surface contributes to accelerated re-caking of the ports. I've seen a few Mk2 GTi and MK3 VR6 Golf engines being skimmed and ported / polished, and whilst it involved quite a bit of expense I do wonder if it would make it harder for the s**t to stick.
That said, should give you another 50k+ happy miles (fingers crossed)
Seems like a useful alternative, is it big money? That breather system is the devils work.
wouldnt the pressure int he head change... ive seen one fail at the damn workshop doing my build.
