Just another MMP Stage 3 Dyno

The motor in this thread is built?

Built short block from Motiv. OE compression and stock head / cams so no effect on power.

OK, I am so confused. Here is my dyno in 4th gear on a 6MT. My torque at about 6200 RPM is about 450 ft-lb. And I am at about 561 WHP. And using this calculator, my WHP seems to be correct.

So the op's dyno shows lower torque and records higher WHP???? What is going on?

The OP used e85. Anything over 600 is e85 territory. What gas did you use?

I think the confusion is the graph. Since it's using MPH and not rpm, you can't use the same scale of them matching up, or the dyno has torque"guessed" wrong. A dynojet in inertia mode 'measures' HP and calculates torque basically. We can assume that the op's HP from the graph of 648 is at 7000 rpm in 4th gear. Based on that, the torque at that point is 486. We really need a proper graph with RPM.
