Goodwood Noise Limits
Has anyone had any experience of running a BEC on a Goodwood trackday? I seem to recall hearing from various people (Mark Chandler?) that the drive by
noise limit can be an issue.
I'm contemplating booking a day for next year but would like to work out if I'll be under the noise limits first. My car will comfortably
be under 100dB static as measured at a number of MSE days (usually around 96dB), but I haven't been anywhere with driveby monitoring yet. So,
from others experiences, what is the likelihood of passing either a 'quiet' (96dB drive by) or a 'noisy' (101dB drive by) day?
Clearly the usual caveat that everyone's car is different, weather conditions etc. are accepted, just trying to get a rough gauge...

A BEC will struggle, simple as that. Noise meters are on the outside of the circuit at Madgewick, exit of St Mary's and the inside on the exit
of the Chicane.

I never got as far as the driveby, induction noise killed me off on the static so now the exhaust exits out the back not the side 
At £400 entry it was an expensive day, luckily I towed with an XK8 so we used that instead.

I sprint at Goodwood but I would never think to do a trackday...noise limit is so low.

As far as I can see from the Goodwood calendar, the sprint events are a Cat 2 event with the (105dB static, 101 drive by) higher limit. There seem to
be a number of trackdays that fall under this category. Whether it would be enough though...

Didn't you get chucked out for noise even on a sprint there, Jeff?

Just a warning another place with stringent noise control is Bedford Autodrome , I know by the black flag I was shown, I run a BEC zx9r with the
exhaust on the nearside:

Bedford is indeed tight as well, my car just gets through there with an extra muffler so you need to be prepared.
What I should have added with Goodwood, they only allow a limited number of cars on track so you spend a fair amount of time queuing then get a few
laps before being pulled off, I think it was around 5 laps when I went.
It is a good experience, however £ per minute is pretty poor IMHO, better off at brands with the hills.

Aren't the noisy days even fewer cars as well.

I think at some point we have all fallen foul of the dreaded noise meters at goodwood

I did, I ended up fitting another silencer out the back of the car for this very reason. Side exit exhausts will tend to pass the static but fail the
drive by.

Thinking that I might need to rethink this plan then. I have the opportunity, through my father, to get involved with a marque specific club's
day there that would be quite appealing cost wise.
As an aside, what's Snetterton like with regard to drive by limits?
