996 (1998) PSE question

[DaveN996]

Hi,

I'd like to retrofit PSE and im thinking of going for the Dansk version. 

 

http://www.design911.co.uk/fu/prod13019/Exhaust-Muffler---Silencer-Sports-VALVETRONIC-DesignTek-for-Porsche-996/

 

It works with a Keyfob and I don't like that idea so i'm going to buy an OEM switch for the dash and wire it up...

 

 

Here's the question

I'm assuming the follwoing.  With PSE off there would be no voltage at the vacuum valve in the engine? and the exhaust valves would be closed effectivly muting the system. 

When PSE is switched on 12v is applied the a vacuum soleniod and it opens allowing vacuum the the exhasut??

 

If my assumptions are correct then is will be fairly simple to make my own control relay instead of using the keyfob.  

I'm trying to make it look as standard as possible.

 

 

Cheers,

 

 

Dave

Porsche PSE valves are normally open (loud).

A vacuum triggered from the solenoid switch causes the valves to close (quiet mode).

 

I'll let others here say whether the Dansk PSE has resonance and drone. A number of after-market systems do and they tend to drive people crazy. So buyer beware...

Thanks Loren.
