How loud?

[SprintSpeciale]

Does anyone know the noise rating of a factory standard 2012 Granturismo Sport? I am booked to take it to Goodowood but I was told that Maseratis are loud and asked if I am sure it will pass the noise test - it's a 90db limit.

I'm assuming you mean 98db? They don't do 90db days afaik. And you'll almost certainly fail - you need a 105db day for one of those I'm afraid.

[SprintSpeciale]

Yes, sorry, I meant 98.
Looks like I'll have to take the oldie then.

I took my 997 GT3 with a standard exhaust and they measured it at 106dB at 3/4 max revs, so good luck!

Looks like I will need to use one of the Alfas instead Ho hum.

two points here

If Goodwood is at all stony, you will wish you had taken the Alfa anyway

If you have an iphone, download an app called Decibel10th. Its free and I have found it to be accurate.
Then get someone to sit in the car, warm it up and rev to 3/4 max revs and see what reading you get.
You need to hold the phone a metre away, 45 degrees both to the side and up from the tail pipe.
I cannot guarantee accuracy, but my car was 98 dB at Snetterton, and measures 98dB on that app.

98 is remarkably low. Most trackdays are between 101 and 105 dB

Thanks. And nice car.

Goodwood has been 98dB for some time now, it's the classic problem of a load of pensioners in new builds complaining to the council, even though the track is likely older than them, let alone their houses. Chichester have just rolled out a 20mph speed limit for much the same reason.

Nope. I have just been staring at the front of my car after a stony track day.....yuk.

[SprintSpeciale]

I have just used this 98db development (and dire warnings of pebble dashing the bonnet) to press on Mrs SS the urgency of acquiring another car specifically for track days...

dB

98dB is probably about the loudest the iPhone could accurately measure, certainly can't deal with anything over 100dB

Hmmmmm. I did wonder. I have organised some bolt ons from a friend for Monday. 101db limit.
