Man 145.1 is flying in a F-125. Even without the wing the best I have ever seen is about 133-135 but I have never been to Daytona were you really have the track to build up there.
I always wondered about the stories about 160mph but I remember Russell Jr a few years ago going 156 which I know is moving pretty good. Johnny West was hitting 143 at MIS a few weekends ago and the straight is not near the length of Daytona so the 143-144 must really be were they hit that aero wall. So it would be interesting for sure to see what Jeff’s kart does without it.
