Reply to "Engine performance"

Can't help putting my engineer hat on sometimes.  I have been skeptical of the drivetrain power loss figures -- 50 to 75 hp, 20%, or whatever is often times claimed.  Say you have a 350 hp engine and lose 20% for 280 rwhp.  That is 70 hp loss.  Each hp is approximately 750 watts.  That is 52.5 kilowatts of power loss.  Maybe the short duration of a dyno pull is the saving grace here.
