Description
The CP Evolution series is a fully developed version of the traditional Polini CP carburettor: to exploit the positive effects of a big carburettor (more power, more torque, more power) Polini uses a clever trick. The carburettor passage opens again after the slide valve to a much bigger diameter (CP24 = 26mm). This way the Polini CP carburettor with 24 mm of passage gives more power like a Dell’Orto PHBL25 carburettor. Thanks to the small dimensions and the integrated intake manifold, the CP carburettor is ideal on all powerful engines where a small size is an advantage.
