i spoke to someone who has driven the DETCHA car extensively, and he told me that the estimated 13.0 was a joke...

something about that solstice...im guessing that the person who made that picture doesnt know much about cars or racing, as they seem especially impressed that it ran those times in 29 degree weather. cars love cold air...be it NA or turbo, the cool air improves performance...hot air hurts it...so that car might not run those numbers in 80 or 90 degreee weather.
