I am looking to book a ‘quiet’ 98db day at Donington and with TWO baffles fitted to my 600 I measure 100.9 at Brands static (IIRC Brands test at 45 deg/1 metre @7000rpm,)
Does anyone have any experience of how this might compare with Donington’s drive by testing? Revs & track position will obviously affect the reading too.
Many thanks
