Doesn't change the fact that they ARE NOT UNDER ANY CIRCUMSTANCE achieving <9% driveline loss. Sorry bud, just ain't happening.
Since we're talking mustangs... you may actually want to read some of these threads where graphs are posted. You'll find that other folks, often who have been doing this for quite some time, call the numbers posted into question.
^ Start reading.
Magnaflow had a hard time getting above 300rwhp with an exhaust change... on a 2010 (315bhp rating and a much better factory tune), etc.
Again, no one is arguing what a motor can or can't do, rather that the correction method you are implying (8% as "normal") simply isn't accurate. If a S197 mustang was rocking 280RWHP, she'd turn a far better time than a low 14 in the quarter. In reality, the S197 mustang puts down around the low 250hp mark (fordmuscle pulled the same number) which falls directly in line with it's power readings.
Dude you almost sound like you know what you were talking about, then you said...

Stock s197's run 13.5 all day and actually do put down 260-270rwhp. i get my numbers from real life where are you getting yours from, when have you ever seen a low 14 sec s197? lmao
p.s: that link you provided just confirmed everything i have said lol thanx
