The first sentence of his original post states the RWHP numbers.

Why is this so difficult for people to understand? LOL

That's why the very next line of my post said:

I just ignore the titles, click on the thread, and view the information within.
I still think it would make more sense to just post RWHP numbers on an enthusiast site though and skip the flywheel guesstimating game.

We had a blast with this one, the engineers got paid well today as a result of these claims. Its been determined that the CTS-V coupe has the least amount of parasitic drag than any vehicle GM has manufactured to date. One nice platform with unlimited potential. Great job LMR!

I personally would prefer all vehicles get quoted at wheel hp, but they do not. I get over it, and accept that crank HP is the basis of comparison. You should too!
Fully agree. With car guys we talk whp. With everyone else you talk bhp, because they can't comprehend whp. No car company advertised whp, so the average joe doesn't get it. On another note, whp is different from dyno to dyno, so it doesn't mean much either without something to compare it to. At least the OP did mention the whp gain over stock.

So now to stir another can of worms: The factory 556bhp car put down 512whp? That's only a 44hp loss. Is the car underrated, is the drive train just that efficient, or does the dyno read a bit high?

We figured it was more like this. " 110 RWHP over stock" landed 612 rwhp -110rwhp = 502 rwhp. GM advetised 556 bhp. Difference of 54 bhp. 10.8% drive losses.

Most of the automatic trans V's are putting down 465-480 rwhp, the manuals are 485-500 many times. Bone stock. The automatics are quicker though, as they are more aggressively geared and the 6-spd auto shifts very nicely. The auto also reduces wheelhop, and you stay in boost during those shifts.
