windowlicker: I believe you are correct, I think it was Benny Parsons who had the challenge. It may be even more surprising to hear, but some teams have been recorded in the high 10 second range in practices. 10.8′s and 10.9′s are not unheard of. Teams will slow down during races though, to ensure lugnuts are tight and to cut down on mistakes. I do think though, that teams consistently being in the low 12′s or high 11′s is very realistic.

Who was the announcer who 3 or 4 years ago offered money to any pit crew who could bust a sub 13 second, four tire pit stop during a race? Was it Benny? I can’t remember.

A subsequent and related post with more detail of a training program would be appreciated by this (relatively new) reader.

Thanks for what you and Journo do.
