Can a few of you veterans out there please offer feedback regarding this dynograph?
This is new to me, but I am skeptical here. (IMG:style_emoticons/default/confused24.gif) Thanks! Mike in Munich Attached thumbnail(s) ![]() |

Update: I never did get values for the AFR, but we did discover that the throttle wasn't opening all the way. Apparently the accelerator pedal stop screw in the floorboard was out too far.
New results were somewhat better but not much. Max torque was 106 at around 3500 rpm, HP at the flywheel maxed out at just under 95, allowing for 15% loss in the drive train. Power drops off by 5 HP between 4500 and 5000 RPM and more steeply after that. Compared to the original results, max torque went up from 94 to 106 and max HP went from 76 to 81. Supposedly the engine was not fully warm at the time of the test. The results, as you can see, got better with each run. Not sure if the engine was fully warm at the time of the last temp. At optimum temp we might be able to eek out 100 HP. I was told that in the graph below...Green is in 3rd gear, Red is in 2nd, Blue is in 4th. I was told that the blue line is jagged because it is in 4th gear. Jake Raby chimes in below and suggests that the reason for this is that the plugs are fouled. But they are brand new. Looking into it... Strange is that the torque and RPM intersect at 4300 and not at 5200 where they should. ?? Dave Darling however comments on the likely reason for this below. M.i.M.
