Noise on take off
I have replaced the engine in my 2006 Mazdaspeed
6, on take off I hear a sound like when growing up
we would clothes pin a piece of card board to the
front fork of a bicycle to get engine sound. The
speed increases with speed. After reaching a
certain its not heard---probably covered by wind
noise. The noise comes from the front of the
somewhere around the engine. Does anyone have
an idea what it is? Thanks.
