Surely the car was pretty heavily modified no? Approximating a 15% drivetrain loss 286whp comes out to ~336bhp which is nearly 100 more brake horsepower than these cars are rated to have. No car is that overrated from the factory so I deduced it has been modded. To my knowledge, the aftermarket for 3g/4g eclipses is pretty limited because it is overshadowed by its much better older platform (1g and 2g T/E/Ls), so I was wondering what kind of mods it had to achieve these kinds of results.
