Trevor Duckworth took his motorised barstool on a soon-to-be confirmed world-best record speed of 22.465 mph.
A number of new Guinness World Records speeds were also set at the event for a wheelie bin, electric mono-wheel and wheelbarrow.
Guinness World Record adjudicators were present on May 16 and 17 at a Straightliners land speed event at Elvington Airfield, North Yorkshire
Prospective barstool record-older Trevor is the founder of Straightliners - which organises some of the most unusual automotive speed events.
Mr Duckworth holds 21 world and over 30 British records over all distances, riding solo motorcycles and three wheelers.
He has designed and built numerous unusual vehicles including world's fastest toilet.
Mark Foster set a world record speed of 59.057mph in an electric monowheel.
Meanwhile Andy Jennings set the wheelie bin world record with a speed of 45mph.
The 28-year-old design engineer said he loves building and breaking stuff in his personal time and has always been into cars.
Andy attempted the record for a school friend who was injured at work five years ago.
Comatose for two years - he was left with brain damage and unfortunately passed away during lockdown.
"The reason for doing it is to raise awareness that anything can happen to you," he said. "One life, live it!"
Kevin Nicks broke a record in his motorised wheelbarrow with a speed of 46.19 mph.
Built from scratch from donated or existing parts - Kevin wanted to encourage people to use DIY projects to focus their mind on something positive in these difficult times.
