brake horse power is a term derived from "horse power" (the pulling power of a horse)

When a car has 220 horse power it is deemed to have the power of 220 horses.

so i used this ref. instead of CPU power, (I likened the analagy of a fast car to a fast computer) , hence

I hope you have a lot of BHP (brake horse power) under the hood of your computer...

(as clear as mud now )
