You need to stop driving it while it is this rich it really bad for a new engine

More correctly - driving is fine, flooring it, so it goes this rich is not good at all.

It only changes from 14.7 when the car is cold or i give it serious throttle and come on boost, which as I'm coming to the end of running it in has not been the norm!

Also after looking at Ross's graph his afr drops to 11.5 under boost (unless I've misread!), so I figure it can't be that uncommon.

[Ross]

You need to borrow an air compressor and bring it down, or alternately I'll have to try and bring one up if I can find one. As has been said, stick to some 14.7 AFR cruising! Try and keep it >11, so pretty much off boost by the sound of it, at least you have gauges!

[prj]

Well, the AFR number you are seeing is a ratio.
So 9:1 is a whole lot richer than you think.

11.5 is perfectly fine, dipping below 11 is not, 9 is crazy rich and not good for the engine at all.
So yes, driving it around is perfectly fine, just don't beat it around until the boost issue has been fixed

[Sonic]

I only see <11 when i use near-enough WOT, even at ~1 bar it's ~11.0 AFR, and i haven't been driving around with WOT.. infact first time was tonight and 9.6 is the lowest i've seen on this 1 occasion.

Now that she's run-in i'll happily leave her on the driveway until i know i can get this sorted, especially if im going to cause damage driving it

And there was me thinking this fore-play was only going to last for a week.

******!

If i get this thing will it do the trick? http://www.amazon.co.uk/dp/B001EX2UJ...1EX2UJG5294738

Actually even a hand pump would do the trick...
One guy pumping like crazy and other one spraying soapy water.

Foam-party at mine this weekend then, plenty of pumping and soapy water

Have you ever tried that? I tried it with a footpump when I first got my S2, talk about hard work Oh, and it didn't even work!

[s2_bo]

I have tied a foot pump too but found that if you do have a leak there is no way you can build that much pressure, especially if the turbo seals leak a bit too..

The only way i got it to work was with a compressor. You could use a spare tyre if you have or make a female > female hose. Make sure you top it up first with a portable compressor to 50psi or so so that it has enough air in there to fill the pipes.

I have, but if there is a big leak it does not work.
Does not sound like Sonic has a very big leak though, so that's why I think it might work, if you are pumping like a mofo

[Ross]

I have a 12V charger, although it's not as quick as a foot pump and furious pumper it doesn't ever let up, and may be enough. Either that or I borrow one as offered. Will speak to you about that offline...
