Advertising HP
Can someone please enlighten me about how a manufacturer
arrives at their "advertised" HP?
Why do they state a typical C5 at 350HP when every post of
a dyno reveals a stock number of ~330HP?
A conversation with a "cellmate" this morning resulted in
some confusion. He said that laws require that manufacturers had
to state "net" (I assumed BHP) and that engine or flywheel HP
was misleading.
A little help please...George

Net HP with all the accessories on the motor. Years ago it was gross with no fans, alternators, or power steering. Most measure HP here to the rear wheels RWHP so you lose 15-20% depending on who you talk to here. It's lost from driveline friction. and 6 speed or auto. Auto loses more.
