Max useful car weight - Indian Princess

[MOSAV]

Indian princess PWD derby comps allow 11 inch long cars and a max weight of 12oz.
Would it be true that a car would still be best off not weighing over 7oz?
I believe I remember hearing tests and equations indicating weight over 7 oz. does not help a car.
Any thoughts on the optimal weight to plan for?

Not according to 5kids sons test. Mo weight mo betta.

It looks like the weight thing may be dependent on what you are using for lube.

Graphite: Max weight ~6.5 oz.

Oil: Weight limited only to the ability of the wheels and axles to support it.

Kinser,
I looked over some other posts. "how much weight is too much" by Oxford.
I seems like multiple people think if your on typical/standard BSA wheels 7oz. is the sweet spot and slightly more if on bearings. The competition I reference is on typical BSA wheels.
Is there a thread I should read from 5 kids?

My results HERE

Before I tried it myself I heard multiple racers say there was a maximum weight.... I never saw any proof other than people saying it... Maybe somebody just said 7 ounces or 9 ounces and everybody else just jumped on the bandwagon and kept repeating the bad info... maybe it was for graphite cars... don't know... I know for a good builder, on oil, you can go heavier...
