Dave F Posted November 20, 2006 Share Posted November 20, 2006 I'm doing a trackday in a few weeks, and checking through the bumf they sent me it states that the noise level must not be more than 105db. I have an NA with a nur spec r with cats still in place does anybody know if this is likely to exceed the 105db. Cheers guys Link to comment Share on other sites More sharing options...
uk-rich Posted November 20, 2006 Share Posted November 20, 2006 think 105 is pretty generous Link to comment Share on other sites More sharing options...

Cheers guys I'd have thought you'd be okay, but do you have a bung you can take with you just in case? Link to comment Share on other sites More sharing options...
Dave F Posted November 20, 2006 Author Share Posted November 20, 2006 Yeah taking the bung just in case. I was hoping you were going to say yours was less than 105 but somehow I doubt it:) Link to comment Share on other sites More sharing options...
Pot Posted November 20, 2006 Share Posted November 20, 2006 In a slight slant off this (Sorry) - What's the limit on the road?... I've heard things from 105db @ 4,000rpm to 'Whatever the copper decides'... Is there a clear cut limit?... Link to comment Share on other sites More sharing options...
SimonB Posted November 20, 2006 Share Posted November 20, 2006 There is no fixed limit on the road - the law simply says it must not be "unsociably loud" or something like that so basically up to the police. I've never heard of anyone being sucessfully prosecuted for it though, although some people have paid a £30 fine I believe. Normally they would just issue a vehicle defect thingy I think so you'd just go to an MOT place and get them to say it was ok. You will definitely be less than 105db with the bung in (assuming it's measured the normal way at 3/4 revs at 1m or whatever) and I would think without it too.
