P3D+ 1/8 Mile tested: with and w/o Track Mode (Bonus Video vs. Dual Motor AWD)

[Daniel in SD]

Trap speed is a much better indicator of power than ET. Track mode has less power but slightly better torque off the line (look at 60ft times). Or more likely it’s exactly the same because those slips are virtually identical.

The time difference between the two 60FT numbers is within a few 1/1000th of a second of the difference between the times for the two 1/8th. That's probably where all the help is coming from, a somewhat less intrusive, more optimistic about traction T/C is giving it a slight edge off the line. Given that the other main thing that Track Mode does is have A/C running full out all the time, that roughly 6kW draw off the high voltage lines may indeed slightly drop the power available to the drive train?

P.S. As an AWD owner, the very similar 60FT times for the AWD vs RWD is something of a sad surprise. Still, past 60FT the AWD clearly makes bank.

But clearly we can see that physical power draw limitations are not a constraining factor. As the times are nearly identical with the AC/Coolant pumps at max power draw on track mode. So the limitation is software based (amount of power the motors are allowed to draw).

As the times are nearly identical

The trap speeds are not. It's small, and maybe just other unaccounted for conditions, AKA noise, (runs are 1.5hr apart so lots of candidates there) but the 6KW might drop the VDC just enough to matter.

It's also maybe the case that the faster 60FT means the acceleration curve itself is shifted down the track a bit, thus they'd hit the speed at the same point in time? Just not in the same place?

Here's a base line of a Model Y long range 1/8 that has the Ghost upgrade. For the folks wanting to know about adding power to the LR M3, if you have the 980 motor, it is possible.
