German-based American-car tuner Geiger has worked its magic on the Hummer H3. A supercharger is a prime ingredient in Geiger’s tuning kit, boosting output on the H3′s 3.5-liter five-cylinder to 325 horsepower and bumping torque to 320 pound-feet. Top speed climbs to 130 mph, while 0-60-mph acceleration is trimmed to less than 8.4 seconds.
