Man, you're an engineer, use your brain. The new revision to J1349 is what's causing the revised horsepower ratings. To achieve the certification, ratings must be repeatable to within 1% of the advertised numbers.
Don't you find it suspect that a car that just just had its numbers adjusted under the new system, which states that they must be repeatable to within 1%, dynoes at 197 "hub hp", which would put the actual crank hp at around 230hp?An even 200 was the planned horsepower rating, but the new SAE ratings system cut that number back to 197 hp at 7,800 rpm.
Last time I checked, 230hp is not within 1% of 197hp.
I take it you didn't read the comments.
