Re: 2007 Mustang V6?
Mr. Southerland, your point of view is interesting for this discussion, and, I must also add, in the CLASS WEIGHT BREAKS section, the sentence (based on pounds per NHRA-factored horsepower) under this tittle, can also be taken as a part of the answer, though it doesn’t also explain the ESI specs situation.
But further in this same section, a part of it, said: The power to weight factor is the shipping weight of the vehicle divided by the advertised or when applicable, the factored horsepower for the OEM assembly line cylinder heads.I’m still questioning the meaning and also words like: “advertised” and part of sentence like “or when applicable” to explain my understanding of the rules.
Sorry for “this too long post and THANKS once again for this very good discussion and your precious help. I’m still learning…
Keep on Sir,
Charles Stewart
