The manifold is the result of years of research and testing, multiple prototypes and ground-up redesign of the original groundbreaking “Corsa Veloce" product range.
High-end TIG welding assembly makes them suitable for up to 100psi boosted applications.
The plenum volume and runner length combination has been selected for aggressive low and mid-range torque while opening power higher in the rev range.
The plenum volume is large enough for serious gains but is still compatible with factory AC.
The Street version is suitable for any level of performance modification as they have conducted tests on completely stock engine/turbo/fuel system setups with approximately 9% gains in torque and power level, with the same percentage gain on highly modified setups running E85.
Designed for vehicles no longer running AC.
10% gains in both horsepower and torque on a stock engine
