Found one with the same camera. In GT5 the blowoff valve sound of the turbo in the cockpit view is too loud.
@Ethomaz: Try to do the same with a non-japanese car.
The sound is loud in the video due the sound system used or the record equipment... you need to hear yorself with a good quality sound system.
Watch this video.... it show to you how the sound of GT5 is with a good quality system... there are comparison with others videos in the internet... the guy rate the sound with stars.
And no Japanese cars.
The Gallardo LP560-4 and F40 sound is almost identical.
Edit - The guys used a SONY STR-K885 810RMS HOME THEATER for GT5 and a HDR-XR100 for record the videos.
