Brooks,
Could we bother you for your battery part number, just so we'll know which batteries provide the power you log on the dyno and the acceleration you show on DragTimes videos?
Those of us with P90DL's want to keep track as we upgrade to P100D's, just in case there ends up being more than one version.
Thx.
The hp number is actually kind of impressive, from a Mustang dyno. For bragging rights you could go to a Dyno jet, they put out higher hp numbers.
If I were in the business of designing dynos, I'd just print out 20% more power than measured, mine would definitely be the most used!
I'm no pro at this stuff, but I think torque is torque regardless of RPM. In an ICE you need RPM to derive HP from the torque reading.While this does seem awesome, was there an RPM pickup on the motor? I'm guessing that wasn't possible. What do the torque numbers mean without RPM? Sure, we expect torque at the wheels to be huge, due to the gear ratio, but I think it needs to be corrected by RPM to be comparable to an engine torque figure. Even then, I'm not sure we can directly compare this number to any ICE car...

No.then don't we know all we need to know?
That's why I don't care about EV's torque numbers anymore, almost nobody gets it right, especially not the tools that own the dynos. Hp it the important factor here and 580 is impressive.
Well, you don't know those regardless of what you've strapped to the dyno.No.
We do not know the fudge factors the dyno uses to cook the Engine power and Engine torque values.
Both numbers are important. Problem is the industry got used to reporting torque at some RPM of the engine.
What is really meaningful is wheel torque at different speeds. That is what you feel in the car (adjusted by car weight).
True the car's weight makes a big difference. What matters is acceleration. That's what you feel. 0 to 60 in 3 seconds is an absolute value. 600 HP without the car's weight doesn't tell you anything about how quick it is.
Torque is the rotational force. That's what any dyno measures. HP is calculated using the measured torque at a certain RPM. So in order to get correct HP numbers the torque has to be correct.
HP really isn't the right measure for a car. Torque is. Torque is how strong the wheels spin. That's what makes the car go.
Yea but they "measured" 920lf-ft of torque, which can't be at the wheels, or it would take some 14 seconds to get to 60
