Heb een beetje onderzoek gedaan naar de vacuumvervroeger mod en heb dit gevonden:
Bennie, this is indeed a DIY mod. I'll see if I can explain it as well as it was explained to me!!
First, pull off the ignition diaphram. If you hold it in your hand you can pull the diaphram arm down, and see the movement it makes. There is a stop that protrudes from the side of the unit that limits the travel of this arm. (it's not hard to find, its a round peg sticking out, held in by a rivet.
Pretty much, you get some pliers and grab the peg (one jaw on the outside, on the rivet. the other jaw of the pliers on top of the peg). When the funny-looking arm is at rest, you can see the distance between the step in the arm and the peg. Bend the peg BACK so you increase this distance (about twice the amount).
At this point you have increased the range of the retard under boost. What you can now do is increase your timing from 16 to something like 18 to 20, while keeping the retard under boost at 10 or so. Hard to visualize without holding it in your hand, but i hope that helps.
Heb deze mod vandaag even gedaan maar nog niet uitgetest
.
Volgens velen die het hebben gedaan heb je met deze modificatie minder snel pingel (dus je kan hogere turbodruk rijden
), en een aantal pk,s erbij dus zeker de moeite waard en het kost je niks!

Gr, Bennie
