R34 skyline noise limit

[drifter17a]

Hi all, have an r34 with screamer pipe and want to do some track days

i know can is easily 110db static but not sure what it is driveby, does anyone has similar setup, if so what is tours?

 

Mine is forge engine with g30-770 turbo

Plumb the screamer back so it is quieter and legal, and the track doesn't get shut down due to angry neighbours

win/win/win?

Nah that’s boring, people shouldn’t move in next door to a race track

What track?

Tracks in qld have a few different levels

SMSP has a 95dB limit for track days, however it appears they don't really enforce it, especially when they use the main straight for Roll Racing and those cars are anything but quiet.

Also screamer pipes are such a distraction on track days, you're too busy enjoying the noise to actually be focusing on driving fast lol.

Depends where the microphone is for the noise meter and I don’t think drag racing has the noise restrictions

Apparently it's at the control tower, yeah I know Roll Racing doesn't have it however the irony is they use the same main straight.

My understanding, is SMSP doesn't have an actual noise limit from the Gumbyment. Other tracks do. Hence they opt in / out of who gets noise restrictions on which days.

That is my understanding from like 15 years ago when I was there.

That's so dumb.

It's the age of case of "Even though we can, maybe we shouldn't do it all the time" so they don't annoy everyone

While there's "not a lot" close to EC, that sound does travel.

 

Roll Racing may align with Top Fuel on some nights, so Top Fuel will be way louder, may as well let it be loud at RR.

When WTAC gets in, it's a HUGE event, better open it up a little (Being on the start finish line, it's nicer if cars keep below the 95dba limit).

 

95DBA is pretty darn loud. Especially since it's measured at race tracks at 30m from the edge of the track normally!

So think about how loud a car is when it gets book at over 90dba on the road at 1.5m, and then imagine how much louder it is to get to 95DBA at over 15times the distance...
