trackhound Posted January 6, 2009 Share Posted January 6, 2009 I notice that knockhill now have noise regulations on their website http://www.knockhill.com/trackdays/new.php I am going on the March track event and have a rather loud 3inch exhaust. Does anyone know if this applies to just bikes or cars too? Thanks Link to comment
paul555sti Posted January 6, 2009 Share Posted January 6, 2009 It mentions it on the hot marques page. So i would imagine its cars as well. http://www.knockhill.com/trackdays/hot-marques.php Link to comment
RS Grant Posted January 6, 2009 Share Posted January 6, 2009 105dB... sheecht, if they actually put this into practice then a few people might be getting black flagged. Never thought the sheep on the hills nearby were too fussed by the noise, obviously I was wrong. Cheers, Grant Link to comment
paul555sti Posted January 6, 2009 Share Posted January 6, 2009 At the tail end of last year i read a thread over on pistonheads where one of the guys with the black ultima's was kicked off. He did have crazy straight through pipes on that could be heard from miles away. Link to comment

He did have crazy straight through pipes on that could be heard from miles away. That's a bummer. I have a silencer plug but it is very restrictive and the car dets badly when I use it under boost due to the increased back pressure. I will need to measure the noise level somehow - does anyone know of any garages in central scotland that have the equipment? Link to comment
paul555sti Posted January 6, 2009 Share Posted January 6, 2009 One of the members on here has one, he posts as corsa. I am not sure if its the same standard as knockhills but he had it at the last central meet. Link to comment

col666 Posted January 7, 2009 Share Posted January 7, 2009 I got my old wagon tested by the Highland ****stabulary a few years ago and for reference it read 95db. Full magnex system, no cats. Had an RS turbo back in the day that was 104db! Link to comment
DR Motosport Posted January 7, 2009 Share Posted January 7, 2009 The noise regulation has been on Knockhills web-site since October. Track Scotland ran an event on November 1st, but the noise regulation wasn't used. Just as well really. At 5000 RPM and 0.5m at a 45deg angle (standard measuring) my track Impreza measures 107.8dba or 101.2 with the bung fitted. Link to comment
RS Grant Posted January 7, 2009 Share Posted January 7, 2009 The Black Bombshell reputed to be 106dbaD If that car is just over the regulation level, then I'm sure most people will be safe... that car wasn't shy 'back in the day' so I can only imagine its knocked it up a level or two since the last stage of PPP was fitted. Cheers, Grant Link to comment
arch Posted January 7, 2009 Share Posted January 7, 2009 At the Scottish events the measurement is taken at 2/3rds max RPM so in "theory" that would be 4000 revs Link to comment
RA Dunk Posted January 7, 2009 Share Posted January 7, 2009 why have they brought this into affect considering knockhill isnt near any towns/villages/people Link to comment
col666 Posted January 7, 2009 Share Posted January 7, 2009 Would you believe people in Dunfermline were complaining that they can hear the circuit on occasions! I kid you not! Link to comment
terzo neil Posted January 7, 2009 Share Posted January 7, 2009 have they got their hearing aids turned up full Link to comment
RA Dunk Posted January 7, 2009 Share Posted January 7, 2009 Would you believe people in Dunfermline were complaining that they can hear the circuit on occasions! I kid you not! dunfermline is miles away from knockers though, if they hear anything it must be very very minimal to say the least, is this another case of the PC brigade being fuc*wits again ?
