There is a caveat, however. When the engine’s cold, the system lights off with a distinct and violent crack, so if there’s a cat nearby it will tend to be up a tree as fast as its claws will allow. The camshaft is a little too hairy for the blower application and it lopes with a vengeance. Through the Corsa it’s so palpable you can almost taste it.
