Extreme example, but imagine if the car weight was 10,000 lb; more tq will be needed to move it from rest, & that is going to result in more c'ter slippage to get the needed tq....& higher stall speeds.
That is a function of engine torque input.. Yes more engine torque will result in a higher stall speed.
Give it more or less throttle and you get more or less stall speed.
The car weight is irrelevant. It is souley about how much (engine) torque is applied.
(assuming the tires do not spin)
You can test this on any or many auto trans car. Test the launch stall speed at WOT. Now do it again but limit the throttle. The stall changes.
Now add weight to the car and repeat 200lbs 500 lbs 1000 lbs. The stall speed will be the same.
The only thing that changes it is engine torque input.
Start in 1st gear or 2nd or 3rd gear ( manual valve body)
the max WOT launch stall speed will be the same.
