Yeah, that list of numbers was generated by an individual who looked at the Factory Service Manual, but then went and added some more. The 13.5 is about the fastest that a stock car ever went in the 1/4, probably a zero reaction run. A more realistic number is 14.0.

Coefficient of drag is .29 for the 93 rx7. I believe the newer JDMs had .3249 or something like that.
