Miles per Gallon?
I think, it doesn't matter what engine combo you're running. A 600hp engine is going to use as much gas as a 600hp engine.
Whether it's a turbo-charged 6 cylinder Porsche or a 6.2L LS3. The only real difference will be in the drivetrain, aerodynamics, & weight of the vehicle.
So lets say I have a twin-turbo V6 in a 2002 Firebird, and a built LS3 in an identical car. Both making 600hp. My thinking is the difference in gas mileage would be minimal. Is that right?
Power isnt really a factor in determining gas mileage. Its efficiency
