is 997 GT3 noise ok for Goodwood?
Discussion
I dont know how noisey 997,s are but If you get on at 98db Static you may find you are marginal on the drive buy at 101db. My 996 was flaged for reaching 100.7 this is aparently because if they trip 101 its an hour shutdown and you will not make yourself popular ring the circit and ask Mark Fetherstone(Circit Mgr)very nice chap, he will tell you what days you will get on.
I love Goodwood but noise is an issue especially with my car (race cats and cans).They are very strict as the council are strict with them. The council noise moniters are at the chicane,StMarys and Lavant last time I was there I pulled 100.7db at lavant and the chicane but felt slighted that i was obvusly no way near through no name/stmarys I must get faster through there.

I assume that the Goodwood circuit gets a special licence for making noise on its Revivals weekend. I was there on Friday and there were lots of cars making a fantastic level of noise. Much as I enjoyed watching and hearing them, there were some that were truly painful on the ears from a trackside position!
The noise naz..ahem police are very strict at GW. Unable to be creative with redline due to head being shoved through window. My GT3 Mk1 was 103 static so no chance. They do some 105db days but not that many. Upon leaving I made sure that I did a few full bore accelerations around the surrounding countryside because I am allowed to!!!
There was a thread recently on some bolt-on 997 mufflers that brought the static down to 98db with minimal loss of power.

Sorry Batman but you cannot criticise the Goodwood marshals for enforcing noise regs on a quirt day, if you had gone on and tripped the drivebys at noname,lavent or the chicane you would have ruined the day for a lot of other paying punters the reason I know this is some nob in a 360CS did this on a day I was on.There was a thread recently on some bolt-on 997 mufflers that brought the static down to 98db with minimal loss of power.
If you dont like the noise restrictions become a west sussex councelor and cahange then dont have a pop at the marshals
Hi everyone,
Been reading this for 3 to 4 months and have enjoyed. Just did full track day at Goodwood with the PCGB on Aug 2. Have accquired a new GT3 this summer and broke her in at Goodwood. Did the usual noise rev job with officials before started tracking and they said it was border line but ok and mentioned they would keep a look out for any excess sound levels. Also placed a small blue sticked on windowscreen saying 105db. Raced all day no problems and even put my sports button down for the the afternoon sessions. Its a fantastic circuit, very quick bends and corners and very satisfying to drive. See PCGB INFO BELOW. Did Silverstone last Sunday and have booked Castle Coombe for 20th Sept (4th time) and Spa 8th,9th Oct with Autotrack.
Happy motoring
"Noise - Circuits are coming under increasing pressure from local residents and various environmental groups regarding noise issues. Some circuits have more difficulties than others and therefore are required to operate to differing noise limits. Most of the circuits that the Club uses, including Goodwood, operate to a noise limit of 105 dBA. This will usually mean that all standard Porsches will not have a problem, even 911's - the 964 type with 'Sport Exhaust' usually being the worst example, tending to measure 104-105 dBA. Bedford is also subject to relatively tight restrictions and a drive by test of 97dB(A) applies, again the 964 model with a Sport Exhaust can be used, if a little 'restraint' is displayed. Castle Combe in Wiltshire is the circuit with the tightest noise limits, at 100 dB(A). This means that only cars with standard exhaust systems will be allowed on track. Anything non-standard is likely to be too noisy."

When I went to the Porsche Club trackday at Goodwood in late July,an orange 997RS and a white 997GT3 managed to get on track with no problems. The RS was much quieter as the owner had done a few mods cos of noise issues.
The white GT3 was LOUD!!!!!!!!!!!!!!!!!!!! The owner must have had the sport button switched on permanently. Don't know how he didn't get black flagged but must back off near the noise sensors. Sounded awesome!

The sport button doesn't make a lot of difference at high revs if you are flat out. Either way the car will be fine on a 105db day, its just the 98 it won't. The problem with the 105db days is that they only allow 5 cars on track at a time, which means you spend a lot of time waiting to get on track.Gassing Station | Porsche General | Top of Page | What's New | My Stuff
