Calculating HP at the crank

LafitteZ

yea nissan is getting an average number, probably inflating it a tad and throwing it out there. The best way to tell is on a stock manual is about 12 to 15 percent drivetrain loss. Now wheels, tires, pulleys etc make it change thats why only car manufactures use that number because your average joe will never truly know unless they pull the engine and put it on an engine dyno which I dont think I know one person whos done that.
