You aren't a million miles from Cadwell Park, near Louth. Head over there when there is a trackday on, or even head over on the Club trackday, and they will be happy to static test you. Be warned that a static pass is only half the story, as a car can sound totally different when loaded right up and driveby noise meters get blown apart. Been there, done that, got the T-shirt, did one warm-ish lap, got told to go home. PS. I fully respect noise restrictions at airfields and circuits, otherwise we may not have them to drive on.
