The petrol powered Leyland can churn out 600 horsepower - 800hp if it uses nitrous oxide as fuel, she said.

Chanika was one of two women in the event along with Nicole Maandonks, of Reporoa.
Tractor pulling is more about power than speed, said event organiser Art Maandonks.
Mr Maandonks was again undefeated in the sport class driving 'Brutus', a former DT 466 International straight six tractor which uses a Scania truck turbo to add 500 horsepower.
Brutus pulled around five tonne over 100m with ease - beating off close rival Roger Allen, of Palmerston North, driving 'Henry Ford.'
Reporoa farmer Devril Thomas ran a close third with his 'Lil Devil' tractor.
The day-long event, which has replaced the annual Reporoa Sport Day, attracted around 650 people from the district and Rotorua.
Funds from the Reporoa Young Farmers event were donated to BayTrust rescue helicopter.
