Performance Manifolds is the result of a lifelong passion for speed, precision, and performance. Founded by Managing Director Phillip Corbet, the company specialises in high-performance aftermarket intake manifolds for Holden V6 and V8 engines.
Our flagship CPR6 and CPR8 manifolds are the product of decades of hands-on mechanical experience, track-tested performance, and a relentless drive to push the limits of what’s possible.
The Man Behind the Manifolds
Phil’s journey into high-performance engines began in his father’s shed at the age of 15, where he built a street sedan from the ground up. By the time he earned his learner’s licence, he was already behind the wheel of a heavily modified Datsun 1600—fitted with nitrous oxide and producing 175 hp at the rear wheels.
As a third-year apprentice mechanic, Phil built an SR20-powered race car that showcased not only his mechanical talent but his engineering mind. The car featured a 16-valve alloy block, quad 48mm throttle bodies, a ported and flow-tested head (tested using his own Superflow110 bench), and custom cams, achieving 170 hp at the wheels, naturally aspirated.
In 1998, his dedication and performance were on full display at the Club Car Nationals at Eastern Creek, where he recorded the fastest qualifying time in the under 2.0l class with a 1:49.89 lap. He went on to finish 2nd in the national championship for two consecutive years -1997 and 1998.
A Legacy of Performance
Over the past 25+ years, Phil has been immersed in high-performance tuning, engine building, and motorsport. His deep mechanical understanding and racing pedigree have earned him a reputation for innovation and reliability—two values at the core of every manifold we produce.
