Cayman The Destroyer!
4.0L M97, dry sump twin garret turbos, open exhaust, 100 octane gas. 700 + WHP at ~ 1.2 BAR. This engine has excellent throttle response a broad torque curve and outstanding power. The catch? For the multiple full throttle applications of road racing the heads lift enough that some combustion gasses leak into the coolant and over pressurize the system. For boost up to .8 bar it's great. We are going to retire this engine and install a 996 TT based 3.8 L in the Cayman race car.
