I have read about sub 10% losses for NASCAR... any truth to it, Che70velle?

The Porsches all (almost all) have transaxles, which I think helps a little. I know my engine builder, who only deals in LS stuff always tells Corvette owners to factor out roughly 12 percent from their chassis dyno numbers, as compared to 15 percent for F-bodies. (all of that is to guestimate SAE net numbers)
Now, I'm also curious, are we trying to compare engine dyno numbers with no accessories to chassis dyno numbers?
