Message For those of you that have been there, since this is where our main "track day" for ZCON 2017 will be:

How "enforced" is the sound limit of 85dB at the fence? It has never been an issue at other tracks I've been to (TWS, MSR-Cresson, COTA, Hallett), but I've never been to Harris Hill before. My Z (RB26 swapped) has external wastegates that vent to atmosphere (see: "screamer pipes") and under boost are quite loud. The exhaust otherwise has a modified B&B 3" quad oval exhaust so it isn't unreasonably loud. Thanks in advance.
