^^^ Hence the quotes around "standard" when I used 12% to do the math. Its not perfect, its an used estimate. If he put down 221 and the cars in your area average 181 that's a 40 hp gain which is only 2.7% off of the estimate I came up with. That's not to shabby for a guess. Also, when you had torque, you add hp. hp = (tq x rpm)/5252.
