Found another 14 bhp - total 291/295 PS in a c900!
Discussion
Just got an email from Klaas van Vuure at Beek Auto Racing - finally they found time to rolling road tune Saabine (Project 900T-R) after they put in the new Sweedspeed cams that'd been kicking around since late last year. Result: 291 bhp (217 kW or 295 PS-DIN in Euro money) @ 6,000 rpm, torque slightly down (thank God, the last thing I wanted was even more wheelspin in the lower gears and strain on the poor old gearbox) at 339.something lbs/ft (460 Nm) @ 3,500 rpm. This is exactly what I was hoping for, a gentle flattening of the torque curve with a bit extra fireworks towards the top end. Tractability should be that little better now. 
I tapped in the numbers at the Dyno Plot website, and this is the resulting graph: www.dyno-plot.co.uk/dyno/dynoplot/id%3D312%26sort%3Dpow%26but_sea%3Dqs%26frcd%3D41/Saab-900-Turbo-Sweedspeed-RacingBeek-Auto-Racing.htm
At barely 1,200 kgs, you can bet this skip on wheels is a bit of a flyer...

Blimey! Good work, fella!
Have you got one of the early 5 speeds, or a 4 speed or a post 91 5 speed?
Worry about mine and it's running stock power!
When I have a bit of time over the summer I'm going to play with my APC a bit to see if I can free up a few horses. Planning on just turning up the boost a bit to start with on my spare APC and then 900aero'ing it.
Waiting until we move and I have room for a second car in case I blow the 900 up

Post-'91 5-speed. It's got the short #6 primary gearing and it's a Neo Brothers rebuilt box
! Still it has stayed in one piece running 281 hp for over 7,000 miles and three trackdays so far... 
Well, to their credit it actually was a post-'91 box (albeit the #45614 from an NA/lpt) where the local rebuilders didn't specify a 'box type so it'd basically be pot luck as to what you'd get, it was rebuilt (although not to a high standard - noisy at certain road speeds probably due to pinion/ring clearnces not being re-set properly, quietened down somewhat now, and slow-witted synchro on 5th gear) and cheaper than what the one scrappy that had a post '91 box of unknown mileage and condition on the shelf...
