As you might expect, the STI used in the record run is far from stock. Not much technical info was provided, but Subaru claims the weaponized WRX STI packs 600 hp from a turbocharged 2.0-liter flat-four engine, not the 2.5-liter engine U.S.-spec STIs get. With a weight right around 2,590 pounds, and a top speed of 180 mph, the STI cracked the TT course in a scant 17:25, a far cry from the previous record of 19:26.

Jaw dropping. I want this simulator now!
