To get a more accurate reading you need the hydraulic oil reservoir full to the top of the cooling coil. oil temp needs to be in the green and RPMS at the "540" nark. if your RPMs are not on 540, the reading on the gauge will be inaccurate. I spent way too much time learning exactly how these work having to rebuild my dyno. I found that 30-50 degrees in oil temp can throw the reading off 5ish hp too. if you want to read the HP at different RPM's you need the slide rule that came with the Dyno's new. Great video though!
Thats a healthy good ole 1206 you have there really nice , I had a nice 1066 that put out 121 hp and should be closer to 130 yours went the right way and good video and subd !
Never dynoed mine, but it will eat the clutch if worked to the extreme on a continual basis. Had the same issue with out turbocharged 806 before we put in the after market heavy duty clutch kit in.
I sold a 1206 in the early 90’s back when they were still cheap for $4,500 and I sure wish I had it back now. I seen a Oliver 4 digit sitting in the barn there what’s the story on it
