You should be OK at Goodwood as Mclaren run corporate days there for our American friendsAnyone know how loud 12c with standard exhaust is please ? I have a chance to take it to the Goodwood track and I believe the stationary 3/4 throttle limit is 98db .
When are you going i live about 30 miles away i may drop in to watch.Anyone know how loud 12c with standard exhaust is please ? I have a chance to take it to the Goodwood track and I believe the stationary 3/4 throttle limit is 98db .
I was one of the Bedford culprits and what you say it correct. I let off the power on the long straight but still was going fast enough not to worry about not maxing MP4's ability. Makes no difference turning the active Sports/Track on off for outside noise. BTW Mine was with the sports exhaust.I asked Bedford Autodrome guys and got this reply, I'm guessing it was standard exhausts:
"We have had two McLaren MP4-12C on track days they measure around 102.4db on static (fail).
On drive by as long as all sports buttons etc are left turned off and dependent of driving style they measure around the 84 to 86db range, so are good to go but they do have to be driven with the noise issue taken into account."
McLaren Birmingham told me this from back in the day
"Sports Exhaust is 102db stationary at 3750 rpm
Drive by 73.7db but it doesn’t say in what circumstance on the certificate of conformity"
Guessing that the 73db figure for drive by with a sports exhaust must have been in 7th at >2000rpm![]()
Bedford are a paranoid lot with noise, only track I have been tested at the gate before entering, they were turning cars away that failed no arguments. What do the locals think they will hear if you buy a house near a race track/ airport. Don't know what it is about the active buttons but London said you needed Track/Track to pass at C CombeI was one of the Bedford culprits and what you say it correct.

Standard exhaust passes 92db sound check at Laguna Seca even if you accelerate hard out of turn 5 past the sound check booth. You should be golden at Goodwood with a 98db limit.I have the sport exhaust and ran at Laguna Seca (92dB) all day without getting kicked off. Just know where the sound check is and lift just before hand
If it's a pre-track check, best of luck!
Thanks for the info. will do Laguna soon with no worries.Standard exhaust passes 92db sound check at Laguna Seca even if you accelerate hard out of turn 5 past the sound check booth. You should be golden at Goodwood with a 98db limit.
