    PSE dB levels (for track days)

    Does anyone know what the dB level is for a Carrera S with a Porsche Sports Exhaust fitted?

    Here in the UK most of our track days have noise restrictions. So I don't want to sign up for an event without first knowing whether I will be even let on the track.

    Note I cannot switch the PSE off without having the Sport Button of too, which rather spoils track fun!

    Many thanks,

    Dont know the exact db but would be very surprised if PSE exceeded a race track restriction.......

    DC just reported on the Boxster Board that a 987 S (3.4) fitted with PSE will create a max. of 106 db

    Of course it depends on the track-layout (topography, full speed legs etc.) whether you reach the noise top level.
    A lot of European tracks set the allowed limit @ 95 db, but of course they don't measure noise emissions all the time
    I'd ask the OPC about the specific data for your car and then I would talk to some guys who already have been to the track you want to visit (rules/policies etc.)

    Hello Porsche-jeck,
    I had a similar problem with my europipe exhaust at Zolder-circuit in Belgium.
    I Was very careful when passing by the 2 measurepoints.
    You get only ones a second chance after exceeding the limit.
    At the end of the day i asked for my listing of measurements(so i got my laptimes at once) end i never got passed the limit just 94.9

    You can switch the PSE ON/OFF without ever touching the Sports button (which is nice, because you can have the PSE on LOUD, without being in Sport Mode , and vice versa)


    All you need do is to splice a DPDT ( on-off-on )switch into the 12 V power wire (purple/red wire )going to the PSE solenoid valve in the engine compartment(the one with the orange plug) and connect it to any 12 V power source (like your cigarette lighter in the console )

    When there is NO power to the N/C solenoid , the valve CLOSES and that in turn CLOSES the vacuum line.
    The PSE valves in the exhaust pipes are normally OPEN (spring activated )and are CLOSED by the cars vacuum system .

    No power to the solenoid, solenoid closes ,therefore no vacuum to the PSE valves, valves stay open , PSE is LOUD.

    12 V to the solenoid, solenoid OPENS, and allows cars vacuum to CLOSE the PSE valves, car is QUIET .

    Simple . Lol
