Trackday noise

• Page 1 of 1
I have just signed up for the Castle Coombe Trackday and the receipt and instructions arrived yesterday. There are warnings about noise tests before being allowed on the track. A maximum of 100 dB is allowed. I am a worried about the noise level from my +2. I assume the silencer is standard and is working properly - but dont know. To my uncalibrated ear it sounds quite loud - but no louder than many saxos.
The questions are: will it be OK? How do I find for sure? or what should I do? How could I get it tested before I go? should I just fit a new silencer?
All suggestions welcome.
best regards, iain

I've been told that Maplins are selling a meter for around ?30 if you want to be sure, but a standard +2 should be fine. Last year Castle Combe had little additional silencers that clamped onto the tail pipes of cars that exceeded the noise limit, but I only saw them on Europas...

Thanks, Simon. I'll check the maplin device.
Do you know if the extra clamp-on silencers are available on the day? Or where you can get them? It sounds a useful thing to have.

I have also just signed up for the trackday and I am also worried about how loud my car is
I have just checked the maplin web site and they are out of stock. I guess I will just cross my fingers and hope I get to run.
See you there for big grins all round

Steve,
I was speaking to Roy at Paul Matty's. (he will also be there with his +2). He reckons a new silencer on a +2 will be all right at ~98 or 99dB, so I have ordered one. It should make motorways easier too. Also, I have heard that Merlin Motorsport based at Castle Coombe sell a small supplementary silencer to clamp-on to the tail pipe. Worst case, could get one those on the day....

I think to noise test your wife you need to let her see an invoice for Lotus parts then measure the reaction
.............sorry, I'm not that brave

[quote="steveww"]Thnaks for the tip. I have just ordered one. So if anyone wants a noise test you know where to come.
Steve, did the noise meter arrive? Do you think it is accurate?
I have fitted the new silencer - so am ready for Castle Coombe... It's quieter, but still sounds interesting at 5000 rpm.
