no...SAE has a very strict regime...it's why the Japanese mfgs have a hard time meeting them and have to re-rate their cars...
SAE HP is rated at the flywheel w/accesories...power steering, alternator, etc.
I'm sure it makes the 480HP/430 lb-ft, but at the CRANK, NOT at the wheels
Nissan themselves has said it only makes 473 SAE and will need to be tweeked to be rated 480 SAE in the states...
