The 128mph pass was at 18 psi.....I really want to get the 727 to work for me....I feel I may have had something out of wack the last time I put the trans back together because I had about 50 passes on it before and the clutches looked good after I tore the trans down to fix the broken planetary.
Now that was with less power but I still had numerous 120mph+ 1/8th mile passes before.
