SVA noise requirements

[alackofspeed]

Does anyone have a digital copy of the SVA manual? I'm wanting to check my car's noise levels against the rules.

For the honda builders:

I'm running a 200 cell cat, and the Marlin silencer. Noise levels @ 1m and 45 degrees to the exhaust (no body fitted) are:

Idle (750 rpm) - 68.6 dBA
2k - 70.6 dBA
3k - 73.6 dBA
4k - 75.1 dBA
5k - 77.2 dBA

In jist it seems, to me, pretty quiet when not under load.

Found the answer

101 dBA @ 75% of max power revs, @ 500mm.

max power is at 7400 rpm, so 5550 for 75%....... problem is there's a rev limiter at 5500 when the car is stationary .

I've now tested the car:

@5500 rpm, just clipping the rev limiter under SVA distance requirements results in 95.6dBA... so the Marlin standard silencer is pretty close to the limit.
