specs: The engine, based on the direct-injection 5.0-liter V-8 that serves in the LS 600hL, was codeveloped by Yamaha; it's upgraded with new high-flow heads, hollow cams, a head-scavenge oil pump (to help maintain even lubrication during high-g loads), titanium intake valves, a dual-inlet air intake (the second intake opens at 3600 rpm for enhanced high-rpm breathing), and other performance goodies. The net result is 416 horsepower at 6600 rpm and 371 pound-feet of torque at 5200.
