How significant does acceleration affect fuel distribution and HP?

I don't know about the atomized fuel after the carb, but I can tell you it can cause problems in the carb fuel bowl. Under large G forces the fuel can all run to one side of the bowl and uncover the jets, and it results in fuel starvation. Some carbs have baffles to prevent this - other solutions as well.

At the London car show last year there was a fellow that was having this problem. He would launch and the engine would stumble bad. Second gear was a slight stumble, and then it was ok. He ran over and over again. I wanted to suggest he try raising the float level, but never got the chance.
