3 inches off the Corkscrew at 100 mph.
This one comes from The Freep via J.F. Mursial's tumblr, a good pedigree.
A video shot by Jason Bell at Laguna Seca, practice laps in a 125 shifter kart.
From Jason's video description
"A lap around Laguna Seca Raceway during the first car/kart open track day with ncracing.org on 11/1/2010. Top speed here with a bit over 100mph. More can be had in the draft.
The kart is a 2003 Birel CR32SR, with a ~32hp, 125cc Honda Stock Moto engine (CR125), 6 speed sequential transmission. If ran with SKUSA, it would fall into the S4 Masters (Age 30+) category. 405lbs minimum weight, including kart, driver and fuel. Tires used are MG-FZ. I use 110 octane fuel and Maxima Castor oil along with Motul transmission fluid.
I borrowed this camera from a friend, so I was not sure what the optimum settings should be for this application. I know it was set to 720p, 30fps and the mic gain was about 15. The camera was mounted on top of the radiator."
Clip is after the jump...
