Default Calculating HP at the crank

Im just curious about whether there is any reason why this method isn't accurate.


Let's say you do a baseline dyno and get 270 at the wheels. The crank hp that Nissan claims for the Z is 332. So that means the crankhp/whp ratio for your car is 332/270 = 1.23

Then after all your mods let's say you dyno at 310.

Would it then be accurate to assume your new crank hp is 310x1.23 = 381.3 ?
