291 hp from a 240,000 km Saab 9-3 V6 Aero Hirsch – AutoWeek’s Dyno Test Revisited
In 2021, a Dutch father and son rolled a repaired 2005 Saab 9-3 Sport Estate into Beek Auto Racing's dyno cell. The car had front-end collision damage, a freshly replaced dashboard, and 240,000 km on the clock. The Hirsch tune on its 2.8 V6 was rated at 275 hp. The SuperFlow system measured 291 hp and 482 Nm - 82 Nm above the published torque spec. This is what that result tells us about the engine, the tune, and what these cars are still capable of.
