964 3.3 turbo CIS system pressure

Recommended Posts

Anybody who can take away my confusion:

In a '91 Service Information booklet I read the system pressure for the CIS in 3.3 turbo version (lambda controlled) of the 964 should be app. 7,0 bar.

However, if I check other publications about the Warm Up Regulator pressure values (type 0438140160 / 965606010500), I read a system pressure of  6,4 bar.

 

Honestly speaking, the service information booklet bring tons of interesting information, but I fear I have to take that value in doubt.

 Anybody that can confirm the right system pressure value is 6,4 bar (plus minus 0,1)?

 

many thanks!
