Thank you jhardy1 and sibeen for your response. The formula is a UK one for their HARE vehicle. That's why it is so different from what normally is seen.
I never took into consideration what MathCAD does to the revolutions and rad/s. It has been some time since I had to do any calculations...
Forgot to add file.

I cannot figure out why MathCAD 14 is out putting the wrong answer.
I am doing a simple Power calculation using the formula:
P = BMEP * V.s * N/2 where
N = 4400rpm = 73.333rev/s
V.s = 2L = .002m^3
BMEP = 22bar = 2200000Pa
The correct answer is 161.3kW and MathCAD is giving 1014kW.
