Ethanol (e85)

- e85 setups will make the same power as the e60 setups. 

These are just estimates and I put a 30-40 whp window on each setup because every car has a different combination of parts, different location, different elevation, different temperature, different gas and very car experiences what's known in the engineering world as tolerance stacking.  Each component on the vehicle is allowed to be within a certain tolerance.  IE, the piston diameters are allowed to be between value a and value b, compressor wheel on the turbo is allowed to be between c and d, the turbine wheel between e and f, the rods between g and h, etc.  Some cars will end up with a combination of all favorable tolerances, some will end up with average, some will end up will all poor, and a few will end up with the golden combo.  Also remember that things like wheels and tires play a big role because they are rotating mass.  For example, a stage 2 car with heavy 18 inch wheels and tires will make less power than a stage 2 car with lightweight wheels and tires.  Same goes for brake rotors, clutches, flywheels and driveshafts.
