I haven't really put my Mosers to the test yet but they should easily be able to get into the 1.4's on a full wieght car based on other's experience when I researched them when I bought them. My car cuts 1.50 60's on drag radials and I broke a stock axle. Since going to the Mosers I haven't had any problems but I haven't had any 60's quicker than low 1.5's so far. I may try some slicks later in the fall and I will try to test them little harder!:biggrin:
