Took it to "local" track, 1/8 mile. Immediately ran half second faster than my best time with the old engine 1100 converter and 2.41s. its not that impressive but my best run was the 3rd and final at 9.5 @75 mph. converter is super tight at barely 2k, and my 60 foot is *ss at 2.18 at best. best reaction time was .2294 on the 3rd run.
