To those that ask why the non SVT 2.5L and 3.0L "seem" to have less failures I would suggest this..
SVTs rev higher/faster/more often. Correct me if I am wrong (Judge?) but I expect that harmonics may increase at higher RPMs. You have seen SVT dynos - peak power AT or NEAR 7000 RPM fuel cut (compared with peaks around 5600-6000 RPM for the strongest SE/Cougars). Combined with lighter SVT flywheel (an additional effect on harmonics???) the SVT ON AVERAGE will spend much more time above 6000 RPM to wring out the power - except for all but the hardest driving Cougar/SE guys who represent a minority. And the 3L in the taurus/sable has the ATX which hardly ever sees >5000 RPM (I know, my wife has one). To me it makes sense that the SVTs (which are also overrepresnted here at CEG so you hear more) may have more failures. Premature failures DO occur with SEs and now even a few Cougars (3?) so it is not limited to SVTs - just more common (?). And the high RPM factor may expose SVT to more oil starvation as well based on the Roush data (minimal oil in oan at 5000 RPM).
Just my thoughts but I think dual mode damper is more critical for SVT & non SVTs who really rev it. I have not installed the DM yet (probably early March) but will give feedback.
Another Kudos to Aussie and Terry for making the DM available.
