Air noise in 3rd and 5th gear
 

Hi all I have an 2001 uk300 bugeye Running 340bhp
im almost getting what I can describe as an air hissing noise in 3rd and 5th gear it’s not there in 2nd and as soon as I go into 3rd even with the clutch still down the noise starts then goes in 4th and comes back in 5th. The noise in coming from the front of the car, the best way I could describe the noise is like the window is down a little bit and air Is getting in
Has anyone experienced this same noise
thanks
