I am aware of the ZR1's top speed and its HP. My example wasn't specific to it, just as a general comparison.
The camaro in Hot rod magazine that your speaking of has had extensive wind tunnel testing and has a drag coefficient around .21 if memory serves. His camaro was built specificly for land speed racing. It is no way close to my camaro or probably anybody elses of that vintage, and is even well under the drag of a new corvette. I have spoken with the owner on a couple occasions. A stock camaro of my vintage can be up to almost double the drag of keiths Camaro although it may not look it. Although mine is not stock, it is not close to Keiths either. My car is also not as aerodynamic as a NASCAR so neither is a viable comparison.
BSFC's are only taken usually on the dyno under wide open conditions and are often over .5 to the .6 range on High power big block blower and turbo cars.
That being said, I would rather be proven wrong and have fuel left than be right and run out 2/3 of the way. The 45 gallon stays. lol
