Cole,
Thx! Very resourceful.
Yes, Jerry Woods is a great thought. Years ago Brent 930 sent his dist to them. I recall them wanting the throttle body to so they probably changed the vac to a full on connection instead of a modified ported one. I believe they abandon the Vac-Retard side which I assume makes is more like a Euro Dist. The also recurved it which I assumee was for faster advance. Someone should get with them and find out what there program truly is if they will disclose what they do.
I have to ask, are you sure about there only being 4 deg of on boost timing retard and they you end up at -24 on boost? From what I have learned a 930 has about 9 deg of retard and should be at about -16 at full boost. I know that is for a US dist but I would not expect much difference except for the total advance. I have to say, until I looked into it, I thought that they were at -25 on boost to. I believe my 3.2 Carrera is only about -25 at WOT, it is a higher compression, and dose not see any boost.
From 911Chips.com web site:
Note full advance by 2500rpm.
The best.
