One current test motor has produced 450 hp and 510 ft-lbs of torque. For cost and reliability reasons, the final package will probably produce closer to 440 hp and 470 ft-lbs of torque. Once the engine package is fully emissions certified, it will probably also be available for the standard Caprice as well. On a technical side, a great deal of confusion seems to exist regarding braking systems and what will provide better braking. First we need to define better braking.
Many factors contribute to a good braking system.
Two of the most important are braking distances and resistance to brake fade. Both of these affect braking performance by providing a higher coefficient of friction resulting in higher braking forces. For the street, the problem is that sticky tires don't last long and most performance brake pads create more dust and noise than the OEM pads. For those of you willing to live with some compromise, the single most cost effective improvement is brake pads. A more costly way to improve braking distances is to increase the diameter of the brake rotor.
