paulyb Posted February 20, 2002 Share Posted February 20, 2002 Anyone any idea how many dB's I can expect from a 2001 SLR. Was hoping to Goodwood trackday in March but the limit there is 98dB so now I'm worried I won't get on. Thanks in advance. Link to comment Share on other sites More sharing options...
Jam Mad Posted February 20, 2002 Share Posted February 20, 2002 on the same topic, 'cos this is something that is bothering me too, does anyone know whether any garages or anywhere keep the noise measuring equipment ? that way we could just trundle on down to them and find out. j Link to comment Share on other sites More sharing options...
Graham Sewell Posted February 20, 2002 Share Posted February 20, 2002 Except that noise levels differ day to day let alone circuit to circuit. Plus a some limits are at drive by, which adds a whole series of complications. The only advantage of going to a garage to get it tested is that you will have some clue if you are close to the limit... Low tech luddite - xflow and proud!

allegro Posted February 20, 2002 Share Posted February 20, 2002 My 2001 SLR belts out 98db at 4500 - 5000revs. Or at least it did 4 months ago. I have a suspicion it may be a little higher now. I have a DB meter. If you want to check your sound levels, you are welcome to pop by and make some noise on my driveway. I live in Wokingham, Berks.

jerrypike Posted February 24, 2002 Share Posted February 24, 2002 paulyb goodwood quiet days are 98dB, noisy 105 dB both @3/4 rpm as previous postings, meters vary, best bet is to go to goodwood and ask them to noise test you (phone first). the meter there is quite kind, but there is also the drive by metering which may need an early change on the start straight if you're close to the limit. this also depends what other cars are out with you as this is for overall noise. who are you going with? some organisers will refund if you fail, most won't jerry Link to comment Share on other sites More sharing options...
