I didn't try to boil race gas, but it solved the problem I was having. I eventually went to a return style fuel system on the car, and re-routed the fuel lines to keep them away from the engine as much as possible, and that solved the problem. FYI the fuel was 92 octane with 10% ethanol. Race gas would certainly boil at a much higher temperature.
New cars don't need to worry too much about the boiling point of the fuel, because with direct port injection used on new vehicles, the fuel is under pressure right up to the point where it is injected into the engine. 45+ pounds of pressure raises the boiling point significantly. The problem I was having was a heat soak issue; I would stop the car, the fuel lines would get hot as the underhood temperature went up, then when I started the engine again after about 20 seconds the hot fuel would go through the needle and seat, lose pressure from the fuel system, boil, and spit out the carb vents, flooding the engine. Took me a while to figure it out, it seemed like the engine was fuel starved, not flooded, but finally one day I duplicated the conditions while the car was sitting in the driveway, and watched it happen. The amount of fuel spitting into the carb was rather remarkable...
