2011 STI Lays down 495whp & Runs 10 Second 1/4 Mile with COBB 20g!

Subarus have never been considered an ideal drag racing platform.  They are heavy, come equipped with relatively inefficient drivetrains, and have a coefficient of drag equal to that of a Dodge Durango.  That said, in recent years we have watched power numbers climb and 1/4 mile times plummet.  Why?  Ingenuity.  Although it is a small niche within...
