BogMonster Posted December 8, 2005 Share Posted December 8, 2005 Just received a couple of sets of Mill Services lifters today, different sizes to give me a choice of what to do with the back end of the 90 to restore some altitude. Good timing as it is a public holiday here tomorrow, to remember the Navy beating the Germans 2200-6 a few years back (and we thought 5-1 was good...) I know that 2" or more of lift at the front can give propshaft vibrations (as I found out...) but what are people's experiences at the back? I have 2 sizes of lifters 1" and 1.5", plus the rubber isolator rings which add another 0.3" approx so 1.3" or 1.8". My feeling is that either is likely to be OK but I just wondered if anybody else has had prop vibrations on the back, or if it only affects the front? I haven't measured but I think the back prop is longer so presumably less of a problem. But still keen to avoid having the whole lot off several times as I did with the front Ta Stephen Quote Link to comment Share on other sites More sharing options...
