Cory Abbott says recent updates to the Mazda include a revised rear suspension set-up plus a new turbocharger with improved flow that has yielded a horsepower increase. The starting point for this week's 6.636secs run was a career-best 1.03secs launch increment to the 60-foot timing beams.
There are 20 teams entered in the Pro Compact class — rotary and four-cylinder cars — this weekend with the Abbott's RX-7 ranked among the quickest contenders.
The other New Zealander in action at the Jamboree is Auckland's Rod Harvey with his six-cylinder turbocharged Toyota Camry racing in the Factory Xtreme category.
At a Willowbank test earlier this month Harvey unleashed a new 5.708secs/256.08mph personal best run that consolidated his rankings as the third quickest and second fastest "import" drag racer in the world.
