Based on my calculations from the 230/203 running on 5 cylinders, regardless of psi, if running on all 6 =
5 = 230
- ---
6 x
5x = 230*6
x = 230*6
-----
5
x = 276+hp!
I say the + because I'm sure running on 5 cylinders has some sort of effeciency loss associated with it OVER running on 6 cylinders. Not bad for a 2.5L SVT engine
