What's the slowest car you've raced in the 1/4 ?

that's a good run for that. Guy here in town had a new 2017 3.6 with the 8 speed and he ran a 14.60 in the 1/4. That would be about a 9.40 in the 1/8.
A friend of mine ran his 2012 Hemi and only ran 9.10's at the same track, he was amazed that I was running close to his times, he wasn't pushing his very hard. I do have a K&N air filter but I doubt that it would make much of a difference.
