Noise: Static & Drive-by

[The Old Italian]

Over in the Elan lounge I've posted a question as to where I can find a track prepared Elan suitable for trackdays, but it's just occured to me that maybe exhaust or induction noise on a non-standard car
would rule it out at circuits that have unsympathetic noise limits.

I know that the specs will vary but can anybody please share their noise testing results
so that I can get a spectrum of what to expect.

Thanks.
Ian.

Ian,

I see you have no replies yet, so FWIW, I remembered posts in the archives wrt measurement issues and grief with a "standard car" at Castle Coombe.

Hopefully things have improved since then..no doubt others will be along soon to update on current practices...

If you point the exhaust tip toward the ground it helps lower

Thing is if you do that in a paddock that is dusty, you really hack off your neighbour - the dust goes everywhere.
