Finally, Dyno results of my 953!
@ 0.85 Bar = 339.5 rwhp, 52.25 kgm 
I spent 3 hours on the dyno trying to perfect the AFratio but just can't seem to keep it constant at 12ish. When above 4000rpm, AFR runs between 13.2 to 11.5... back and forth.
Unfortunately, there's not enough time for another pull @ 1 bar. After the dyno, I took the car out and did some street tuning for 1 Bar and that makes a hell lot more power!!!
I will be heading back to the dyno next week. Btw, I think I've accidentally messed up the fuel maps, while trying to record dual maps for different boost levels on the Mafterburner. Help needed on this one, please see my other thread. Tks!

8V
he wasnt running much boost at all on the dyno (read .85bar). Thats not too shabby imo, but im sure he can make a decent amount more with better tuning and, of course, more boost
Andrew, what turbo are you running?

Yes, its an 8V (CR around 9:1). Actually, I am quite happy with the results thus far(0.85 Bar), the car is making a good amount of torque with little lag, full boost @ ~3300rpm (4th).
ECUdooberhead, its a Kokeln Stage V (club) Turbo.
When I tried to hit it at 1Bar, there's a huge difference. Its amazing how 0.15 Bar more of boost felt so different.

Yeah, thats a big turbo, when running only .85 bar, the turbo isnt even running efficiently yet! It was the same with my Vitesse Stage 2, going from 14.5psi to 17-18, the differece was phenomenal.

ECUdooberhead, 52.25 kg should be around 370 lbs, I think.
tazman, 1 bar at most or perhaps 1.1bar scramble boost for say 5 seconds. Its a street car, reliability is crucial.
J Chen, I'll call you.
Silverbullet951, I don't know how much on upgrades alone. But if you were to include cost of car, paint, cosmetics, mods, rebuilt and rebuilts, labour and time etc... it all comes to about 60K.

Very nice Songzzz! Got a chart? It would be interesting to see how the torque curve looks like, it usally takes quite a steep dive on most 8v 3.0 liter 951-engines.
