Took the "P900" to Castle Combe last Saturday for the Eurofest action day. Had two sessions out on track, first was at the "base boost" that the car had been running since we had it. The second later on in the day, I took the waste gate hose off to see if the car would boost until fuel cut out - which it did.
An excellent day out with the rest of the UKSaabs bunch just hope some of them got some pics of the car in action on track!
EDIT>> pic of car on track thanks to Graeme.
