where does your car idle at? where are you're floats set? after coming out of the burnout are you slamming on the brakes? all that fuel sloshing around upsets the engine and it will die. You may need to extend the vent tubes alittle. I run my idle speed up around 1500 so it wouldn't die and I come out of the water box easy. You should put it in neutral and clear the engine out before you put 'er in the beams.
