No reason to get a attitude, I think Mike's a good guy, he did quality machine work and I honestly think he BELIEVED his engines made the power he was told. But there are examples....a certain blue dart on this site...I think the claim was 540 dyno horsepower, it was then installed, taken to a chassis dyno where I think they said they picked up 20 or 30 MORE horses, then taken to the track where it ran like 114 MPH at 3100 odd pounds...the track doesn't lie, but dyno do!
