Here is some video of the Dyno runs. For anyone that has not done something like this it is exciting in an odd way.
I am sure I will be corrected if I am wrong. The motor is brought above 3,000, the dyno loads it down below 2,800 then the pull is made. In this case to 6,000 and the result is calculated to 5,800.

It was interesting to watch Barry who has obviously done this thousands of times. He starts sitting on a stool, tenses up as it begins. When he nails the throttle he stands up abruptly and you swear he outputs half the HP of the engine.
We had two interesting experiences.
On one of the first pulls which I don't even think was full RPM an exhaust pipe popped off. They are just friction clamped on so I guess it is not that uncommon. BUT to go from loud, to open header loud in the building sounds like an explosion! It shocked me for sure. I would count that as the first time that engine made me poop myself a bit.
Then later (when I was experienced and a cool customer) High in the RPM range the
oil pressure sending hose blew. Best I can tell as the hose was losing pressure it whipped around passing the header and lighting the stream on fire. That lit stream then passed in front of the hose connection on top of the
oil filter which was an elbow facing right at the cell window. That lit and shot a huge fireball right at the window. It was crazy, Barry who was cool as a cucumber when the exhaust popped of yells HOLY S_IT and makes a b line for the door. He said as soon as he got through the door he saw it was the
oil pressure hose, no big deal. Unfortunately the floor was covered in oil and down he went. We could see on the pull data that he shut it down before the pressure dropped so nothing got hurt. It was actually funny when all was said and done except Barry got banged up a bit. Unfortunately no video.
That would be the second time that engine nearly made me crap myself. I wonder what will happen when I get it in the car?
The bad news is that took an hour or so to clean up which was part of what limited the dyno time.
