332 bhp (brake horsepower) is made at the crank (engine output). Once you transfer that power through the transmission and the drive shaft you're looking at an average loss of 15% hp.
So when people talk about 280 or 300 hp they're talking about rwhp (rear wheel horsepower) The power that actually gets to the pavement and moves the car. With a 15% loss, the 370Z puts out 282.2 rwhp
No worries about the n00b question, the only reason I know is because I asked once.
Advertised horsepower is always brake horsepower.
