Personally, if I really wanted to do Knockhill and they had a particularly strict noise limit that was different to the norm, then yes, I'd make arrangements to go there and get it checked (luckily they don't appear to have noise Nazi's installed by the local council). I've driven to Goodwood and been checked there before now (and failed) as have I at Castle Combe. All MSV circuits offer the test.It is not a surprise from your responses to see that you are in Bedford! hehe. Having to arrange a day to go down and have the noise test done is completely inpractical for most people. And would probably cost more than they paid of the trackday to drive down just to do a test in terms of losing a day and fuel. Would you arrange a day off to go up to Oulton Park or Croft just for a noise test? A crazy idea isn't it?
It is a problem if the car breaches the noise limit, no matter who is driving it. It still has to be accounted for with the local council. Evo have been kicked off numerous times when they've tried to set a time there. If the car fails the test during a prior driveby noise test, it hasn't cost you anything (other than your time and fuel to get there). If you fail a driveby on your first lap on a trackday, it's cost you whatever you paid for that trackday (plus your time and fuel). So unless my maths and logic are totally screwed, they are totally different scenarios.The other problem I have with the "test" and/or a Marshall doing is that it's no different to the owner doing it on the first session! Ie; why is it not a problem for a marshall to break the limit but a complete disaster if the owner does it? Either way the limit has been breached? that can't be undone, whether it's on a "test" or the first session of a trackday. It makes no sense at all to me.
Indeed there are. Your money, your choice. The real attraction of Bedford is the fact it's by far the safest, most spacious venue with a decent surface in the country. Luckily for me, it's 10 minutes away and always used to be great fun for an evening session on one of the smaller circuits. Unluckily for me, I'm now too loud and can't use it with any degree of assurance that I'll pass the driveby limits.In any case, there are much much better circuits out there (especially all the other MSV circuits) - Bedford is only slightly above an airfield venue IMO.
