WTF all the Japfest track time is sold out??


Recommended Posts

Not with me, third time running I couldn't go on, so I've now taken it as a sign haha! Donington is more lenient on sound limits and a better track, but I can see why you'd wanna try track closer to home :)

How are the noise levels measured? Does your car get scrutineered before it goes on, or are they sitting at certain parts of the track?



Surely you could put in a silencer insert then remove it lol

Their onsite "exhaust shop" was a load of crap. They didn't have a bung that fit my exhaust, and it wasn't exactly big! (3.5")



They measure sound 0.5-1 metres away at 4-4500rpm (if you tell them you have a lower rev limit they measure it lower)



Phone apps are pretty good at measuring it too so give it a go to be safe
