GlennK Posted August 22, 2011 Share Posted August 22, 2011 I got a noise test done in readiness for track day(s) coming up; 102dBA at 4500rpm, 104dBA at 5200rpm. Both at specified distance of 0.5m, 45deg angle, on hard surface. So looks like I'm banned from Thruxton, Goodwood (Saturdays), Castle Coombe and Bedford!! But game on for Goodwood weekdays, Brands Hatch and maybe Silverstone (it's 102dBA so on the limit).... Still, aim is to get a couple of track days in before the end of the season.

Geo Posted August 22, 2011 Share Posted August 22, 2011 can you not just use a bung ? Quote Link to comment Share on other sites More sharing options...
Heyrick Posted August 22, 2011 Share Posted August 22, 2011 What exhaust set up is that? Info could be added here: http://www.mkivsupra.net/vbb/showthread.php?217156-Exhaust-dB-register&highlight=exhaust+register Quote Link to comment Share on other sites More sharing options...

Chris Wilson Posted August 22, 2011 Share Posted August 22, 2011 VERY marginal, I'd change the exhaust to something much quieter. I get 98 to 100 Db on my Skyline the testing always varies. Quote Link to comment Share on other sites More sharing options...
GlennK Posted August 22, 2011 Author Share Posted August 22, 2011 Thanks guys. As I recall it's an HKS 3" straight through fully decatted. And the idle level is 94dBA... I'll check later and add to the exhaust dB register. Tried a bung but it gets a bit stuffy and hot in the cabin after a few minutes...cough cough.
