Wasn't my ZDZ and I suspect the owner neglected to mention we were pulling the bejeebers out of it on the dyno looking for his missing 2.5 hp when it went boom. I heard they told him it would be many moons before he would see a replacement. I can tell you this though the only way that motor was going to make 9 hp was if we gave it a 3 hp shot of N2O.
