BSR are one of the Swedish aftermarket tuning companies that deal with Saabs (and many others).
They’ve released a tune for the Saab 9-5 V6 Aero and as part of their website documentation, they include their dyno results in both stock and tuned form.
The interesting part about this is that Saab quote the 9-5 Aero V6 as having 300hp and 400 Nm (295 lb ft) of torque. BSR’s dyno results tell a slightly different story.
The solid black line, to be measured by the axis on the left, is the standard power measurement. As you can see, it drifts well above the 300hp measurement.
The dotted black line – representing standard torque – also spends a reasonable amount of time above the 400Nm (295 lb ft) measurement.
The measurements BSR get for this engine in standard form are actually 317hp and 438Nm (323 lb ft) – a significant increase over the stated factory maxima.
Peter S, the guy who emailed me about this today, figures the following is the reason why:
My guess is that Saab indeed got the same induction and exhaust changes that the Insignia OPC received, but that the agreement with GM requires that the “official” numbers tilt in GM’s favor for some certain timeframe.
I don’t know any different and I assume BSR haven’t just cut n pasted the results from one car to the other. BSR’s test of the OPC definitely lends some support to the suggestion that Saab got the modifications, even if they can’t talk about it officially.
It’s good to see 9-5 buyers are possibly getting more for their money than they first figured, according to this Swedish test, at least.
