Re: 8V vs 16V vacuum advance capsule Posted by 900 Aero [Email] ![]() ![]() In Reply to: 8V vs 16V vacuum advance capsule, Jeff Cullen, Sun, 8 Aug 2010 09:15:59 Members do not see ads below this line. - Help Keep This Site Online - Signup |
Hi Jeff, the '84 8V capsule uses longer springs on both the advance and retard sides of the diaphragm but with a smaller wire size so they probably compress to about the same pressure, just a little different rate. You will have to bend the stop .75mm (.030") downward to achieve the same retard limit because the 8V actuator arm has .030" less where it contacts the stop. My 16V Adjustable Ignition Diaphragm actuator arms are cut -.040" to get the retard limit to where there's little to no additional adjustment necessary so the 8V units are actually closer than the 16V ones are! Just bend the stop .030" to .040" towards the distributor and you'll be fine. I've already cut the only real nice 8V capsule open I have or I could have just sent it to you however you never know what condition the diaphragms themselves are in until the unit's are cut open. A good place to find usable ones are from '86 to '89 9000T's (the later the better) where they're not right on top of the turbo!
