I've learned to only believe horsepower claims when they are backed by a dyno sheet and complete specs on the engine. I guess for me it would come down to one of those, "it's your story, tell it any way you want" deals...... The first time we rented Andy and his chassis dyno to come to our fall show, there was a bunch of 600-800 horse engines that could only record about 300 on the dyno!!!! Must of been a bad air day I guess.
