'Dis ... (NOW BOOST PROBLEMS)

[Claus Vegener]

I have seen it without use of wgfv too at max boost
(using a spring load to 2.5 Bar) and when this happens
normaly found a minor leak - or a bigger some days later.
Wormgears around rubber hoses make an elastick tightning. At one point the break through starts and
when the pressuer are released it seals again -- I think.
I have had 2.7 Bar without flutter.
I  T-on my gauge just before the gasolin trap.
I have had 10 psi flutter / 1 sec = lose wormgear
I have had +/- 0.5 psi 3 times/sec for smal leaks close to
idle system
