yes theorettically the car is pushing around 240-250 hp that is what the motor is developing, producing. multiply 217 by around 15%.
15% is due to drive train loss, how much hp is lost from engine to the wheels, ie. transmission, cv axels, brakes, tire size. so if the car is producing 217hp at the wheels, what it uses to accelerate.
217hp, multiply an extra 15% and you get 249.55 so about 250hp that the engine produces.
32.55 is the amount of hp lost in the drive train.
do the same for tq. 185whp x 15% comes out to be 212.75tq. does that make since?
27.75 is drive train loss
the numbers provided on the dynosheet is whp, not engine horse power (flywheel hp). those are two seperate things. gm's 205hp and 200tq are engine horsepower. so both numbers are underated significantly.
so the real numbers that gm should be saying are approximatly
249.55hp and 212.75tq. make since?
