I don't think there is a max time. This is the result from 2010
Passon Performance Stick Shift Class
W: Tyler Anderson ('91 Daytona) – 16.75, 83.17
R/U: Scott Bourrell, ('64 330) – 9.588, 142.09

Scott made up for the r/u the next year though

One of the great things about stick racing, there are so many variables that everyone has a shot

So, you're good to go
