[QUOTE="tt335ci03cobra, post: 15524148, member: 68944"] Converter slip is problematic, but the major reason that such calculators don't seem accurate is because a tire grow in size by the big end of the track. About 2" of growth to be honest (stretching really). So if you had a 28" tire, it's going to grow about an inch ever 75mph rough. At 150mph, it's about a 30" tall tire. If you redo calculations with 30" (assuming your calculating trap speed) it'll be bang on. Converter slip is a factor in the 1/8th and 1/16th for sure, but by the 1/4, and beyond its usually pretty well locked and loaded. [/QUOTE]
