    Predator 212 governing speed

    Stock out of the box Non-Hemi 212. You can see where the governor kicks in. Make sure you back the throttle stop screw out, they have them turned in far enough to kill a noticeable amount of power.

    Comparison data is starting to come in. Since I don't feel the need to constantly explain every single aspect of the build and why it will work the way it does to overbearing skeptics, you'll have to find me on other forums or Facebook for comparison tests and updates.

    The torque arm and load cell are on the opposite side of the pump. There is no moving the engine over there without rearranging the entire setup. I would then have to change my load cell from pulling to compressing, and start all over on the calibrations. Then there is the issue with the...

    You misunderstood me. I'm rotating the engine 180*, not moving it to the other side of the pump. Rotating the engine will allow me to place the sprockets less than 12" apart from center to center. You're assuming I have my code written anything like that. The crank sensor is triggering an...

    Thanks, good to know. I wasn't sure how the video sharing worked. I was previously using MakerPlot with no filtering/smoothing. It worked fine, but I couldn't get a gradual RPM increase. I could get repeatable TQ numbers down to 0.15 ft-lbs as long as I made sure the engine was at the same...

    A screenshot for those that can't view the video. I'm on my phone at work so this is the best I can do for now.

    The torque box is pretty archaic, as is a spring scale. You guys are talking about getting instantaneous torque measurements from sight alone. I've seen guys do this, where they video the dyno pull in slow motion, manually plot out a chart on paper or excel, and then figure up the horsepower...

    Care to elaborate? These pumps are single directional. They will spin in the opposite direction but will not move any fluid. To flip the engine around 180, I would be driving the pump in the opposite direction. So I've ordered a clockwise rotating pump as well. Using a GM crankshaft position...

    Here are some pics from a month or so ago. This is the first design. I've ordered a reverse rotation hydraulic pump that'll allow me to run the engine 180* from the pump to use a much shorter chain.

    A brake and a spring scale is a poor attempt at a dyno. This isn't a novelty dyno. Mine has: -Full dual graphing of HP/TQ and AFR via serial data to a laptop. -Ability to do overlays saved from previous datalogs. -Max/Average numbers and area under the curve. -100 Smoothing factors using an...

    Hello! I decided to sign up while I'm sitting at work and have the time. I'm a DIY'er that likes to build and test things just for the sake of learning. I usually keep that to cars and related electronics, but have since merged those two and started building smaller things that can fit in my...
