The FE header tank has a baffle running horizontally with a large hole directly below the filler neck. My car's "sweet spot" seems to be just under that hole, which is close to the bottom of the tank. Is that hole the "cold full" level ? No matter how much water I put in, after a run the level is always just bellow the hole. The rest is back on the road somewhere. This is not acceptable if you track or autocross.
