Porsche - 911 GT3
The 415-horsepower, 3.6-liter flat-Six engine produces a specific output of 115.3 horsepower-per-liter, among the highest of any naturally aspirated production car. The Boxer engine’s power peak is reached at 7,600 rpm, on the way to an 8,400 rpm redline -- 200 rpm beyond the previous GT3 model.
In addition to its high-revving characteristics, the GT3 engine’s performance has been fortified by careful attention to airflow rates. Changes to the variable intake system include a throttle valve enlarged from 76 to 82 millimeters, optimized cylinder heads, and a low-backpressure exhaust system.
