"         Our turned some nice numbers at the wheels, peaking at just about 236 hp at 5500 rpm and 267 lb.-ft. around 4200 rpm at the wheels (factory claims 263 bhp at 5500 and 280 lb.-ft. of torque at 3000 at the crank). We were scratching our heads about the torque figure for a little bit as it was supposed to have reached peak torque 1200 rpm sooner. But because our MS3 has a top-mount intercooler, we suspect insufficient airflow to be the culprit (approximate road speed at 3000 rpm is about 47 mph in 4th gear). The under-hood air ducting becomes useless if the hood is up and road speed is 0 mph.   You can see where there is a significant downward slope in the powerband beginning at around 5600 rpm, which explains why it&amp;#039;s best to short-shift a stock MS3 for best performance. We&amp;#039;re hoping to see some improvements to the curve once we get all the necessary factory hardware upgrades in place. "^^<http://www.w3.org/2001/XMLSchema#string>
