@sickburnbro ITS KINDA DIFFICULT TO SCAVENGE MORE ENERGY OUT OF COMBUSTION, PERIOD
RN THE ONLY THING GOING FOR US IS BRAKING A TURBO WITH A GENERATOR AND FEEDING THAT ELECTRICITY INTO A HYBRID POWERTRAIN
SO WE'RE SCAVENGING FROM EXHAUST
AND THAT PLUS 4T ICE THAT WE'RE MAYBE RUNNING LEAN AND MAYBE RUNNING ON A MILLER CYCLE WITH VARIABLE VALVES -- CAN GET US INTO HIGH 40% RANGE OF THERMAL EFFICIENCY
