not too sure why, but i get the impression that you like carbon fibre 
hoping for pics of the rest tommorow
How come so long for mirrors?
needed another week .. but i had to have my car back this week

Ahhh, could you not get another pair of mirrors and leave the spare pair with them?
Then just ebay the standard ones when you have the carbon pair? Although that sounds like a ball ache now i've wrote it.
has crossed my mind .. But will just wait till septrmber Then just ebay the standard ones when you have the carbon pair? Although that sounds like a ball ache now i've wrote it.
when the roof gets done
dont know ye what went wrong..
all of a suden loud bang then she was hunting the revs
with no drive , and sounded like she was sucking in air ..
also burning fuel like mad..
hopfuly something silly sent her to monkfish last night so will know more by lunch time was to what is wrong.
fingers crossed nothing to bad.

Ok, heres the deal with the supercharger issue:
The intermediate supercharger driveshaft bearing originally failed.
This is an intersting arrangement as the bearing is not an interference fit on the shaft. It has a small opertaing clearance. But, because the shaft osscilates when running, this bearing gets hammered until it eventually siezes. the bearing race, which is now not moving then wears a grove in the bearing interface area of the shaft. Hence the noise.
Earlier versions did not have this bearing. It was added later. The problem only manifests itself on 122's with upgraded boost.
Given that replacing the driveshaft and intermediate bearing does not solve the problem as it will eventually re occur, we normally leave the bearing out, which also allows reuse of the driveshaft. This effectively returns it to the earlier arrangement.
However, on this occasion, for reasons that are not entirely clear, the shaft ossicilation appears to havebeen more extreme and worn through the tube which shrouds the driveshaft. This tube seperates the inside of the intake manifold from the outside world. Net result is very poor running due to unmetered air entering the engine, and loud noise which was the driveshaft rubbing the tube.
So, on this occasion, it looks like rewmoving the intermediate bearing may not have been the right thing to do. So it will be reassembled as new with a new driveshaft and intermediate bearing. Given the circumstances, we will only be charging for the driveshaft which would have been required had we done this first time around.
