Its obvious that this car could go faster, i'm sure some owners will try and modify their 16/4's. With 1000hp already even a small is gain measured in hundreds of horsepower. but hey as always you can garuntee that the power figures are conservative. u could reprogram the ECU to make maximum torque it can rather than that restricted flat torque character. It wouldn't be so good to drive but it would realise another 10% power or more. Those turbos probably run 10psi and I bet thats only 80% of the design maximum, this is also would corrospond to the kind of margin of strength the bottom end of the engine would have (although good modern materials can be pushed past 100% increase in loading for short periods of time). So perhaps 1200-1300hp is the real limit of this engine, any more than that you'd need to upgrade parts or expect a very short lifespan of both the car and perhaps yourself <IMG SRC="http://www.supercars.net/servlets/cMsg/html/emoticons/smile.gif"> thoughts anyone?
