when u rev the engine u get a hard clonking and knocking kinda nise as u accelerate or rev the car through the gears.

it is definetely not pinking or detting, this sound is a clonky sound which gets louder as the u rev harder or as the revs go go higher while u drive. Whatever it is the noise sounds clonky but spinning, so as u go faster the clonky noise gets faster and a little louder, however when u let it idle or don't bring the turbo in so poodle about under 3k, u don't get the noise from the engine.

cheers
