Howdy Folks. I've never been real thrilled with the relatively low HP and Torque of the 4.6 as set up by Rover. I'm figuring that I will either rebuild mine at some point later this year or replace the motor. It has that annoying noise (sounds like a slipping sleeve) whenever the temp exceeds about 204 or so. Anyway... I got to reading and realized that TVR had put the engine in their Chimaera. And, they had improved the performance numbers to: 4.5 liter, 4,546cc, 285 bhp (213 kW; 289 PS) 310 lb·ft (420 N·m). Why can't we get the same performance ??? It would make a world of difference in the Disco....
