Well we finally ran a GT with off road H pipe and flowmaster cat back and NT555R's drag radials, with the Maxima. First we went heads up. I was in the GT and video taped from there. We went on the 3rd honk, and the GT jumped out right ou the box while the max was fighting traction in 1st and 2nd. So the max let out!! We figured the we should go from a roll on the interstate so we did. Once on the interstate we got to 45 mph in 2nd and went on the 3rd honk again. This time the max stayed side by side with the GT till about 85-90 mph. When the GT hit 4th he pulled 4 cars on the max. At about 135 in 5th the GT was getting pulled back in by the Max. The max was doing 150 when he got beside the mustang. It seemed like once in 5th the GT did not pull any more mph. It stayed at 135/137. I quess that is the stock 3.27 not letting it pull 5th. Any way it was a fun run. I'll try to get my friend paul to post the video.
