Left front brake caliper not holding.

Rearend being slightly out of square with the car could do it also.

I would agree with above about corner weights.

Does it do it everywhere or one track? If the track has grooves worn it can move you sideways.

Get it on a good alignment machine. My guess is the rear end is out of square. As stated in a post above.

4 link car?

Have you swapped rear tires side to side?

I have checked rollout. They are within a 1/4” of each other

There are so many things that can cause the rear to steer one way or another during a burnout.
I would definitely be checking to make sure your rear end is squared in the chassis first. Second, I would be taking a good look at your corner weights. Especially since you said the back of the car is washing out to the left. Typically, you would want more weight on the RR. This would make sense in your situation. Is this a 4 link car, with anti-roll?

Yes it’s a 4 link but NO anti-roll

this does not seem right to me.

I try to get 50# heavy on right rear with no one in the seat. heavy on left rear doesn't seem right.

ep-others may know more about this.

This. With that much weight on left rear I would say if you are pulling big wheelies it would be going to the right. Scale it get more weight off the left rear tire and it should work better.

"Dunning-Kruger Effect"
-a type of Cognitive bias where people with little expertise or ability assume they have superior expertise or ability. This overestimation occurs as a result of the fact that they do not have enough knowledge to know they don't have enough knowledge.

Before you argue with someone ask yourself, "Is this person mentally mature enough to grasp the concept of a different perspective?" If not there is no point to argue.

This car does NOT pull the wheels. This is scaled with me 235 lbs in the seat race ready

I figured it was not pulling the front wheels or it would go to the right. I think if you move some weight off left rear it will fix it.

That is assuming it is not a problem with track not being level.
