Does SAE standards not stipulate dyno tests to measure advertised HP. Putting a truck in drive and flooring it up a hill does not measure peak HP. I remember being passed by a gasoline powered pickup pulling a big fifth wheel while going up a long steep grade with my Powerstroke. When the truck pulled out to pass me I already had my foot to the floor. I knew my engine was only making about 200 HP at the rpm it was running at and if had wanted to race I would have to manually shift the transmission to a lower gear. I had nothing to prove and didn't bother racing, my point is that peak HP is at 2900 rpm on the Powerstroke and the transmission shift points are not programmed for racing.
