The 66-year-old victim began what appeared to be a normal exhibition run on Saturday afternoon at the Thunder Mountain Raceway, east of Kelowna.
But the race car shot through the timers at 218 kilometres per hour and continued to accelerate past the end of the eighth-mile (201 metre) drag strip, slamming into rocks and becoming airborne before shearing off some trees and rolling several times.
Witnesses say there appeared to be no effort to stop the car and the driver did not deploy the parachute used by dragsters to slow down after high speed runs.
Firefighters and paramedics pulled the victim out of the wreckage and he was airlifted to hospital in Kelowna but died a short time later.
RCMP and the coroner are now investigating. (CKIZ)
