Likely a result of the 5th gear pull.
What is? Ideally it should have been dyno'd in 6th gear (1:1).

The dyno results not intersecting at 5250. The large delta between the torque (+100) and HP probably gives a different axis.What is? Ideally it should have been dyno'd in 6th gear (1:1).

No, it isnt always how it works, especially when there are large delta between measured HP and torque if forced scaling isnt used.Yeah... That's not at all how that works. HP and TQ always intersect at 5252; perhaps you should look up the formula. In WinPEP you can adjust the axes however you see fit to compare the curves; the standard is to have both on the same scale, though (which means they'll cross at 5252, per the math).

I'm not challenging the math, I'm very familiar with dynos. The fact is, your graph wont intersect all the time; doesn't change your HP or torque. It's just a display issue.Mathematically HP=TQ at 5252RPM. The nuances of the WinPEP software and whether you force scaling or not, does not change the calculation.
14% drivetrain loss is prevalent for newer vehicles.So, can anyone interpolate what the crankshaft HP and torque should be, based on the C & D dyno test?
Thanks. Does that apply to torque too? Someone said this is for HP only, torque actually works differently.14% drivetrain loss is prevalent for newer vehicles.
Yeah, so what does the difference between Toyotas claimed 365 lb ft, and the dynos 427, mean? If the crankshaft HP is between 390-400, what would the torque be based on Toyotas claimed, and the dyno reading?Torque is a product of gear ratios, diff ratios, wheel diameter, and in this case, torque multiplication through the converter.
I'd imagine it to look a lot like this one (also lacking the particulate filter).Yeah, so what does the difference between Toyotas claimed 365 lb ft, and the dynos 427, mean? If the crankshaft HP is between 390-400, what would the torque be based on Toyotas claimed, and the dyno reading?
