see sig, This was going through the traps at 75 defeuled, I could not get overdrive so was speed limited, I have since added a computer bypass switch so that I can force it into od, but did not get a chance to rerun before track closed for season. New England Dragway is only about 10 miles from home. If you do a search you should come up with more peoples times, I think I posted when I ran something like. . "1/4 mile vs rear wheal hp"it would have been back in October... . I was the only Cummins running that night, there was a new Duramax...
