TVR Zolder Continental Meeting 2020
Discussion
Buoyed by the success of the recent Cadwell Park trackday this year, a few of us from TVRCC NL and TVRCC GB want to resurrect the TVR Continental Meeting at Zolder for 2020.
This is usually a Friday TVR only track day at the Zolder circuit in Belgium (there’s the option of a day trip to Maastrict for uninterested nontrackdayers) followed by a light heart awards evening meal in a decent hotel in Holland. On the Saturday there is the option of a Treasure Hunt/Orientation for people who want to stay in the local area; or there are the delights of Amsterdam, Brussels or Dusseldorf if you want to make a City break weekender of it. If you are a total petrol head; Spa, the Nurburgring, and the Michael Schumacher Karting Centre are an hour or so away.
Zolder is about 170 miles from Calais and 110 miles from Zeebrugge/Rotterdam. We’re looking at doing it in May or June 2020. We could do with a provisional show of numbers, so please add your name here if you think you might be interested?
The drive-by noise is increased from 95db to 98db. And the TVRCC NL are intending to use the Van Der Valk motel at Heerlen. Booking details to follow.

The sensors are apparently at the start of the back straight (coming off a 85 degree right hander) and just after the top of the 2nd hill, which is a left hander kink. I would have thought they would be at the end of the straights, before the breaking zone, where you should be at maximum rpm, rather than accelerating in third gear at (I am guessing) probably 4750-5250 rpm going upwards?
In UK we usually measure dB using a sound meter on a 50 cm distance stick pointing at one exhaust (so it will pick up some noise from the other exhaust) on a static car, revved to that circa 5000rpm.
The Zolder limit is 98dB drive by.
Sound dB is governed by Inverse Square Law, which roughly suggests that sound decreases by 6dB each time you double the measuring distance. I do not know which side of the track the sensors are on, but I guess they must be at least 100cm from the track edge, maybe 200cm. So if your car is 110dB in UK; at Zolder it will be 104dB at 100cm and 98dBb at 200cm and that assumes you are right at the track edge; if you haven't got the racing line right, you could be 400cm (92dB) away from the sensor……..
That's the theory, but remember I am a second hand car salesman, so I am really thick! And I don't know exactly where the sensors are in relation to the circuit tarmac. Don't trust my maths above. And "drive by" is going to pick noise up from the tyres, the induction, the screaming passenger etc.
I have done Zolder in lots of different standard exhausted TVRs over the years no problem. Or like John Simpson says, if you know where to lift off...…...

Hi Ginkent - You are right. If you can get noise tested before you go is probably the way forward. If you have just changed the back box to a sports back box, buy/borrow a secondhand standard back box, especially if you think you might do more track days, as the noise rules are only going one way. At Zolder, you see Tuscan/Sagaris owners turning up and switching their end cans (but it's obviously fairly easy on those cars). I have however asked the TVRCCNL to clarify their track refunds policy for people who get black flagged for this next event (info to follow).
Hi MkIfan - There is a joining booklet giving track driving/overtaking instructions. (Yes, which I guess people don't read properly.) Cars are tested (unlike UK) before the trackday and there, they are pretty keep on engine mounts/fuel lines etc. If you come and see rotten driving on track, let the TVRCCNL know and they will do something about it.

Hi QBee - It's not as bad as your post suggests, certainly a lot better driving standards than The Nurburgring.
If there were a formal drivers' briefing, you would need to do it in Flemish, French, German and English, so it would take up too much time. However, there is a Welcome to Zolder (sort of briefing) and an Introduction to Zolder (ducks and drakes) from 0830-1000 which newbies are meant to do. The track day then starts properly from 1000 hrs, which is when most regulars turn up.
The track is marshalled by the Zolder circuit; the TVRCCNL run the pit lane; so same as Cadwell TVRCCGB.
