Turned to the chief scrutineer for V8 Supercars, Craig Hasted of Cragsted Race Engines to transform my eco L77 into a very high performance engine that delivers ultra efficiency:
Some build shots:
OEM+ look hides a max effort NA build - $1000 bolts, $800 studs, custom forged guts cranks same compression as a diesel... but optimised for pure alcohol. Power, torque, and fuel efficiency compares favourably vs supercharging.
370 rwkW / 824 Nm
Smooth idle @550 RPM
Better torque plateau than an LS9
