Hethel – Lotus Test Track | Saturday 11 March 2023

Static test – A noise meter is placed at a 45 degree angle to the exhaust outlet and 50cm away. The car is then held at 3/4 of its maximum rev limit and the highest reading recorded is the cars recorded noise output for the day. A static limit of 105db is very high and very few cars have an issue with this. At 98db cars with a cat, std factory manifolds and exhausts will generally be ok. Anyone with a very loud exhaust/manifold should be careful.

Drive by – This test is recorded at track side as the car is moving at track speed. Depending on the circuit the reading will be taken between right next to the track and up to 20 meters away. Cars with forced induction tend to have more issues with drive by, even though they tend to pass static tests as the s/c or turbo’s only kick in when run at speed. There are many things that affect drive by readings from wind direction, air temperature, how low the cloud cover is or even what line you are driving.

A sessioned event means that the day will be structured into usually 3 separate groups which take it in turns to go out on track for a set time, normally 20 minutes. Each car will be restricted to their group for the duration of the day. Drivers are generally allocated a group depending on their experience level or type of car.

An Open Pit Lane event means that cars are free to go out onto the track when they choose (providing the circuit limit or our normally reduced limit has not been reached).
