JACKSONVILLE, Fla. -- By day, Elaine Larsen runs her own motor sports company.
But she really lights it up when the sun sets.
"My nighttime job: I'm a jet dragster driver."
She's one of only four women who race these machines.
"This is kinda like a top fuel dragster on steroids," she said.
Put very simply, it's a car with a jet engine strapped to its back.
"Came out of a T-2 Buckeye, which is a fighter trainer," she said.
Her car's engine literally came out of a jet plane.
It can go from a standstill to 100 mph in one second.
"You pull 5Gs on the launch, so it throws you to the back of the seat."
She says the fastest she's ever gone in her quarter mile races is 336 mph.
And you can see her race this weekend at the Daytona Spring Turkey Run.
Among the classic cars and displays at the Daytona International Speedway, Larsen will be there showing off her jet dragsters.
